Anyone have...

I am looking for a stock Spark Table for the 2.8/3.1 engines.

 

Does anyone know where to find one?

 

It's basically is just a Table that has MAP as the "x" axis and RPM as the "y", and then the corresponding Spark Advance/Timing.

 

The PROMs are programmed with this data from the factory...

 

THANKS!:)

Thanks man!:)

 

That site has me totally confused though...I don't really know WHAT to do...

 

I know that the 2.8/3.1's use the ECM #1227727, and I think I found that in their list of binary files, here:

 

http://www.gmpcm.com/pafiledb.php?action=category&id=66

 

But it only lists 2.8's for 1988. I assume 1989 is the same?

 

Also, do I need a special program to read these .bin files or something?

 

THANKS AGAIN:)

You'll have to install GMPCM, the bin file that closely relates to the 3.1L is 88$.
