Re: Inverter Firmware 5.35.R
Does this new version allow can control of one oi board from another? If so can you give an example of what the tx and Rx settings would be? Thanks

Re: Inverter Firmware 5.35.R
Does this firmware allow me the share the analog throttle attached to one oi board to another oi board?
Obviously pre Crc I would just map the throttle pots across can, not sure I understand if the added uptime counter makes this possible or not?

Re: [DRIVING] 1984 Voltswagen Rabbit Prius Gen 3 ZOMBIE
Great work Greg! I don’t generally like taking my bmw modules below 3.4v cell I start getting big deltas under load if I do, so what’s the max battery current you’ve seen pulled? Maybe log idc and udc and go full throttle so we can work out how many kw you’ve managed to extract from the Prius!

Re: [DRIVING] BMW Z3 [FINISHED]
Great work in finding the culprit guys! Interestingly I can get a harsh juddering if one motors inverter restarts due to over current and restarts whilst moving I put this down to a sync error being introduced somehow by restarting in motion, (totally different setup though so unrelated)

Re: [WIP] BMW Z3 [FINISHED]
Could a non linear throttle ramp could be helpful giving finer control of light throttle

Re: [WIP] BMW Z3 [FINISHED]
Cool, yes make sense I get a similar effect at very low rpm pulling away, if you don’t accelerate through it you can set up an oscillation though the drivetrain

Re: Toyota Prius Gen 2 Inverter Controller
Just set temperature de rating in software as high as possible, the hardware is smart enough to over temperature derate

Re: [WIP] BMW Z3 [FINISHED]
Looks like potnom oscillates at the same time? So software based issue and the inverter is just doing as commanded?

Re: Toyota Prius Gen 2 Inverter Controller
You could just scope the encoder output and count the number of pulses through 1 revolution, not sure what to set resolver pole pairs to when using an encoder.

Re: Toyota Prius Gen 2 Inverter Controller
You may require slightly different gains thanks to less than identical component layout? (Just guessing) I’d verify with a current clamp.
Also worth graphing position

Looks like this won’t be an option for me as the longest ratio rx8 diff is 4.3! Lol will be interesting to see what top end you manage

Re: [DRIVING] Project RX8 , Prius gen2, Lexus transaxle to rwd
So good news bad news….. Good news is I can no longer hear how many teeth the diff crown wheel has under regen. Bad news is the diff can’t have been the only thing making a noise so I suspect the gearbox isn’t the healthiest. So that leads to the question find another gearbox or ditch the whole moto...

Re: Toyota Prius Gen 2 Inverter Controller
MIVB and MIWB can just remain unconnected at the inverter end. Not an expert with some firmware as I’ve never used it, I thought the v/hz based firmware doesn’t require current sensor feedback? Using an encoder gives actual rotor speed feedback probably means slip angle can me monitored again no exp...
