gmrulz4u Posted October 10, 2003 Report Posted October 10, 2003 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!

Whiskey River Posted October 10, 2003 Report Posted October 10, 2003 Go to http://www.gmpcm.com and look through the downloads. If you have your ECM Service Code then it should be cut and dry. Quote
gmrulz4u Posted October 10, 2003 Author Report Posted October 10, 2003 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:) Quote
