I realize that many of you do not have diesel machines. For those that do, this is for you:
Just wanted to post my experience this past week. Here in Texas, we had pretty good dip in temps. For 4 days it did not get above 25. At night, it was single digits or close to it. I always put Sta-Bil fuel stabilizer in the storage tank (30 gallon). And up until this tank I was using Power Service (white bottle) for anti-gel. Never had an issue.
This tank, however, I switched to Stabil All season (anti gel). It is supposed to good down to -40. Zap. That is a big fat lie. I put in twice the amount called for in the instructions. Result was less than optimal. I drove the SxS 100 feet (to go get the mail) and it died. I looked at the fuel bowl and it was a cloudy, wax substance. So, the Stabil did not work. That said, I'm not sure that I ever tested the Power Service in the same manner. So I am not saying that one is better than the other.
What are your experiences? Are these products inferior? What do you folks in the northern states / Canada use? Am I missing something?
Hi everyone and I hope that is not a too forward questions for us newbies.
My husband and I are ready (next Spring) to open our newly developed nudist campground in Iowa and we are now looking for interesting activities to host.
Don't worry we are not going to try and sell you a membership because as of 2 weeks ago all of our 50 campsites are sold out for the 2024 season.
It was my job to sell site and now that is complete i am looking for interesting actives host for weekend.
We have 300 acres of woods, grassland, swamps and 2 small ponds/lakes and dozens of miles of riding trails.
we have gotten county approval for the complete 300 acres to be clothing optional.
We think we have a great spot for a weekend or several day ATV / mudder event.
Clothing would be optional for all participants and plenty of room for overnight camping and outdoor group showers.
Now we are looking to you pro ATV riders to let us know if you think your group of people would fit in with ours.
Feel free to ask anything you would like to get a better idea of what we offer.
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.
