engine managment trouble

[wallstar2]

hey guys im having some major problems with an engine swap gone wrong can anyone tell me if an a20a injected engines ecu and etc is compatable with and b20a?

if not does anyone know oh a way to get around the problem?

cheers wallstar2

a20a is a single overhead cam
and
b20 is duel overhead cam

[ACTI0NMAN-1]

ecus are not compatable

a little stuffed here in the wiring side!

b series to b series looms eg. obd1 to obd2 are easy to find off the shelf. But for your swap ytou would need something custom. I can only suggest finding an engine loom and ecu from a b20. Even if it means you have to swap out for a new cluster as that way should be cheaper than having an auto elect to the re-wiring for you.

simply not compatible

the A20AX use a vac advanced dizzy where the B20 uses non vac advanced dizzy, thearfor the ecu controls the timing advance.

pin orientaton on the ecu is different as well.

good luck
