I also made and added a studding calculator play with it and let me know what you think

Awesome!

Let me know what you think I can add whatever you want into it http://bikemanperformance.com/tech-tips/gearing.html

Once it gets colder out we will play with gearing parameter changes through Digital wrench and see if it changes or messes with the tuning at all, until this summer I hadn't ever messed with that portion of digital wrench so we'll see what happens it may just be writing a different section of...

The lower profile of the piston is the same as stock, the .250" has been added between wrist pin and crown of piston. overall result is a .250 longer skirt when measured from the crown. Polaris did not always offset their wrist pin towards the exhaust skirt like our kit, I believe it started in...

We match exhaust valves to exhaust ports when we port the engine and when we do big bores.

I'll have to get with Neal Monday and see what we are releasing I am sure we will have a update coming for them but we do have tune we were running last year. Email me and I can get you started off with that. Joey@bikemanperformance.com

No I haven't but I will soon, I will let you know that I haven't seen anything in the programming indicating 10hp gain I am guessing it will be about the same as 2016

Not sure what model 860 you are addressing so I'll cover them all. I try not to compare our product to other companies its a small industry so I don't do it. I will tell you how and why we do certain things. The reason we use taller pistons because the stoke bore diameter to piston skirt...

We have tunes made for the Y pipe and every stage level ready to go we had been running them all last season. We will be doing 2017 dyno build from scratch in the next month including all the stage kits plus the Y pipe.

What's changed in a 2017 ECU vs 2016 ECU In 17 these Items have been modified - Timing, Fuel and Idle explained how so below. 1. Timing Angle Correction vs Barometric pressure - Timing has been added as Baro drops to make up for thin air mostly above 7000 rpm vs 2016 this was not corrected in...

Track loader.. are you talking track dyno? We have experimented with track dyno a bunch but found that nothing can replace real world Radar/GPS/Timers for acceleration testing however the track dyno can help with efficiency for top MPH.

We will have a profile similar to the 10 series this Season it's already in the works and will also continue to have our current profile. Our pipe/programming likes the RPM to creep up as it gets hotter so that is part of the reason for the design. The profile we currently use likes a lot of...

The last revision for the AXYS ends in D if yours ends in A, B, or C the yes we have an update. Just Email me JoeyBMP@gmail.com with your Name and GT & ECU serial number we will match up and then email latest revision back to you.

^^^^^ Agreed you will need Autotune or Wideband 2 module to connect with PC5 because the POD300 only reads available channels and the PC5 does not have a AFR channel until you add one of those.

You'll have to lets us know how that works it will most likely run richer. I personally would choose to have the IAT reading temp as close to engine in the intake air stream as it can be without getting fuel or oil back spray so that way the ECU will be adjusting for the most accurate air temps...

1.Fuel - The Stock mapping has approximately a -1% change in fuel per +10 degrees farenheit of IAT (intake air temp) up starting at -40 until you hit 40 degrees at that point the stock mapping gets off, so at 50 degrees fahrenheit intake temp your sled is running about 1% richer than it should...

Okay everyone I am on here to answer your Question's about any of our products or tunes. I will answer any legit questions about HP and EFI Tuning. Many of you already know me but for those who don't - I am one of the main guys in Research and Development at Bikeman. We have a high tech Dyno and...
