Hey guys i was wondering if you could enlighten me on the ecu numbers. I have searched but many post contradict one another

For now this is what I know:

L= California or higher emissions ecu
A= General US ecu
N= Japan ecu

From what I have seen and deduced

L10 is the original 93 h23 ECU
L11 is the 94 h22 ECU
L12 is the 95 ecu

is this true cause i have a 95 accord and i need a 93-95 obd1 us/cali spec ecu to get BAR certified without converting to obdII and getting a much harder to find h22 engine.

to summarize:

Is the p13-L12 an obdI 93-95ecu or a 96 obdIIa? Thanks please help

 

well yea i guess that makes sense since the later preludes 97+ are a different ecu number right?

but i know the 96 still uses a p13 as well.

well i guess ill just get it and test lol. If anyone know what the

p13-L12 comes from exactly that would help a lot though thanks!

you can look up part numbers there..
that is a 93-95 cali p13
it is a diff part number than 93-95 non cali ecus and then the 96 ecus are different as well htough i think all obd2 are 50 state ecus for ludes.

 

^ thanks man that helps a lot

 

i am retarded and cant find under what category to look for the main engine ECU

Is it the one under control unit (under electrical) or engine compartment control unit or even interior cabin control unit (cause the ecu was located inside the car)?

which would it be thanks!
