OFT STAGE2+ BRZ VALUES LTFT - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

GarrettGalway · 08-11-2018, 07:31 PM

Just tuned my BRZ on stage 2+ OFT with catless headers I am running Shell 91 octane but I have a AEM intake looking at my LTFT they seem a little high on idle at 10% but under load and drive usually around 2-4% everything else seems good and the car seems to be running great!

I am still learning and have lots to learn on it all but I am just wondering if I could get any help regarding proper values because Open Flash doesn't seem to reply to emails regarding tunes and revisions emailed about a week ago with no reply,I can send over a 3000-7200RPM 3rd gear data log if needed any help would be greatly appreciated thanks a lot everyone!

Did you recalibrate the MAF tables for your intake?

Also look at afr vs commanded afr under full throttle

No I did not re calibrate the MAF tables I am looking into the VGI software for that as everyone says its probably the best thing to use just gotta figure out how to use that as well haha. Also my LTFT are always negative -8 to -10 at idle and -5 to -7 on decel, How do I see commanded afr? Also would it be best for me to have a pro do the MAF scaling or is it easy enough once I get the VGI going? Reading up on your MAF scaling post now Steve. Thanks for the input and help guys!
