i also sort the folder by date modified, so the one you just did is on top.

"if you want to know the easiest way to do something, ask the laziest guy"

 

As mentioned above, I always double check the date and the times stamp on the files to make sure I am flashing the correct adjusted map. I will also then move my dat and txt log files into a "completed auto tune" folder and move my older power FC map into a separate "old auto tune" folder as well. If you leave everything in the root directory, it could get messy.

 

i do that too, although not usually daily

 

Wow, a great thread.
1. Aside from Facebook is there any way to get FC Tweak? or the manual? The link for the manual doesn't seem to work for me.

2. Approximately how long does it take to download a log / adjust and upload?

Very excited to hear that there are options, as I definitely need to make adjustments after adjustments were made.

 

Try this link for the manual, if it still doesnt work I can email you a copy. =AT3cUaGCyJv-PTL4r_FR_By8AWIFSFsYOq42N-8QyY5VqjdDgV86CqDXRaUVeEiAxUAgD4k9fBtJCnpXGETGTr2R j_GUZrCbEgBHuepggzpEAIlwYVJavHoEOWPG5S1af7wTqMoevF 0wONr878aMYxeWI8E6ae3pWjLlbn572AXDPAUVfmCCpGdtqUuV speJ61o0dVus5BglG6QQqLD6TeJ5qdXS-ztGeBtCa0Y]LINK

Xavier has a freeware to mess around with, but does not let you tweak or autotune. It will however show you everything it would change. =AT3cUaGCyJv-PTL4r_FR_By8AWIFSFsYOq42N-8QyY5VqjdDgV86CqDXRaUVeEiAxUAgD4k9fBtJCnpXGETGTr2R j_GUZrCbEgBHuepggzpEAIlwYVJavHoEOWPG5S1af7wTqMoevF 0wONr878aMYxeWI8E6ae3pWjLlbn572AXDPAUVfmCCpGdtqUuV speJ61o0dVus5BglG6QQqLD6TeJ5qdXS-ztGeBtCa0Y]LINK

Regarding how long it takes. If you mean how long does it take to load the log file and have it auto tune, then its literally a matter of minutes. Driving to create the logs needed to auto tune takes the time.

Maybe I should make a little video walkthrough for everyone. Might make it a lot easier to explain.

 

Attached a copy of the manual, he does routinely update the software and the manual so the link above is the best place to get the latest version. It is shared on Google Drive I think.

When you drive around logging with FC-Edit, saving the log out is near instantaneous.

Then you go into FC-Tweak, load the map/log, it takes maybe 5 seconds to analyze the log and apply whatever changes you want. Save the map, then load the map into the PFC. This process takes no time at all.

Thanks @iceman4357 .

Actually am emailing Xavier with some questions, but appreciate your offer. Will teach out if the download doesn't work (it should).

Would you recommend the 'pro version' or the 'standard' version of the software? Any insight into the differences?

A video is always appreciated.

Hopefully this is the catalyst to driving the RX-7 more (and the need to get a quieter exhaust).

 

@DaleClark

Sorry for the stupid question, but can you just download the log into a laptop and then run the software and upload to the PFC without getting out of the car?

And then repeat the process over again?

I have no idea what connector the Datalogit uses.

Can you run it through an adapter for USB or USB-C?

 

Pro version for auto tune.

 

I keep the laptop in my car and do autotune. When logging from teh Datalogit, you will have a serial to USB going to your laptop. Save the log from FC Edit, immediately open FC tune, Autotune the file/export. Then open FC Edit, open the new map and "write" to the power FC.

Then repeat for different cells, or same if your map is really far off.

 

So, the Datalogit is still old school and has an RS-232 serial port. You get a good USB to serial adapter and hook it to your laptop.

You have FC-Edit, the Datalogit software, on the laptop. That does the logging, loading and saving maps, etc.

Then you have FC-Tweak which takes the map and the log and tweaks/autotunes it for you.

So you warm up the car, fire up FC-Edit, start logging. Drive for 20 minutes. Save the log and it saves the map with the log.

Fire up FC-Tweak, load the log/map in, let it autotune, it will save a new map out. Use FC-Edit to save it into the PFC. Repeat.

Yep you can do this 100% driving around. I did one logging session, pulled over into a parking lot, autotuned, loaded the map into the PFC (it takes like 3 seconds to load a map) and went logging again.

Some of the process is kind of odd, I've asked Xavier if he ever considered building in functionality to FC-Tweak so FC-Edit is no longer needed. That may be down the road, right now there's not enough available memory to do everything it needs.

Please excuse my terrible skills at being a narrator, but I made a quick video that will hopefully explain everything a little better. You can see the time/date stamp on each of the files, which is important if you dont create separate folders like I did in the photos below.

LINK for video--> https://photos.app.goo.gl/ThfBRqEhSKDQBFN27



AFTER completing each auto tune, I made a folder that I drop the DAT and TXT files into. This makes FC Tweak a lot less messy and straight forward.

Similarly, after I flash my new auto tuned map, I move my old map into Auto-Tuned Complete.

 

Was able to download the zip file / manual and understand I need to get the Pro version of FC Tweak.
Is FC-Edit available from a link to DL or only through the Google Group?

Thanks.

 

Send Xavier an email about purchasing

Thanks Dale.

Was able to download manual/unregistered program with plans to get the pro version.

Do you run your WB sensor off a bung? or off the tailpipe?

Now just to cobble the parts (datalogit/cables/02 sensor) Looking forward to this project and have not been this excited about getting the RX-7 back on the road again in a while.

FYI Xavier is great at communication, and has been very helpful.

 

Xavier is an extremely patient man lol. He has helped me trouble shoot so many things.

 

​​​​​​Install into your midpipe before the cat. A lot of people put an O2 in the downpipe, which will not last very long with the amount of heat our cars produce. Most O2 instructions recommend 18" downstream from turbo manifold.

 

How do you have your wideband setup Dale? I've got mine setup exactly how Xavier says to do it in the FC-Tweak manual and im still getting the "Noisy wideband ground" & "UEGO range <18.0:1" error. I'm using a AEM 30-0300 with its polynomials set to what the manual says & have tried multiple grounding points.

 

I had these errors among others. Dale gave me some pointers at DGRR on getting a better log session but haven't had time to give it another shot. Interested to see what these really mean and how to correct.

 

5 stars !!!!!!

 

You can find out which errors mean what and how to correct them on Page 79 of the FC-Tweak manual, my issue is that I've tried correcting them to no avail, let me know what errors your getting and I can probably help you out with them

 

Are there any options for using upgraded twins like BNR's?
Or will FC tweak work fine with such a setup?

 

it'll do fine with that. there are two parts to the software.
the Tweak part takes your mod list, and runs through the map looking for things like negative timing split (unless you turn it on), cells where the injectors have too low a duty cycle to be stable, big changes in timing, the idle speeds, fan temps, etc etc
then part 2, the auto tune compares the target AFR map with your log and will make adjustments until it hits the target AFRs (take a few runs)

 

My WB LC-2 should arrive today or tomorrow
The datalogit is in the FD.
Need to get the bung welded on, and then find time to tune.
