cycling TCC locked unlocked

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.

Simon,

First, try the latest code: http://www.msgpio.com/manuals/mshift/V41code.html as this might have already been fixed.

Then post your MSQ and a datalog of the problem, it's the best way for us to see what is going on. Sometimes it's the only way....
