The chips that plug on the J3 connector have one pin that is dedicated to disabling the internal ROM. If this is nice and secure and has no connection issues and any one of the data bus pins are not making a good connection, then all kinds of weird things could happen.

He has tried two different EEC's which would lead me away from this theory, but what if the Tweecer has a bad solder joint internally. It was used on both EEC's correct? I might have missed it, but did you try a different Tweecer?

Yeah, it's not hard to miss something in this thread....

. . . but yes, we had another brand new TwEECer in stock and I swapped everything including the USB cable, RJ11 cable, and selector switch -- the problem still exists.

How about the 10pin connectors on the back of the intake? Have you dissasembled them and checked for good contact? A lot of people take a pick and tighten up the female side of the connectors so they get better connection with the male side...

I had the SPS apart when I did the head swap, but I didn't look at the contacts. I'll check them when I get a chance.

hey, i would also think about any moving parts... mechanically... like in the suspension... maybe check any wiring that gets near the suspension/ STEERING systems... ans they might have rubbed a wire... and its grounding out... or maybe im stupid...
