Does anyone know if they sell a tuner for this unit to adjust AFR and timing to get a little more out of these motors without damaging them. I understand it most likely voids the warranty but still interested.

thanks, Rick

In order to tune the MT05 Delphi ECU on the 750's, you need the following:

USB to OBD2 Port adapter

6 Pin OBD to OBD2 adapter

HUD ECU Hacker Software

I haven't found anyone that tunes the single cylinder 735cc engines.  I have been tinkering with mine but it is far from stock so I HAVE to learn lol.

That’s a far cry from just messin with the engine. Sounds like you have a few bucks in that motor. I bet it sounds and performs like a raped ape. Congrats. Don’t know if I’m willing to go that far but wanted a little bit of horse power and torque from stock. Thanks for the reply.

A picture of motor would be nice to show off.

This is good to know after the exhaust mod I just manufactured for my Hisun 750. Wondering if I will get some fault codes later from the mods. Will I be able to scan and clear codes with that software and cable adapters?

No one sells a tune that I'm aware of. With HUD ECU hacker you can adjust the fuel map and a few other limits.

You would basically need to play with it and adjust. Factory fuel map is set to meet emissions, prevent damage to the engine, and make it operate smoothly.

If the engine is in good shape you can likely get away with a little more fuel and a little more spark advance without any issues, but it's not a big displacement motor and there's no way to adjust the valve lift or timing so you're not likely to get more than a couple HP max, just not worth the effort without making other modifications.

      Coleman 550 Loose Timing Chain
      By Copperline
      I have a Coleman 550 (hisun). Wouldnt start and was sucking instead of blowing through the spark plug hole. Got to the timing chain and it was very loose and for sure the timing was way off. Got the tensioner off and set it to TDC and got the cam gear back aligned. Put the chain back on and set the tensioner as instructed and the chain is still very loose. I extended the tensioner as far as it would go to test and the chain is still loose. 
      Any ideas what could be broken or wrong? Why would the chain be so loose?

      Need help timing a massimo 500 utv
      By Working hard to hardly work
      Hey guys im in the process of rebuilding my massimo 500, and like a dummy I did not mark the cam. Im having a harder time finding timing info than i thought. Can anyone give me a no bs way to where and how i need to align the crank and cams to time this thing? Im still trying to learn how to properly time motors so any dumming down would be appreciated.

      Challenger 750 - junk hisun motors!
      By hisun junk
      I have a 2018 cub cadet challenger 750 with a broke chinese hisun motor and I know that I'm not alone! Almost all the places that were selling them in Colorado don't anymore due to the return for repairs on the clutches and broken timing chains! Don't have yours fixed because it will happen again! They just replace the broken parts with more junk chinese parts! I talked with a UTV mechanic that has replaced one person's clutch 4 times! I have people contacting cub cadet about these problems and also looking into complete motor replacement from hisun junk to a Japanese motor in which the chinese cloned their junk from.

      2019 Massimo UTV 500, timing chain
      By XpressP3
      Had to replace the camshaft and exhaust valve rocker arm due to abnormal wear. The cam lobe was ground nearly completely off!
      Now I have a no start.
       
      The only service manual I've been able to find for this is the HS 500-700 edition. This manual shows a split head with 5 valves. Mine is 2 valves with a machined 1 piece head. The HS400 head looks the same. The problem is that neither of these give an accurate description of how to set up the timing after a cam replacement.
      I watched the video that is posted on this site but that is for the split (2 piece) head. 
      I have attached a picture of how I lined up the timing marks. What have I done wrong?
      Timing gear, all marks to top. Crank (thru armature peep hole) is there. 3rd line, top center but it doesn't sound like I have decompression.
      In fact, my go round put me at least 2, maybe 3 links off (early) and I actually thought it was going to run. I could hear the motor pop but wouldn't fire and run. After I readjusted the chain I get no indication of any fire and sounds like no decompresion. ??

      2017 Hisun Vector 500 Timing Chain broken
      By redneckred
      I was looking at purchasing a 2017 Hisun vector 500, used of course.  The seller is selling it cheap stating the machine had "an unknown oil leak" and his kids ran it low on oil causing the timing chain to brake.  I am not familiar with small engines, but with what is being described, wouldn't this result in some damage to other internal components as well?  Just trying to get an idea if the machine is worth fixing or would it likely need a complete engine/overhaul to make it right before I entertain the thought of purchasing it.
