I have a built B18A1 in a 92 Integra GS with a PR4 ECU and a Hondata 3b. The car was running fine for a few days but now it won't start. The LED on the interface box is blinking slowly. I have tried swapping interface boxes and ribbon cables but it is still blinking. After I reset the ECU the LED still blinks slowly. I can get the engine to start but it dies because of the 550cc injectors. The thing is that sometimes the LED stays on and the car runs fine. I did have a CEL code 20 (electronic load detector) when they were installing the Hondata, injectors, relay box, and intank fuel pump. I think I may have a short circuit in my wiring. Thanks in advance for any help.

 

it sounds like either your ROM got corrupted, or something happened to your
ecu where it cant communicate with the box. Contact your dealer/tuner to
have him take a look at it.

 

Thanks sgT. Anyone else have any suggestions?

 

Yep. Do what sgT said.

Unrelated to the main topic, but does anyone know what code 20 (electronic load detector) actually means? I've had it since I first bought my integra. When I swapped the engine into a new body, I continued to get the error, so I'm guessing it's getting it from the alternator.

 

yes, it does come from the alternator, but its not always that. I once solved this problem by replacing the battery
