I have a Generic Output/Always On E21 control using certain conditions to activate a 2nd fuel pump.



In Kmanager, is there a way I can manually test that I have everything wired correctly? I would like to be able to turn the pump on through kmanager by activating the output if that makes sense.

With it running make sure that all the parameters are met and it should activate.

Thank you for clarifying. With my specific settings, if I change the engine load minimum to 0, the pump should activate when I start as long as it idles above 1000rpm, correct?

As long as all parameters are met it should activate. You should datalog to confirm.

Thank you Spunkster.

After further investigation, I believe I may have wired my relay incorrectly. Currently, I have:

30 - +12 battery
85 - Ground
86 - ECU (E21 VSV)
87 - Fuel Pump +

As I look at the help file in Kpro, it appears I need to have both 30 and 86 connected to +12v battery, and swap 85 to the ECU pin E21.

Am I understanding that correctly or am I all mixed up?

It sounds like you have it wired incorrectly.
