What is the part number that is on the ECU?

What is serial number that is on the K-Pro board inside the ECU?

Without the calibration and a datalog showing the issue it's hard to say what it might be.

More than likely anything that triggers the check engine light would cause it to cut out if that is how you have it set. I do not have a test bench to be able to test this. You can try it and see.

I would recommend that you contact HAmotorsports about this.

For this you really should use an ethanol content sensor.

It is only on for a single frame of the datalog, I would not worry about this.

Im having no start issue stock ecu starts car kpro wont

Start your own thread and give complete details.

I think what you are seeing is slight(miliseconds) hysteresis, of it seeing the values being met to keep nitrous on, then it sees the values drop and it does in fact turn it off.

Who socketed the ECU?

Can you post pictures showing the soldering on the bottom of the ECU?

You can try it, measure the voltage and then test it.

post your calibration as well.

It sounds like the calibration you are using on your vehicle is not ideal. Since Your ECU works on their vehicle and their ECU works on your vehicle.

You will have to try the calibration and datalog and check for knock and make sure the AF is safe. To get the most out of it you will need to get tuned.

Have you tried lowering the timing to see if that reduces the knock?

Either should works as nothing you have done will really change the tuning.
