i have a Question about the H22a1 ecu. i have a 93 prelude and i want to swap the motor into my
89 civic si. i found motor mounts and axles but i dont know what to use for the ecu. my friend told me to
get the obd0 to obd1 conversion harnes and use a chiped p28 ecu, but i was wondering if i could use the
prelude ecu and wiring harmes, or ecu and ob0 to obd1 harnes, to make it cheaper.
any advice would help, i have looked and i dont see anything that aplies to me.Thanks!

 

run the 89 civic harness.

add the wires for the vtec solenoid and knock sensor.

and obd1 jumper harness with a chipped p28 and chrome and ur set

 

there is no real support for the p13 except a couple base map all motor proggies that are alright but if you want to really tune the motor go with the p28

 

^^^what they said

 

cool thanks! ill do that.

 

does your h22 have an external coil? if so, get a jdm dizzy.

 

yeah it does have the ext coil, will it not work if i use this dist?

 

it's just easier to wire up your existing harness to the internal coil dizzy.
you can use the external coil, it's just a bit more wiring.
