non-CANbus will not come out of bottom of shift table

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.

Well I built the NCV1124 circuit as per ashford's diagram and can't seem to get it to trigger at all, so I spent some time adding a capacitor to the input signal without the chip to try and dampen the low frequency. It seemed to work for now after a short drive, no more spikes to 100 right after moving. It will pop up to 8 mph but will settle immediately. I will try the LM2907 later when I have some time. I don't have a oscilloscope so it is hard to diagnose these problems.
