Re: 07 R6 Bazzaz Cold Start Idle Issue (AFR? BackPressure?)
the mapping needs the cold idle enrichment adjusted. it's too lean or the throttle is not open enough when the engine is cold. it could be a combo of both. I don't know how you can do it with bazzaz's software as I 'have no experience with it. but I can do it to mine with woolich racing flashing system. I would assume you can do it with bazzaz's software too.
don't get too anxious to make a bike perform properly when it's cold. the injection system isn't as sophisticated as a car. so it needs time to warm up properly. even my new bike will hesitate and stumble if I crack the throttle open fast when the engine is cold. that's straight from the factory. I changed my mapping with a flash instead of a piggyback system like the bazzaz and it doesnt do it as bad. your bike will need at least 3 mins of idle time to heat up enough to behave normally. but it should idle on it's own without dying. if you get it to that point, that's all you need to worry about. if its not acting right after 3 mins and the engine temp is 160+ then worry.
