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 want to ditch my Kubota RTV-XG850 and its moronic twitchy throttle design flaw, get rid of the problematic engine and the 40 mph purposely throttled speed.
So far, I'm looking at the Honda Pioneer 1000 and the Polaris Ranger 1000, both of which have 1000-1500 lb payload bed capacity.
What other makes and models should I be looking at?
Thanks for the help!

As with any forum you join, there is a requirement for an obligatory introduction... and that seems fair. How else do you get that first post in there without jumping in with some stupid question right out of nowhere?
Hi. I'm Space Ghost. Well, not really, but that was my call sign on my last deployment before an IED made me non-deployable, and I an now retired/disabled, and living on my wonderful VA disability. I did almost 28 years in total between the Army, Army Reserve, and National Guard. 1 deployment with the Reserve (Desert Storm) and 3 with the Guard (1 pre, and 2 post 9/11)
Married (going on 30 years) one of each. (both out of the nest)
Just picked up my first side by side a couple days ago. A 2020 Can-Am Defender HD10 DPS 6x6.
It's in pretty good shape, but as you can probably tell, it's sitting a bit high. Former owner put a lifting collar on the shocks.
The good = almost 17" of ground clearance. (30" tires)
The bad = incredibly steep driveline angles, and a pretty stiff ride.
They will be coming off.
Other than that... clean as a pin and appears very well maintained.
Looking forward to seeing what this forum can bring, and hoping I can bring something in return.

Hey everyone,
I’m in the market for a UTV windshield that can withstand extreme conditions, including high winds, dust, and off-road impacts.
I’ve seen a lot of options out there, but I’m unsure which one will provide the best protection and durability.
Does anyone have experience with windshields that excel in these environments? Are there specific brands or materials you recommend?
I’m particularly interested in options that offer both durability and clarity.
Any tips or personal experiences would be greatly appreciated!
