Will FP3 fix choppy throttle and sluggish response when passing

From what I've been reading here I think the answer is yes, the FP3 will help solve my throttle response issues but I wanted to ask specifically. This is my first "Fly by wire" bike so it could be user error but I've had a few cars with that and haven't had these problems. My bike is a 2016 Ultra, has about 5000kms on it.

My first issue is at partial throttle the deceleration is very "choppy". A very slight input and the throttle seems to "chop" closed, I can't seem to smoothly roll off and on the throttle. Then when you get back on it it seems to bang back open initially then settle down. Makes for an annoying ride around town and gets a little exciting going into corners in the rain.

My second issue is that it seems really sluggish opening the throttle to pass. It's like it slowly rolls the throttle on no matter how hard I hammer it. I don't think its a power issue, its more that it doesn't seem to be making the power available as quickly as I am asking for it.

It's almost like the throttle response curve is the exact opposite of what I expect.

I've read a lot of comments about "throttle lag" and how FP3 fixes that. Is "throttle lag" at the root of my problem? Would a Power Vision unit be a better choice?

The FP3 has a number of throttle response settings that you can experiment with. It does make a difference. At very low throttle, my Glide also tends to be a bit touchy. I just compensate with the clutch.

I've started feathering the clutch a lot more as well, maybe its just a Harley thing I have to get used to. I'm very tempted with the FP3 or Power Vision.

I really like the wheel on your bike. Did that require any front end modification?

throttle responce

the throttle response is regulated by the ecm. yours must be set for slow response. the fp3 has a program to increase the response time, among other goodies you can change on your bike.

Thanks! It's a 21 so, no rake needed. I did replace the stock fork springs to drop the front by 1"....and also eliminate the stock spring's fork dive under braking.

Installed FP3 on my '15 RGS and everything you're talking about went away. Very easy to setup.

Darn...this reply convinced me to order an FP3. Oh well I don't really need to fix the dishwasher this month.

I'll report in a week or two and let people know my experience. For the record, the things I'm hoping to improve are:

- improve throttle control at low speeds
- reduce decel pop and crackle
- reduce heat, I'm Ok with reduced mileage as a result

Those would be worth washing dishes by hand for a couple months!

I just put one on yesterday. Improved throttle response. And cooler immediately. Not crazy cooler. But you'll notice it. Did 160 total miles of auto tune. Loaded that up. Even better. I changed the throttle response tonight when I parked it to moderate plus. I'll post up how that feels. Rain tomorrow so it may be a day or so. Go into the ecm fuel management section. Read the top sticky thread.

Got the FP3 installed this afternoon and after doing the chicken dance and virgin sacrifice I was able to get the bluetooth talking. Something to do with the having the phone plugged into the USB was casing problems. Unplugged it seems to connect just fine.

I have Screamin Eagle Street Cannons on an otherwise stock bike so I picked a simple, slipons only map more or less at random and headed off for a drive around the block. Slow speed crawling seemed to be a bit better but thats about it. I pulled over and set the decel popping and throttle response to their middle settings.

Driving down hill is immediately more acceptable with much less decel pop, it was very bad before, and slow speed handling was definitely better. I can actually do a parade crawl now which was impossible before.

Those two improvements are worth the money to me so its a success so far.

I'm looking forward to the weekend and doing more experimenting as well as an auto-tune and getting out on the twisties.

Glad it worked out for ya. The Standard Plus throttle setting is the ticket for me. No lag. It reacts immediately to any input.

Also. When you're plugged in to the USB it negates the Bluetooth.
