Thanks for sharing that Metric.  It is interesting to see how they handled that. 

The original map I was supplied was "all over the map" from 12.5 to 13.7.  I rode with it for while thinking there might be a reason for it, but I didn't like the results.  I talked to a couple tuners who said that they didn't have much experience with v-twins, but race bikes running premium got their max hp with a flat 12.9 to 13.2 A/F.  So I set mine to 13.2 across the board. 

I rode it once since then and really liked the results.  I want to get a few more rides with that tune and then take it back to the dyno.  The weather just hasn't cooperated.

After autotuning mine with LAC pipes and airbox mod I was within 5% of 13.2 in all cells except for maybe 5 which were artifact due to air reversion.  Corrected those back to 13.2 and have really like the results. 

I gotta get around to doing it by gear though.

I'm running Cobra down swept...K & N air filter/ with holes drilled in air box cover. I instructed Dyno tune to give me max power 1st gear thru 4th gear...fifth gear set for cruise and fuel econ.

So dyno tune did the tuning?  I thought you were using autotune?

I wanted to try a custom map gear by gear instead of the throttle positioning. I've never had to shift into fifth gear street racing, or to prove a point.  thought that by maxing out power in 1-4 I could use 5Th for economy. The auto tune will now trim the map, and keep it there during different riding, and physical conditions.
Besides it didn't cost me anything( the best part!)

Metric,

small question.. with the pcv + autotune, is there anything else needed to do the per gear maps? some sort of gear sensor?
