EK K swap ecu reads -29 psi

hello forum,
new to the k swap game, I've been having issues with my ECU (possibly) not reading map sensor voltage.
set up:
k24a2
06 si transmission
ry wire harness
runnig on kpro v4

Back probing ecu connector A19 (map) reads 2.9v with ig on. swap map sensor with new one same issue, i can confirm that plumbing for map is correct and the car wont start with the sensor unplugged (so i know it reads something to turn on) i do not have another ecu to test or swap to try to replicate.

The vehicle must be running to correctly read the MAP sensor.

Those are the values when vehicle is running, car runs leans

Post the calibration and a datalog showing the issue.

sorry if i replied late i wasn't able to get access to my vehicle until today, correct me if i did not send it correctly but i believe i sent you my current calibration with a data log.

When running the engine pulls vacuum and this looks pretty normal.

The a fuel ratios are normal? I thought I was reading a lean number around 10-11:1 and if I rev it cuts out and I do believe I have lean protection on (not sure if that the result of that )

10 is rich and 20 is lean. I think you have it backwards
