Probably bugs, delays, or just plain busy. =/ was hoping for the 2017 tunes myself

Last he emailed me back and said that the 91 tune was aggressive (meaning there might not be a 93 tune:thumbdown:) And apparently the most recent 91 tune was the same the beta tunes(not from him but other members who compared). He wanted my datalogs but I wanted to wait until an official tune was released (guess that is delayed).


But if he ever reads this I would be willing to send datalogs back and forth so we have a REAL 93 octane tune. Otherwise your basically spending $500 to turn off cold and o2 codes.

Sorry not familiar with GM ecu logic

I think the 17 can handle more power than what is being offered here. Top end is feeling more anemic than my 93 octane tune from my 13 brz.

That's probably because the top end is at 11.02 AFR :mad0260:

if im running 91tune with top end at 11AFR does it mean i can try 93tune to get it close to 12-13 AFR?

No, fuel quality, or octane will only affect it's ability to resist knock, it will not change the amount of fuel that the ECU is currently commanding in relation to air(AFR).

just waiting for the new tune to come out and give it a try haha

Just as I thought, commanded AFR when it's down to 11.02 is 12.12. But I don't think it's a scaling issue because the commanded AFR is 12.12 when the actual AFR varies from 11.6 down to 11.02 while the commanded stays the same. So there's something up with this tune. I'm wondering if he doesn't have the newer tables defined at all? I feel like things wouldn't be working at all in that case though.

OFT as a company is really focusing on another platform right now. This service for the 2017s is to keep support.

Not a good excuse they still had no problem taking my $500

I didn't post to make an excuse for them. I am saying out cars aren't their priority. Far from and excuse. The 2017 has a potential not being met by old firmware and software.

Didn't mean to come off as a Dck. We are on the same team here. So you think the device itself is incapable of a better tune? Or is there just not enough voices interested or ticked off about the attention given to the 17 tune?

No, that's exactly what a MAF scaling issue looks like.

When you are open loop the MAF value determines how much fuel is delivered in order to hit the commanded AFR. The fact that the measured AFR is lower means that the MAF scaling is off.
