WBC2 on its own, or similar to replace narrow band Lambda sensor?

[Maddog Reynolds]

I'd appreciate your comments, please. My 2015 RC is a road bike, standard intake/exhaust so far. In general I would like an A/F gauge to keep an eye out for changes and to avoid risk of lean detonation/excess fuel washing oil off the bore, especially after fitting a custom airbox I am working on.

But one poblem I want to solve immediately is drastic over-fuelling on a gentle take-off within first 2 miles of starting. Also stutters badly or stalls starting to accelerate gently out of turns in a built-up area in 2nd gear for the same reason-small throttle opening when cold.

My question is "will the WBC2 with its WB sensor work alone (without PC5) to simulate a narrow band sensor, putting the ECU into closed loop control after about 20 seconds of sensor warm-up? And would the ECU be likely to accept Lambda readings so early with cold engine coolant readings? Lastly, if yes, does the WBC2 have a range of A/F settings that vary with an input (say coolant temp) or would I have to pick one ratio for all conditions?"

I would like to experiment, but I'm not rich and can't afford to buy 1 or two expensive units if they don't solve my immediate problem.

Thanks for any suggestions.

I have asked a company selling controllers for the later LSU 4.9 sensor. I'll try to report back if there is anything interesting.

Interesting idea... One thing that you would give up is timing advance with the PCV which is used by most top tuners (and DynoJet) on these bikes.
