i swapped a 94 jdm gsr motor into my 92 gsr and used the old wiring harness but new ecu. i am getting a check engine light for the knock sensor and electronic load detector. there is not an eld on a 92 gsr. can anyone point me in the right direction to getting rid of these lights? (when the engine light comes on i lose 40-50 horsepower, happened on the dyno.)

 

I thought 92 GSR engines came with Knock Sensors.... if not, you just need to plug in a Knock Sensor into your motor and plug that wire directly to D3 on your ECU harness at the ECU. I got one from Rywire.

I did the same swap in a 92 LS, the ELD CEL went away with new battery terminals and a new battery, my friend's terminals were corroded.
