can the ECU somehow be configured to use a different input pin for the MAP sensor?
Are the calibration settings right for a stock sensor?
My Doctronic ECU can also show raw MAP sensor voltage. What readings do you get?

If it was a 2nd hand ECU, chances are it is damaged.

it happens that the KPro v4 are defective. If the MAP voltage arrives at the ECU connector, but the ECU won't indicate anything, it is defective.

Do you know anyone with a known good Doctronic or KPro ECU. It should start and somehow idle on a suitable basemap that comes with the ECUs.

then don't open the cover, but send it bak to Tegiwa for diagnostics.

Do you know someone with an EP3 Civic or Elise k20 conversion where you might plug in your ECU and see if you get a MAP signal there?

normally you have to open the lid on the ECU in order to access the analog and digital IO lines.
It makes no sense to seal this for warranty purposes.
For a idle and start up test you won't need the wideband.

it should run and idle without lambda signals. Just run it open loop for now.
Would you please check that your TB is completely closed and that your IACV rotor is freely spinning.
