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!!!

did you check continuity all the way to the ECU? how about power, are you getting 5v at the connector?

you might already have this shit, but here it is anyway:
Pink: +5V power > MAF pin 1 (green/yellow)
Gray: Signal > MAF pin 2 (orange)
White: Ground > ECU sensor ground / MAF pin 5 (black)
 
No sir! i didn't test it that way before! But i just did a couple minutes ago! and yes all three wires have continuity ,And the pink or purple on my harness i'm getting 4.99 volts and 5.04 volts while the engine is running!
