I have a 1995 lt1 with a code 41, anybody dealt with that before ?

 

DTC 41 = Ignition Control (IC) circuit (open circuit)

Could be the white wire from the PCM to the IC module, the 12V power from the coil connector to the IC module, a faulty IC module. Use Shoebox's IC module test procedure:

The engine has just been rebuilt and everything checks out ok except the pesky code 41. My question is can the code 41 be disengaged as to be able to get a custum tune in the car?

 

The code prevent you from programming the PCM? I never dealt with that particular code, but it seems odd that it keeps you from uploading a program. Please elaborate.

I took the car to Ed Wright Fast Chip in Tulsa and we worked on the code,chased it down to a voltage drop but ran out of time and couldn't go any futher until I fixed the bad wire! Now I got this bdas car that I can't get turned cause of a slight voltage drop! It isn't causing any malfuntions in anyway! just causing that pesky code 41 to pop off. Ed has since retired !!!!!! And in Okla city area I don;t know of anybody that is close to his skill level, wa, wa, SO my question is can I take the car to someone and get it tuned with the code 41 displaying?:

 

I never heard of a code that would prevent you from reprogramming. If that is what you are asking. One thing Ed Wright was famous for though was locking tunes. I hear he quit doing that at some point but I have seen some of his that were locked. If your's won't reprogram that is probably why.
