Hondata 4 Bar Map Sensor Issue
 

Ive been building a Full Blown turbo kit for about the last month. Yesterday, i dropped off my car with my tuner to be tuned today. So I got a call this morning from my tuner and he told me that they got my car cranked last night, but there was an issue with my Hondata 4 bar. He said it was reading -5 at idle and suspects there are issues with the wiring to it; that maybe it has the wrong voltage or something. They will not have time to chase it down. I'll have to fix it on my own. The only thing is, I never touched the wiring to it except to unplug the factory map sensor and plug in the new one. I did extend my wiring harness on the passenger side and tucked my fuse box in the fender, but I don't think any of that would be the cause. I could be wrong tho.
I am running a new to me aem 1052u and I did wire in the wide band, boost solenoid and oil temp and pressure sensors. Could any of these wires into the ecu be throwing off the map sensor if they are incorrect (which is possible, but I doubt).
Someone please help prevent me from pulling my hair out.
Thanks.
