Updated the new tune, the car is pinging very very hard under load. Ie starting in first gear. Reflashed it to previous tune.....Whats going on??

It's probably leaned it out too much and\or aggressive timing. It just looks like as time progresses each car really needs to be custom tuned. Either they can't get the tune spot on or each car is that much more different.

sorry that it didn't work for you!

i flashed my car at 7pm last night with the new tune and just came home from a drive and it drives very good, it also made very use able low end power. no more bogs, hard starts are gone too. only thing i haven't done is redline it and in full boost! the highest rpm i went was around 5k rpm and i am very sure the power is alot stronger than my previous tune. will update again once i test it out some more.

Seb@SZ

Any plans to throw it on a dyno & check A\F?

Oh yes the new tune feels very nice. Much more power then the previous tune. Throttle response is alot better. And yes, no more hard starts. But too bad the ping. I was watching the replays on my boost gauge and it peaks much earlier also.

Stop driving it (under boost) immediately!

It sounds like you have too much ignition advance and that can destroy pistons, con rods and wrist pins.... to the point of catastrophic fail.

I would first check that it flashed correctly. If you were accidently running the stock 370z tune, it would be doing exactly what youre talking about.

After 8 weeks of missing my lil 370z, it's finally back from Stillen. First I'll post the results, then I'll post driving impressions.

First, I was told by a salesperson at Stillen that my car dyno'd very high in it's baseline form. 315 hp to be precise. This suggests that my car may make more power than some other people's cars....as there is slight variance between each car. It may be because I broke it in hard-and-fast, with full throttle runs to the redline from the first day I owned it.....and tuning with8,100 rpm redline.

My assessment would be that my car is a "best case scenario." Well..... I have seen ONE car that dyno's higher than mine. That is Stillen's press release car. I suggest comparing the dyno chart from page one of this thread to my build.

My build goes like this: '09 370z sport package, touring package, 12k on odometer. Baseline runs were with Stillen G3 intakes, Stillen headers, Stillen hi-flow catayltic convertors, Stillen exhaust. Post supercharger runs were with all of the above mods, except G3 intakes.

green line = baseline.

blue line = 8psi pulley with old tune that ran very rich, didn't start correctly and bogged at throttle tip in.

red line = 9 psi pulley that Stillen used on their press release car with revised93 octane tune (in california that means running 1 gallon 100 octane race gas per 3 gallons of super unleaded).
