Don’t waste your time everybody with rpm motorsports, Omaha. They are people that don’t even work on sxs’s. Trying to tell you how to install things.
Completely uneducated guy tried to tell me I did not install a mid pipe correctly when it won’t install correctly; that was the reason for the video and the complaint that I called him about.
This mid pipe has a 1 inch gap at the rear, and the only way to close it up is with a longer bolt, and to stretch the flex at the Exhaust
After one ride, the rear bolts have disappeared, because how much tension there is on the flex
And the bolts does not line up at the flange
Have a video before and after. And they are telling me that it’s my fault because it does not fit
What kind of idiotic people are even answering the phones these days.?
This guy has probably only read a book and never even driven a motorcycle in his life
Don’t waste your time with this bullshit products
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.
Well now i could use a lil help... i have a trooper in my shop now that has wiring issues... this poor guy paid another shop $1000 to re wire the body control harness, and boy oh boy did they chop it up!!! I am Buillding a new harness from scratch... what i need is a diagram that tells me what each fuse and relay control on the Engine fuse/relay block.. any help is greatly appreciated!!
I installed a new GY6 150cc engine in a Bull Dog Pup 200 and when I put it in drive, it grinds for a second and then runs fine. Works great when i place it in reverse. Could it be from it idling too high? Any help would be greatly appreciated.
