It has been too cold to investigate. I did call TS performance as well as EFI Live to see if either of their programmers support Kioti/Daedong/Doosan (as I suspect the entire engine family of t3 and 4 cylinders is common to all). I need to plow, but I cannot really see anything with the hood and loader in the way.
RickB's perspective that it would be hard to deny my warranty is a good point. I believe Kioti had a four year warranty in 2014. Kioti, not in writing, but over the phone told me I voided the warranty. The backstory is this.
I contacted my selling dealer about my tractor skipping out of range in October of 2015. My dealer contacted Kioti of America who informed my dealer that I had voided the warranty. I called the warranty person at Kioti and asked why was my entire warranty voided and, Tim Fox, the American Importer warranty guy, said:
1) I had worked on my own tractor.
2) I had modified my tractor.
3) I had abused my tractor.
Huh?
1) Tractors are tool carriers. I added my own third function because my dealer, at the time, didn't know how. I didn't modify any electrical system on the tractor and my third function looks like it came from the factory.
2) I was sold on the premise that the tractor would regenerate on average every 50 hours. My tractor was regenerating every 8-12 hours because it was always running rich because it wasn't warming up. This same problem struck the entire diesel industry with Tier IV diesel engines and the field repair among technicians was and is to install a warmer thermostat. As measured, the stock thermostat begins opening at 165 degrees F and is fully open at 180 degrees F. After carefully measuring everything, I installed a thermostat that begins opening at 175 degrees F and is fully open at 185 degrees F and also featured a bypass for high rpm operation as the stock thermostat. This meant that my tractor when not under a load wouldn't cool down enough to go back onto the rich warm-up fuel map and the DPF wouldn't load up as fast as it had been. My T-stat swap effectively solved my problem while also maintaining the factory fuel map as at every temperature, the engine runs on the factory fuel requirements and now my tractor is regenerating at a far more tolerable 25-35 hours.
3) When I specifically asked how I had abused my tractor, Tim Fox, the warranty guy refused to offer any explanation or example leaving me to wonder what the definition of "abuse" he used.
Meanwhile, one dealer told me that they sold five Kioti tractors and all of the customers had mentioned my videos and the Russian importer of Kioti has asked for permission to translate and use my cold weather starting video.
