Hi Jeff ,
I removed the cover from the replacement unit and the
Mass Flo unit. I removed the j3 chip from the Mass Flo an plugged
it into the new EEC unit. The J3 chip has all the programmed
Info in it. The chip in the EEC is not programmable but because it has
a J3 slot you can attach another chip onto this that by passes
The original chip. So to answer your question Mass Flo programs
their own chips then plugs it onto a rebuilt unit. They also put on a different
case cover so it can be universally mounted.
Have ever called them for any support? Can you tell me if you ever got
a reply from them? The only time they ever returned my call was when I was
Looking to buy. Now I get nothing.
I still have the a/c problem but the car does run good. I'm going to have a friend make a new harness. I think I have a polarity problem
