Im told the lt4 KM dosent work on 93 lt1s? if so what do i need to do, i have headers n stuff with some false knock! Do i just have mine de-sensitized or whats the deal, not quite sure

any help appreciated! thanks a ton- Mike

 

sorry for such a fast ttt but im allready on the 3rd page hehehe

 

Never heard that before. 93 is an off year for these cars. don't see why an LT-4 KM wouldn't work though.

 

'93 PCMs doesn't have provision for a knock module.

 

As noted above, 93 ECM is completely different than the PCM used in 94 and up. It has a removable chip, and no provision for a knock module. Other means are required to eliminate false knock, and "desensitizing" is one of the options. Procede with care, though.

 

(desensitising) how can this be done, or better yet... who can do this?

 

That's is right.... I forgot the 93's had the chip options, mines a borderline car "94 year". Thought they shared the same PCM. Jet makes does make a performance chips for that year though. Might they have somehting for that issue?

 

i am having ion make me a nice piggy back chip probly but not sure if he can do the desensitising thang
