Default TW-555 Dyno Sheet

2010 FLTRX with D&D Fatcat, SEST, HF AC, and the TW-555

My tune still isn't straight and we want to smooth the A/F line out more before trying to move it to 13 to see what it does to the numbers. They aren't as impressive as some folks dyno sheets with this cam but I am super happy with the performance.

It looks like you gained 17 hp and 11 tq. I'd be pretty happy with that.

Congrats!

Why is the sheet from July 2006? It shows you the speed not the RPM's too. Lines look nice and smooth though, get that A/F straightened out and you'll be O.K.

The computer in our dyno room has a bad battery so it won't hold the date when turned off. And the MPH thing is my fault. None of the tuners were there but I wanted a dyno print out so I started messing with it not knowing wtf I was doing

Def want to try dropping the AF to 13 since it seems to be what most people are running on this cam.

If you click on the MPH at the bottom of the graph in WinPep you will get options, click on engine speed and it will change the graph to show RPM. Your bike should have been tuned to 13.1:1 for wide open throttle. Actualy it should have been tuned to it throughout the whole RPM range then after it was tuned the tuner should have set the AFR tables where he wanted in the MAP load.

We've been messing with the tune when we have time. My buddy is doing it for me so we just goto the shop on our days off and tinker with it for alittle bit. The bike wouldn't idle or take off from a stop without serious throttling when we started.

That's cool. It's very gratifying when you can do the work yourself. Feel free to shoot me a PM if I can help in anyway.

Your dyno tuner deserves credit for using the more conservative and accurate SAE correction and #5 smoothing rather then some who just provide impressive numbers.

The tuners doing allright. IMO he should be targeting 13.0 on the A/F though, he's too lean for wide open throttle. He'd pick up some performance if he richened it up again.
