Explorer swapped ECU / Smog question

[zx1206]

I picked up a '99 4WD Ranger that already has a '97 Explorer V8 swap.

I'm concerned about getting it inspected here in Pennsylvania, especially since it has an older ECU than the body.

Is the '99 Explorer ECU interchangeable with the '97 harness?

Pa also has some rule where the car's VIN needs to match the ECU's VIN.
Can I buy a new Explorer ECU and have the Ranger's VIN written on it electronically?

If not can a Ranger ECU control a V8?

How is everyone else in Pa getting inspected?

No. However, you could use the 99~2001 5.0 PCM if you also swap in a bunch of 99~01 parts including:

Engine harness
Trans harness
Transmission (or possibly just the Transmission Range Sensor)
Injectors
Cam position sensor/Synchronizer
Fuel rails w/pulse damper
Fuel pump/fuel pressure regulator

Pa also has some rule where the car's VIN needs to match the ECU's VIN.

Some earlier Ranger/Explorer PCMs do not have VIN info recorded in memory. You'd have to check into it to see if that applies to your situation.

Actually, I don't see how this rule could apply to any vehicle with a non-production engine/PCM swap. Wouldn't you always have a VIN difference in any PCM where it's recorded?

If not can a Ranger ECU control a V8?

No, not anything that you could use with these years.
