Yeah, the stock SSEi bin file has much more aggressive shift tables than what I was seeing in the other file. The final drive ratio difference probably plays a part in the shifts being off as well. I'm honestly surprised it worked at all...it was one of those "what if" things that looked good on paper.

That little workaround, if it works as well as I hope it does, will open up alot of tuning possibilities. This effectively means that if someone were to replicate this mod, they could do it with ANY PCM that HP Tuners supports, not just the 1997. Which is good, because the 1998-up units are way more tuneable than the 1997 ones.

I was thinking about it, and the closest STOCK tune for my car is going to be the bin file from a 1995 Riviera. It will have ALL the engine tables I need (I still plan on putting the Genny 3 on top if I ever get a hold of a TB), and the correct tables for the trans I currently have.

Now then...who has a 95 Riv memcal I can take to Curt to have it read

I might be able to get the PCM from the 95 Riv parts car I had. When I picked up the car, the guy had parts from it all over his garage. We grabbed everything we saw but I missed the PCM. He might still have it, off to shoot an email to him.

Help me out here and explain to me why the memcal in my 95 L67 wouldn't work?

Gear ratio. Remember...I have the 95 Buick Riv trans, effectively. Different gear ratio (2.93...same as the S2 guys). Shift points in the Riv memcal should be optimized for an S1 L67 and the 2.93 ratio trans.

Your memcal would only benefit me for engine operation parameters.

AFAIK the 95 Riv I had came with a series2 L67 mated to a 4t60e-hd, would that screw up your tables?

No Series II L67 was used in the Riv for 1995 unless maybe it was a swap..

I thought 1995s were the only year with the S1...perhaps it'* the early production Rivs that got that?

EDIT - Found a pic on ebay. That should answer your question Haro.

I understand what everyone thinks is the norm, but when I pulled that series2 out of the 95 Riv, it looked pretty stock to me. I am continuing my research, I will compare the block serial number against the VIN.
