Hey guys,

Took my SUV to the track again this past weekend to see what the 100 octane tune can do. This is probably good for those with LMS to see what you can do on 100 octane vs. 93.

Previous best was 13.384 @ 102.14 on 93 octane.

Were you running straight 102 Race Gas or a mix - I think our edge will get around 13.3 on a 93 Octane- as posted did a 13.5 and it has less than 2000 miles on it
Also what was your launch rpm -

Straight 100 gas. I launched around 2100-2200 rpm. I did re-flash the tune right before heading to the track so I am not sure if the ECU had time to learn the car to make the best run, but who knows

What's the best way to make sure your car is using the higher octane? Do you need to reflash, or will it make adjustments over time on its own with a few miles? I'm guessing a few WOT romps would let it know it's got some octane overhead, but I don't know.

run the octane your tune is set for. GT states he was on a 100 octane tune instead of the 93 tune.

I would think the computer is always advancing the timing until it detects knock, then pulls timing.

I agree, at least to some degree. That's how you can run 87-93 stock. But a tune focused on one octane would be better, and certainly required for 100 in my opinion.

Hurrdurr... somehow I must've glazed over that part...
