i'm wondering which would be better for performance on a turbo zc motor ....would the 88-91 si ecu be better or the 88-89 teg ecu be better......i'm just wondering if any of you guys have played around with this or not...i'm about to switch them around and see for myself

 

The motor runs much smoother with the integra ECU (I have one). It runs it a bit rich.

Drivability sucks with the Si ecu.
