E36 m3 auto to manual swap failed smog?

[mr.vang]

Um....yes, you should have done that when you did the swap!

I didn't do the swap. I bought the car already swapped.

Since the car already had a manual s52 dme, maybe I can unplug the automatic transmission computer so the manual s52 dme won't be bother by it and the codes no longer exist. Its worth a try but I'm still waiting to hear from 328ijunkie and the people on m3forum.

On the E46, you can recode the dash, ews, abs etc. with several different programs,
factory or aftermarket. And yes, abs cares for traction control reasons.

If you are properly coded, an e46 manual does not want to see an a/t computer.
I dunno about e36, mine are obd1.

Who's r3v's go to guy for reporgramming modules?

Ping Dave/328ijunkie. I'm sure he'd be able to tell you definitively what the issue and the solution is, and I'm pretty sure he can take care of it.

[george graves]

Tell me about it. If I can't get it sorted, I'll just have to paid $300 every two years to get it smogged.

I was going to say getting the ECU coded would work it out, but maybe it's the cluster reporting it?? I haven't played with the can bus other then a prototype I'm working on, and now this has me all mixed up as well.

Who's r3v's go to guy for reporgramming modules? ETA / Mark D? I know he knows more then I do on the topic.

Pretty sure that won't clear the codes.

Just pull the auto warning bulb from the cluster.

My E39 threw CELs for a failed seal in the torque converter until I had it replaced (not cheap). It would not have passed a TN emissions test.

From all the research I did, at the end of the day it only meant the car was running a couple hundred RPM higher at speed. However, I understand it's a Federal thing - in US spec (OBD2) cars that is an "emissions-related" code, which triggers the dash light and records a stored code. It's also my understanding that same issue does not throw a light or store a code in EU spec cars.

I blame CARB.

I found this to be an issue among others auto to manual swap cars too. Like you said, its a federal thing and CA just took it way too far.

So I pulled the dme and its from a manual s52. Do you think the auto cluster have anything to do with it? I was reading online and others are mentioning about reprogramming the cluster to clear some codes.

I'm talking to a seller on ebay and this is what he said, "Possibly need to recode the EWS module and/or remove the auto computer if it's still in there. Usually ews delete + ews module removal does the trick too."
"Ews module is coded for the trans type. It talks to the ecu and tells it what maps to look at (auto or manual). The manual dmes are usually forced into manual mode so I'm not sure what's missing here. It's more than just an anti theft immobilizer."

From my research last night, others mentioned that the car will not start if the automatic computer is removed/unplugged. What else does the automatic computer control? Some say it has something to do with the asc and cruise control as well.

[mr.vang]

Should not see why that would not work. That is what I was going to suggest.

Apparently, I just double checked and the dme inside my car is from a manual. So, that throws the idea out the door.

Mass has nearly same communist laws when it comes to inspection except when vehicle become 15yrs old you can have a Christmas tree lit up on your dash and your good to go.

We need that here. Its not like we have a lot of people driving 15 years old car around anymore.

Wow - smog failed for a OBC fault with nothing to do with emissions?

A bad gas cap I can understand. But a tranny selector switch? As if the motor is going to put out different emissions where it's in neutral or drive? Ouch.

I bet the selector switch is looking for contact or resistance provided by the gear elector assembly. If you still have it, you could probe the values(assuming it's not just a connection) and fake it. But the ecu might still trow a fit if it thinks it's being started in gear.

I miss so cal. But not this.

This is CA we're talking about. Any faults or anything not certified means automatic fail. Probably the only state where running clean isn't enough.
