HOW DO YOU DYNO TUNE AFTER MODS
Ijust picked my car up after all the boltons last week. At carlsbad yesterday it was pinging REAL LOUD. Tight befor I shifted into third at 4800 rpms the car would hesitate and loose power and then come back on at around 5200 rpms before the shift. Something definetly does not feel right here. The cars computer was custom made for my exact mods to. Can anyone tell me what they do to tune the car for optimum effiecency and where in orange county it can be done.
Thanks :cheers: :confused:

Check out any software Ease or similar and a MAFT
I have a spare MAFT I am not using, but it helps to use the scanner software to see things you would otherwise guess at. Pinging at WOT is a definite no no and I would know as it cost me an engine 2 years ago.

You didn't give us any information about your car or the mods. Sounds like your custom program is fouled up - too much advance on the timing. Speed-Racer is right, you don't want to run it that way. Most cars will run fine with the factory program even with a heads/cam package. Until you find a place to dyno-tune I'd get the factory program re-installed.

I wont touch the car myself. I guess I will have to find a shop to dyno tune it. If I can find this shop, how exactly would they tune it, what procedures do they use? :cheers:

The tuner will plug a lap top computer loaded with a program like LS1edit into your PCM. They should install a bung in one of your exhaust banks up stream of the cats to accurately measure air/fuel ratios. Using the lap top they can adjust A/F ratios, timing and other parameters and verify performance gains using the dyno. Dyno tuning by a reputable tuner is not cheap but the best way to go.
