Questions about the LT4

**firebirdlt4** · 12-22-2007, 08:11 PM

I put a 96 corvette LT4 motor in my 96 Transam but used the computer off of my LT1 and i was told that i would never get the full performace of the lt4 until i put the lt4 computer in also or used a programmer on my lt1 computer. Anybody got any idea what to do. Any info would be very helpful.

The only difference will be the knock module on your OBDII is more sensitive than the LT4 OBDII, but you can buy the KM for the LT4 and plug it right into your OBDII
