This page will be devoted to info on the '95 L67 3800SC install into my '87 Fiero. No telling how much detail may wind up here, but it's a start.
For starters, I've downloaded the baseline BIN file for the '95 Riviera, BKZS. It is using a 4t60e trans with 3.29 differential (2.93 Final Drive Ratio). I've also downloaded the other files you will need for TunerproRT ( XDF, ADX)
