So first of all I have done some searching and can't find the info I need. I am building an old school mini with a '97 B18B. It has a P75 ECU from an A/T. The engine harness is an OBD2 from a GSR (I know it's totally bastardized). My goal is to have a running car without a CEL constantly shining in my face. I would like a functioning CEL though.

Is there a way to remove the EVAP system and fool the ECU into believing it is still there? I don't have to worry about smog on this car, so I would like to eliminate the system altogether (It's a tight fit in the engine compartment already, trying to fit a turbo and topmount IC, no room for an EVAP canister).

I also have to do something with the ELD wire coming from the ECU. I don't have an ELD... From what I have read the ECU will not know voltage to get from the alternator. Is there any way to bypass this? At least fool the ECU to not throw a CEL code for the ELD.

I found a bypass fix for the fuel tank pressure sensor, but if I am going to be throwing constant codes anyway, I don't know if it is worth $4 at radio shack to fix.

If I was able to get a solution to my issues and get rid of the codes I am going to throw I would like to hook up the service check connector, so I am looking for a diagram of the connector. There are only two wires that I am not sure what they do... One is light blue and the other is white/red (I think).

Any help is great appreciated.

just go obd1. it'll be so much easier. 92-93 integra don't use eld. i would find one from that chassis. i believe pr4 obd1 would be it

 

Best person to ask about Honda Mini swaps is Paul Ireson http://www.iresonmotorsports.com/
very smart gut and very nice.. GL with your build.

 

There was a guy in the forced induction section that did what your doing. If you can find him he may help you

 

i would use an obd1 ecu, as it does not look for anything evap system. any of the current tuning systems for that ecu can also disable the eld.

 

Thanks for all of the suggestions guys, sounds like OBD1 is the way to go.
