Hi CollinYes, to make a stock inverter from a car work you need to fake a lot of traffic that would have come from other parts of the car - throttle, ECU, battery, etc. If it doesn't see the traffic it expects you get nothing.
And, yeah, that is why people are even doing DIY Tesla controllers. We have gotten Tesla drive trains to work with the stock hardware but it was difficult and Tesla routinely changes the way traffic is constructed. That requires that you can then flash a known firmware version onto the inverter. That all is tough and complicated so other people make DIY boards to alleviate these issues. But, you get issues that way too - you probably will go through multiple board revisions, you need to code up inverter software yourself or modify something, you might never get things as tuned as Tesla or Nissan did, etc.
For what it's worth, I will likely be trying to make a Leaf inverter and motor work outside of a car soon. It seems there is some interest in doing this and so far no one has managed to do it without a lot of cheating (read: using tons of other OEM parts from the car until it works). I want to do it just inverter/motor on a bench.
Can you help me out here...?
I have tried to use Macchina M2 and your interface Savycan. It worked on our 2012 Ampera the first time, bot not on my 2001 Peugeot 406 coupe 3.0 that i want to convert to Leaf motor. First i would like to have a solid CAN database so that i can simulate motor running to use all the gizmos in the car.
So when i connect M2 to 406c OBDII socket nothing happens. No LED nothing. Whilst on Ampera everything starts flashing and i can observe a lot of traffic even when the car is off.
Also i noticed something odd with M2. Usually when i connect M2 to USB and laptop i get "Arduino due hardware on com15" or similar. However sometimes i connect the same, but hardware says something like "bossac port on com16". When i connect Savycan i cant start communication. I have to unplug M2 and play with drivers to get Arduino Due back.
What is your experience with CAN/OBDII, could the pins be switched on OBDII connector? Why would they do such a thing?
