    @isak I have swapped my 3.3kw pdm with a 6.6 from AZEO. tested it. worked fine. then did a rookie mistake and accidantly conncted my HV heater to the A/C terminals but reversed polarity. since then it seems like precharge isn't happening. get 44v DC to DC code error on inverter. this is the report from the console:[image: 1789800652617-screenshot-6.png] [image: 1789800653228-screenshot-7.png] [image: 1789800654000-screenshot-8.png] and DTCs:[image: 1789800742760-1000025257.jpg] the f/s charger relay error codeis a code I carry over from before and I suspect it's related to my YAste Can Bridge comunication issue. I can try and install my old 3.3 PDM and see if it's a PDM issue or a contactore or precharge resistor issue? before PDM swap everything was working fine. just had this charger relay code that only affected regen braking. whats your thoughts? cheers

    Hey all! Working on converting my 1991 240sx with 2021 Leaf S Plus components. I bought the 240 chassis with most of the OEM wiring stripped, so I am going to be doing a racecar style, simple 12 V wiring setup. I was wondering if anybody has a recommendation for a good wiring kit that they have used with the Resolve controller with good success? I was considering either the American Autowire 510008 (20 Circuit, $465) or Painless Classic Chassis Harness PN 10102 (21 Circuit, $283). Thanks for any advice you may have!

    +1 on this. Cruise control integration would be awesome.

    I am not sure if the compressor has HVB+ and HVB- going to it all the time. or if it has some contactors in the PDM that turn on with LIN control as well. have to pull the PDM open and see... I do know that the PTC heater has HVB+ and HVB- whenever the Main contactors are closed. so probably the same with the A/C compressor.

    No we do not have any plans to get the specific brake booster from Nissan working, there are other ibooster solutions that are reverse engineered already.

    Yes both pot values are read and a short to 12V or 5V goes outside the specified range and is treated as 0 torque. Nice to hear It's hardware differences that prevent the use of chademo on the later Leaf PDMs chademo is getting phased out and we are looking into some other charging solutions

    Hi! Yeah, the battery heater is not enabled. In the repair manuals they state they start up at -20 C and stop at -10 C. And with them being hard to fit for most builds i never enabled the functionality [image: 1770673976994-1666e9d5-edd5-414c-a121-75252141d87c-image.png]
