Kev,

I got to ask, in your second video, its only idling at around 1200? whys that?

It has taken me 2 weeks of adjusting the fuel map everyday to get a good result. It takes so much time building a map by hand with a data logger. Your Auto Tune is much quicker but you can not see the results like I can with the WB1 commander, which can data log the A/F ratio in real time & play back the recording & watch the A/F ratio while riding live.

99% of dyno tuners do not map below 2000rpm, I have re-mapped my fuel map from 1200rpm to 7200rpm, my bike has a good A/F ratio below 2000rpm & can idle alot lower then the standard Yamaha fuel map without cutting out.

Ah, I see... yeah.

I haven't had time to lately to ride and build up a map. Should hopefully get a ride in tomorrow if the weather is nice.

It's a shame theres no way of hooking up the autotune to a data logger. I can see the AFR in the PCV Software while setup at home but thats about it.

I have been tempted to get an AFR gauge though and wire in to my wideband sensor.

Yeah, I kinda wish I had of done now.
However, what I have noticed, is that without a switch, the autotune wont make any adjustments on the fly, nothing will change untill I go in to accept the trims!

If I had a switch, I could set it to sample and build and adjust the map constantly, so I'll look into that later

Easy enough to made your own switch.

Aye!

Used an old one off an old triumph vitesse.

You have mail by the way.

There is one thing about the kev fuel mod I have not fully understood:

Does it set the air temp to a fixed setting, or does it take the air temp reading and remove an offset? The latter would mean that one setting could be used regardless of the weather you are riding in, the first would mean that you must manually adjust the fuel mod knob depending on the air temperature when riding.

the way I understand it:
the Kev fuel mod takes off a % from the temp reported by the sensor. Meaning it is even more flexible than just removing a fixed offset.
