Lenny Im inquiring on details, specs and/or pics on this diff fix... Im on my second rear diff and in the process of changing the front..Joyner upgraded my rear diff the second time seems to be solid.

PM me with your email address and I'll send you a copy of the instructions. How does your Fast Freddy ECU do? Is there a lot of difference in torque, HP or both? Where is the difference, at high or low RPMs. How much power difference would you say it has over the stock ECU?

Thanks

I have installed a few of those ECU's at No Limits, It is not a install for the faint of heart, the wiring diagram they supply and instructions look like the guy did it on a bar napkin after 5 or 6 drinks, hard to follow and a few phonecalls will get it done, but on a NA motor it works great, and works even better with a turbo, but if you install it on a NA motor then go turbo you have to send it in to get reflashed with a turbo program costs about an extra $150

Instructions with ECU suck! I had to call the guy a couple times but once spoke with him it all made since. The ecu IMO is good just high on price. The ECU is made by TRUST Japan which is Greddy in the USA. Seems to me the tune could be stronger, it has a dead spot at 4k. I'm trying to work this out now. I have noticed that when I retard the timing it gains bottom end torque. Id say that the ecu adds a good amount of torque but most of it is in the higher revs. Alabama doesn't have dunes so I'm trying to dial in that low end power. A built 1100 w/ supercharger is in the works.I'm so power hungry!! :D

I had called Fast Freddys a couple weeks ago regarding their ECU and they wanted $900 plus another $100 or so to install and test/tune on their dyno,think its worth it for what i would gain?

Snowman 6479 you say on a na motor what is a na motor

Naturaly asperated.. IE no turbo, no supercharger

Also if anyone is interested I have a used one from a renegade 800cc that is in perfect working condition, I will let go of cheap

      550 - Diff fluid change and final drive?
      By mcraigchr
      Howdy y'all,
      I have the service manual, but it leaves me with questions.
      1)  It is time to change the diff fluid.  The service manual says 80w-90 for the rear and Dextron 3 ATF for the front!  Is that correct?  That seems odd to me.
      2) The service manual also speaks of the need to change the transmission fluid but gives no detail about it.  What needs to happen here?
      3). The service manual also discusses changing the final drive fluid with 80-90 Hypoid.  Is the final drive actually the tranny?
      Any details about the changing of the fluid or what fluid to use ... or even other things that need to be changed that the manual does not mention would be appreciated.
      Thanks,
      Craig C.

      Coleman 550 Rear Differential Leak
      By Tejun
      Neighbor rode their Coleman with the park brake apparently not fully released. Needless to say, things got pretty hot and even started smoking and the smoke was definitely gear oil smell. Looks like oil is coming from the area just behind the disc for the park break. Looking at parts diagram, there is an oring behind the nut/washer that attaches the flange to pinion shaft. I'm not finding anything on YT that would help with disassembly. Anyone have some experience with removing rear driveshaft ?

      2021 Axis 500 Head Bolt Torque specs
      By Greg Kilgore
      Got a 2021 Axis 500.
      I'm needing the head bolt torque specs.
      Manual states 38nm.
      But saw a video Hisun put out on YT for a 550 stating 50nm + 45° turn of wrench. Didn't think they would be that much difference on a 500 and a 550.
      Seen another YT video on a 2013 500. He did 38nm.
      Really only want to do this job once and done. And done correct.
      Anybody got the answer?
      Going to start this rebuild in a few once this weather brakes. Flooding and then snow and cold here now. But spring is around the corner and the wife has to have this fixed or a Honda pioneer may be parked in driveway soon. She has to be able to ride.

      Hisun Sector 450 (2021) - help diagnose rear diff issue (short video included)
      By camojay
      When we first heard the noise, we immediately stopped driving it...at first we thought it might be a linkage issue, but after further inspection looks like the sound/jolting is coming from the rear diff. Took a video below...
      Anyone know what is creating the diff to skip/jump like this? We drained the diff oil and didn't look terrible, no metal.
      Other info that may be useful:
      1400 miles on it
      Recently tightened the E brake
      P.s. never posted on this forum before, let me know if the video does not work

      Need Rear Diff for Arctic Cat 1000X UTV
      By GaryC
      Unfortunately my rear Diff housing cracked on my 2013 and I need to replace it or find a good used complete differential.  I think the same one was used from 2013-2016?  Any help or referrals appreciated.  Thanks, Gary  (949)370-2575 (in UT)
