The Auto Tune unit has 0s in areas where it is not supposed to adjust off the base map, and it is 0ed out at idle-so even the Auto Tune can't adjust this. Anyone care to chime in? I recently spoke to DynoJet about this.

I was told that the only way to counter that decrease in back pressure with a full system was simply to add more fuel and that it would run rich at low rpms, and thus, yes, the grungy pipe. I've heard that if you retain the stock header and EXUP that your bike can run leaner at idle and low RPMs due to proper backpressure. Make sure you select the 'race YCCT', set your engine braking, set your preferred fuel map bias, open your pc3 map then apply it, finally pick your operating temp and select us model or not, and flash! Yes, pick the fuel type that you plan on using, this sets the base 'tune' for your bike. I haven't noticed the hesitation since running it at 75% high load bias.Ĭlick to expand. Sometimes you can feel a slight hiccup when the maps are switched on the stock ECU settings, if you have a good feeling for your bike, such as when crusing to getting on it, there will be a slight hesitation. I have mine set to 75% high load map bias, which Flash Tune says is anything over like 3% throttle, so my bike still runs lean at idle and at stops, etc, but rapidly switches to high load map pretty much as soon as I twist the throttle at all. The interface allows the user to 'lock' into the high load map if you wish, bypassing the O2 sensor function and the low-load 'closed loop' system. The high load map doesn't use the O2 sensor, instead it simply runs a base fuel table. When you get on the gas, over 25% throttle I believe is when the ECU switches from the low load closed loop map to the high load map. This map and sensor are used in low load situations, such as idle, waiting at stop lights, cruising at low throttle, etc. The first is the 'closed loop' map, in which the bike uses its stock O2 sensor. My butt dyno can't tell a difference from the fueling, but it can feel a difference from the 'stock' ECU settings to the optimized 91+ tune on the interface. The power commander 'stock' map is an optimized A/F for a fully stock bike. The zero map is the unaltered stock A/F map. The 'true' stock map is the power commander's zero map.

I have flashed the 'stock' map off of the power commander website. Here are a couple of screenshots of the YCCT maps and the 1st and 6th gear ignition maps. The bike does feel like it has a little extra pep. I went out for a quick ride and was able to power up 2nd gear sit-down wheelies, I tried hard before but it never happened. Aside from the high idle everything worked great. After looking at the 'race' YCCT map closer I believe it may be to blame. I flashed my ECU with the 'race' YCCT map and used the 6th gear ignition map for all gears.

djm PCIII maps into the software, the software then scales the fuel maps for flashing the ECU just like the PCIII does.įlashtune does claim to be actively expanding the software to allow for other adjustments as well. Immobilizer Operation (Normal or Bypassed) Fan temps (stock or 205*F on, 195*F off) YCCT APS vs RPM throttle maps (not directly edittable, can choose between two preset maps: stock and 'race') Fuel table bias (ECU uses a MAP vs RPM and a TPS vs RPM table for fueling, the bias adjusts how much each table contributes to the final value used to control the injectors.) Here are the tuneable features for the 07-08 R1: I got the type 1 ECU flashing interface from Flashtune today.
