Hello, Ive been servicing this 56 Belair show car with a Ls7 at my work for the last few years. Just wondering if a tune can fix several of the issues Ive been having. It has less than 2000km since being built, was never intended for street driving but the current owner insists on it.
Issue1) P2135 TPS 1-2 Correlation, it sets this code very intermittently maybe once a year, the throttle body has been replaced. The customer just wants it to not limp in when that happens, is there anyway to prevent that from the tune. Im going to try and service the terminal pins with die electric grease but Im running out of options.
Issue2) P0300 random miss, now it wont let me do a crankshaft relearn to solve this because I have P0645 AC clutch relay and P0622 Alternator Field all the time because it has aftermarket AC and a one wire alternator. Im wondering can I prevent those codes from setting in the tune so I can perform the relearn.
Issue3) This one is dumb, the guys that built the car made a custom cold air pipe that is all hand painted to match the engine bay. The dumb thing is they didnt use a silicone hose coupling for the tube to tbody so your going to get false air coming in there. They have these stainless Allen screws that bolt it to the Tbody. Long story Short it sets P0171 and P0174 lean codes. Other than fixing the cold air the only thing I could see is making it run speed density and not looking at the MAF, not sure if that a good idea or not.
The car doesnt have a visable check engine light so Its not like he complains about the codes, the P2135 is what he is feeling so Id like to know if I can tune that out. Thanks for the input.
