Ok looked into it some more and appears that is possible. So will probably keep a look out for someone to do a map for the SX SE Performance and then go from there.

Thankyou for the explanations. Looks a lot more technical than i had expected, i'd imagined just downloading a pre-made map and i'd be away. I understand it wouldn't be as perfect as getting it tuned on a dyno, but likely better than the standard map. Am still interested, but will find a local tuner first and see what they'd recommend. Many thanks
Yeah, that'd be the engineer in me - going too technical. You can definitely use it just as you mentioned, just off the bat those downloadable maps will be limited.

We do put base maps out for some bikes. BUT, they don't typically include fuel maps simply because of that volatility from bike A to bike B even with the same mods. As time goes on, more and more maps will be released for it (we call it "MapShare") where this would be an option for you to use as a base then custom tune the fueling based on observed AFR.

Or, guys like VCycle here, will also be offering send in flashes too. Or if you want something custom tuned on the dyno, there are plenty of shops using the hardware all over that can help you out as well tuning the bike for you, for your mods and your fuel - just using their hardware :)

Hey WR-NA or vcyclenut I was looking on the woolich page and noticed a loaded dyno was used. Do you know if the 172hp and 222hp were what the dyno read or were those numbers after converting to the numbers off an ineria dyno?

Motorcycle News did a side by side dyno with the ZX14R (ZZR1400) and the H2 SX SE both in factory form.

https://www.motorcyclenews.com/news/201 ... 1400-dyno/

A derestricted H2 SX SE is going to surprise a lot of people.

The red line is the ZX14R the blue line is the H2 SX SE.

what means 'corrected version' and why do you have to correct?

Lol.
The thing to consider is the dyno for the flash ECU had the stock power listed as 172hp. So that's most likely the power at the wheel or the dyno was a loaded dyno that gives lower numbers.

Where as the MCN dyno had the stock power listed as 192hp. So that's most likely a number converted to crank hp or the dyno was an inertia dyno that gives higher numbers.

The dyno woolich used was 20hp lower than the one MCN used. So in theory the unrestricted sx would have been 43hp higher than the stock ZX14R on the same dyno.
Normally dynos differences are proportionate so the higher the power the bigger the difference will be. IE a dyno that reads 4% higher than another dyno would read 104hp when the other reads 100hp but would read 208hp when the other reads 200hp. So the theoretical 43hp higher isn't exactly accurate.

He was joking by drawing in a different line in the dyno graph or he overlaid the unrestricted graph onto this one.

But there are many factors that affect how a dyno reads and the power a vehicle makes, mainly altitude and weather conditions. At sea level and with cooler air vehicles make more power. So dynos have a setting to "correct" the dyno numbers to what the power would be with the same conditions. Normally they use the SAE or STD scale to give the "corrected factor" so numbers can be compared as if they were under equal conditions.

That said no 2 dynos will read the same. Even the same dyno can give different numbers for the same vehicle because the smallest changes can make a big difference in the result. Tire pressure how hard the vehicle is strapped down onto the roller the temperature of the dyno etc. can effect the reading.

About the 'corrected' version. You can see that abouve 10,000rpm the h2sx stops making power. Just like the H2 does. The h2 was, amongst others, restricted by closing the throttle valves above 10,000rpm. That's ride by wire for yeh :eek:
I guess that without this limitation the power continues to go up, like my 'corrected' version of the graph :lol:
Wishfull thinking? :rolleyes:
