Just picked up one of these.

Dont get it till the end of the week but just wonderd if any users have any setup tips/tricks like where to connect the RPM and any sugestions as to what else to log appart from O2/lambda and RPM.

Ta steve

 

I got one a couple of months ago. Let me get some info together for you and I will post it when I have the data in front of me.

It is a nice system and the software is very good as well. Getting sensors configured was a bit of a pain and Im still tweaking a couple of components.

Back at you later this evening.

Thanx, will be good to have a little data on setup and tweaking.

 

I'm guessing you don't have a Power FC ECU? I got the lc-1 with the xd-16 guage and wired it all into the Power FC with datalogit software. . .fantastic setup overall!

 

I set up the LM1 and LM2 for:
- AFR
- RPM
- IAT (deg F - my calibration table may be off a little)
- coolant temp (deg F - my calibration table may be off a little)
- MAP (this one Im still tweaking, cant do gauge boost pressure and vacuum on same line - only absolute pressure)
- TPS (% open)

I created quick-disconnect harnesses using computer 4 pin male and female power connectors and a y-connector (these are the ones that plug into your harddrives for power. I tied a set into the ECU wiring and the corresponding set was connected to the LM1 & LM2. This way I wont have to splice into the ECU wiring every time I want to connect the wideband.

The cigarette lighter connection was not adequate for providing 12v power to the LM1. For this, I got a cigarette lighter socket extension cord which I hard wired to the battery.

I used the O2 sensor bung already present on my downpipe for the wideband sensor with an aluminum heatsink plate to shield it from excess heat. When I pull my downpipe next, I plan on placing another bung on the downpipe just before the cat and leaving the stock sensor in place. For my present setup I took an old O2 sensor and cut off the connector which I spliced onto the analog-in wire so the ECU would see an O2 sensor signal.

If you get temp and ohm load numbers for your coolant temp and IAT sensors, I would appreciate seeing that data.

Any questions, let me know.

Some nice stuff there i would be interested in how i get a boost signal from defi link gauges to goto the LMA-2.
Also where and how did you get the tps% and where did you tap the rpm, from the ecu ?
ta steve

 

Unfortunatly i dont have a pfc i only have a HKS F-CON but i have a GCC with it so i can lean or richen through the RPM range.

Apexi Power FC is next on my shopping list.

 

Here's a current log file. I like the LM-1 to log because of the onboard logging, there's no need to have your lap in the car.

 

That looks nice and smooth.
Just got the LM-1 o2 part set up today and mine is kinda jumpy, did the clean are calibration but every time i change gear i get sky hight readings like in the 20s and above, sometimes upto 50 on the LM-1 screen, for now im guessing this is normal as the injectors are cut when lifting (correct me if im wrong).

Also how did you tap your RPM, From the ECU 2B conector ?

Last Question : how do i log Boost on the LMA-2, From map sensor ? (excuse my lack of knowlage on this matter but it would be nice to have someone to pickup the nessasary info from.

Thanx in advance.

 

Right now, my LMA-2 is hooked up to the boost sensor and RPM (both tapped at the ECU connector)

I plan on adding some things like tps% a little later.

 

Ok got LM-1 hooked up to Wideband sensor and all is good.
LMA-2 is now hooked up to the RPM via the ECU 2B wire.
Now i gota find where to tap for Boost, Any tips ?

 

OK am a little confused as people use different terms to discribe the same thing.
Are the MAP sensor and Boost sensor the same thing ?
Can i tap the boost reading for the LM-1 wideband straight from this?
Is it 0-5v and do you think the boost sensor for the AVC-R would be a better place and is this 0-5v ?
Any help would be nice.
Thanx

 

Use pin 1O Green/Yellow at the ecu. In the configure channles, menu set unit of measurement to psi, set -19.30psi = 0.00 volt, and 18.60psi = 5.00 volt

 

Here is a link for the ECU pinout diagrams.

Does anyone have some resistance/voltage data for the IAT sensor and coolant temp sensor that I can compare with the data I have?

I was curious as to where and/or how did you come up with these numbers? I have been having a bitch of a time trying to get numbers that work and get accurate results from my system.

-chuck

 

I just put compressed air to the map sensor and sampled the voltage. I think I used 12 psi for the high and 0 for the low. The software expands the scale to 0 to 5 volt.

 

Thanx guys this exactly what i needed, if you do come up with any more figures on temp conversion numbers then keep us posted.

 

Ok on the LMA-2 i now have RPM, BOOST as indicated above and i have TPS setup but on logworks it says volts, cant for the life of me find out where i can change it to % ....
Any ideas ?

 

You should be able to scale the volts linearly from 0 to 1.

It's been about six months since I looked at it though, so I may be off a little.

 

Yer got it scaled ok just wanted it to say % insted of volts, kinda think that its not on the LMA-2.

Ta anyway .

 

% is there. I vaguely remember not seeing it at first but later was able to get it configured properly with the % setting. I will let you know how I accessed that parameter when I get a chance to look at
Logworks later.

-chuck

 

letme rephrase that.

I scaled some input (as a test) to a linear value by setting 0 volts at 0, and X volts at 1.
