I have been searching and can't find much info on these units. Pretty surprising as every other thing I own I find a lot of info on. Researching for tech info and such it's like no one owns any of these yet I see them everywhere.

Just received delivery of a 2024 AMP Pro. Thought I'd start a thread with my impressions as I use it and learn more. There doesn't seem to be a whole lot of real-world usage information out there on this model. Hope this will help others as they research.
Intended Use Cases
Fire mitigation / slash removal from a 5 acre forested and well-gamble-oaked property. The previous owners thought as much about fire mitigation as I do about fashion: not much. Snow removal Stump pulling General hauling (rock, lumber, etc.) Weimaraner energy depletion. Wasn't an original use case, but a nice added bonus. Experiences So Far
Wasn't impressed that two of the bumpers on the underside of the bed where it sits upon the frame were missing. The metal on metal contact has damaged the powder coating and the frame. I expect a little better QC.
I've only put a few hours on it, so not a ton to report on usage. It isn't quiet; it's silent. I can't even detect an electric note from the motor. I removed (and subsequently replaced) the motor cover noticed that the motor is German and made by Schambuller. The motor controller is Italian and made by Dana TM4. Given the operating specs of both I found on the web, I suspect both are higher quality than the previous Navitas (which is supposed to be decent). The motor is rated at 25 hp and 71.5 lb-ft of torque. It feels very powerful. All the torque is delivered instantly, if desired.
The bed is huge and has an electric dump as standard. Great feature but would like it to go up a bit more. Probably not feasible from an engineering perspective, but I want and I need ;).
Power steering is nice, but vague. Probably common to many UTVs, but I am accustomed to more direct results from input. Plan early and plan often.
In our first full day of usage, we hauled about 1/2 as much slash as the entire rest of the year when I was doing it by hand cart. I may get fatter, but I'll also get more done. After a few days of usage, the battery meter has gone down by 1/10th.
Until next time...

I have a fuel injected UT400 that will start and idle, but surges and sputters at higher speed. It has been sitting for 2-3 months and was fine when parked in garage. I assumed it was a fuel/air problem and pulled the throttle body and cleaned it up. I've ended up replacing the injector, IAC valve, MAF Temp Pressure Sensor, and fuel filter. I've also checked the spark plug, Still surging. I reset the ECU after every component swap.
I plan to pull the throttle body again and look evrything over for any visible leaks, etc.
Any suggestions would be appreciated on next steps. The problem developing after sitting makes me think it should be something simple, but I'm stumped. BTW the fuel was fresh and treated with Stabil.
Thanks.

Trying to get running a 550 Colman running but I think head gasket went bad. Do i just replace with new gasket, clean up and replace or is there more to it?

This was happening to me regularly with the original battery pack, I would drive a few yards and power cut to the motor, no error code, dash works, lights etc, just no drive. Brake lights not on so I don’t think it’s a switch thing. Sometimes it would go back to normal after a few day sitting in the barn. I ended up changing to lithium ion battery 100amp 48v and the problem completely went away for two months so I figured it was something worth the old battteries. Now it’s doing the same thing again, I’ve removed every main electrical connection, cleaned it good, and put it back together. Battery is at100 percent and good voltage. What is interesting is it doesn’t matter how much power I’m drawing, if I’m just creeping along in low or flooring it in high it stops after the same amount of time, about 7 seconds. If I let go of the acceleration right before the 7 seconds I can keep driving like that indefinitely but obviously that’s pretty annoying. Or if I switch immediately to reverse I can back up and go back to F without cycling the key. Has anyone else run into this? It really seems like a safety switch issue to me but unsure what else to check.
