Hello all, I have a hose that is in need of replacement but I don't know what it's for. It's twords the rear of the engine down lower, I've looked around for a diagram or an exploded view but can't find anything, I'm assuming it's a radiator line but idk. I guess I could just disconnect it and I'm sure I'll find out real quick what's in it.
Also are these hoses cut and sold to fit or do we need to just buy (whatever) length of hose and just get it in there?
Hi, I’ve recently purchased an Ag Pro 1200 to find that it doesn’t have engine breaking. I live on a very steep property and it feels dangerous not having it. Does anyone know if it can be added? Or any other ideas? I’m mostly using it for weed spraying using a hand held wand… so I need to creep along stopping and starting. Thanks for helping.
Using 2019 Honda Pioneer 700-4. Heavy use on very steep asphalt so changed to Carlisle Hard Trail tires. Great move, much better on the asphalt and good in everything but thick mud. Engine brake as much as i can but heavy use on brakes. Are there and has anybody use with after market heavy duty brake pads
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.
Hi I’m new to the forums scene here and I wanted to know if anyone here knows anything about the Hisun 1000cc v-twin motors. I just purchased a used 2015 Massimo Militia with 300 miles on it. I’m attempting to rotate the crank on this motor and it’ll only rotate about 90 degrees and then completely stop. I can rotate the crank in the opposite direction and then it stops at about 90degrees back to where I initially started from. I have the clutch cover off, the stator cover off, both valve covers and both spark plugs pulled. And there is no obvious signs as to what happened to this motor.
I don’t know if anyone else has had a situation like this with their 1000cc or maybe even the 800cc motors. I’m rather stumped and wanted more info if anyone has any to share. I just want to get to the bottom of what happened to this motor.
