i have a 90 civic that i am puttin an ls motor in and i have everything completed except for the distributor and ecu. i want to keep the car obd0 because i already have pr4 ecu. but i am not sure if its from an auto or 5 speed. i am not sure if it makes a difference or not either. the numbers are as follows:
37820-PR4-A02
430-140965 AC
and on the green connector the numbers are 430-140965 OC21

i also want to kno what the advantages and/or disadvantages are for keeping the car obd0 and if i should go obd1. my future plans for the car is to boost it with a mild street tune. any input is appreciated.

 

anyone?????

 

bump. is there a diff between auto and 5spd PR4 ecu's???

 

Auto will run the car.. Search up on how to convert your ecu from auto to manual.

Its simple.

 

i found out that i already have a manual ecu. thanks for the help
