KPRO V4 Aux for Nitrous Issue

Post by RofromNorCal »

So ive Posted on here in past that had issue with the N20 On 1 was not coming on when it meet it triggers
Ive Depin the Output control from E21, E20, E12 and B6 and found no change Even the Ariming Inputs ive move that from E16, E29, E22 and & B9 the Arming input work fine on the Datalog but Output Control will not Come on.
Ive even Ground out the Output control Pin found Solenoid to come on.

Untill i swap ECU with another know good unit and move from Pin E21 to E20 after swapping the ECU
now my Issue is that both N20 Arm 1 and N20 On 1 will flicker on and off when Engine is Running
But when it Key On Engine Off the N20 Arm 1 and N20 On 1 will stay on with out issue.

My Hunch is that i might have bad Nitrous Solenoid
Since the owner has told me it is used.

Here are some Datalogs that ive made to test the Nitrouse Control
Ive Turn down the Setting Tiggers so i dont have drive it and see the data at Stand still

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

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

From Help, About, what is the version of software you are using?

The datalogs show that it is triggering this properly.

If you connect the solenoid directly to power and ground do you hear it click?
