Alright tuners! I'm in need of help on this: After i installed and set everything for the speed density! using ecmlink plug and play harness, My omni 4 bar is not reading any vacuum/boost! Engine starts and even runs fine, It's just that i can't get any vacuum/boost from the sensor. Any one here has this problem before?
Here's a screenshot of the setting...

previously: I was running the same sensor on the factory MDP pin(the green plug) and it has been working fine no single issue.
Now if i unplug the ecmlink harness and put back the green plug also needs set back the assignment pin from baro to MDP and it reads vacuum/boost again!

Seems like the ecmlink harness it's fine because if i unplug it while the engine is running. It shuts off instantly ,Also I tested the continuity on all three wires and they are all good
am i missing something else on the settings? I'd like to get some inputs of you guys!
Thanks in advance!!!
