ECU upgrade results/feedback
[quote=steve@digitalho;1671042]
Good post and see you soon Steve!
I am ready to do the ecu upgrade on my 997 gt3.
Not intersted in doing the exhaust at this time.
Since your in LA you should see Mike at Stuttgart Performance. He is having very good results with REVO programmable sofrware. The program for stock gains 12 hp. He can drive it and perform actual on street tests to adjust it exactly to your car and fuel. He did my car which had headers and light weight silencers. He was able to make adjustments to throttle speed settings, fuel and timing. My motor needed lot's more fuel to make power with the exhaust. Throttle speed made a big difference. The motor rev's much quicker and the throttle is lightning quick. It only runs about $1,200.00 My car now run's strong only because we were able to tune it on the street. I highly recomend both REVO and Stuttgart. Fabrice at GMG can also provide you the GIAC Software. It will get you there with a stock car. Any mod's and REVO allows you to tune on the road "real conditions" to your car's exact charcteristics and mod's. Good luck, Steve

Hey GT3PTY did you get the AWE header/exhaust system? If so you need to give us feed back.
Frankly I was not impressed w/ it. Little weight savings and their claim is 10 hp gain (assume rwhp).
Would love to hear better feedback and dyno results from you. You must dyno. All the systems sound good and strong so that's not enough. No butt-dyno.
Good luck w/ it and post results
Cheers,

Hey WyattH let me tell you from personal experience. I have advocated the FVD headers and for the price they are unbeatable!!
Do not consider the FVD software, it offered nothing except a waste of money which I got screwed. Later they were giving the software for free, go figure?
That's not just my opinion but my facts w/ my GT3.

Ranger - Thanks for the input. What exhaust do you suggest to go with the FVD headers? I am getting some units confused - were the FVD the same length as OEM with 200cell cats (I think it was AWE that was longer and needed new exhaust)?
Does your exhaust keep the valves for sport mode?

Thanks guys for all the reply,
I am making some phone calls today to figure out costs etc.
I am reluctant to do the exhaust because of the noise factor, even though I love it it attracts the wrong kind of attention.
So far it sounds like GIAC has the best software from what I am hearing.

REVO Dyno Chart

Here is the REVO Dyno Sheet for a stock motor. When I ran it I could notice the difference but not that much. I run Cargraphic headers and lightweight silencers. After Mike performed some tests on the road he was able to add a bunch more fuel and slightly more timing advance. When he set the throttle speed setting on next to the fastest setting it was amazing ! The motor got deeper and pulled so much harder in mid range all the way to 8500 rpm. All the guy's who put exhaust systems on must increase the fuel curve otherwise it will run too lean and hot. With the 91 octane, you can use every bit of fuel you can get and boy did my motor like it. It starts better, and now the car shakes slightly at idle. That's HP ! My advice to all you GT-3 guy's ? Your cars are running too lean, give it more fuel so it can work for you ! The color of my exhaust is telling me it's running just about as good as you can get it on pump gas and it's still not dark ! Best regards, Steve
