I ran into an issue This week and have not resolved it, so I thought I would put it up for discussion.
The problem is this 2002 Ford Lightning cannot pass the IEPA emissions test because all OBD2 Readiness monitors are not supported and IEPA rejects it.

Funny thing. IDS also show the monitors are unsupported but are evaluated (YES):

I had a conversation with the previous shop who tried to get this customer a waiver and also heard from the other shop, that the Ford dealer was unable to program the PCM and it is now an obsolete part. I hesitated but took the job in since we were recommended as a shop that can fix these issues by the IEPA. The IEPA will not give a waiver based on the fact that this is probably a tuner calibration, or at least, a programming issue.
I am absolutely sure this is an aftermarket "tuner calibration" in the PCM, but I have always been able to overwrite any Ford calibration with either the standard reprogramming or a PMI (Programmable Module Installation).
I am using IDS/VCM. I am update to version 97.3 of IDS. The problem I am encountering is that I get a message from IDS that it cannot reprogram the PCM because it is MPC-206 and should be MFC-422A

AS it turns out, the hardware is correct for this lightning:

I called the local Ford parts Dept. and indeed the PCM is obsolete. I asked them for the correct part # and it was given to me as engineering #2L3A-12A650-ABC.
I exposed the PCM under the right side dash and it has a visible tear tag with 2L3A-ABC (tear tags skip the 12A650 since everyone can see it is a PCM) , with a "catchword" code ABU2. These numbers are identical.
According to IDS, PCM Part # is 4C3AA LA. The file name is TALD 3F3.
The IDS offered update # is 4C3A-12A650-ALC which must be legit, it got current calibration info from the PCM, right?

My question is, what is the workaround? This is frustrating because PCM tear tag matches the factory part #.
