ok, so my brother wants me to ask you guys since he is out of town. Does ne body make an OBD2 to OBD1 coversion harness for a 2000 p73 ecu?? or can i just move my seconday o2 sensor farther in the exhaust? and what is the difference between the primary and the seconday o2 sensor? i have an greddy e-manage and if take the seconday o2 sensor out would it go to the pre-set settings if the CEL came on.

 

PM user Kenji...

 

ok i did that

If you want to switch to OBD1 you will need an OBD2b to OBD1 conversion harness and an OBD1 ECU (chipped or stock).

Once you switch to OBD1 you won't need the secondary O2 sensor as the OBD1 ECU does not look for it.

how much would you charge to make a conversion harness for my brother?

 

buy one from skunk2, they arent that expensive.

 

my brother already tried it..they dont fit..we think it might be obd2.1 not obd2..not sure though..the caR is a 2001 ITR

no body knows this? i know they dont make an obd2.1 to obd1 conversion..not even skunk2

 

Just have to look around man. http://www.kingmotorsports.com...t=401

 

ya but is it for a p73..i cant find any..

 

alright, the car is a 2001 right? what ECU are you trying to use? P73? That would not require a jumper.

So far what you have said has made little to no sense, but if you explain exactly what you're trying to do i'd be more than happy to try and help you

 

never mind answerd my own question

 

considering a P73 is an OBDII ecu you will never find a harness for OBDIIb to OBDIIb lol

Time to go back to school

never did i say that

 

can my brother use his emange with this obd2b to obd1 conversion if he has the ignition and the injector harness?? cuz doesnt that take out the A and B plug?

You can't convert to OBD1 if you're using an OBD2 ecu. Whatever ecu you have.....thats what version of on board diagnostics you have. Even if you're only using one o2 sensor, its still obd2.
