I have just installed a STS twin turbo kit on a customers 09 Z06. The "tech support" from STS modified the Stock OEM tune file for the vette to complement the new injectors and the twin turbos. I was comparing the stock tune with the STS modified tune and noticed the timing was decreased about or around 10*.
My question is, why would you decrease the timing on the car?
Pretty normal on an FI engine. Especially with stock comp ratio.I have just installed a STS twin turbo kit on a customers 09 Z06.

Thank you.Originally Posted by LSX378
if its a stock motor then how much boost are you running,
then, how much timing is the car doing at 6500rpm, from 0.7x to 1.0x cylinder airmass
im asking because usually there is ALOT left in those FI canned tunes. At least over my canned Vortech tune, which at 5PSI produced 100rwhp over stock, we gained about 50rwhp at peak and a little more at 5500RPMs, and there was STILL room for some more.
So you're best bet is to get it dyno tuned. How do you like the system so far?
We are loving the STS sytem. I am going to make changes to the PE table in a few days and watch the spark table. As on how much boost, don't know yet. Sort of jumped the gun and started driving the car.
Dont get too excited driving the car under boost, im telling you this because this is what I do even before I tune the car lol, stick a wideband in the exhaust and make sure you're not waay off, again canned tunes are meant for the car to run until they get properly tuned.
Please tell me you are not going to attempt to adjust your fueling through the PE table w/out calibrating in the MAF? You work for NASA for God's sake! That would be like raping the tune on space shuttle (sorry, I'm attempting to be humorous, LOL!).

we squeeze our brains tuning cars, i wonder who tunes those space shuttles, and how lol, maybe they use the 2.5bar OS jk.
I live in Huntsville as well and would love to see your car sometime. I'm most likely getting my 2010 Camaro twin turboed in the next few months and would like someone that has more experience with HPTuners to talk with...I work on base too.
I'd be pleased and excited to meet/hang and STS about cars. I'd also be honored to tune your TT '10 Camaro, sir.
P.s. Maybe you can get me a tour of the base?

Hummmm....Are you sure that wouldn't be a -2.5bar OS??

maybe he just services' the shitter on the shuttle? who knows? im sure there are crappy jobs with nasa as well!
The shuttle doesn't have a "Shitter". The space station has the "Shitter". And so what if I do.
LOL! I agree with you....so freakin what?! He works for NASA!
