When I have my foot off of the throttle it's at -14.69 psi and depending on how far I push the throttle it goes up/down.

Does this mean that my map sensor doesn't work? I assume that it should read atmospheric pressure when the engine is off correct?

I'm having troubles starting my car (my base timing won't sync properly, it keeps "walking") so I can't tell you how it acts with the car on.

thx for any help
Did you find out what was wrong? I found that on v1.19 you have to goto Setup -> Sensors-> MAP->options and set "Map Analog Input" to MAP Voltage instead of MAP as Load. Let me know if this helps.
