Wow... I mean, F***in WOW!! This has been such a nightmare, but some of it has been self-induced. Let me explain...Winners97TJ wrote: Anyway, I got to trying to reinstall this thing again here is my wiring;
Red - 12V switched power
Black - Ground
Yellow/Black - tapped into Tan/Yellow Tach signal
Green - Sensor side of MAP-to-PCM wire (Green/Red)
Violet - PCM side of MAP-to-PCM Wire (Green/Red)
Red/Black - 5V Sensor power
and what I have found out is that the pressure is stuck at 5.5 constantly. No change at all. Not even if I drop the values in R4.
The reason there was no change in the reading and the check engine light came on when hooked up this way was because when I disconnected the MAP sensor to double check wires... I FORGOT TO PLUG IT BACK IN!!!
(Yeah, I know. What an IDIOT!) It's amazing what happens when there is actually a SIGNAL to modify running down those wires! Thank you everyone who has had a hand in this fun. It is running great, tuning well, and working as it should. FINALLY!
Now if we could only get a version of R4 to work with my laptop and the newer Windows7......
