actually, I dont - would that still be saved at the dealer or do they delete these once scanned. I thought about that once they dropped off the bike.

attached is the AFR line - from what I've been reading -this seems still to be very lean, would you surmize they just loaded the stock map and didnt do much dyno time/tuning?

Or am I off base?

if you cant read it, it looks to me to be about 13.2 to 13.4

OK, thanks. This is a completely new world for me, so I'm reading a lot (probably dangerous) and hopefully learning. I did a search on 'heritage air fuel ratio' and saw some banter on other hd forums that appeared to me to say that 13.x was pretty lean - Granted it was for an Ultra, but I would think the mixtures between big twins dont deviate that much.

If you want me to post the link to the other forum for comment, I can - if i can find it again.

Thanks for the help!

The 14.7 to one it came with from the factory is way lean for a wot run you look for 12.x but for a cruising range 13 is fine and will still give you decent gas milage. Whos Tuning yours Motor city?

ABC Harley - Ray's team. I'm starting to mix/confuse concepts here, so I figured out at least part of my confusion - Stage 1 = free breathing and more air - so the A/F... oh heck - for whatever reason I was thinking I wanted the Air portion to be *higher* but of course the lower the A in the A/F the less air per unit of fuel and therefore richer. Duh.

Do you know the ABC guys?
