JetCat Fuel Pump Conversion
 

I am trying to convert a JetCat C4 Bus Fuel Pump to a Smoker pump.
the manual says to hold down the "Change Value" button on the GSU during
powerup to get into the proper menu. I do this and then select "Smoker" and the
ECU seems to be setting the connected pump to the new configuration, but then
comes back with "waiting for pump" on the GSU screen. This just continues in a
loop. What am I doing wrong? Tried 2 different pumps and get same results.

I belive the System should have a smoke pump and a regular kero pump.

I would configure one pump after the other. One as smoke and the other as kero pump.

Then in a third step connect everything together with the ECU.
