I have a KIT ECU fitted to my bike a few days ago, but ran into a few problems while trying to adjust the stock (actually empty) fuel maps to have some not-that-weird AFR curves.
A good friend of mine is running a local DynoJet tuning shop, so he has some knowledge about tuning bikes like this, but unfortunately not much (okay, I think actually ZERO!) people have knowledge about the KIT ECU tuning here at Hungary. We tried to do our best, but I am still not satisfied with the results, so I am here to ask some help.
The best docs I could find about KIT ECU and tuning was the following: Kawasaki KRT kit ecu tuning Factory Pro
Unfortunately it was written for an older bike, not having ETV, IMU, TC, and all that fancy hardware...
I know that tuning the 2016 ZX-10R KIT ECU might be a bit tricky because the ETV opening might differ from the actual throttle grip position. To overcome this situation, we tried to use the built-in logging feature of the KIT software, so we had some information about actual ETV opening on the lower rev. ranges before the ETV actually matches the actual grip position.
Attached the fueling map that is currently on the bike for "Comp. Map for Injection #1, #4". The compensation map for injector #2, #3 are the exact same.
The other picture is the output of a WOT (100% throttle all the way) pull with actual AFR measurement.
My biggest concert is about those rich spots around 6000-7500rpm and 8500-10000rpm. A decent amount of fuel (around -10 to -15) has been removed already, as you can see in the maps. Should we pull a little more, or there is something we are doing wrong? :dontknow:
The bike is more-or-less a stock one. Running the stock air filter, stock headers, catalytic converter still in place, and an Akrapovic slip-on muffler.
No mechanical modifications to the engine.
EDIT1: I am worried about the ETV, because for a WOT pull, the first time the ETV actually gets 100% open is around the 8000-9000rpm range. This is definitely something that needs to be checked while writing the fuel maps, but correct me if I am wrong.
EDIT2: Another change I was considering to rewrite the actual throttle positions in the map, because the higher range now only has 50%, 75% and 100%. Don't know whether having more resolution up there (50%, 60%, 80%, 100%, for example) would help anything on the tuning.
Regarding the cat. converter, I will upgrade to a full race system over the winter. There are 2 track days left from the season, and I would like to get the best out of the current setup. It also makes some preparation for the next season, so I have done most of the trial and error regarding the KIT ECU, and can start the next season with a good basic setup.
Still I need some clarification about the injection compensation maps in the KIT ECU. The vertical axis is the TH [%], indicating throttle, I bet. As none of the tuning manual and the application itself have been really helpful about what it actuall means, until this point I thought it relates to the ETV opening angle.
So my question is, when you do a dyno pull at a constant throttle GRIP position - lets say 80% -, what parts of the injection compensation map do you update based on the measured A/F mixture ratio? Do you change only the row that matches the throttle GRIP position (the 80% row in this example), even in the lower rev. ranges?
The current map was not made in this regard. We thourgh the TH [%] is related to the actual ETV opening, that certainly did not match the actual grip position in the lower rev. ranges. This might be an error in the method we used before...
Which ETV map do you mean? All I have that is related to ETV is the "ETV Adjustment Map" for all gears and power modes. These maps are full of 100, so not that useful in this case.
This was the reason why I tried to use the built-in logging functionality of the KIT software, to have some idea about the throttle position to change for a given dyno pull.
Attached the ETV related screenshots. That is all I see right now.
In the meantime, I found the following video about understanding the ZX10R ETV: Kawasaki 2016 ZX10R ETV Guide
The map that the guy is showin in the video is something that I am unable to access through the KIT ECU software.
EDIT: It seems that the map(s) you are referring to is something hardcoded into the race ECU, and Kawasaki did not make it public, even for reading the actual values. As far as I see, the Woolich guys cracked this part of the .bin file, so the Woolich software is able to both read and write them.
Yeah that's what was confusing me. The ETV map can't be made a legit 1:1 via the KIT software, even though it looks like it is on your screen shot. I have have the datalogger files to prove it from my KIT ECU.
As for pulling your very rich zones in the fuel map, I'd start mechanical by allowing more air flow to move through the motor. The KIT ECU setup is for full racing situations, so the factory never made the system's "baseline" around the full stock bike. At the very least pull the metal mesh screen off the factory filter (per the KIT manual) and get a decat pipe. This will lean out those areas of your fuel map without you pulling massive amounts of fuel.

Those ETV maps can be adjusted from 50 to 100. According to my understanding, 100 means that the ECU will set the ETV to the angle that is coded into that hidden map. If I start to decrease those values, the ECU will decrease the ETV opening compared to the built-in maps.

I have a K&N filter at home, so might give it a go. Don't want to spend much time (and money) hackin' mechanical stuff on the bike, if it will get a new exhaust system off-season.
Anyway, I am surprised that after spending a ton of money on the KIT parts, it is still a piece of shit (sorry to say that, Kawi!), because there are some important parameters still uneditable. :2bitchslap:
Is it possible to adjust the fueling per gear through the KIT software?
Went through the available maps a few times, but was unable to find anything relevant...
