Megan370z

I would also like to see more people sharing their experience with the tuning of the 370z.

I'm myself new into the self-tuning ! Its been a year now that I have the Uprev Tuner kit.
I went many time on the dyno and I learned quite a lot every time about this engine and this damn ECU .
I found out that this ECU is very annoying to tune !
Its quite progressive and self-learning that even tuning it is not an easy job.



Just to give an idea , this is what I was running at the end of last summer with Shell V-power91

This is a very aggressive tune
its was just a guide (average) of many tune to set my tune up .. its not copy/paste from Uprev

6812 12.3 12.3 28 (peak power)
7000 12.3 12.3 29
7500 12.3 12.3 30


Something I would add is even stock, the MAF table could be fine tuned at WOT
I never really bordered about this in the past until I actually get my custom CAI w/ bigger MAF tube.
