ECU Swap Question
I have a 85 with a 383. I want to swap the 870ecu for a 1994-95 16188051 ecu. The 870 ecu is still in use for the car's dash cluster. I was able to pick up a 165 wire harness for a good price with the intent to do a 870 to 165 swap. My Question is can I repin a 165 wire harness for a 1994-95 16188051 ecu? Or will I need a complete 16188051 engine wire harness with ecu? I understand this is a speed density ecu. My car is already running on a after market SD system that I'm not happy with. I want to upgrade to a flash ecu for tuning purpose and to run a 4l80e tranny.

The ECM connectors are completely different (4 vs. 2), so you would need to figure that out.
You can get flash capability with the 1227165 ECM by using a Moates Ostrich or similar adapter.

The later cars have more O2 sensors than the single one the 1227165 ECM uses. You would have to deal with those somehow.
