When my '95 Z28 M6 was on the dyno, the shop what was tuning the car fried the computer. I told them to transfer the LT4 knock module to the replacement PCM.

My car has not been running right since then... cam, heads, 383... 11.1:1 CR

How can I tell visually if the knock module is stock or they in fact did swap the LT4 knock module?

Is there an LT4 identifier on the knock module?

For some reason... I don't think they did.

 

Pull the cover write the part number on the module down and google it.

 

after they put the other computer in did they reflash the right tune in to it??? I always reread the tune to make sure the tune trasnfered right....

 

So simple it makes sense. I will check this weekend.

 

I didn't check the reflash since I'm just starting using freescan. The owner stated that the prior program was flashed in the computer.

I can't check the number on the KM4 plug-in that's in my car now but the stock LT1 part I replaced has the following numbers on it:
16177700
1054341

 

 

Awesome! Thanks.

 

Thanks. Checked today. LT4 Knock Module is in.
