Got a 2017 Massimo MSU500 UTV with thermostat malfunction.. hot light comes on in 4-5 minutes but radiator is ice cold... where exactly is it? The hose neck on the head has nothing in it. I was told it was down by oil drain plug.. only thing I see is water pump.. Is in inside pump housing? Cant find any exploded diagrams that show it.. how to I remove it? any help would be appreciated

This post will explain how to hook up your PC to the ECU of a Hisun/Coleman/Etc UTV to be able to read error codes & engine parameters for troubleshooting purposes.
This is applicable to all small engines using the Delphi MT-05 ECU. This should cover all fuel injected Hisun models, as well as various other Chinese FI engines, as the Delphi MT-05 ECU seems to be the favored ECU solution.
Even though we get actual engine error codes to display on the dash, sometimes we have “pending codes” (not yet confirmed by the ECU) or other intermittent issues that are hard to diagnose, for example a poorly connected sensor that may give intermittent false readings, or a sensor that’s putting out bad date, but not bad enough for the ECU to realize.
The setup requires 2 cables, which are available for around $25 combined, a PC with a USB port, and some charityware software called “HUD ECU Hacker”. This gives the same functionality as the $300 dealer code scanner for a fraction of the price.
In searching I found info about HUD ECU Hacker, but I have yet to see info anywhere about how to hook it up to a Hisun, so I took the leap and bought some cables, and made it work. I will show a step by step of how to do so in post two.
I will be breaking this down into 2 posts:
Delphi ECU Info & Overview (This post) System setup & use Delphi ECU Info (Skip ahead to the next post if your eyes glaze over technical details)
The Delphi MT-05 ECU was developed to allow small engines to use fuel injection. A fuel injection system requires feedback from various sensors to operate efficiently. This feedback allows the adjustment of ignition timing, fuel injection volume, etc to efficiently and cleanly produce the most power possible from a given engine.
The MT-05 ECU has a number of sensors that are required for proper functioning including; Coolant temp, crankshaft position, intake temp, intake pressure, exhaust O2, throttle position, as well as some other optional sensors that are used on more complex vehicles.
From the sensors the ECU adjusts: Fuel injector timing/pulse, Idle air control valve, and ignition coil
The Delphi MT-05 puts out diagnostic data, however it is not ODB2 like a modern car, where is where it gets tricky reading it. There are three options, there is an old 16 bit piece of software Delphi has that is not able to run on a modern computer, there is the motorscanner tool for dealers ($300), or there is freeware HUD ECU Hacker with the proper cables.

Hello everyone, second time posted looking for assistance. First time you all were a great help!
I have an 2013 XY Powersports 600GKE UTV, sweet little machine when she was running. My youngest last fall get it covered in mud, and then blew the engine. I mean she doesn't start any more, and we've even tried rebuilding it since he's in a Vocational School for Power Sports and Diesel course, but no luck.
One of the other members (NVM"something") was really knowledgeable about the machine I had and the engine, all I can tell you is its a CFMoto. If I can't find a replacement, does anyone know if there is one that it can be easily swapped out with, or even minor modifications.
Thanks!
Myron

Looking for information on installing a OBD port or a lite to read codes in ECM.
I can not find a OBD port or a lite to read codes on this R2 with 800cc.
I have code readers and adapters for most ATV's. From what I've found so far. They don't have a connection for to read codes. I may be wrong. That's why I'm asking.
This R2 has had new IAC, TPS, MAP, fuel pressure regulator and fuel pump replaced. This was done by neighbor to try to stop surging. It still surges on start up and then settles down. But once you hit the accelerator it revs up to 2000+ rpm and stays till you block off IAC port in throttle body with finger. Once you do that it once again settles down and idles perfectly.
I want to know what the ECM is reading to help dio it.
This joyner is the first one I've run across. Well second one in a week. (my neighbors 2 of them) The other was a trooper with the 1100cc chery motor that had been setting for years. After cleaning up the fuse box connections. It runs like a top. Had to replace all gages with aftermarket gages. Water, oil, gas, amp. Only problem one was the water temp using original sending unit. Had to install 150 ohm resistor on the input wire to get it to read correctly + - 5 degrees. Close enough. Gas sending unit was/is for a boat tank 6" tall. All SS so it should last forever.
thanks Dan D. aka staind

So I finally got my Quad Gear cab enclosure after waiting out the backorder for three months and to say it's been a huge disappointment is a pretty big understatement. I think mostly because I could make it work, if not for one major issue. The windshield is right next to impossible to see out of. It's a real headscratcher because the side and rear windows are okay. It's not high quality 30 or 40 gauge marine vinyl but I have Quad Gear's stand-alone winshield so I knew it wasn't the best in terms of visibility, but definitely doable for the price. Incredibly, the side and rear windows of the cab eclosure are just as clear as the stand-alone windshield. And the windshield on the enclosure is like 50 percent worse than the stand-alone. It's the same company! I don't get it. If it had just been the rear windshield that was that bad I would have kept it. There are some creases and wrinkles here and there, but I've been using the stand-alone windshield for the past three months so it's good enough not to have to shell out $600 plus for the stock hard windshield. I'd put visibility at about 65- 70 percent. The wife hates it though, which is a pretty big negative. In any case, my original plans were to have an upholsterer change the crappy vinyl out for the high quality stuff and I even sent it to a guy who ended up flaking out on me and refusing to do it. He said he didn't want to charge me $400 for something I paid $200 for. Long story, short, I decided to return it and just get the insanely expensive Kawasaki enclosure next winter since the frigid temps here are about to start climbing in a couple weeks anyway. I first put it on just to see how it would look (I took pics of course) and found that it didnt even seal 100 percent and made it drafty inside the cab. So make that two major issues. At least with the stock enclosure everything will be top flight. Doors will be nice too.
