Ok, Swapped a OBD1 B16 from HMotors into my '93 Del Sol, Wired up everything correctly and went to drive the car. Car had no power, runs rough under 3k rpm and has no throttle response.

Put in a P28 ECU and car Ran perfectly, great performance, ran like it should.

Parked car overnight and ran exactely like it did with Bad ECU, same symptoms. No CELs or anything.

Put P28 in another car and it ran like crap in it too.

Just put in a DX ECU to see what would happen, ran great, of course no Vtec.

Parked it overnight again and same results, burned out ECU. Throwing ECU Code 16.

Not sure what is going on, I have burned up 3 ECUs now and can't afford to keep doing this.

Has anyone ever encountered this before? ECU's appear to be in good physical shape, no burned pathways, no scorch marks, nothing, everything is visually ok, but the ECUs are screwed.

Any Ideas????

 

#3 injector was grounding out due to my shity soldering so the injector was not fireing,fix that and put a new dx ecu in it, now it runs fine.

so would the injector grounding out kill the ecu?
