I shipped it out on a Friday, I had to work all weekend anyway. They had it for two days and two days to ship it back. So my machine was realistically out of service for 6 days total. I would expect 2 days to get there, 1-2 days to flash and two days back. Probably could have it back in 5 days. I also live in northern NY so shipping times could vary.

May we ask what kind of costs were involved?

I could not find info on the MSC site, but I only searched the mobile site.

Thanks in advance.

Disregard… I found it.
$400

I received my reprogrammed ECU from Main Street Cycle yesterday. I put it in the machine and much to my surprise there is a very noticeable difference in the throttle response. I could honestly care less about gaining torque and HP (but those gains are noticeable as well); I just needed the jumpy throttle issue corrected. Main Street Cycle did not disappoint. My wife finally enjoys driving and riding in the machine. If you don’t mind spending a little money, this is 100% worth it.

Have you done any clutch work weights spring etc
bigger tires ?

I’m just wondering how the tune would affect that kinda stuff I’m assuming I’d Likley have to change mine again

New owner here 2023 with 4.6 miles on it.  The pedal is very sensitive in normal and not as bad in work mode.  I was looking at ECU update from MSC after watching video and doing research.  My question is would the clutch 1 kit do the same thing or doing both be the way to go or just the ECU update.

If the clutch 1 kit would do the job it would save a bunch of money and my primary purpose is just using it on my own land with 95% of the time in low gear.  This thing is a little tricky in normal mode when under 10 mph.  I live it a very hilly area with plenty of bumps on the property...hit one under 10mph this thing lurches pretty bad...being a new owner I'm doing a little better with it as i get use to it but wife and kids having a harder time with it and don't want to burn the belt up.  Plus i want it to be fun and easy to drive at slow speeds.  Thanks for any advise.

You could reclock your secondary
To start it’s free just a lil time to do it

What would you suggest reclocking it to?  What is the current clocking of stock unit?  Thank you

For stock tire set up
C1 usually helps out quite well

I’m not positive what stock is at anymore b1 maybe
There not in order like B1,2,3
So here’s a chart nmk has posted

New owner here as well. The MSC Stage 1 clutch kit and trail helix did absolutely nothing for the throttle over sensitivity in a twisty bumpy low speed trail. The only thing the kit did is give you a little smoother engagement in both forward and reverse.
I have yet to determine if my brand new machine has a problem or it's just a "get what you pay for machine". My dealer is 3 hours away so I have not had a chance to get it over to them. I want to try to test drive another machine to determine if I have a problem or it's the nature of the beast. 
BTW I did call CFMOTO customer support from the number in the back of the owners manual. I got an answering machine, left a message and never heard back.

Let me toss-in that in many other reports of throttle issues with the U-force, and there have been many, people have fixed it with either a different/new ECU or replacing it with one for a ZForce. There are also reports of problems with the new throttle controller which requires replacement. CFM knows all this and should step up and fix all complaints such as yours...and to my knowledge have been...but it seems they are starting to dig their heels in.

I think they just have a crappy throttle system. I have the issue with my 2023 that just rolled over 1000 miles. I have learned to control it better but it's still a problem. I disliked it so much, in the beginning, I was going to return or sell the unit.

here are a few things
1. I changed out the clutch kit. That helped a lot to resolve the jumpy take-offs
2. I got familiar with how much throttle and how fast to apply the throttle
3. it got better after a couple hundred miles but I am not sure if it was because of the driver or the machine
4. my biggest issue is when I hit a washboard or something similar I get what I call the oscillating effect where the bump causes my foot to apply unwanted pressure to the throttle so I let off then try to get back in it and I start this perpetual throttle engage disengage. I found that if I rest my foot partially on the plastic running up the center of the floorboard I can control the throttle pressure better.

I have a 2021 Uforce 1000 and it's the first side by side I've owned or operated.  Had lots of motorcycles and ridden 4 wheelers.
From the start, this machine has had a very touchy throttle.  I only have 139 miles on it because I just use it around the house or neighborhood and waited until today to take it for the first service.
I have installed the MSC Stage 1 clutch kit and it made almost no difference.  I sent them my ECU and it made a small difference. 
The dealership said that they are all touchy on the throttle and that they didn't have a fix.  CFMoto hasn't offered them any ideas or fixes.
MSC now says maybe the belt needs replacing but I've driven it only in Low to this point and not hard driving.  Plus, this has been a problem since day one.  I'm tired of throwing money on fixes that don't seem to work.
It seems almost like it's running lean.  Once it gets past the initial throttle engagement, it runs great.  Also, once it warms up it will just stop running if left idling occasionally.  Then it requires giving it some throttle to start it instead of just turing the key.
Anybody have any other ideas?
I actually started a new post with this same info before reading this thread again.  Duh.

[NMKawierider]

I'll toss-in that there have been some throttle module issues and when that wasn't it and CVT mods didn't help, some installed the ECU for the Z Force 950 and that fixed it. I will also toss in that there have been a number of issues with sticky or poorly functional idle air control valves that got fixed with a cleaning with carb spray.

[Blueridge]

I wish that there were actual mechanics at the dealerships these days that would try to figure out problems and come up with a fix.  Now they just shrug their shoulders and say that they aren't allowed to do anything but the basics according to the manufacturers and their dealers.  Pretty much what I got yesterday. 
I am not a mechanic.  I can replace parts and do simple maintenance.  If I can figure out what the part looks like, I will spray it with carb cleaner!
I asked the dealer if they could flash my ECU or a newly purchased one with the program for a Z or even a newer model Uforce 1000.  They said they could only flash according to my VIN number.  And the new ECU would cost about $900.  Not helpful.

I just looked-up the Z900s ecu and yes, 873 bucks....that's beyond insame! 300 would be insame. Check ebay for a used one.
