Obd2 swap?
Does any one know if it is possible to swap a obd2 wiring harness into an obd1 car?

I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant.

Re: Obd2 swap?
Sure.. what generation OBD2 harness.. what application.. what are your goals?? OBD2 Mx3's, Mx6's, KLDE 626's, Ford Probes arent true OBD2... They are a hybrid thats trying to be... You can pull codes threw the OBD2 port but you can't get any kind of data... its very limited... OBD1/OBD2 harness are not completely plug and play though... There are minor differences..sinix3 wrote:Does any one know if it is possible to swap a obd2 wiring harness into an obd1 car?
626 KLG4's are full OBD2... With the right scan tools, you can pull codes, have access to full OEM style data logging/diagnostics.. Bidirectional controls ect...
I don't know about the millenias since I haven't played with any of them..

Re: Obd2 swap?
I think if your not interested in the trouble aftermarket FCU's can create using an OBD2 harness and ECM is a smart choice. I found the OBD2 ECM corrected the rich fuel condition that plagues the KLZE in our cars. The 220cc injectors in the ZE can deliver almost 22% more fuel than the K8s 180cc ones. While monitoring the system I was seeing up to 20% fuel correction by the ECM in my OBD2 system. I had no problem with a rich running engine and I didn't have to deal with after market tuning. I'm not saying aftermarket is bad I mean I'm using an aftermarket fuel map in my subie I'm just saying. The OBD2 system was dependable and trouble free.

Re: Obd2 swap?
OK, from my research of wanting to go OBDII I found that if you are running a ZE it is not worth it. There is no OBDII KLZE ECU only DE ECU's. BUT there is the KLK1 ECU and this is an OBDI/OBDII hybrid so really it is neither. A couple problems with it though, first it is Japan only, 2nd it uses a hybrid wire harness that has OBDI plugs as well as OBDII plugs so you have to have an engine bay wire harness. Lastly no one knows what MAF/or VAF is supposed to be coupled with it. I found one importer that advertised this ecu with harness on a ZE but did not have the MAF/VAF to go along with it. From all the gurus I talked to no one in the states has successfully gotten this ecu to work.
If you were going to do a KLG4 or KLDE swap I would say do it, there is a guy on MX6 club that makes a OBDI to OBDII adapter harness that is plug and play for 100 bucks with a diag port (which really was the only reason I wanted OBDII).

Re: Obd2 swap?
ok well the reason i was thinking about an obd2 swap was because i have a check engine light on all the time but it wasnt before i swapped the computer but when i went to scan it i got no comunication so i did the paper clip trick and its throwing a s--- load of codes so my thought is i have a pooched ecu but i had an idea.. are the ecu wirings the same between a 92 mx3 and a 93 mx6?
92 mx3 gs klze swap.

Re: Obd2 swap?
don't get to caught up in the codes... You can set MAF and O2 codes for a few different reasons that aren't related to the actual sensors...
