Power Commander needed?
- Thread starter cold gas
- Start date
which is 160F.... so rather warm. a race bike very often runs around 200 out riding even moderately, 50/50 water glycol boils at ~260 degrees at out riding elevations. these bikes need to be kept warm, and that doesnt just involve the coolant, the oil system im doubting gets very warm which allows gas and water to collect in it instead of evaporating out like in normal operating temperatures. keeping the fueling a little cleaner would help introduce less, but There is also a major need to try and keep the bikes warm, and that includes keeping the icebergs off the cases so the oil can warm up.

Thanks Nick, Good stuff. That is exactly the tuning issues we're working on. Keeping temps up combined with correct fueling is the bottom line. Ring seal, oil in the gas, etc will go away with hot oil in the bottom, and hotter/leaner correct burn up top.
Don't want to mis-lead anyone. The stock bike works awesome right out of the box. We are always tuning and modding to explore ways to maximize performance and continually raise the bar in performance through testing and R&D. We are working on some good stuff now for this season. We will keep posting up to date.
Give us some more info on this controller. What are the features and how are adjustments made.

I'll let Ski-Dooin It update you guys on how the controller actually works. I haven't spend much time with it (yet) and until the testing phase has given some positive feedback I don't really want to speak on it that much.
Some things I will say is that this controller is INSANELY easy to install. Literally took 10 minutes with plugging everything in (and we were talking about it the entire time). No need to replace existing wiring harnesses or do anything to the stock ECU. The unit is a constantly calculating and ever adjusting map based on current conditions and a constantly sniffing wideband O2 sensor. Simply dial in the desired AFR (on the gauge) and the unit adjusts the stock map on the fly and adjusts fuel delivery based on RPM and Engine Load.... NOT RPM and Throttle Position.
The main differences between this unit and the Bazzaz Z-Fi MX are:
- Always auto mapping. The Bazzaz Z-Fi MX is a static map. Even when you auto tune with the Z-AFM it is only an auto tune for that days recording which you then upload to the Z-Fi MX. You will also need a computer to do this.
- Cost. The Z-Fi MX + Z-AFM and needed equipment (bung, probe, cables, switch) are almost $700. This unit is $300 for everything minus the exhaust bung.
- Monitoring. You get to see what your current AFR is "right now" instead of tuning on a computer and then applying settings.
Rush, you really nailed almost all of it right off the bat.
The controller is a Dobeck Performance Gen 4 Unit. They are currently only available for our harley applications, but we are working on expanding our applications. Being big into the snowmobile/snowbike world I wanted to get one out and test it as snow sports our a nightmare for electronics.
The technology is an expansion of dobeck's already famous load based technology, which doesnt limit you to RPM vs TPS maps, your ecu is already doing this, so we calculate the load on the engine based off the factory ecu's injector signal and do the fueling that way. The big step forward with the Gen 4 is now the interface as well as closed loop fueling. I will go through some of each.
INTERFACE- the buttons and mode adjustments are made on the display gauge, fueling adjustments can be made ON THE FLY, so if your out on the hill and feel you wanna change things a little, a few clicks on the gauge and away you go! The gauge is a LIVE AFR display, this means you KNOW what your bike is running at, not assuming a static map is doing what it needs to be doing.
CLOSED LOOP FUELING- Just like modern automotive based fueling an air fuel sensor is used to constantly sample the exhaust and trim the fuel map. Many things like condition of your motor, filter cleanliness, air temp, etc play into how your fuel map translates into AFR, so by constantly monitoring we can keep our fueling spot on every day in any conditions. You set the AFR you want to run in the controller and it makes it happen.
If you have any questions feel free to ask here or shoot me a PM and I will try to explain the best i can, BUT i know like when i showed rush, once you see it even just running in the shop, it is VERY simple and user friendly.
