If you contact Dynojet tech support, they will tell you which map will best fit your exhaust. I used a Muzzy map by Dynojet for my Tsukigi full system and it ran fine.
The R77 is so popular, I can't believe they don't have that map for the 14R. As long as the R-77 map is for a ZX-14 and it is 2012 or newer, it will work on all 2012 to present ZX-14s. Also, the air filter is virtually irrelevant to the fuel map. You can use a map tuned for an R-77 and race filter 2012-2018 ZX-14.

That´s so true, can´t belive that there´s no map for R77, i contact tech support and they thell me that the most similar is 17-005-502, but is for european models with akrapovic slip on exhaust, even is for pcv + O2 optimizer (i don´t have it but they say that it must work fine)but i would like to use a map crated for my exhaust, not a similar

You will need to get a tune to get a perfect match for your bike. I would ask about using a Muzzy or some other full system Dynojet map. I would also try the map they suggest. I would almost bet you would feel little or no difference. My experience so far is that tuning AFR does not make a huge difference in performance but it does ensure you are running the engine at a safe AFR.
I've used 3 maps and there wasn't one that was extremely better than the other. As far as performance, they all worked good.
The first map was a DJ map for flies out/stock exhaust. It worked well but no better than the stock map.
I then switched to a Tsukigi Cannon full system/flies out/BMC race filter and a map made by a tuner for that exact setup. The map was even created with a 2008 ZX-14 which is the year my bike was made. If anything, it was an almost imperceptible improvement. The laggy flies response was still there even though I had the flies out and I supposedly had a map to compensate for flies out. I did one AutoTune adjustment and that made the flies response smoother. I didn't touch it for years. It ran good. I didn't have the time or the knowhow to mess with tuning AFR with my AutoTune.
I then switched to Romans map which was for an Akrapovich. It was not a big change from the previous map I had used but perhaps a bit more power at larger throttle openings and a little better response in the flies closed zone of the powerband. I could still feel a lag from improper fueling below 3000 rpm but it ran well and the AFR was safe.
Enter AutoTune. I learned to tune on the road and starting with Romans map, I created my own custom tune with my bike and my exhaust. Still no better than Romans map for his Gen1 ZX-14 and Akrapovich exhaust but it did get the AFR spot on throughout the powerband and the flies lag is all but gone now. I still feel it a tiny bit.
SO I guess I'm saying, don't fret if you can't get the exact map to match your setup. It should be for your exact model of bike. I too would be hesitant to use a Euro map if I did not have a Euro spec bike. Try to get ahold of Chris Kelly at DJ by email. Ordinary techs at DJ do not always seem to get it right but I trust Chris Kelly 100% If he doesn't know, he'll tell you he doesn't know. He would not suggest a map that was unsafe. I do not think DJ maps are designed for best performance but I also do not think that matters very much unless you are racing. DJ maps should be very safe.
I'd ask them about trying a few of there maps so you can see if one feels any better than another.
If you have to have optimum performance, AutoTune or a custom tune by a highly reputable tuner. IMHO, any map that runs well and has a safe AFR is going to be about as good as the next.

Thanks rook, in fact i email to Chris Kelly, he is helping me. My ecua was flashed, and the engine response was very much violent, but didn´t work fine in every rpm range, i buyed a PCV and return ecu to stock, because with PCV i can switch between a powerful map and a map for touring (i do touring too)but i still feel that flash is better, but as i say, there´s a reason for install PCV for me
Appreciate your help
