so basically I love the set up but running the canned map Dyno jet sent me and it’s rich at idle and not sure how to adjust it properly. When I attempt auto tune on the canned map the bike runs terrible while auto tuning (lean pops etc) anyone have any suggestions or perhaps a good starting ve table I can adjust with

 

Do yourself a huge favour and get a map from fuel moto costs 99$ but i guarantee that it will be better than any canned map you can get from dynojet's website that are extremely generic.

You can pretty much guarantee that the map is very very lean out of the box as they are designed to be dyno run

more than just the AFR and the VE tables need to be changed you also have the spark and timing that need to be done

if you want to cook your pistons and melt the engine keep using the canned map i bet you if you checked your plugs right now they will be ghost white extremely hot

 

It will do this because "auto-tune" set the afr to a level the stock O2 sensors can use to measure VE, make short runs 10-15 minutes apply the changes and then ride again, "auto-tune" disabled, to evaluate changes, if it needs more work then repeat the "auto-tune" process until your VE changes are 5% or less. Make sure to read the screen so you can see what cells you hit, usually takes quite a few times if your starting map is good for your application, it can only make so much change at a time

 

I was about to echo this, it will run like crap during the start of auto tuning, that is to be expected. As it updates tables it will start to run better.

 

or you could just do the intelligent thing and take it into a reputable tuning shop and get it properly tuned....
Narrowband auto tune sessions with different than stock cams gets to be very frustrating.
