Hi everyone,
I am excited to introduce the most revolutionary technology now available for all snowbikes. PR2 Racing has been developing a snowbike specific ECU for the last year and is now making it available for purchase. Jeff Pineheart, the owner and engineer of PR2 Racing, has an extensive 20 year history at the top of the performance game with Pro AMA Supercross; tuning and engine building for the likes of Geico Honda, Team Monster Energy and others. His approach to our unique needs in snowbike performance is brilliant and refreshing. His goal is to simply get our bikes to perform at the most potential possible in OEM form. We have all thrown a lot of money at big bore kits, exhaust systems,programmers, tuners, nitrous, turbo's etc... to get a little "more" out of our bikes. We all recognize that our bikes run and perform fair at best and PR2 Racing has identified the causes of our issues in the snow and cold temps. Their explanation is very clear and can be validated by us all. The intake runner, the distance from the injector to the intake valve, is very short and combined with low temperatures causes a severe lack or loss of atomization of the fuel, equaling poor fuel burn and performance. Also, "wet" non atomized fuel on the piston finds its way past the rings and into the crank case.
What does the PR2 Racing Snowbike specific ECU accomplish?
#1- To get the most potential out of that 58HP engine by having a tune that is optimum for our conditions. That is 4 or 5 hp more than we currently have!
#2- Eliminating the "cold mode", extra fuel from the stock ECU that happens when water temps are below 160F. Preset by your manufacturer.
#3- Providing precise fuel delivery to maintain the optimum in performance with a 12.8 AFR at ALL altitudes and temperatures.
(This is accomplished by the ECU taking samples of manifold absolute pressure while riding) No tuner or programmer required.
#4- Ignition timing for optimum performance at the elevations we ride. Timing advancement for elevation is a big performance boost.
#5- Precise TPS calibration that is automatic and takes only seconds by you, the owner.
The end result is a bike that performs at its maximum potential without the time and expense of mods and accessories to "compensate" for technical issues.
I have had the opportunity to test the PR2 Snowbike ECU. My bike now starts and idles smoothly and clean; the acceleration and seat of the pants performance is incredible. We did not realize the performance we have been missing by not having the correct tune for our unique conditions!
I addition, there are several "maps" you can choose from with a dial located on the ECU; Snowcross racing extreme, High performance trail, and Deep powder are examples. All maps address timing and fuel requirements for the optimum in performance.
In my opinion, the only three Snowbike set up "must do's" are a thermostat, engine jacket, and PR2 Racing Snowbike ECU. Save the money chasing power and performance with parts that do not correct the real issues, and get real performance gains with a Snowbike ECU.
We have all been in desperate need of this technology and I would like to give a big THANK YOU to Jeff and PR2 Racing for bringing it to us.
