WattsWheelhouse Posted August 1, 2022 Share Posted August 1, 2022 I thought I was just a crazy noob, but my 4 day old sherman max definitely has very noticeable pedal dip. It's bad enough to have been a culprit in a few of my low speed falls when taking sweeping turns. I saw a thread about firmware updates sorting this out, so I downloaded the leaperkim OTA update app (original and English). Unfortunately neither will connect to my wheel. Darknessbot connects fine and says it's on .1.102, but as it's a max, I don't know how that relates to any of the OGs. Is anyone having pedal dip on a shermax? Has anyone been able to update their shermax firmware via the app? Quote Link to comment Share on other sites More sharing options...
WattsWheelhouse Posted August 2, 2022 Author Share Posted August 2, 2022 I was able to get my max to connect to the app by disabling app battery optimization. But I'm getting a "Wrong model, can't update" message when I try to update. Any ideas? Quote Link to comment Share on other sites More sharing options...

I hope they can, as it's definitely alarming to feel like I might fall off the front of this beast when I swing around corners. Quote Link to comment Share on other sites More sharing options...
Rawnei Posted August 8, 2022 Share Posted August 8, 2022 Have you tried calibration? Quote Link to comment Share on other sites More sharing options...

I've been getting used to it, but this is my first EUC, so I'm not sure how abnormal it is. It feels like they slowly dip forward when I turn in either direction, getting worse the longer I hold the turn. Would this thing fall on its face if I turned for long enough? My girlfriend just got a v5f to learn on, so I'm interested to see if it does anything similar. Quote Link to comment Share on other sites More sharing options...

It's not normal at all and shouldn't be used for learning. 1 Quote Link to comment Share on other sites More sharing options...

Im sure i dont know what pedal dip is, but on med and soft pedals have dip like movement except hard where pedals stay leveled nomattwr what you do.

I typically ride in hard mode. Quote Link to comment Share on other sites More sharing options...
Kutvis Posted August 19, 2022 Share Posted August 19, 2022 (edited) I have this same issue. If I turn to another road with decent speed the pedals dips a lot.. If I keep accelerating the pedals stay dipped until I stop accelerating. Same happens also on lover curves on higher speeds. Feel almost like V8F.. ok not so much but you get the idea. I have ridden a bit over 300km (got the wheel a week a go), haven't calibrate it which I will try today. I ride only hard mode. E: Calibrated the wheel, didn't help.

WattsWheelhouse Posted August 19, 2022 Author Share Posted August 19, 2022 I've calibrated it twice now, and it hasn't helped. I'm very used to the dipping now, but I wish it didn't do it. Quote Link to comment Share on other sites More sharing options...
plentora Posted August 19, 2022 Share Posted August 19, 2022 I assume this is because of bad inertia implementation on the firmware. The firmware mostly maintains its angle by integrating gyros and correcting the drifted angle (or gyro dift) values by using accelometer. However accelometers cannot be always used (because of shake for example). So in some cases I would guess the angle calculation goes bollocks (and causes dip) and fixes when you don't accelerate (=acceleration from the sensor can be used to fix the gyro drift). So if you have bad inertia calculation implementation and very picky acceleration correction (bad implementation) then the pedals will probably dip in manouvers. So yes probably something has changed in firmware.. Quote Link to comment Share on other sites More sharing options...
