I'm putting a clipped message below on this. This is what one guy was told
on this. The only problem I see with it is you need the entire donor vehicle
when it is done. You can't just buy the engine, harness, computer as a
package. This is not going to help most people doing a conversion into an
older vehicle. BTB Products wants $245 to reflash the VCM to eliminate the
Passlock, fuel level sensor, add new gearing and tire size etc.
