2 bar map from hhp issues

I purchased a 2 bar map part #050332224ab for my 2007, when i plug it in i immediately get a low baro cel and the tps red lightning bolt, the instant i unplug it both issues go away, this happens with either 1 bar or 2 bar tune from diablotoona so my first assumption is a pinout issue as the connectors are 180° different as far as the alignment ridge, has anyone had this issue? The part number crosses to a 2014 ish dodge but is the pinout different on a 2007 jeep?
Thanks for your help guys!

No backstory just have been on the forum and have seen continuous issues with his tuning.

Had this exact same issue with Johan tuning my buddies whipple Durango. Ended up using the stock sensor but now the engine is built and we are about to fire it up. He blamed it on diablo T1000 not playing nice. Now have tune loaded with T2 module but waiting on some fuel fittings to find out if issue will be resolved. Guessing it’s not the SW being your having same problem with HP

Map reading is 25 inhg spot on but baro reading is 32 inhg,
I'm hoping that the cmr program allows to custom scaling to get baro to 25 inhg, i know i can do it with my diesel tuning software so i don't think there would be an issue with cmr software allowing it as well, just for reference my digital barometer shows 24.48 inhg.

Do you know if cmr software allows separate baro scaling?

We were seeing both MAP and Baro readings maxed out to like negative 99 or something so problem may be a little different.

I imagine CMR allows for scaling like the HP tuners I’m used to. But it’s probably much more complicated
