'87 Prelude

[88WhiteLX-i]

My friend has an '87 prelude with the same engine as me 2.0 efi. and after a while of driving his PGM-FI light comes on... Now I know that you can read the led on the ECU.. Iam just not sure where the hell it is.. If anyone knows where it is I'd appreciate it alot, thanks

Looking from the back, under the driver's seat, there's a box. If you flash a light underneath, you'll see a tab which you can pop off to expose the LED. Count how many time's it's flashing to get the code.

Alright once I get the ECU code where can I find out what it means? Has someone already posted the codes and what they mean? Or where would I get the codes from? Thanks guys

On the Prelude, the ECU is located to the rear of the driver's door. remove the rear driver's side ashtray, and there's your LED.

See if he will let you try his ECU while you are at it.
