88 Cutlass Supreme chip

[3100 MPFI]

I'm working on restoring a 1988 Cutlass Supreme International with the 5 speed but I've got a problem with hesitation in the throttle. I seem to remember something about it having to do with the maf sensor.

I pulled my ecm to see which chip I have but I can't seem to find any info on its chip.

The chip in there is AMAR 6996.

Does anyone have any info on this chip?

Its not the latest revision but it was supposed to help with stall after start, decel stall, cold hesitation. The chips that replace the MAF for MAP are ATYZ, ATZA, ATZB, ATZD, ATZF. Fixes throttle tip in hesitation stall.
