Contour Enthusiasts Group Archives Forums Modifications Forced Induction TIME to Tune the turbo mystique

I drove 20hrs to get my car tuned and the engine blew on the dyno so 6hrs sounds like a breeze.

I'm leary about mail order chips, even from SCT, if anything is messed up with the tune things can go real wrong, real quick. When I finally got back from ADC and installed another engine and got the final program we tuned, the car didn't run, wouldn't even start. Took three mail backs to finally get the right program on the chip. They burned the wrong binary a few times and if I wasn't super alert checking my timing with the OBDII scanner the engine would have blown again.

Make sure you tell SCT everything you have on the engine, especially the MAF. That's where ADC had a hard time doing my car. Personally I think that MAF you have is too big. A standard Mustang GT MAF would be better. Let them know off what kind of vehicle you got it from and what size your injectors are and all that good stuff.

When you finally do get the chip with program installed, check your timing with a OBDII scanner. In 3rd gear flooring it under boost, your timing should be around 7-10* advanced at 3000rpms going up to 15-19* by the redline. May seem low, but one Focus guy is running 12psi and 6* advanced at 3000rpms. Make sure your midrange timing is good and that your tip in throttle fuel and timing response is quick and your cruise timing is stock and you're good to go. But that is the hard part.
