New to EFILive, Help increasing AFR

Ok, we didnt know you already had the 2002 OS loaded. If you have the 12212156 OS now, then ignore our last posts. We assumed you had the stock 2000 OS. It doesnt matter what the OS was before at all now, 12212156 is THE one to use.

Joe and I assumed: 2000 OS with VATS, EGR, etc removed.
Actual: 2002 12212156 OS with VATS, EGR, etc removed.

The files we posted are for 99-00 guys who are still running their 99-00 OS and want to migrate to the 2002 12212156 OS, basically a forum member took the stock 12212156 OS and ported the 99-00 values into it so anyone wanting to do this swap has 1 less step (copying the 99-00 tune to the 02 one).

Dont worry about the 99-00 differences, since you have a 00 engine compare that with the 2002 OS.

Hopefully that clears it up a bit.

Yes, Actual: 2002 12212156 OS with VATS, EGR, etc removed is what I currently have along with the following modifications:

2000 Camaro Z28 M6
LS6 Intake Manifold
K&N Intake
Custom 3" Magnaflow Exhaust w/ EGR/AIR Delete

If I understand correctly, you are suggesting I ignore the differences between the 1999 tune and the 2000 tune because the difference is minuscule and would be more or less be irrelevant. Then move on to using the migrated 1999 tune from filedepot because it should provide a better base for tuning since it more accurately matches the physical characteristics of my engine? So in short this is what I should do...

Acutal: 2002 OS with 2002 Tune
Reflash with migrated 1999 Chevrolet Camaro M6 12212156 Calibration Tune from Tunefildepot
Change VIN to 2002 Tune
Remove VATS, EGR, CAGS, etc.
Begin Tuning from here.

I would compare a 2000 Camaro file to the current 02 OS you have and change it accordingly (VE and spark tables mostly), then Calc.VET it and go from there.

[sonicgroove]

Is there a particular reason you suggest to compare the 02 to the 2000 vs the 1999 and 2000?

Because you have a motor out of a 2000, not a 99. The end goal is to have the 2002 OS with all the settings of your 2000 OS (that matches your engine). Then, you can proceed to tune your vehicle.

Run the migrated file and see how it goes (the differences are small enough to be safe).

I already copied over everything I could from the 2000 calibration to the 1999 migrated file. Everything emissions related was changed to the 2002 settings. Some tables could not be copied over because some setups used different calculations on there maps not to mention there were extra tables between the two. I hope this doesn't matter considering the difference between the two calibrations are minor.

I plan to pick up a NGK AFX today, any thoughts on running this wideband with efilivev2?

On a side note, I really wish we could compare calibrations from different operating systems. It would have been nice to create a script and run it.

NGK will connect to V2 using analog interface...

Look at decal on lower edge on back of your V2, see orange connector, labelled AD1+ and AD1-, your wideband signal output and signal ground connect here.

Loaded up that calibration. Runs just as smooth as the previous setup however still get knock readings on the log files. I have no way to measure the afr to determine if I'm still running rich but I did buy the ngk afx. Going to try and get it installed sometime this week and get some logging done and perform a calc.vet

Post some log files (showing knock).
