Default Need a map for a 88 cu with S&S 509 cams

I have a 2006 Fat Boy with a basically stock 88 cu. I have a Vance and Hines Vo2 air cleaner, Rinehart 2 into 1, and it has 25 degree 6 hole injectors (Fueling 3.91 gs) which are supposed to be direct replacement for OEM 27625-06/A

I would like to put a set of 509G cams in the bike, but so far I can't find a map to start with. I bought the ThunderMax from Fuel Moto and I e-mailed them about a map. They replied that they don't have anything and to pick something close. Anyone have a map they would be willing to share, or advise on a decently close map to start with? I am a little surprised that I couldn't find a base map for the 88 with 509s. Seems like 509 are a fairly popular cam for the otherwise stock 88.

BTW, anybody know a good dyno tuning shop who works with the ThunderMax system in reasonable proximity of west Texas? I would like to take it to a professional tuner, but I haven't come across anyone yet. Voicemails to ThunderMax have gone unanswered.

Thanks

Don’t have my pc at home, but looks at the maps and find a 525 cam and use that map for the 509 cam. It’s simular I/C and will work for the timing set up. The auto tune will take care of the fuel. Use the map with the heist number as it will be the most current set up.

I looked around and they do not have an exact match, nor anything that is really close. what bike and what add ons beside the cam? I take it you already have the tmax, where did you get it?


the stock cam has a similar duration, the biggest difference is the intake close and thus the ccp of the engine. I would get the newest map with stock cams and the add ons close to what you have. The larger the map number the new the map

sounds good, if that fits your exhaust style then also look at 757. the 26 has a much later closing event than the 509 and the duration is more as well. The biggest difference is the timing. try one and let it tune in then you can just copy the timing map from one and paste it to the tune you already have loaded and see if it makes a difference. The 769 has a more aggressive timing map than the 757. I did the same with mine and picked up a noticeable amount of throttle response. using a more conservative map. That's not the typical outcome but my set up liked it better.

either way, we are here to help if we can.

just take your time and follow the initiation sequence and it will go well. then be patient as it learns and adapts to your bike. the biggest mistake is people getting in a hurry. Once its all feels good and you have 500 or so miles on it and want to know how you can get better than low 30s for fuel milage we can work over some of the afr settings.

I have an 05 Dyna with a big bore kit head work and ss 510 cams. took me a while to learn the system and had some issues to work out but now it's up and going good, driving between 60-70 I'm getting 45mpg. Push it a little and throw in 80 mph speeds and it's down to 40. upper 30s on the interstate with steady 85mph
