Did I say add , i ment modify. :bonk:

Is it possible to have different timing per gear?

Yes

This seems like a feature alone that would make Ecutek worthwhile. Is it available without Racerom?

No, it would have to be done in Custom Maps.

I was recently tuned by James went i went FI. I have an OFT that I am trying to sell. So if James tunes are unlocked, which I will double tap on, it should be as easy as flashing ECUTEK to stock, then connecting OFT and flashing back stock to unmarry it, and then flashing back my ROM?

Unfortunatly no


James tunes are unlocked meaning you can view and ecit his tunes using ecutek, but ecutek still locks the ecu if a non stock tune is in ecu.

If you flash back stock rom with ecutek it will unlock ecu, and you could write with oft but dont as you will loose yoyur ecutek licience.

Talk to james to see if he could re issue ecutek licience

@steve99 - Is it possible to use EcuTek to log your stock tune?

I want to log my tune to see if I need a custom tune. Trying to figure out if I have to pay the $300 license fee for that to work.

You dont need licience in ecu to log, base pro ecukit will log any brz\86

That is great news. Thank you!

@steve99 - I was able to borrow an EcuTek cable today and do a log. Let me know what you think: https://datazap.me/u/jreifer/2017-br...12-16-21-29-30

Trim the datalog to between about the 8 through 24 time s marks to see the pull. I couldn't figure out how to get this view permanently.

Some things I noticed (I'm a beginner here, so these are more observations/questions than answers):
Long Term Fuel Trim is steady at -1.6 during the pull.
Ignition timing takes a slight dip between 4400-4800 (normal?).
Actual Lambda is about .90-.86 until the end of the run when it dips to .75.
AFR actual takes a second to get in line with the target AFR.
Lambda actual and target take a second to get in line and then are very close.

I'm sure there are a ton of things I'm missing here. Interested to hear your thoughts. Thanks!

Just and FYI AFR Target and Lambda Target are the same thing. Same for AFR/Lambda Actual.

So long as there's no real FLKC (Ign Correction - Fine) then it's OK, but I can't see that you logged that.

It looks like a loss of traction at 6.5k RPM?

Engine load would possibly explain the loss of ignition timing, but you didn't log that either.

+1 on what @Kodename47 said


on stock tune the 02 sensor only reads down to 11.2 even if actual afr is much richer.


look at the throttle their is a big dip round 6400 as kode said look like trac kicked in and closed throttle.


I don't think ecutek logs IAM if you don't have racerom in ecu for some reason.


looks like stock tune to me judging by target afr in 10 range, so looks pretty normal for a stock tune

Thanks, guys! Yes, there was a loss of traction. And @steve99 you are correct that IAM wasn’t an available parameter on the stock tune (no ECUTek license).

@Kodename47 I’m not sure if FLCK or engine load were available as I was borrowing a computer and cable, and it was set up for me with a default set of parameters.

The point of the log was to make sure that going to a 2013-2016 airbox on my 2017 doesn’t necessitate a tune. This swap was needed to allow room for an oil cooler.

I saw recently on Facebook that the OFT will now log 2017 cars, but I haven't confirmed. If the OFT works for IAM, FLKC, etc., maybe I'll get one and do some more logging.
