Is there any issues with NOT getting a speedo recalibration reflash for a gear change on a 2022 XCR 650 128"? Went to 1.73 from 1.80
I believe it's the other way around. Gearing taller slows the speedo and odometer down. But, if speedo is 5-10% fast already as most are, it should make it more accurate. 1.73/1.8 = .9611 or about 4% slower.You will add more miles than actually traveled but other than that no.
I gear mine up and they read low speed and log less miles. Jackshaft spins same rpm and sled goes faster than ecu thinks it is.I believe it's the other way around.

That is correct and is why you will log more miles than actually traveled.So I believe larger number gear ration (such as 2.0) is a larger gear with more teeth on the drive shaft, and smaller gear with fewer teeth on the jack shaft. This means that it takes more turns of the jack shaft to effect a single turn of the drive shaft. (Note the gear ratios for 1.3" tracks, vs 2" tracks on crossover sleds) So more torque and lower top speed with higher numbered gear ratio. This means, that if you swap out the gear ratio for a higher number... the sled will be going slower than the original gear ratio at any given RPM for the jack shaft.
But I could be thinking incorrectly.
Holly crap, I probably read that post 3-4 times and never saw the from lol 😂. It’s funny how the brain works when you think you know what someone is going to say so we don’t read everything as carefully as we should.No. He's gearing up. 1.73 is taller than 1.8.
And, the best part is that the CVT automatically adjusts to the difference and delivers almost the same mpg.Went from the stock 1.86 gear to 1.74 and no reflash.
Went on a 130ish mile ride with 2 other sleds. They were both within 0.3-0.4 miles of each other.(18 XCR 800 and 18 Sidewinder)
My sled(20 XC850) was around 10-11 miles less on the odometer than theirs, on the same exact trip. Sensor for the speedo is on the jackshaft, jackshaft turns less revolutions with new gear(1.74) compared to stock(1.86). My speedo read lower mph than before and odometer recorded less miles. But is probably more accurate to the actual mph and miles traveled, than it would be with the stock gear.
Going to 1.73 from 1.80, would have the sled moving faster, covering more miles, than the speedometer/odometer shows.Is there any issues with NOT getting a speedo recalibration reflash for a gear change on a 2022 XCR 650 128"? Went to 1.73 from 1.80
I just verified that the most recent update to Digital Wrench II version 4.3 was issued Feb. 8, 2022.Polaris is really fucking this shut up. how in the hell are they allowed to sell something with no support? nope we can't flash 22's ecu's, pbr's etc. WTF they are starting to really piss me off. guys leaving Polaris again like it's 2008 all over again. a lot of the Polaris guys are buying ski-doo this year. good job. there losing the atv/utv market as well.
