Any other recommendation where or how i could get a engine runnig signal?
GND or +12V
For me it seems like that the nitrous output could be configured to only have grounded when engine running.

The new ecu is ordered but need a solution in the mean time.

What about nitrous output? Could use that for fuelpump and prime the pump with a button and second relasis?
Only need a solution for a few weeks.

Software 4.2.5.0

Serial over 4000 dont have ecu here and no internet in garage.Must note per hand next time im threre if nessesary

Get most solved.After erasing ecu and download a fresh cal the sensordata is there and the engine starts. :-)

Measured the e1 and e7 against ground when running and ...

So maybe the outputs on my ecu are burned.
I tried it but the mainRelay did not switch.
So i rewired the relais do ignition and let the E1 and E7 unused.
The software than shows Ignition on and i clould upload the eu-civic-pra cal with immobilizer disabled.
But al sensor data i see is not right ...

Acording the hondata wiring diagram the E1(FPR) and E7(MainRelay) both switch the ground side of the coil.
Yet i have found a Honda Pinout for the E Plug and this reads to me that E1 swicht GND and E7 +12V to the coil.

With ignition switch ON ...
