Seems that like me, the majority of this board uses GIAC ECU programming. Just wondering if anyone had there ECU done by RS-tuning, which does the tuning for Cargraphic. Also wanted to know impressions.

Also, anyone use Cargraphic coilovers ever, impressions?

 

Lou, you have PM.

Lou,

There is a full RS Tuning 540 HP car here in Chicago. It was actually built in Germany. I have ridden in it and drove it. It had a full cage, GT3 seats, and even the lightweight clutch and flywheel.

My personal impression of the car was that it really was not any faster than a 500 hp car. Maybe with the right 100 octane gas it would have ran better.

The guy lived in Lincolnwood and sold it when he got his GT2.

 

Interesting. I had heard that RS Tuning is one of the only companies in the world that gets a copy of Porsche's program and rewrites the entire program. It is not piggy backed or reverse engineered, but, actually rewriiten. I guess though that if the performance is no different, than what does it matter? Any other experiences good or bad.

BTW, I saw your car yesterday, the guys were working hard at perfecting it.

I have a RS-Tuning 100 octane program on an X50 along with C-Graphic medium exhaust, Bailey DV's and BMC filter. These are the only power mods. The car has been lightened by a few pounds (lighter exhaust, no sunroof, GT3 seats, no spare, Bose sub (POS for sound anyway) tossed etc. I can't give a 2 wheel dyno, 4 wheel dyno or engine dyno readout. I can tell you though, that this car is blazingly fast and will easily run away from a GT2 which is no slouch. I haven't driven a Ruf conversion but acccording to someone who has, this car is easily equal to the Ruf 550hp car. Downside is, it really does require 100 octane fuel which is a PITA.

 

I think that RS Tuning has good stuff and any car making 500 hp will feel fast. The interesting thing that LSM, Shank, and I have seen in our highway testing is that the GIAC, Upsolute, APR as well as some of the other ECU's are all making much more horsepower than a stock GT2 and are all pretty close to one another in Stage II form.

Lou,

My car is supposedly done so next week we need to do some highway testing.

 

Definately. I will tell you, I wasn't there for your dyno runs, but the smiles and laughter out of Todd and Stephen after they finished told me everything. I am sure it won't be close anymore. We'll hook up this week for sure so you can verify me in your rear view I talked to Todd after he was done and they were real happy with the results. Unbeleivable customer service and attention to detail. Great job. BTW, what the *!!??? is up with your exhaust? Straight pipes!!

Lou

 

Uh, next week? What are you doing in an hour?

 

I am still in Scottsdale. That is why I have not posted any impressions of my car. I believe it is in my garage. The proof will be in the pudding. I will PM you on Tuesday or Wednesday for a little Edens pass.
