I received a bunch of maps from g00gl3it which was great but unfortunately none of them perfectly fit the setup I'm currently running. Figured I'd throw out a thread and see if anyone can help me (PLEASE) and may have a similar map to the ones need.
Last resort is going to the motorcycle shop next town over and getting one made on the dyno but I'm trying not to spend $250 for some fuel corrections.
Mods I have:
Flapper mod
PAIR valve block off
900rr exhaust with scorpion muffler from gsxr1000
0 to 500ft elevation
(this is why g00gl3its map wouldn't work, he's at 4500ft )
Anyone have something similar they could PM?
Of course if I have to get it dynoed and a custom made map then I'll make it available to everyone
Have you tried the so called Simpson map?
I think that one may have been done for a 900RR converion.
Have you tried the 2 Bros Full System map from the P C list of maps? (M112-004)
All 4:1s give a flat spot somewhere, it's just a matter of how bad and where. Honda would push the RPM location down for a 900 RR, but it's likely in the useable zone of a 919. If the fueling is off, the condition is aggravated. You may be sensing this as well, in terms of the overall map across the revs that is.
since you're running the 900rr exhaust, your best bet is to get it tuned specifically for your bike. sorry there's just no way around it. what you can do though is join your local rider forum and wait for a group buy on a dyno tune day. happens all the time you'd be surprised. my group buy brought the price down to $150 with lifetime free re-tuning.

I'll definitely try the 2 brothers map, never heard of the Simpson map. I think I'd wait till spring to get a custom tune anyway.

I'm a bit leery of the 900 RR conversion based on what I have seen so far.
Sure, one loses lots of weight.
But looking at g00gl3it's hp curve, I see a dip from 7000 - 8000 RPM which means a torque anomaly including the rev band where peak torque should be occuring.
Perhaps the classic 4:1 flat spot and occuring up higher in the rev band because of mismatch net effect.
I suspect a dimensional mismatch of the headers to the cam timing and intake area.
I don't think there is any peak HP advantage either.
While I think of it
That map will be based on 4:1s of theirs going back near 10 years.
Back then, their stuff was generally deemed as being poor, worst of the worst is my recollection.
So, the map may reflect that, as in fueling adjustments needed to compensate for exhaust induced anomalies all the way back to the inlet side of things.
Such corrections will likely not be in the rest places, or by the right amounts, for a 900RR based conversion.
A really good tuner is the obvious ideal.

actually, the simpson map is based off of the 2bros map and i found the 2 bros map decently good, loved their pipe i had as well and their map ran well with it. the simpson map just gave a stronger top end finish but then again it was fairly rich as well.

Good to know, and how did you find that out ?
Sincere question, I'm not challenging.
The one I have has nothing in the Notes section, so I've been flying blind on this.

its stated in the thread that introduced the map and invited people to try it.only it was announced after people said they liked it lol.

The cold start issues did arise in September. I think mine has developed the infamous curse because the problem continued even when we had summer like weather a few days. I won't know for sure until May when it warms up again.
