Easiest way to read boost?

[engineermike]

You can buy a GM 3 bar MAP sensor and wire it to your existing IMRC connectors if you have deleted them. I am logging boost and fuel pressure through the IMRC pigtails.

Does the imrc pigtail have 5v, ground, and the feedback signal all in the same plug? Do you have a wiring diagram for this?

yes it does. There should be a white, black and red wire. red is 5V, Black is signal and white is ground. You can validate this with a multimeter. You will need to have the senor turned on in your tune as well.

@kcc0521 imrc position doesn’t appear to be in my available pid list using a Whipple strategy. What strategy do you run?
