well i currently have a 92 ls and im gonna be swapping in a gsr motor soon... anyways i got a bod1 gsr ecu and i plugged it into my car today to make sure it works and i got a few CELs...one was code 9 which is the distributor, 21 for vtec and code 20...from what i've read its a problem with a censor or something...does anybody know what would cause the code 20???
i was thinking maybe a knock sensor???

another wierd thing is when i plug my stock ecu back in, i have no CELs at all...and i used to have a p28 and only got a CEl for the vtec when i had that...
im not really sure why im getting the code9... im actually using my gsr distributor on my ls motor cuz my stock distributor is screwd up but i would figure if that was a problem i would ge the cel with my stock ecu.

anyone have any ideas for me?

code 20 is the electrical load detector.
