93 lt1 speed density vs. 90-92speed density
Hey, i'm new to the forum and have been looking around the site and the internet for the difference between the two systems.
So far i know the 93 lt1 still uses the non-electronic trans like the third gen and it has the removable eprom.
Are the wiring harnesses the same...or close?
Are the computers in each system the same?
Will the computer from a 93 hook up to the 90-92 speed density harness...and vise verse?
Thanks, i havent been able to find a direct comparison between the two speed density systems.

Car: 1987 GTA
Engine: LT1
Transmission: T56
Axle/Gears: 9 bolt 3.70 posi
The two are totally different. Wiring harness is different, PCM has 4 connectors on it, plugs are in different locations, LT1 has the distributor in the front, coil is mounted on the driver side head in the front.
Two completely different beasts, one is a Gen1 smallblock and the LT1 is a Gen2 smallblock. Basically the same comparison between the LT1 and LS1
