I have a 2021 Massimo T-Boss 550 which now has a crack in the rear gearcase. A few weeks ago during my usual fluid checks I noticed that the gear oil was very low and there was an oil film on the outside of the case on the side where the plug is. I topped up and cleaned it up. I assumed the the bolt was not sealing properly so I ran it as usual and same thing again and again. So then I was thinking that maybe I need a new washer or something. I cleaned the outside of the casing and was about to top up the oil when low and behold.......I noticed a crack across the top right side. OMG, this thing is only a year old. Any ideas out there on how this would happen and most importantly....how can I fix it?
Any advice would be appreciated because as we all know on this forum it is hard to get shops to work on these wonderful machines. And if I need parts, wish me the best of luck.
Hello everyone I am new to the page and I recently bought a Joyner T2 1100 cc, the wiring harness completely was torn apart. I bought the new harness and I'm having problems trying to figure out how to connect everything. I already connected the engine harness, and I ran the front harness through but there's extra plugs there that I don't see a connection for does anybody have the three harness part diagram for front harness, engine harness, and chassis harness and another question the harness that I took off that was bad did not have a fuse box in the front only one that was aftermarket in the back but the new one I have has one in the front and in the back. From what I'm told it's supposed to have two of them.
2022 L7, looking to upgrade shocks but they are pricey through manufacturer. Need help identifying shocks. The ones I have on there are "Yearben 17480" and the ones I want to upgrade too look to be "Yearben 18557". Can't find them on Yearben's website or via google search. Any ideas?
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.
