One of the challenges I see with the 96 LT1 vs. 2002 Express Van '0411 L31 are the spark tables. The 96 LT1 uses MAP Sensor tables for spark advance and the 2002 Express Van '0411 L31 uses MAF Sensor tables for spark advance.

The 2002 Express Van L31 Injectors are Sequential Fire.

Seems likely the LT1 would benefit using the 2002 Express Van '0411 MAF Sensor?

Seems likely the LT1 would benefit using the 2002 Express Van '0411 Ignition Module?

Seems likely the 2002 Express Van .bin file would require a VATS delete and possibly some Emission deletes also.
Correct, when this conversion is done it runs in batch fire mode. I can turn off VATS and any unneeded codes. As far as the MAF I can swap if needed, but I have to see if that is needed or not, same with the ICM. The 2001 express van tune has also been used, not sure if that is different than the 2002.
