434josh Posted December 29, 2018 Report Share Posted December 29, 2018 So I have a positive triggered trans brake solenoid and that sake trigger feeds 12v to a digital input to activate launch control. All works as it should except when i let off of the button i occasionally have an instant loss of power like the coils stop firing for a nanosecond. The transbrake has to be used in reverse and occasionally it will stall when released. Would this be current backfeeding? I ran the same setup on my megasquirt ecu without the issue. I am in the process of installing a Simple Stage bump box which will isolate any backfeeding current but i am curious if you see any issues in the attached log. I did alter the retard table after this as I noticed it bouncing from neg to pos between 3200 and 3300. The first was just a stationary 2 step, second i released the button under load. 2step-brake 2018-12-29 3;13;48 pm.llg Quote Link to comment Share on other sites More sharing options...
