OK, I have managed to fry two Honda CRX ECU's this season. First one was a 90 modified JE Import unit and second was a stock 90 ECU.

After the first one, figured it might just be the ECU chip. JE located the chip into another ECU and it was fine.

After the second ECU was fried this year, I am thinking it might be something in the car.

Basically, the ECU give a red light on all the time error code. When you look in the manual, Honda says if the red light is on all the time, replace ECU.

When this happens, the car struggles to run over 2500 rpm or under load.

So, any suggestions of items to check. I really don't want to put another ECU in without looking for something. $100 for an ECU and a trip to the paddock during a race really sucks!
