Please read completely and carefully:
So, say you want to put an 88 Turbo ECU into your 85 Turbo car. You would need to swap the sensor bung (PITA to remove) and sensor to the zirconium type 17mm units. Then you would have to figure out how to re-wire the oxygen sensor wiring in the harness, because the sensors do NOT use the same wiring. You would be better off finding the correct ECU instead of trying to swap everything else to make O2 feedback work! Now, if this is a race car or you don't care at all about fuel economy then don't bother; just unplug the oxygen sensor and let the car perpetually run in open loop.
