Scrappy CHAdeMO to CCS adapter for EV Conversions

Hello folks. As I was progressing with my wiring I had an idea, wanted to bounce off your brilliant minds. While CCS chargers are outnumbering the CHAdeMO, there're still many CHAdeMO ports out there and as the number of CCS vehicles is growing, CHAdeMO plugs are often unoccupied. I have a CCS charg...

Re: BMW LIM based CCS2 Controller

Cool. Looks like removing these two 60ohm resistors joined in series removed the CANbus termination, so the LIM can be put anywhere on the bus. Thanks.

Re: BMW LIM based CCS2 Controller

Cannot seem to locate the termination resistor. Right on the inputs it has the filter circuit (zeners and chokes), then then traces disappear into another layer.

Re: BMW LIM based CCS2 Controller

Must the LIM module be at the end of the CANbus and no workaround?
Reads 120Ohm between the CAN-H and CAN-L.

SDU CAN bus connection

Hello folks.
A quick confirmation. If my SDU isn't the last device on the CANbus I just need to de-solder the R37 terminating resistor?

Re: Voltswagen T2 -76

It does have a bolt pattern very similar to the VW one. Just a few mm's narrower on horizontal so I'm getting away with just widening the mounting bolt holes a bit in that direction. https://pixelfed.fi/storage/m/_v2/530130149058689089/f1538e3aa-7b3151/PMXU9LOwuc4x/XHrXiFuhnwdrYGaIhuJjmfv2wpETH3c2R...

Re: SDU brake lights output!?

While the OI firmware provides such an output at a regen level you can configure, the SDU and LDU boards do not export that signal to the outside world. I see. Is it by chance an option to send a regen message via CANbus? Curious if somebody actually triggers the brake lights during the regen if th...

Not sure if the ones I bought are Bosch, but "fuel injector" was the right key word to finding these on Amazon. 😁

Re: Parameters disappear after throttle! [SOLVED]

Yeah, that's exactly what my interface looked like. The wiring for the power to my OI board was really thin, all I did was increase the gauge of the wires supplying 12v and it solved my issue. It sounds like the problem you're having is different because I wasn't able to spin my motor after I lost ...

Re: Parameters disappear after throttle! [SOLVED]

This indicates that for some reason the wifi module did a watchdog reset. Afterwards the stm32 still communicates at 1M baud and the wifi mod at 115k baud. It might be caused by the data rate being so low that the watchdog resets the wifi module. It doesn't affect drivability as the wifi module is ...

Re: Accelerator pedal dead zone

Has this or similar approach been pushed into the main firmware? Makes sense to me for the throttle calcs to depend on the motor rpm.

Thank you. This thread helps me understand why I had accel dead zone when running the motor for the first time, yesterday.
