I have had this set-up running for 4 or 5 months. I recently got the CAN integration with the Orion working, did 200 miles or so and then the rains came. At first I got a 55 error on the spyglass (CAN error) so I disconnected the BMS and shutoff the BMS on the spyglass. Then the car would only limp. I repeatedly shut it down and restarted it and finally it worked normally. I figured I have some rain/moisture issue. Battery pack is at 75%

Today sunny day, car working fine and then limp mode again with no error indicated on spyglass. In neutral I can floor it and the rpms reach 950. The amperage while driving is about 8 amps (spyglass)
In diagnostics mode the throttle voltage seems ok (.6 to 4.3 v) brake input from a pressure transducer is 2.1 volts to 4.5
I have called/emailed Thunderstruck they suspect an encoder issue. I just heard back from them and they suggest disabling my brake transducer.
what would regen off look like? Would that be brake current set at 0% ?
Thanks so much:confused:

What does the car do if you disconnect the brake transducer?
