Stats of my car:

-JDM H22
-P13 ECU (Stock) OBD1 connected with a Piggy Back Harness
-So that's OBD 2 converted to OBD1 in simple words
-Field AFC/VTEC Controller (Map sensor currently disconnected)

Maryland emission Law:
97+ years with ODB 2 connections are connected to a diagnostic machine to tell what's wrong with the car. It check for Tampering with ODB plug, CEL Light, and ODB communications.

Where I failed:
My car failed on OBD 2 communications (I am assuming this because of my swap converting the OBD 2 to OBD 1 for the ECU) Basically the computer is trying access an OBD1 ECU and it's failing because the OBD 1 ecu was not made for that type of diagnostics.

Has anyone had this problem? If so, do you know of a way to wire up the OBD 1 ECU to communicate with the OBD 2 adapter/diagnostic machine? I honestly think I am assed out but I was thinking I could purchase a used OBD 2 ecu and connect it to see if that works, but I doubt it because that motor wired up OBD 1.

dont know any mechanics to hook you up?

Shady stickers ftw

I love shady stickers

The friendly mechanic...
Set up a test ecu and provide it with the proper voltage returns on all of the sensor and servo leads. Then connect it to the primary OBII port so that when they plug in they get the readings. You could place the appropriate sensors into the electrical harness to provide the dummy ecu with data for the emissions tester's diagnostic tool. The only thing is... you have to know the correct voltages so the ecu doesn't fail or through codes.

Good luck.

LOL WOW, I thought of something that extreme but DAYUMMMM cats have done that hahahah Man if it fails and I know it will never pass again, I'll strip that some of a biotch and put it on the track and road race with it!!! F)#@$*( THAT

I know that in WA, if you spend over $150 to get it fixed you can take it back for a retest and if it still fails than you show them the receipt and they will pass you cuz you did attempt to fix it.

Sweet, I am hoping thats how it is here they just charge 300 more LOL, but I'll try my OBD 2 ecu out and if that doesn't work I might have this dude try and write me a el-faky receipt that pose a fix. I should just tell em look, I have a different motor and its fine suck on these and pass my ish>> hahahaha lol

Im sorry for calling you stupid but you are. Im assuming you dropped a H22 in your car because you like modifying your car. You liked the motor and put it in. You did a performance upgrade. Such a big one where i would assume you know what you are doing and talking about. By all means. When you buy a OBDII to OBDI conversion harness doesnt mean that you will still run OBDII. You know that little plugin under your ashtray? Thats OBDII only. Therefore 96+ cars get hooked up to a scanner for emissions testing. Story made simple you need to find someone who can pass your car with someone elses vehicle. Goodluck and be careful.

btw it shouldnt cost more then $80

MD sucks - state controlled at state run centers, its hard to find a friendly mechanic.

ajtcl sounds like you've done this before a few times.

97CLgenius

no doubt tell me about it, its all good though, I'll figure out something

I've done similar setups with computers (unrelated to cars). Using "simulators" is common when trying to diagnose computer issues. It can be usefull to provide false inputs to a computer to determine what it is doing in real time operation. Flight avionics are tested this way all the time.

Good luck.
