Hi all,
EDIT: PROBLEM SOLVED. I had the ignition wire soldered to battery positive to be permanently 'on'. I then had a keyless push button ignition/ relay wired in and it was still doing it. I connected an on/ off switch and somehow this fixed the problem. Not sure how or why. But suspect it was fixed from the resistance or load of the switch, or the subsequent longer wiring. Without further tests I don't know, but its smooth as butter now.
------‐-----------------------------------------------------------------
I've got a issue with throttle lag, usually it's once I've come off the throttle and go back on, I'll get nothing, then all of a sudden a large jolt. Sometimes a stutter with a couple jolts. I've been trying to fix this issue for weeks, it gets me when going up steep hills and can be a little scary with the jolt. I'll share setup and current settings of Sabvoton & CA.
I've re-pinned every connector, all of my hardware and wiring is perfect. I've even replaced the throttle to see if this fixes issue. It hasn't. I'm running a thumb throttle. I've increased fast rate on CA from 4v/ sec to 6v/ sec and didn't notice anything. I tried reducing controller response (ms) but lowest value is 10. Can't go lower.
My setup:
Batteries: 22s Turnigy Lipo, three 6s 10ah packs and one 4s 10ah pack in series- 92.4v fully charged.
Controller: Sabvoton 72150 controller, with CA plug & bluetooth. As well as external shunt.
Display: Grin Cycle Analyst v3. Currently limiting to 100a using the cycle analyst. Temperature sensor with heat & low voltage cutoff. Certain parameters of the controller may seem high because I'm using the CA for my limiting.
Motor: MXUS 3KW V3 hub motor, laced into a 24" rim.
I hope someone has had a similar issue and can point me in the right direction. I'd owe you a beer, or cup of tea. Or whatever tickles your pickle.
