I'm trying to identify an ECM that I purchased with a complete TPI, the seller had it on a 79 z28 w/350. He stated it was an '89 TPI and was reprogrammed to work with his mods headers w'duals, 52mm BBK tb, 24lbs injectors w/46lbs of pressure and a nice cam. The plenum is a '89 and unknown about the rest. I just wanted the BBK for my '90 IROC w/5.7.
The compuer ECC number is 7-7730, calibration code 0202AR and the memcal says Kipp dated 3/23/01 PO4802.

After some research I figured out it is a computer from 90-92. The prom in the memcal is solid white with no writing on it.

Any info would help
Thanks,
Tim
