I am having the SE-255 Cam installed in my Road King. I told the guy at HD that I have a PowerVision and am waiting on a map from FuelMoto for the cam. I asked him if I didn't have the map in time, what would happen because I'm sure they will want to start it up. He said since I already have a map for my stage 1 that it isn't much of a difference from the stock cam it should be ok to start it and ride it home. I told him I was worried about the Volumetric Efficiency and it running lean because the cam should change the way air flows thru the engine. He assured me it will be ok.

Do you guys think I have anything to worry about or will my bike be ok to ride?

Thanks for the input.

 

No problem. It won't run lean because of the cam. Most of the time you'll be in closed loop anyway. Might be a little sluggish though.

 

Thanks.

 

Installed se 255 this week. I have a PCV with auto tune. My bike was mostly rich after the cam install, not lean.

 

I have an EJK and I had to lean it out down low and in the mid, but increased a bit up top. I was pretty damn close with my Stage 1 settings.

 

Oh and get ready to be told how many "better" (more expensive) choices there are in cams, even though you didn't ask.

 

I am running a stage 1 download right now with my Andrews 26H cams and i really can't tell much difference than with my PCIII with canned map from Fuel Moto...I am getting ready to put a PC5 and a dyno tune...hope it will make a difference.
To answer your question about riding yours with the download...it will be fine...

 

funny!!



I would have put in a much better cam, with a much prettier fuel mapping system, on a better day!!!




(how'd I do???)

 

Volumetric Efficiency.....

 

Fuel Moto came through today with the map, so I'm good on that end. LOL at FlamedFXR on the Volumetric Efficiency comment, that was good. The airflow and timing should change with the cam though. When I compared the maps, the Cam map was richer and the timing was different. I am really looking forward to some better low end torque and hopefully I will get a nice Harley potato potato lope on idle. I keep telling myself this is the last mod I'm going to do(don't we all?). Thanks for the responses.
