The proper fuel maps need to be adjusted then the sensors will work how they are designed. Remember this is a street car so part throttle fuel maps also play a role as the wide open section where the dyno runs usually take place. The overall experience should be awesome power with a bit of extra fuel being used so the car still drives like a normal car. How inconvienient would it be to have to fill up every 150 miles just becuase a tuner put to much fuel into the part throttle mixtures. Just my 2 cents

 

We have done more than 1 of these supercharger conversions. We have also performed them on many other 1999 cars that are running fine. The rich condition here is most likely due to a boost leak, a bad MAF or a bad vacuum check valve. We do not tune like you mentioned above. The timing maps are very low to preserve the engine longevity. We have spent countless hours tuning part throttle so that these cars can operate like a normal car during day to day driving. Vince and I have been in contact and he is in the process of checking some things on the car.

 

It wasnt intended to rub you wrong however Vince has asked me to look at it more than once but I have been to busy. There are many things that can be wrong I agree. IS there a dyno run available for you to post that shows the correct airfuel ratios so everyone can see that Vinces car is just acting up and that your product is not the one causing the problems with incorrect fueling

 

Not rubbed wrong, just want to get the correct info out there. Vince was going to get his boost gauge hooked up so we can see what boost level it is running and at what RPM.

 

Good becuase I am now very interested in a proper air fuel run if you dont mind posting of course

 

SURE here you go JD

 

Still seems to dip into the high 10's oh well mid range still need some leaning up would help oh power as well especially in the mid range just a thought

 

Have you ever calibrated a Bosch ME5.2 ECU? If you have, have you ever tuned one for a forced induction set up? Becuse there is no boost sensor, you can never get them 100% perfect at all RPMS like you can with a turbo ME7.8 ECU.

 

HAVE YOU? Seems like all the giac distributers call themselves tuners I highly doubt it. I not only do Porsche in every aspect but also tune on Lambo,Ferrari,BMW, Mercedes,Bentley,VW, Audi, Seat,Renault,Smart,RollsRoyce,Lotus,Range Rover, Maserati,MINI, Just to name a few Todd, Now do you want to say that again.

 

Rather than just talking JD, I am sure you have a graph of a tuned 1999 SC'd car that you can show us all that displays what you call proper tuning. Or are you all talk? Seems you are claiming to have tuned every car sold for every possible setup. Wow, you are fantastic.

When you setup a tuned system for general public consumption, you have to use a conservative program that tries to anticipate sall driving conditions as well as provides for the longevity of the engine. In 5 minutes I can lean out my car and greatly increase the power, but at what cost?

When you offer an SC system for a car that has a computer that cannot read boost and provides the absolute optimum fuel ratios at all speeds and driving conditions, maybe you'll earn a little respect here. In the meantime, it is nothing but talk and no one is listening.

 

i'm listening....

 

OK, have you ever tuned this type of ECU with forced induction? My job as a GIAC affiliate is not tune the ECU rather bridge the gap between the car and the Garrett. Our input and our analysis of how the car is operating are then used for him to program it.

 

This will be the last post I do on this thread as its becoming a ball busting session. Yes I have if you look into a company named Turbo Performance Center as in TPC back east I tuned there supercharger setups. I have added the link in case your interested

http://www.turboperformance.com/

its right on the home page matter of fact I will even give the contact person his name is Tom or you might want to speak to the owner who flew me there his name is MIchael levatis you choose Todd

Im done here on this thread becuase of a simple suggestion about leaning up the air fuels a bit you got all bent out of shape. I believe the idea behind forums is the ability to be open minded and able to take a suggestion on how to make products better for the porsche enthusiast out there.

Just for those who are interested I do happen to own one.

I dont know why you think I am busting your ***** and I am not bent out of shape. This thread started going south when you started in about bad tuning on this car. I simply stated that I think that Vince has a problem with the car and possibly there is a boost leak etc. Opinions are great and everyone is entitled to them.

 

I THINK IT'S TIME FOR A SHOOTOUT!LOL
