Yes Dogboy the 18" wheel size is there from tips from Karls site. Converts miles / kilometers for your dashboard readout and gives a higher limit to speeds from what I have read.
Hey I think I have stumbled on a good tip from Karls site, text below in red from Jarkko.......
Really REALLY good work compiling all this info on one page!!!
I have a little more info about the: Start Voltage(x100mv) -setting.
I was trying to get my throttle free play a bit smaller and lowered this setting to 9. There was still no error, but the PAS was very, very jerky especially at lower cadences. And I mean unbearable jerky. I don’t know why this happens, maybe the 5V “reference” signal is unstable and altering when motor is under heavy load or something like that.
Might be a good to know for others too, because I’ve had some minor jerking problems with other drives I’ve assembled too.
Of course this might be effective only with some other setting modifications I’ve made. If someone else could also try this out and confirm, we’d have a new little piece on information about this set.
But as I said, this page is VERY VERY good thing for all of us BBS owners. Thanks!
This is the only thing I have read to date that makes sense with what I am seeing with my jerking in PAS. I have my throttle set at 10 from the stock 11 so reading what Jarkko is saying I will raise this number to 12 and see if it helps. Thanks Jarkko. I guess at this point we are all learning here how one parameter may effect things you don't think it will. This setting being under the Throttle page you would think would have nothing to do with a pulsing power band in PAS.
For me removing the dead spots in the throttle is more important than smooth pas so if I end up with smooth pas but too much off a dead spot on the throttle I will choose good throttle response but looking forward to testing this out and see what happens regardless. I should get time to do this tomorrow late afternoon.
Anyone else had similar issues with surging PAS related to start voltage settings in throttle, seems crazy?
