Re: fuel pump is on when rpm is 0 ?
tested with stim again today ,
when rpm 0 the LED go off after 2sec
once I turn the rpm rotary swithc the LED go on
sound ok right .
but once I plug into my car engine hardness and turn on the ecu power the pump on all the way non stop ( never start engine , rpm 0 )
so recheck the wiring ...

fuel pump is on when rpm is 0 ?
Hi
Just done my MS2 v3 wiring , and found that fuel pump keep runing when I switch on the ecu without start the engine .
I add a relay for the pump and trigger from pin 37 .
do I need to setting something 1st ? ( m using TunerStudio )
