  2. Yeah man that was a really accurate article! Seems like through out the years Ive heard that name some where but I guess my mind is going south so I cant put my finger on it..lol.. But again we use a Dyno Dynamics dyno which reads about 13% lower than the 248 DynoJet he was speaking of. In this paragraph (Car A produces 205 hp to the hubs on the Dynapack. This would equate to between 225-230 hp at the flywheel. The same car produces 195 hp to the rollers on a Dynojet. This would equate to 222-226 hp at the flywheel. Furthermore, the difference in power matches up very well with our calculat
  3. Obviously all dynos read different. Most of our customers call our Dyno Dynamics dyno THE HEART BREAKER..lol because it reads about 13% lower than the popular dyno jet. I honestly dont mind cause our dyno is a load bearing unit that lets us apply load for different tuning situations. And honestly I dont get caught up in dyno #'s. I ONLY use the #s as a gauge.. As far as our buggy being off on power I dont think so. For instance a factory polaris 900 xp makes 88hp at the flywheel. On a dyno jet ive watched quite a few and they all make around 65 RWHP..STOCK... You take 13% away and thats 56ish
  4. Had a real productive weekend with my XY 1100. Got my Haltech installed an tuned. We use a DynoDynamics Dyno which usually reads 13% lower than your average Dyno Jet just to give you an idea on the #'s etc etc.. My buggie is equiped with the CVT transmission so maybe someone can chime in on comparable #'s from a stick shift/manual transmission trooper which probbaly reads a touch higher id say with the same 1100cc motor. Anyway bone stock it consistantly made 35.4-36.2 rwhp every pull(we made right at 9 pulls). Immediatly afterwards we wired our Haltech ECU and Haltech dual channel wideband an
  5. Thank you very much for the information I really appreciate all the help Lenny.. Im very familiar with wasted spark but never heard it called a EDIS. Just knew that there had to be some type of a Hal-effect or relluctor type sensor to tell it when to fire since it does not have a Distributor. The Haltech ECU is more than capable to control any type of ignition I want to fire. We use this ECU on my Turbo BMW real street bike that spins a 60-2 trigger wheel 15,000+ RPMs with no problem. Plus having knock control, and a sample rate of 225 per second is great when logging data..
  6. Hey Lenny if you dont mind me asking is that 36-1 trigger wheel that you are using the factory trigger wheel that came on it? or is it an aftermarket wheel you used because the Megasquirt could not fire the factory one? Im about to get head deep this weekend so any info would be helpful. Also do you know what the factory timing is set at from the factory?
  7. This is great information guys I really appreciate it and will make my Haltech install a breeze now! Thanks a bunch!! Also would you all happen to know what size injectors come in our motors? This will make life great when im building my map.
  8. Great post!!! I dont own a joyner but I do own an XY 1100 buggy that has the same SQR-472.. I am building CAI set-up and a nice exhaust as we speak so im excited to see what type of gains i'll see. After I get everything finished I'll probably go out an do some comparisions then come back and start wiring up a Haltech Sprint 500 with there wideband controller. If you dont mind me asking Lenny, Do you know what the teeth configuration is on the trigger wheel? And do you know where I can find a correct diagram of the factory ECU pin out? I went to joyners website and the diagram looks like its
