Anyone smoothed out on/off throttle abruptness on '08?

The title says it all. I haven't tried yet, but was wondering if anyone has smoothed out the on/off throttle transition with the PC5 on an '08 or '09 yet.

I managed to get rid of it on my '04 but I don't remember how and I lost the maps - not that they would do me any good on the new bike.

I have the PCV, but am hesitant to put it on the bike right now. I will be out of town for a couple weeks, then I am going on either a 1,000 mile trip on the bike over the course of 4 days, or possibly a 2,400 mile trip over 8 days (probably not, that's why I have a trailer). I don't have time to put the PCV on now and prove it's reliability before the trip and I don't want to have to remove it from the bike mid-ride for any reason. But - if I could get rid of the abruptness it might make up for the slight risk of having it fail somewhere in the middle of nowhere.

I do this ride with my dad every so often and don't want my Honda to be less reliable than his Ducati - which so far has proven to be bulletproof. Since I am riding with my dad I do not need additional power, but smoother would be good.

Honda less reliable than a Ducati...never happen... and there will be a map at Dynojet that you simply load...and you're good to go.

I've found the '08 to be less choppy on the throttle compared to my '05 when it was stock....Honda put a little electronic trickery into it to be sure of that... but the PCV will make it smooth as silk...

I also like to tighten up the tolerances on the throttle linkage...less play will make it less choppy too...

throttle abruptness

i was able to loose the abrupt throttle by increasing the values in the low throttle opening percentages. go to 5k at 0 throttle, add 7% from 5k to 7500 rpm and 10% from 7750 to redline, now go to 2% throttle and do 10% from 5k to 7500 rpm and 12% from 7750 to redline. your on/off will be responsive but not abrupt. this worked well with any and all combinations of intake that i have been using

I will try it. I just need to soften it up a little bit near neutral throttle. That sounds like you touched on the exact ranges I need.

Thanks
