Ok, i have the conversion harness, gonna get a chipped p28, do I need anything else? I heard some kind of transmission thing thats underneath the steering wheel since I have auto trans.

 

I've done auto's connverted to OBD1. Shoudn't have problem. Power loss through the tranny ofcourse.

 

so just the p28 and the harness and i should be gravy?

 

you need more than OBD1 harness and ecu for to convert it to OBD1

 

WALTER! long time, no talk! whats up man? so what else do i need?

 

What car, what motor?

 

1999 civic ex, d16y8 auto

 

Haha...have fun. D-Series AUTO FTL!

Didnt you try this once already?

I believe you need a custom step down harness so that you can retain the factory OBD2 Auto TCU (do Auto D-Series OBD2 have external TCU?) and run an auto OBD1 ECU.

Most likely your best bet is to chip an AUTO P75 ECU and convert it to VTEC as well, run it with your custom harness and stock TCU.

Might work...has for the B-Series

 

buy a new car

 

the whole point is to boost this pos civic and sell it, to make a nice downpayment on an s2k... :P
