LDU Regen Vamoose

Post by Boxster EV »

Folks,

My regen has left the building - car just coasts. As far as I recall no changes made to parameter file.

Anyone see anything out of the ordinary here:
params 25.json
(1.38 KiB) Downloaded 104 times
FYI I'm mapping Boost, Fweak, Slip and throtramp over CAN and have been for 6 months (which still works fine).

Any pearls of wisdom out there?

Parameters look ok. Any issue with the throttle pedal?

Pedal is fine and spot values coming through OK. However, your idea gave me a kick down field.

I'd inadvertently plugged in my 'not in use' pressure transducer on pot2, which is CAN mapped to nothing. Unplugged it and we're back in business. Thank you, Johannes.

Tell you what, for anyone out there that has a LDU, and doesn't have one of the below; get one! Totally takes the stress out of playing with the params without needing to be right next to the rear wheel.

If you're not going to actively use pot2, its probably best to sent min/max to 4095 so it is ignored.

I am planning to use it. I just need to find the right moment to bug you into adding idle stuff to my code. ;)
