    2009 G8 race tune

    I wanted to post this up for a review by anyone that would like to see it, basically want honest opinions on the quality of the tune. I haven't been to the track to see what it does over my previous PB of 13.2 @ 107. The car seems to run a lot stronger but I want some exper opinions.

    *note: the tune is for review and use constitutes full knowledge that each vehicle is different and should be used at your own risk.

    I just looked through it real quick, here is my two cents. I usually run a little more timing but every car is different. I would also smooth out the MAF table a little more. It isnt terrible but IMO it could be smoothed a little more. What A/F did you tune WOT? That could be the difference in your timing and mine. I will look through the tune some more when I have more time, those just caught my eye.

    The a/f ratio was an area of concern. The tuner locked in the Stoich A/F at 14.67822 across the board. I've seen others that are basically stock all the way across. As for MAF smoothing, I agree. I will do some datalogging and get that smoothed out with real world numbers. I think another area that I have a weird feeling on is the Spark table, do they seem high?

    Are you seeing any knock retard? What kind of fuel are you running? 87, 91, 93? That stoich AFR is fine. Not sure about the PE AFR as I'm on my mac, and don't have hp tuners to open your file. But some more info would help use let you know the direction to head.
