No tach signal at idle
I'm running an MS1 as an additional injector controller on a turbocharged 2015 Chevy 4.3 V6 motor. Problem I'm having is I get no rpm signal at idle. At about 900rpm+ works great. I'm getting my tach signal from an MSD tach converter that is hooked into the #1 coil power. This typically wouldn't really be an issue with this setup except the fuel pump control is run off the MS ECU. Since it doesn't see a tach signal at idle it shuts off the pump.
