Leaf full stack not reversing properly

[Rustybkts]

Just testing the Fwd/Rev power and the latest trial mod is excellent with plenty of power in reverse.

On the Leaf drive unit application I feel that the Throtramp units of %/10ms should ideally be %/100ms as I have it set to 1% and still is pretty fierce with easy wheelspin in Fwd on my front wheel drive 106 running on 260v.
Parameter limits are 1 - 100.

Regarding the water heater.
Not sure what is happening with the LIN comms as it is displaying tmpheater 207C, udcheater 25v and powerheater 20320W yet the heat is on with 12v on the heater power supply input but appears to be uncontrollable.
I hear a clonk from the heater which I assume to be an overtemp cutout when its hot.

@tom91 do you still require the CAN logs for the reverse power test as I assume they are not associated with the heater.

Do not post that in this thread. go back to your other thread.

Okay it would be worth looking at then, will have a review of code. Timing cannot change, the task is ran every 10ms so possibly add decimals below 1.

Yes provide a CAN log confirm the behaviour now in reverse.

Houston, wehave TORQUE

I did this test just by holding against the brake and vehicle not really moving. Now we have symmetrical torque

Tested the car running Fwd for a couple of seconds then reverse up a steep slope. Loads of power in reverse but fully controllable.

Can one of you please do a free run of the motor with reverse gear selected in the Zombie to see what motor rpm it limits at.

I'll see if I can log this on Tuesday.

So the RPM limit in reverse seems to be about 3500
