FC Tune preview
 

If you have read this thread you know that i am working on a replacement software for FC Edit.

The Honda version is almost done so i thought i post a preview. Do not use this version to tune your Power FC, only about 75% works for the FD3S.

You can download a preview here:
http://www.fctune.com/download/FCTune_0_35.exe

FC Edit Honda file:
http://www.fctune.com/download/B18Cv4.10.Dat

You can also open an FD3S file but some settings will be displayed wrong.

There are a total of 128 models and i have to do them step by step now.
The FD3S version should be ready by the end of the month.

Again: This is a preview, not a release.


Andre

Woo, exciting! Eagerly awaiting a Nissan version. Whats the progress like on the box end of the project?

These are the scheduled release dates for the software:

07/17/05: Honda
07/31/05: Mazda
08/07/05: Nissan
08/14/05: Toyota
08/21/05: Subaru
08/28/05: Mitsubishi

FC Tune is free and is a drop in replacement for FC Edit. I will also permanently add new features to the software and i will install a forum on fctune.com where everyone can request features.

The box should be ready in august. There will be 2 versions, one that is just a direct connection between the PC and PFC and one with an additional connector for the Commander and 2 Step Revlimiter, Anti-Lag, Gear based ignition and injection, Shift light, Boost Switch, Analog inputs that can used to correct ignition and injection (EGT etc.). Target price is USD 199. Compared to the USD 399 for the Datalogit that's a fair target price i think and a 50% drop for a better box and software (i hope you like FC Tune better than FC Edit).

But i don't want to advertise the box here, actually i never wanted to sell a box but i was asked many times to do it.

I would appreciate some feedback about FC Tune. Do you like the user interface with one window for each setting? I will also make 2 tabbed windows with all fuel and ignition settings.

Just some basic comments, would be nice to have each button have a popup label on mouseover. I see right now the fuction is displayed in the status bar at the bottom but this only appears when you click and hold down the mouse button on a function button. I think the interface would also look a little smoother if windows such as Rev/Idle were an exact size to display the contents. Since this window is not resizeable anyway, might as well make it only big enough to display the data instead of having the extra border around the cells.

I do like the individual windows as opposed to the massive tabbed pages of fc edit because with the windows you will be able to compare multiple features of your choosing side by side instead of having to constantly switch between tabs.

I really like the fact that the row and coulmn header both depress when you select a cell so you can see its exact coordinates. Dunno if fc edit is like this as well but its very helpful.

Also 3D map displays would be nice but I think I remember you mentioning it was in the works.

very impressed, good work and no doubt endless days spend coding this lovely interface. you will make lots of people using the powerfc very happy im sure :) cant wait for nissan release

Added support for 13B-REW:

http://www.fctune.com/download/FCTune_0_40.exe

Please try to download the calibration from the PFC and save it as an FC Edit file and than open it in FC Edit and let me know if it works.

Maybe i should skip the RX7 version and work on the Nissan release instead. So far 100 people have downloaded the software here but no feedback.

Maybe everyone waits for the final release but it doesn't work like that, i don't have a garage full of japanese brand cars.

All you have to do is to select the correct com port under "ECU > Port", than "ECU > Download calibration" and finally "File > Save as" and you should be able to view your calibration in FC Edit and most settings already with FC Tune.

Maybe because when I open it, it says HONDA and is not Rx-7. Or how about the fact that displays are more cumbursome than the DATALOGIT software.

What will it do for me that the DL can't do better?

I've made the message because the software isn't tested on any other car yet and some displays are still wrong for the RX7.


The displays are more cumbersome? Please explain.


Any constructive comments? I've said i will try to add any feature requests to the software.

Just to let you know which settings are all displayed wrong in DL:

- Turbo transition
- Injector warning
- Knock warning
- Injection vs. TPS
- Injection vs. Accel TPS1
- Ignition vs. TPS

Also the recalc base function has a bad side effect. Water temp. correction has additional settings.

There are also more settings:

- Idle Ignition Timing
- Fuel Cut Recovery Ignition
- Fuel Cut
- Fuel Cut Recovery Enrichment
- Injection vs. Decelerate TPS
- Idle RPM vs. Water temperature
- Idle Air

I do not like the totally Windows look to find all the tables. Not user friendly.

At leaste the more frequently used maps should be in a format similar to the DL format. Displayed major screens with the TITLE visable which does not require hunting.

Also you have to pull down every little map one at a time. Similar maps all should be on the same page.

That's what I ment by cumberson.

If you final product was such improved, and is more accurate and has more missing functions, I would be willing to pay a resonable price for it.

I'm not looking to make money with the box or software. The software is free and everyone with a Datalogit doesn't need a new box. The box without additional features will be sold at cost.

I've spent more than 500 hours in the last 7 month coding 20,000 lines of code and i've got no support or feedback so far.

You complain about the message box, but how can i be sure everything works if nobody tests it? Buy an RX7?

If you don't like the software that's fine, but let me know why so when can work on it ;)

Another advantage of FC Tune is that it is portable to WinCE, Linux and even Mac.
You'll never see FC Edit for a handheld.

It would be great if someone could try to read the settings from the PFC (Download calibration) and then save it as a FC Edit file. That doesn't change any value in the PFC.

Also check out "Injection vs TPS voltage" and "Ignition vs TPS voltage" and you'll see what FC Edit displays wrong.

Fasthatch,

I'm an Impreza owner in the UK and have recently had a Power FC fitted and mapped. I have read your thread and am very interested in what you are trying to achieve.

Is there anything I could do in terms of testing or research in order to help you out or develop the Subaru strain of the FCTune.

I am currently looking into converting one of these home made kits that normaly reads from the OEM ECU to display real time data to one that is PowerFC compatible.

www.scoobymonitor.co.uk


Do RX7 owners have data moniotors other than the commander?


Wayne.

If you have a Datalogit box you could help me in the next weeks. The Subaru uses an air flow meter and i haven't finished the windows yet.

An Atmel microcontroller with an I²C slave would work for this purpose. Only problem is that the Atmel only has 4 KB of RAM, that isn't enough to store the PFC calibration but enough to monitor the sensor values. But why?

Just finished the lag time, dwell and ignition vs. water temp cold windows for the RX7.

RX7:

All views are dynamically, not one app for each model like FC Edit.

Version can be downloaded here:
http://www.fctune.com/download/FCTune_0_41.exe


Does FC Edit highlight changes and has an undo history?

If your looking for someone to test the box with the extra features consider me in. I have not gotten a datalogit due to demand but will wait for this box with all the extra features. Plus I want something to run on Windows CE. Looks good can't argue with more features and FREE.

Thanks

Just wanted to add something else minor, I noticed in the early screen shots you posted the maps cells had color gradients which I think is helpful for giving you a visual cue as to what the map will look like at a glance.

Good eye there, that feature will be included in the next release. Also the view can be switched beween pulse width and injector duty cycle and the fuel correction map between correction value, target lambda and target AFR (Can FC Edit do that? ;) )

I also want to add wizards so that you can select your injectors etc. from a list.

Keep up the good work. There are people who appreciate your work here on these forums.

cant wait to see your finish product. good luck

The ignition map and fuel correction map cells are now colored:

http://www.fctune.com/download/FCTune_0_42.exe

Let me know if you like the colors. Maybe i should make a dialog where the colors are user definable.

I have also made some fixes for the RX7 version:

- Base fuel map shows the correct breakpoints
- Ignition map shows correct vaules, piston and rotary engines have different values

Except the injectors window and the strings in the protect window all other windows are now working for the RX7.

Wow, I'm impressed you've made it so far with this. Last time I had been on the forums, seems like it was just an idea you were investigating...

I could definitely be pulled away from the FC Edit software as it seems to have gone stagnant. My only concern would be bugs in the software that would result in popping an engine. No personal insults indended there...I'm a programmer too, so I know bugs are inevitable. ;)

By the way, I REALLY like the colors in the maps a lot. And I like that you're planning on releasing this as free software. If this works out, you should set up an account for donations as I'm the type that would donate some cash back for your efforts...

I'll download my maps from the PFC tomorrow and compare in FC Edit for you...

I am working since last december on the software and have spent countless nights and weekends long before i have found this forum.

You are right, every software has bugs. I am working since 5 years as a software developer for a multi billion dollar company developing car navigation systems. You can trust me, the software is very well designed and written. Feel free to visit me and have a look at the source code ;)

A funny thing is if you can get in touch with the developer you assume it has bugs, if it's an anonymous company in New Zealand you assume it's bug free.

The communication protocol has a checksum, so it's nearly impossible to send bad data to the PFC. So the only dangerous bugs would be the conversion from real values to PFC values.

I also had the upload/download function running in an loop for an hour and it hasn't crashed.

Also FC Tune checks the lower and upper limit of each value which FC Edit doesn't do. Enter '9999' for the different settings and you'll see what i mean. FC Edit only limits it to the maximum that fits into the variable.

I also add other checks to the software, the order will be checked (ascending/descending values) and the cells will be compared with its neighbours.

http://andre.honda-tech.de/fctune/limit.png

wow. very impressed. /clap keep up the awesome work. Its much appreciated.

http://andre.honda-tech.de/fctune/seqturbo.png

Version 0.43 is available, added

- Leading ignition map
- Sequential turbo

http://www.fctune.com/download/FCTune_0_43.exe

Please let me know how you would like to have ignition split displayed. Extra read only map? Or should the values be editable and Trailing is than Leading - Entered split value?

i'd vote that you can change the split values... this will help new users starting out to get 15 split in all boxes. also it will help save time while tuning for max power.

If you enter a split value, should i set Trailing = Leading - Split or Leading = Trailing + Split?

P.S.: If someone has already download v0.43 please download it again, it was set up to work with my own box and not the Datalogit. Sorry.

IMO i think you should make it Trailing = Leading - Split. because most people will probably do their leading b4 their trailing. just seems like leading should be the main one.

Wow, what can I say, I'm very impressed. Your response eases my mind a lot. Until you know otherwise, you basically have to assume people don't know what they're doing. There's a lot of people just calling themselves programmers... (again, no direct insult to you, just saying in general) :)

The only reason I trust FC Edit is because it's been tested by so many people. I'm generally leery of beta testing when it comes to my car's engine. ;)

Glad to see you're doing this in C++. Should be a lot more efficient than the VB6 of FC Edit. I assume you'll try to have logging capability at some point? That's one of my gripes with FC Edit is that I imagine the code isn't optimized. I'd be willing to bet you can get more than 10 samples per sec out of the PFC, but I could be wrong.

I also agree that you should be able to edit split directly. And it should be Trailing = Leading - Split. That's also the way FC Edit works.

Also, something I use in Edit all the time that doesn't appear to work in Tune. If you select a range on a map, and then type in a number, it's nice for that to adjust all the numbers in the range. For example, on my fuel correction map, it's common for me to select an entire P-row, and then type in 1.1 to add 10% to that whole line. Hope that makes sense.

Thanks for your response and like I say, that has greatly increased my confidence. Extremely nice software so far. I'll be glad to do whatever I can to help! Like I say, I'll do a download tonight and compare with Edit and post the results tomorrow.....

You can do the testings without the engine running, so there is no risk. Make a copy of your calibration and write it back when you are done.

*hint* You can also connect two com ports with a null modem cable and then start FC Edit and FC Tune, FC Tune emulates the Power FC *hint* ;)

You can change some values in FC Tune and then click "read all" and you'll see your values in FC Edit ;)


Actually only the Win32 stuff is in C++, everything else is written in ANSI C. The reason why i made this is the portability to microcontrollers.

Even the windows are not Win32/MFC code, i've made a generic interface with InitView, QueryValue, QueryString, UpdateValue, ...

InitView describes the columns/cells (value type, number of digits, packet id, lower and upper limit) and than the grid calls QueryValue for each cell or UpdateValue if a cell was changed.

You can't even enter a character that is not valid for a cell. If you enter "a99" in FC Edit it result in a 0.

http://andre.honda-tech.de/fctune/valuetype.png


Logging capatibilies are already built in, but i don't know how to display the values yet. FC Edit has it all on one page. Should i make one window for each block of monitor data? Bar graph? Line graph? Only a textual view?

The logging rate is limited due to the baud rate. Although the baud rate between the box and the PC is 56000, between the box/Commander and the PFC it's only 19200. More than 10 samples a second won't be possible.

But i'll save the logging data binary, that makes it possible to add built in logging on the box.


I'll have a look at it tonight.

How can I help with a Mitsubishi Evo?

Regards,
EvoErik

Wow, with every post, FastHatch, I'm more and more impressed. :)

That's REALLY slick the way Edit can talk to Tune. NICE! And yes, I had already thought about mitigating the risk by doing another write from Edit to the PFC after using Tune. My only fear was that Tune apparently accesses some data that Edit isn't aware of. But that's minimal, so after hearing more about the inner workings, I'm feeling a lot more comfy about it. :)

Good job staying away from MFC. Portability is a definite plus. And it never hurts to stay away from MS (which is ironic for me to say since I'm a lowly .NET programmer...) But on the other hand, if you need any fancy Windows GUIs I can definitely help. :)

Tough call on how to display the windows. I initially wasn't real fond of the way all the settings are in their own windows. But I think that was just from me being used to Edit. As long as you allow the user to save the window positions/sizes (especially if it's into different files) that would probably be better in the long run. However, for a Monitor type screen like Edit's, there's probably no reason not to just put that all on one screen, or break them out into Basic/Advanced. Hard to say, might be good to get other people's input on that one. However, one MUST for me, is that the logged data can be displayed on a map like in Edit. For example, I constantly look at my average AFRs overlayed onto the fuel map grid so that I can quickly tell exactly where I need to go to change fuel. The other function I frequently use is the line graph, such as AFR vs Time and RPM, for example. Those are the two I'm looking at while I'm in the car. The rest I can do at home in a spreadsheet with just raw data files....

Too bad about the logging limitations. I knew the baud rate would be a limitation, but I thought maybe you could get better sample rates if you had a way of only selecting the exact data you wanted to log. Edit forces you to log all of Basic, or all of Advanced, etc, so there's a lot of data saved that I don't even care about. Wasn't sure if that's how the PFC forces you to pull it, or if that was just how Edit was written. However, I also run Edit on a slow laptop, so I don't even get the full download rate, as seen by the commander being able to still update itself while I'm logging. I'm betting your code will run more efficiently on slower machines....

One last thing...hoping you're planning on being able to log from the AN inputs on the datalogit box??? Obviously, logging from my wideband is very important.

Again, I'm EXTREMELY impressed! :)

Andre,

I just finished checking the 43 version against my FC_Edit.
All data matched for the shown maps that are also on the FC_Edit.


Have you come across any code that affects fuel based on TPS setting vs time or just time? https://www.rx7club.com/power-fc-forum-47/anyone-know-about-pfc-entry-434278/

Just finished verifying everything. Things I noticed:
* Injection vs Air Temp (hot) also has a boost associated with it in FC Edit
* Injections vs TPS voltage: TPS voltage is displayed as a percentage instead of voltage (same on others)
* Inj vs Water temp (Cold) was 0.001 off from FC Edit...no biggie, obviously
* Inj vs Water temp should also be tied in with a boost
* Ign vs TPS is all 0's in Tune and all 1's in Edit

And just to be sure, I also did a full read with FC Edit before and after doing a read with FC Tune, and everything was the same. :)

Hope that helps....

Hi FastHatch,

The problem with me downloading my maps is I, probably like many others don't have the cable required to hook up comXYZ to the commander port. If I had of had the cable I would have done some testing with my real map data and compared what I had found but alas I can't cos no cable.

I've had a look as kashima's cable schemantics which covers the cable and parts needed. Do you know if this cable/dongle works with the software you've done. Ive noticed you can choose which cable/dongle box but they are all greyed out on my pc when I launch FC Tune.

Thanks for update, I've been away but I am back now and ready to assit where I can (well with nissan skyline version)

once again awesome work

I also meant to add a couple more things to my post...

1) When you save the dat file in Tune, if you don't type ".dat" it doesn't add the extension
2) Reading the file saved by Tune back into Edit worked perfectly, with no differences displayed using the Compare function from a file saved using Edit. I think that's what you're original question was asking for us to do...

Right, also some other settings have MAP values associated with it were Edit doesn't display them. But i have to admit that i don't understand these values. First, they are not boost, they are absolute pressure. Second, i know they do not limit the max. boost, they correct the target idle RPM for various conditions. I have absolutely no idea what these values are good for. Idle air?

FC Edit is faulty here. The values are TPS voltage from 0V to 4.980V. FC Edit interpretes 0V as 0% and 4.980V as 100%. That's wrong. For Hondas it is 0.5V = 0% and 4.5V = 100%. 0V and 5V is used to detect a bad circuit. I know the Mazda ECU does the same.


FC Tune rounds and does not cut off the values. But i check it again. But honestly, who cares about 0.001?


Again, FC Edit is faulty here. They had no idea how to interpret the values so they used the same as for injection. Honestly, what shoud do a value of 1.245 do to the ignition? You can either retard or advance the ignition.


Thanks for testing.

I don't think anybody else does either. I'm not aware of anyone even messing with these values...

No problem, let me know if there's anything else I can do to help!

I'll release a version that supports monitoring/logging in the next days, would be great if you could test it then. Also if someone wants to paint an icon (16x15 pixel, 16 colors) for ignition split i would appreciate it.

I hope you feel a little bit more confident now to use the software.
I'm also using a linter (PC lint) to check the source code for potential failures. And every structure and function is completly documented.

http://andre.honda-tech.de/fctune/linter.png

My sad attempt at ign split. 16x15 is a little constraining :)

Well I personally like the icon. Pretty clever. :)

I'll be glad to test the logging as soon as you release the next version.

And yes, I DEFINITELY feel more confident using the software. You've definitely proven yourself to be thorough! :)

After 3 days working almost the whole day and night on FC Tune some features are done now:

- Multiple grids on a view
- Cell merge
- Radio buttons in grid

http://www.fctune.com/pics/staged.png

As you can see above Injectors, Idle Ignition Control and Pressure sensor settings are now done.

http://www.fctune.com/download/FCTune_0_50.exe

The merged cells have some minor drawing "bugs", you can see 1 pixel of the grid lines in the cells and the focus rect is sometimes 1 pixel to small. But that doesn't affect the function of the cells, i get that "fixed" tomorrow.

What i also don't like is if multiple grids are on one view and you click through the grids every grid has a focus rect and you don't see which grid currently has the focus. I'll "fix" that tomorrow.

Please let me know how you like the views and if you can find any bugs or issues.

I can't promise anything but i should get done everything else within 1 week.

Are the boxes still on schedule for August? Also how much time will it take to get fc tune ready for Windows CE once its complete? Looks great so far. Keep up the good work.

Looks great! One thing I was impressed with was that I noticed in your screenshot that there were commas instead of decimal points. Thought us Americans would just have to deal with that but now I was pleasantly suprised that either you gave us a different version or it pulls from Windows' international settings. Nice.

I like the new windows. Only little bug I noticed in addition to what you mentioned, is that on the pressure sensor window, as you click each radio button, it changes the color of the box. As if it were highlighting that you selected it, but it doesn't set it back to black when you change it again. No biggie, just thought I'd mention it.

Again, nice work. We appreciate it!

Beta testing should start in August.

Each cell (column) has a different NUMBERFMT.

The red cell text means that you have changed the setting. If you click undo the text will go back to black. The behavior you describe is not a bug. Maybe it's a bit unclear with radio buttons.

Still needs some work, but FC Tune runs on Windows CE :)

I may have to use shorter header captions and a smaller font, but you can see the advantage of one window for each setting instead of a massive page now ;)

http://www.fctune.com/pics/ce/cranking.png http://www.fctune.com/pics/ce/saveas.png

And FC Tune runs on little endian processors as well as on big endian.

Who wants FC Tune for his cell phone? :D

Great work !!!
Are you planning to release a MR2 version too?
