So i've read alot on going from 0bd0 to obd1 and such, im just confused.

So i hear there are like 2 or 3 total harnesses in the car.
I hear a harness from rywire.

So someone please explain what needs to happen in order for me to go to a GSR from my d15b6.

Do i need a harness that goes into my original harness to the new ecu, and the engine harness....i dont even know

 

you need to modify your stock engine harness and chassis harness first from dpfi to mpfi. then you need to modify the engine harness from obd0 to obd1. you will also need an adapter harness that goes from your chassis harness to the ecu.

 

Im not sure what dpfi and mpfi is? is that the injector part? because i have a\ 4 point injectors. and the whole u need to modify from obd0-obd1 didnt really help -.-

 

okay since you already have 4 injectors then that's one step out of the way. and as far as telling you the steps needed, i told you EXACTLY what you needed to modify, the engine harness. i wasn't vague like you insinuated by saying all i said was, "you need to modify from obd0-obd1." I told you you needed to modify the ENGINE HARNESS. if you already knew this, then what is this post about? there are NUMEROUS write-ups not only on this forum, but on the internet as well. a quick google search will give you detailed instructions on how to convert your car from obd0-obd1. I'm not gonna waste my time giving the exact pinouts when it has already been documented plenty of times before. hell, if you had even taken the time to look at the FAQ's in this part of the forum, you would have seen what needs to be done.

 

obd2...why

 

i think he typed the title wrong because in the 1st post he's talking about going from obd0-obd1.

to the OP, here you go. took me all of 2 seconds to get the links on everything you need to do.
