I have a 2020 800 sx with about 16 hours on it. From day one I have heard a clunking noise from the front end going over bumps. Has anyone else experienced this? Also this past weekend while out riding I heard a noise that sounded like the dump bed bounced three or four different times, again has anyone experienced anything like that. Thanks, gary

Most of us complain about the ridiculous noise in the cabin. My wife likes to ride but the noise is a major downer. You can’t even have a conversation without shouting at each other. Well, I manage to reduce the cabin noise by approx 200%!
I addressed the intake that is poorly placed right between the driver and passenger. First, I cut the air filter inlet pipe in half (pic 1). I then reinstalled it upside down (pic 2). I then attached a flexible intake tube (pic 3) and directed it behind the cabin (pic 4). Major difference.
Then I covered the interior engine cover with Dynamat extreme and then 200 mil Chaogang sound deadener / heat shield mat on top of that (pic 5). Since I cut off the intake and redirected it, I completely closed off the intake (engine fence) so no engine noise can come thru (pic 6). It also reduced the heat approx 50%. I did leave on the heat mat that came stock on the engine cover, so it has 3 different mats. It was a snug fit. Major difference again.
My wife rides all the time now since we can have a conversation when we ride. Major improvement to my riding experience. Thought you might like to check it out.

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.

I recently bought an axis 500 and it’s missing a box or something the plug is L shaped I’ve looked through the wiring diagrams and still can’t figure it out. The plug is located right near the battery housing
