Having Issue With Fuel Pump Cutting - BA Standalone In Patrol
Hey all trying to narrow down an issue i am having with my fuel pump cutting when going down steep hills whilst crawling at low speed usually engine braking.
Not sure if this is going to be a tune issue or something mechanical. As soon as it shuts off the fuel pump (can hear it stop buzzing as its an external pump) the car shuts off a second or 2 after, i am then able to turn the ignition all the way off and back on and you can hear the fuel pump prime and car starts like normal. i have a speed signal converter hooked up to the ecu.
Cheers in advance. Attached is the stock ba tune and my tune in the car currently

you need to disable vid block and set the speed source to oss. theres actually no need for a signal converter for the input unless its cable to digital, the ecu will read sine or square wave in up to 12v pulses and you can calibrate it in the ecu, but with vid block enabled it uses the hard coded speed settings.
