What kind of baseline settings are you guys running to start with when just a slip-on is installed. The directions suck and I am not quite sure how it works to adjust it properly. | ||

depends which slip-on, Rafartist. which one are you running? even with the same pipe you will still need to tune for your particular bike/situation. here's some really helpful info from Dobecks site to understand each of the pots, they go left -> right, 1-2-3-4 or Green-Yellow-Red-Cruise.. . Green Fuel Pot: (functions like a fuel mixture screw on a carburetor) Adjusts for the motorcycle’s fuel requirements during light load operation, from idle through legal highway cruising speeds and steady throttle, at or below the rpm set by your rpm set pot. We have found that manufacturers have generally leaned out the fuel mixtures for emissions to a specific rpm (see below). To set this pot, make sure the motorcycle is up to a full operating temperature, then while in neutral, pick a fast idle that is not easy to hold a steady rpm (V-twins 1800-2200 rpm and multiple cylinders 2500-3000 rpm), hold the throttle at that spot and then slowly and evenly turn the green pot clockwise from its minimum setting, while listening to the exhaust sound. You should hear the exhaust sound change form an irregular and uneven tone to an even and smooth tone. You may also see an increase in rpm as you increase fuel, and if you continue to increase fuel past this point to where the revs start to fall back away, then you can stop and start returning the pot screw back to a point half way between where the exhaust note first smoothed out and the point where the highest rpm starts to fall away. Yellow Fuel Pot: (functions like an accelerator pump) This fuel adjustment adds fuel into the fuel map whenever the throttle is opened rapidly. This pot needs to be adjusted from test riding, by performing brisk roll-ons in a specific gear, and by always starting at the exact same rpm. Try one clock position increases between roll-on tests until you can’t feel any more improvement, and then go back to the last setting that improvement was noticed. Some models won’t require as much fuel as others, so while increasing the yellow by one clock position increments if the motorcycle starts to decrease in throttle response, then turn the yellow back one and a half clock positions Red Fuel Pot: (functions like a main jet on a carburetor) This fuel adjustment adds fuel under large load conditions and is generally required when either air intake or quality exhaust system changes occur. This addition happens automatically using our unique load sensing technology, and similar to the road test procedure listed above in yellow fuel, test riding while increasing red fuel will find an optimum setting. Cruise Pot: This feature allows the tuner to target a percentage of fuel during normal closed loop operation. The closed loop systems on motorcycles targets a signal from the o2 sensor. The cruise pot adjustment coupled with our unique programming gives the tuner the ability to add fuel during cruise without the closed loop system pulling fuel back out. Countless hours of testing resulted in the suggested setting that comes in the instructions, in some cases where the volumetric efficiency has been increased by various engine modifications the need to target a slightly different percentage of fuel may be needed, this is where the range of cruise adjustment may be needed. | ||

Thanks, that is greatly appreciated. I think I have got it pretty close. Someone posted some of their settings to try and without trying to tweak them myself, they are working pretty well. The problem for me is finding somewhere to repeatedly rip on it without Johnny Law stepping in. The damn thing is loud. And I have a terrible time trying to hold the throttle steady at 2000 rpm's, I cant hold it still. Can this be done with the idle screw? | ||

I was told by americansportbike.com that the techlusion would not accomplish what I needed with an aftermarket exhaust. If I am reading this correctly, it should do what I need. I have a power dip in the low and mid ranges and lost some power up top from factory. Would this device do what I need? It looks like it will, but may not be as accurate as other devices. It seems it would be good for the money. |
