Hi i have a stage one FLHRC and the engine is running rough generally when its really well warmed up HOT. sort of staggering... I have a Dobeck tfi unit (fitted before i bought the bike so no instructions). everyone i asked says its prob the fueler causing the probs so ive checked all the connections which seem okies and the lights flash the code saying its connected up good. So i thought id richen up the afr as the sparklers are a VERY light grey. i looked up the instructions on the web but as my unit only has Ki-Tech and TFI fuel controller made by Dobeck printed on it im not sure of how to do it. the nearest lookalike unit i can find is the Ki-Tech pro standard PPF-10718 and it says press mode button once to select mode then + or - buttons for adjustments. well ive tried with engine off and engine running and engine off but ignition on and run on and all combs and i cant get the mode button to light up anything. do you think the units failed or am i doing this all wrong ?
