-99 Gear

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.

-99 Gear

Post by shaodome »

So I'm assuming when it says -99 for the gear, there is a problem with the configuration of the gear position inputs. I have triple checked to make sure that none of them are the same. The problem occurs if I move the gated shifter to quickly. If I move it "slow" then it works fine.

I have raised the debounce in the shift settings to 5000, but if I move the shifter quick, it still happens. Thoughts?

Shaodome,

Yes, -99 means no valid gear lever position was found. This is not unusual if the lever is in indeterminate states between gears. The error behavior varies depending on the code version, but for the 4.131 release code, see this: viewtopic.php?f=4&t=240&start=70#p3702
