Too lean. I wouldn’t go above 13.2 anywhere except idle or if you’re tuning per gear and know exactly where your cruising range is.

 

I got these targets from Nick Marino. Do you know this gen R1 should be richer from dyno results? I’ve heard previous targets around 12.8 were optimal but the newer engines are more efficient and run best a little leaner. I may get a Ecu image built for 12.8 and run my current base flash back to back on a dyno to see

 

I have heard that these engines like a fatter mixture, but bottom line is that you're shooting in the dark if you aren't tuning on a dyno.

 

Data logging is probably a better tool though both the Dyno and logging are great. @Tad158

 

Well the dyno it's the only way to tell what AFR corresponds to the most hp. Logging will nail the tune down for all real world conditions that the bike will actually see on the track...which makes for a better tune.

 

I’m getting a dyno tune now to nail the base map so my Autotune can make minor corrections for humidity and temp. Thanks for the input.

 

Hi, Anyone have Dyno results from various AFRs for the 2CR?
I have the Dimsport EVO and getting the output in a couple of weeks.
I'm then converting the the Wideband O2 Sensor and MyTuning Bike to get a better AFR setting. looks like by the threads above to start at around 13.0

.ga.

Here's my target for active tune currently. Found my bike was thirsty and needed more from 8K up but haven't dyno'd with the updated fuel map yet.
