Shift Target sets to -99 sometimes

A forum for discussing applications and implementations of the MegaShift transmission controller code for the GPIO from B&G. This can control up to 8-speeds and 6 shift solenoids (plus a 16x9 table for controlling a PWM line pressure valve). It has manual and fully automatic modes (16x9 load x speed table), with under and over rev-limit protection, and full data logging of all inputs and outputs (among many other abilities). A TransStim to test your completed board is also available.

Dave,

Okay, thanks for that, it should prove to be very helpful. I will post back when I have a solution.

Lance,

I tried 4144b with this issue, and it still does it. I don't think 4144 was meant to address this, but thought I'd post to say I tried it. Brisk shifter movement from D4 to D1 causes tGear=-99, when Report Shifter Errors is on.
