That'* why I said that maybe the early model Rivs got the S1, and the S2 came out later that year. Let us know what you find Haro

is that last picture from a weird angle/lens, or is that a GIANT space between the bumper and rad.

There is a good foot between the bumper and radiator, but lets stay on topic

My former boss has a 95 riv with the Gen3 S1. However, I know I've seen S2, but assumed they were 96'*.

Why don't you just change the ratio and shift points via the tuner? Or do you just need to know what they are? If so, email or PM DarthFiero a link to this topic.

Or contact him at www.gmtuners.com (sinister performance).

If anyone has the file, it'* him.

In english:1995 Aurora/Riviera, 4T60E trans, L67 motor, 2.93 ratio (FR2), Federal and California Emmissions Tier 1

Closest thing I have to it in a BIN file is a BKKH (1995 H Body, L67, 2.97 axle)

There'* also some indication of a change in the engine management system. Both of the above use the type "428" PCM, but there is also a broadcast code BRLX..same specs as BKZS but using the type "247" PCM in the '95 Aurora/Riviera platform. Both PCM'* use the same 27512 Eproms within the calibrator. 247'* are used on both L36 and L67 motors, whereas the 428 is only used on the L67.

Yeah, I need to know what they are....so I know what to change them to I'll shoot them some emails tomorrow...right now I am remapping the spark advance vs. rpm vs. load...lots-o-fun

Just those two tables by themselves (low and high octane) were WAY off the mark (I have that BKKH file Curt...and that is what I am using to tune the motor right now )

Oh, and BTW...the trans hit third gear today...didn't like it, but it got there.

Shot an email off to GMTuners this morning. Here'* hoping they can help me out

On another note, I got 2 tables done last night...low and high octance spark advance. Maps look way different than the S2 maps did.
