Mike,

Mass Flow Tech support told me that the ECU is pretty much a late 1980's to mid 1990's Ford factory computer. Mine is an older system. They do rechip the factory computer now and can do mine if I like for about $250.

They have been very helpful to me so far and I do not want to bad mouth them. However when I asked what information they needed to do a custom program for my engine they basically said all they needed was the cubic inches, injector size, and the Mass meter along with the ECU. Cam, heads, and compression wasn't needed. I'm sure they know more than me, but it seems to me that they are only going to get the tune in the ball park. So I am looking for someone who can re-chip my ECU and tune it on a dyno. However before I do that I want to get everything working properly, at least to the best of my ability.
