Changing from OBD2 to OBD1
 

This has prolly been talked about a bigillion times, but I was in the search, but yeah, needle in a hay stack. Anyways, to solve my cat problems and get ready for boost (late winter early spring) i'm going to go OBD1, I was told that would be a better decision and benefit me with FI. ANYWAYS...I know I need an obd2 to obd1 harness and an obd1 ecu (i think it was the EX's before 96?) Is there anything else I need other than that? One of the main reasons i wanna do this is to get rid of my o2 sensor in the cat and just punch that fucker out.

Re:Changing from OBD2 to OBD1
 

i believe thats all you need. and ur 2nd o2 sensor you dont need to get rid of, its jus kinda disabled from the obd1 conversion so go ahead and punch the bitch out... or better yet jus dont run one.

i would buy a pipe er something, but im a cheap ass, so I'm just going to take off the cat and run a crowbar through it, so basically it will be a straight pipe...sorta, but if i decide to get a pipe and dont have an o2 bung, can i just cut off the sensor?

Re:Changing from OBD2 to OBD1
 

Yeah I have doen this conversion and you just unplug the sensor. Come to think of it, I tun closed loop disabled so I don't use the one left either.

Re:Changing from OBD2 to OBD1
 

you can but you don't need to, jus unplug it and let it dangle.

Re:Changing from OBD2 to OBD1
 

you can do whatever you want with it, the ecu won't be looking for it, you can leave it plugged in, unplug it and let the wires hang, leave it plugged in and let it dangle, burn it in or out of the cat, cover it in ---- and leave it on your neighbors porch, whatever you want. the easiest thing to do is nothing at all, and leave it hooked up and plugged in, you don't have to touch it at all if you don't want.

yeah i am doing the same on a 97 LS. Converting over to OBD1 for the Uber ;D

Alls you need is a nice OBD1 ecu and conversion harness.

And that reminds me, i gotta start saving if I want this project done by Spring/Summer :-\

We will see I still need plenty to go. LOL.

Re:Changing from OBD2 to OBD1
 

it's only 200 bucks at the most to convert to obd1, 78 bucks for a conversion harness from jdmshit.com, and 120 bucks for a chipped ecu from me ;)

Re:Changing from OBD2 to OBD1
 

only $59, not a bad price. I went just for shits and giggles comparing brand name stuff, skunk2 wnats $200 for the harness, wtf...but the link csaddict gave me if prolly the one im going to order

Yeah I was saving up for a spoolinperformance mani/dp/dt combo first but we will see. Projekteg do you add datalogging cable, and zif socket? Once I'm done I'm gonna go with Xenocron for some WBO2 street tuning.
