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

Im new to the UTV world but not new to the fabrication world. Me and my friend have been focusing on designing and building a rallye-type setup with a custom chassis and a single seater. With suspension design at a good point, we want to start work on the chassis; however, there is one big hiccup in the way, and that is the powertrain. We've been going back and forth on this for quite some time now and realized that we cant find any great options. We want the engine to be behind the driver and mounted between the seat and the rear axle with a transaxle setup. We aren't going to need any power for the front wheels, as this is an RWD application (Toyota MR2 style setup). It also needs quite a small engine; I would love for it to be 100+ hp and possibly be turbocharged down the line, but power isn't a huge deal right now. Right now its a battle between a UTV engine X trans or a bike engine with a diff.
Although crotch rocket engines are super cool, they aren't built for high-torque applications, and a differential setup for one can range up to $6k, which is pretty ridiculous for our initial budget. (We are not going chain-driven as we have bad experience in that area.).
That's what leads us to UTV x Snowmobile drivetrains. I was initially surprised to find out how much power they have and realized it could be a great option with how they are designed for high torque applications. It is a difficult situation to find a good setup.
The transaxle needs to be either a manual or a sequential setup. And although there are some great engine options, with my limited knowledge in the UTV world, I have yet to find a transaxle that fits or works well with those engines.
So my questions are this: Does anyone know of a good combo or might be able to lead me down a direction? Could it be damaging to an AWD transmission if nothing is connected to the front output shaft and only the rear diff?

I would really like to know what you guys think about this. I'll try not to ramble and make it as clear as I can.
I took this new job with companyX as a fiber splicer a year ago. I have a 45' bucket truck and 10or12 x 8 ft enclosed splice trailer I have to take home. Within the last 6 months all the management in the splice dept left. Now the power/construction management and higher ups are filling in. Just recently we were told travel to our 1st job is not payable even though we are in a company vehicle.
We are union so I asked the union business manager about this. His reply was be grateful you were paid travel as long as you were and that you don't have to drive your POV to the job.
Last week I had 50hr total. The job area is 4-4.5 hrs away. My time was reduced to 44.5 hrs since we were told this travel thing on Tuesday of that week. I wasn't hired for this area. I was hired for area a lot closer to home.
Pay is good. Work is not hard. Insurance is through the union and so far pretty good.
But I hate the thought of having to work extra just to make a 40hr paycheck. Anyone who has to drive as part of their job knows windshield time is not easy.
Anyway what do you guys think. Should I look for a different job or just suck it up because of the decent pay and health insurance.
