The Manual Trans PCM has dual rev-limiters also, one for first gear and another for the rest.
no, it doesnt. there's no way for the ecm to know what gear it's in with a manual trans as there's no sensor for that, so it only uses the first rev limiter table.
How many times is too much for re-flashing the PCM? I've done mine maybe 20 times in the last month. Is that bad?
nobody knows the answer to that, i've flashed over 200 bins to mine and it's still ok.
I've finally adjusted my MAF calibration, I brought the lower hertz down about 7-3% and the upper ones up about 4-9% that helped a ton!
yep, that's about typical for modified intake tract and a cam!
I have noticed appreciable driveability and torque under the curve by messing with the two O2 settings you listed on your how to website for LT1 PCM tuning. Even the tone of the exhaust sounds meatier with adjusting those delays.
can you provide any details on what you adjusted and how much?
I do still have the BLM slpit issue (decent size cam). I need to get a thermometer and check each cylinder for temp and trim each cylinder.
what are your iac counts, what throttle body are you using, and how much have you enlarged the idle passage?
I can get you data logs and a copy of the respective tune so you can see what I have done so far and the effects it's had.
cool, please do!
