Tesla LDU board -parameters not saved?

Post by sirpewe »

Hi all.
I have finally managed to get my motor (and car) running again.
I have today tested some with regen parameters.
I set offthrottle regen to 0% and I set brakeon regen to 70% and then save.
When driving the settings work but next time I start settings are back to default (-40% and -25%)?
Any ideas why and or what I should do to get my settings to be stored?
I have tried to set these 3 times...

A few questions:
Did you hit "Save Parameters to Flash"? You need to do that for the parameters to save through a power cycle.
Were you changing and saving parameters while driving? They will only save when not in run mode.
If you did save to flash, did you see a message confirming they had been saved to flash?
If at first you don't succeed, buy a bigger hammer.

1. The first time I was in run mode, another person driving the car and I changed parameters). So I suspected that might be the case and then I rentered when parked and car in neutral.
2. I only use the save parameters to flash button.
I have never seen a message about confirm?

It should show up just above the parameters section.

Hi (everyone).
The reason for parameters not saved is due to inverter being in RUN mode.
When I push "stop inverter" button I can now save parameters.
Thank you P.S.Mangelsdorf for pointing this out.
