WMI on AUX1 not working

Post by vti906 »

I will try to use aux1 as an output to control the relay to start the WMI pump.
I don't understand why it is not possible to define tps and vss conditions, but despite the fact that according to the logs all conditions were met, the N1On light did not light up and thus the output was not activated either.
Am I doing something wrong?

Post the calibration and a datalog showing the issue made using it.

What is the part number of the ECU you are using?

it's EUDM P28 ECU, but what does ECU HW have to do with the fact that the software did not evaluate the correct conditions?
the output test itself works without problems.

Your ECU does not have the circuitry for that output to work.

What are you talking about ?
ECU is fine, I'ts modified to IAB switching circuit and as I wrote, it's working.
When I test output via online/test output menu, I'ts working without problems.
I used this output until now on a stock GSR intake (with working IAB) without problems.
The question is why the N1On does not turn on, not the hardware circuit.

I had no way of knowing that as you did not say that you had added that circuitry.

Your load conditions are not being met according to the datalog.

that's why I wrote that the output works...
minimum load condition is set to 900kPa, that was set by default in Smanager...
that's the problem, it must be set to 900mBar :-)
thanks for hint.
