    electronic clutch

    Just to clarify. I have the ability to change software in the VCU (running my own custom build). The clutch is wired into the VCU -- does not sit between the throttle and the VCU. This is meant to be a FYI in the sense what can be done. Don't expect to be able to buy something like this.

    electronic clutch

    I have played around with a number of things as far the control goes. For bikes I'm not really a fan of the "single input" philosophy. If you like LHRB that obviously conflicts with the clutch. We will try clutch + thumb brake on a bike to see how that works/feels. For me personally I find that...

    electronic clutch

    Suppose you want exactly zero wheel torque (neither positive nor negative torque). The easiest way to do this is pull in the clutch. It is difficult to do this with the throttle -- to keep it in exactly the right position for the torque request for the inverter to be zero. With the clutch it is...

    electronic clutch

    I tried a little experiment and I really like how it performed. I was riding down a mountain on a logging road -- regen was cranked way up. I had the throttle fully closed and used the clutch to control rear wheel regen/braking. It worked really well. Another rider tried it and liked it too. It...

    Post here your Stark Varg issues (or not!)

    The phone caught on fire (from the amount and smoke color the battery inside the phone). Looks like the phone got hit by the concrete pillar.

    Royal Enfield Himalayan Electric using Stark parts

    If/when a production version comes I doubt the solution will be a dual varg battery. Don't fixate on the kwh number and other specs of the bike in the photo.

    it is a brilliant machine.

    Sva elektronika je iz HR. Firma je u Zagrebu, ali inženjeri iz cijele hrvatske.

    @Sunce Just curious, are you from former YU?

    Stark Varg Electronic Clutch

    This might help for some situations, but it has at least 2 major limitations. 1. In a low HP map it cannot be used to help loft the front. 2. It cannot be used to eliminate engine braking. (and there might be more)

    Battery teardown, seeking help to reset the battery

    OK, this time I read more carefully. AFAIK (since i worked on the software which was a while ago) there is no fault storage or remembering. So if it was just the cells, replacing the P group should do it. I cannot be sure, but my guess is something wrong the the BMS. That the BMS discharged...

    Battery teardown, seeking help to reset the battery

    A whole P group is shorted. That battery half is pretty much useless.

    Throttle and traction control on the Stark

    How the throttle works is a highly subjective thing. Also, things such as flywheel for sure have an effect on throttle response even though not directly part of the throttle response. So why do some people prefer the way the Alta responds? Not sure... could be flywheel, could be the throttle...

    Throttle and traction control on the Stark

    We can try both a ramp rate and a filter. Although, flywheel achieves a similar effect even without a filter/ramp-rate on the throttle. As long as the filter is not too slow, it should not induce oscillations. For start I can try a filter only -- adjustable time constant with option to filter in...

    EX: Traction control and whiskey throttle for Enduro

    Ok, so imagine you are writing the software for this. Did the rider really want to do that or was that an "inadvertent input"? Remeber, you are blind and cannot see if what object is in front of the bike; another bike or a log... Now suppose you are a super smart programmer who also rides well...
