Re: SCT tuner and knock and pinging
Same problem here with an 03 GT and the AM/Bama SCT3 tuner. Both the performance and Race 91 octane tunes ping on my car which is an auto. Here are the symptoms:
1st gear is fine
2nd is fine
3rd is fine
4th is fine, unless I am just cruising around at say 35-45mph and 1500 or so on the tach. If I just press the gas a little to accelerate, it will ping like crazy however if I press down hard it will downshift and NOT ping.
It will also never ping when accelerating hard.
I have tried different brands of fuel and even went up to 94 Sunoco or 93 Exxon/Mobil with no change.
The 87 tune works fine for me as well.
I'm going to email AM/Bama and see but in the mean time, I looked at the adjustments to the tune and see some timing related stuff . Things like 1500rpm/2000/rpm etc and -1, -2 ,-3 etc.
I'm assuming this is DECREASING the timing?
Also, how can I tell what the default settings are with these tunes?
TIA for any help!
