I just installed a set of SE255's in my 2009 Ultra with Fuel Moto Dyno Tune mufflers and their high flow air filter on an otherwise stock 96" motor. I also got a map for this setup from Fuel Moto. I saw where Jamie plans to do a comparision between the 255's and the Woods cam and someone on this forum is sending him a set of 255's for this comparison. This leads me to think that FM has not developed the 255 map I got from them using their dyno. While I have no complaints with my current map I wonder if anyone else will share the map they have if they are using any map different than the base map they got from FM for this setup, either through the use of their auto tune system or through a dyno tune. I'm just looking to make a comparison.

Thanks

You know what "they say"? "If it ain't broke, don't fix it".

Also as far as a comparison; apples and oranges...
The 255 hits early in the RPM's and starts to drop off or go flat around 4200 or so, where as the Wood's are a mid to high end cam, so there's not really a comparison..

However there is a comparison between cams
like the Andrews 48H though and the SE 255.
The Andrews and the SE are a lot a like,
but the Andrews goes out a little further out than does the SE.
Both are low end torque-y cams.

 

I wouldn't come to the same conclusion. FM is going to install and tune the 255's and 555's in the same bike on the same day for a very accurate A-B comparison. That way nobody can say "Different bike, different day, apples and oranges." This wouldn't suggest to me their existing map for your bike is anything but up to their reputed high level of accuracy. Ride on!

 

Turn your email on and I will send you mine Jamie tweak onceafter he sent it the first time. I have 3 runs with the auto tune tables accepted for a really decent map.
