Has anyone replaced the PCM/ECU in their car? If so, how does one get it programmed to a specific vin number?

Reason I ask is because I swapped a GT500 drivetrain (including electronics) into my 2005 GT. In my area, they recently implemented OBD port emissions testing instead of a tailpipe test, and obviously there's no way I'm going to pass with a vin number that reads differently when plugged into their systems.

How would one go about changing the VIN stored on the PCM/ECU?

 

I just had a manual to auto swap completed, which obviously required a new PCM. From my research, all you need to do is have the PATS system reprogrammed so the keys are tied to the new PCM which can be done at a dealer or any good locksmith. You will need both keys as well to get the completed.

 

I don't think that the dealer can reprogram the pcm so that it showes your vin number. The diagnostic unit IDS/PCM is based on the asbuilt information from the factory,which is based on the original vin. You might want to check with ford racing and see what the procedure they would use to reprogram your pcm.

 

Hi Doogie, the keys weren't a huge issue. Dealer reprogrammed them, and that's that.

My problem is that I need the PCM to reflect the vin number of the car it is presently in, not the donor car.


Thanks, will give them a shot, although I'm admittedly skeptical because the only thing I have from them is a CAI.

 

I might be in the same boat then as I never thought about the vin needing to be tied to the PCM as our emission program uses the OBD as well. I have a year to figure mine out before the next test is due.

 

Have you confirmed they verify the VIN via the PCM? I was under the impression in my state they a just looking for any DTC's.

I did a quick check on our emission process and it states the following:

"The inspector verifies the vehicle identification number (VIN) matches the VIN on the paperwork and then scans the VIN or manually enters data into the Wisconsin Diagnostic Analyzer System (WDAS) to record the vehicle's weight, model year and mileage"

I assume the paperwork is the renwal notice that comes in the mail, but it is hard to tell if this is done visually or via the OBD.

 

Interesting question... we've recently switched to OBD-based emissions testing, so maybe it is that simple. I just can't imagine that we'd roll out something which doesn't test for vin match. It would be so easy to just hook up another car.

 

Does it really matter if there is a VIN discrepancy? Its not the first time an engine has been replaced - whether its an upgrade or a replacement for a blown engine, right?

 

I had my replaced recently at Steeda , give them a call and ask for Matt Levine , he can tell you what is required.

 

Far as I know the ids at a dealership can do it
