I just had a issue with updating firmware from "tazerjl-11.4.4.zfw" to the latest firmware "tazerjl-11.4.6.zfw". Issue was, while driving and advancing the throttle past about 50% I started having no throttle response, the Jeep went into limp mode. I cleared all the codes three different times and the issue persisted. Wondering if anyone else is having this or a similar issue. I rolled the firmware back to "tazerjl-11.4.4.zfw" and all the issues are gone. Pedal Commander has the latest firmware.

Codes:
P1514-87
U113B-00
P2127
U0168
Uo401-00

I did find a video on line that gave me a heads up to this issue with the Pedal Commander. It seems that Pedal Commander uses current from the "TPS" throttle position sensor to power the Pedal Commander. If the TPS sees anything below 4.7 volts it may go into limp mode. So far rolling back the firmware fixed this issue. Anyone else have this issue when using the Pedal Commander? I did put in a ticket with ZAutomotive about this issue. I like the Pedal Commander for off road, by dialing down the settings I can have a much less responsive throttle. This really helps me when I am on really rough ground since I have very little feeling from the knees down.

I don't know anything about the Pedal Commander firmware, or how new it it, but I noticed that you updated over 2yr old Tazer firmware to the most recent wich has been out there for almost a year. If nobody else has had this issue before now, and the PC firmware is recent, it sounds like it might be an issue with the PC firmware?

Also, without digging far deeper into the weeds than I care to, powering a device off any sensor circuit seems like a bad design on a modern computer controlled vehicle.
