Any reason NOT to enable Accelerator Pump On PC-V?
I just ordered a Power Package from Jaime at Fuelmoto with the PC-V and larger baffles in the Dyno tuned series jackpot mufflers for my '09 Roadking.
I saw that they don't normally ship them with the accelerator pump or rev extend features enabled. I called back and spoke to a young lady and asked her to enable them for me.
I was just wondering why they wouldn't enable these features unless you ask them to. The rev extend I can understand but is there any reason not to enable the Accel. pump that you guys know of?
Jaime is going to ship my order tomorrow and I wanted to get some opinions on this so if I'm making a mistake I can call him back before he ships my stuff tomorrow.
The accelerator pump feature is a waste of fuel for all but the most aggressive builds.
I did do the rev extend but the only time I went up to 6200 was to see if I changed it properly.
From first hand tuning experience I do not recommend using the Acc pump on a stock displacement 08-09 DBW model. This can create less than desireable throttle response on these bikes.
I just found out about the Accel Pump feature, so I decided to enable it. I put in 90% throttle, 15% fuel, and 30 revs.
The biggest difference I noticed was the lack of throttle lag now, and it seemed to rev much quicker and with snap. Compared to my wife's 2015 Fatboy (which is a freaking rocket), the response is much better.
So, in a nutshell, I like the feature enabled. As for mpg, gas is pretty cheap these days ($2.15 gal 93 octane) so I'll just keep and eye on it.
I think the above posts show that sometimes it's a plus, other times not so much.
as with many things "tuner" the results depend on the person entering the settings and their understanding of how a motor works- not so much the device.
