hi in goin to do my ls/vtec
but i looked on ebay for the ecu, and i was told that i have to use
the PR3 ecu since my integra is a OBD0.
but on ebay i only found pr3 ecu for b16a1 engine
and my integra is a b18.
comfused
please help

 

B series ECUs are interchangable. PR3s are from b16s. If youre doing an ls/vtec, Id recommend getting a standalone and getting it tuned.

Chip your LS obd0 ecu

 

you can run it with the pr3 ecu it will work fine just connect the vtec and chip and tune i used that ecu in my 90 ls. with a ls/v and a b16a

 

obd0 b16 pr3/pw0 ecu is what you want

unless you plan on swappin over to obd1, which i would recommend

 

what kind of chip and tune

 

just go obd1 and tune it you will be happy

 

how do you go from OBD0 to OBD1 a mean, what do
i have to do
