The previous owner converted the harness from MAF to MAP. I want to convert it back, but I can not find any wiring diagrams or anything for this. I have a WC ECU with a S14 SR20DET black notch top, if someone could help me out I am willing to pay.

Also could this cause my car to not boost? Basically my bov is not getting enough pressure to release, and the car stops letting me give it gas at 3000rpms, I've installed a new MAF sensor and made sure the wiring was right, but I am unsure if the map wiring could be messing with it.

How can I test the IACV or the Coolant Temp Sensor? Please just help me, I am sorry this is so much in a single thread but thank you. :)

(Additionally please note I do NOT have my exhaust on at the moment since I am waiting on my downpipe)

What did the previous owner do to account for the MAP conversion? Is the ECU stock?

I'm not 100% sure, he had an AEM V2 ECU installed I know that. He has the wires marked. Here is another piece of information my coolant gauge on my gauge cluster isn't reading anything could this be a faulty sensor causing the issue? If so where would I find it on my motor, I found it on the s13 but am not sure on the s14.

Additionally I have the Stock Black Letter WC ECU.
