Hesitation at 2000 rpm, 100% throttle

[Terryfyd]

I have the 20228 map loaded on my 2005 Rocket III classic.
Aftermarket silencer
without catalyst
Fuel up to E10
Minimum 95 RON (89 RON/MON) fuel
Secondary Throttles at 100%
Rev Limit 6500
Thermo Fan 200 f
Speed Adjust -6%
Speed Limit 299
unchecked O2 sensor
At 2000 rpm when I roll on to 100% throttle she spits and sputters. I'm assuming too much fuel. When I look at the 20228 map I see no major differences in any of the settings in that range. Am i looking in the wrong place? Thanks in advance.

Apologies that I be unable to help with your tuning issues, BUT I had to say, your handle is awesome!

Try reloading the original tune. Chances are it's not anything to do with the tune. They tend to be near perfect right out the "box"
Sounds to me like some of the issues with spark. Make sure those ends are crimped to the coils good.
I would just rule out the tune first.

Curious if/how you resolved this Terryfyd. Got something similar going on myself.

No resolution yet, just staying away from 2000 Rpm. What map do you have loaded?

Have you considered using live data when riding with TuneECU? My guess is with the older bikes you have to use a cable instead of bluetooth, but it can be done. And when was the last time you cleaned your injectors?

 

[Terryfyd]

INJECTORS will be my next step, I immediately thought it was the map because it is always right at 2000RPM.

I have re-mapped a number of times, alternating between a custom map by NelsDyno (i think it’s a modified 20220) and HansO’s (might be Tripps?) 20228 20228 goodbase free flow Cat delete Ramair anti decel pop plus Extra5

I am searching for vac leaks today, then I, too, will look at injectors
