OK a couple more questions maybe I missed.
It looks like the wideband(s) connect through the factory sensor and that is how they integrate into the TB system. Correct? If so that is pretty darn cool. Do you take readings from both cylinders or??
Can we tune using lambda and stoich values rather than A/F?
Once the base maps are completed, can a simple change to the target AF table keep the fueling consistent but altered to the new AF target or does a change to the AF target table necessitate and retune of the fueling maps?
Wayne... Do you think baffles in or out on a Termi slip would make any difference to how the mid range would be with this pipe and your tune??
The trim maps are an addition to the TuneBoy map in the ECU.
The trim map can be adjusted while the motor is running, the values are in % to make it easy to see the changes that have been made.
The target A/F values in the TuneBoyTrim program are used to calculate the corrections, these are not used by the ECU.
If you have two wide band O2 kits connected the software will see front and rear and correct both in a single pass.
For the dyno operator we have added some cool stuff.
The throttle can be controlled from the PC, this means the dyno operator can be outside the dyno room.
Controlling the throttle from the PC makes sure the throttle holds the correct throttle value as the bike runs through the revs.
If you turn on the "Roll on" mode the TuneBoyTrim software will send the corrections to the ECU after each pass through the revs.
The following YouTube link shows this in action on a 2013 ZX10R.
The ZX10R does not have electronic throttle so I have to hold it steady by hand, the target screen with the yellow square makes this very easy.
On the Panigale the software works the same but it adjusts front and rear cylinders at the same time.
TuneBoy live tuning of Kawasaki ZX10R - YouTube
This video is showing the roll on mode, after each pass through the revs the software compares the measured A/F value with the target and sends the corrections.
The colour of the squares indicates rich or lean (Blue and Red) or Green when the A/F is within 0.2 of the target.
The dyno has been set to go through the revs at a slow rate to make sure the software gets lots of A/F values for each mapping point.
You can see that the A/F ratio at the end of the video is all in the green.
At the end of the tuning you simply save the trim file then flash the ECU using the tune and new trim file.
If you connect the wide band to the bike and take it for a ride (laptop in backpack) it will record the data in the same way.
The iPhone app will make the recording of data much easier.
I am going to add an option to tell the software that you have the narrow band O2 sensors connected, the data from the narrow band O2 sensors can be used to adjust the values in the lower throttle area.
Tuning this way will take longer but I am sure it will get an adequate result, at least at lower throttle.
The reason to use the narrow band O2 sensors is the ease of use as they are already on the bike.
If you get a trim map that has been created on the dyno (on another bike) it will be close enough at higher throttle settings and the narrow band sensors should allow the lower throttle to be adjusted to match your bike..
As for the closed loop, it is correct that you can tune the tables for 14.5/1 in the closed loop area then turn the closed loop on again.
The bike already compensates for altitude, air temp etc. It does not need the O2 sensors for this.
Is there a wide band O2 kit you recommend to use with the Pani and Tuneboy?
The innovate LC-1 can be packaged with tune boy as an option as can a 12-18mm adapter to fit the threads on the Pani
good info, thank you.
is there any point to 2 widebands or do you just use 1 and the cylinders are close enough?
Cylinders are different on the Panigale.
Everything can be done with one LC-1 as the software will duplicate the A/F value if it only see's one input.
In the target screen that shows the two A/F values you simply remove the tick next to the A/F value you want to ignore.
For example: If you have the LC-1 connected to the rear pipe you remove the tick next to the A/F value for cylinder 1.
Once you do this the values will only be stored in the A/F table for cylinder 2 (rear cylinder).
This allows the tuning to be done in two steps.
I think every dyno operator should have two wide band O2 sensors if they plan to tune any V-Twin (or L-Twin).
Tuning both cylinders at the same time reduces the time on the dyno and this is good for the operator and the bike.
do you ever reenable the narrow bands after tuning or just leave it in open loop or do you reenable closed loop with no o2 sensors? can one run two widebands full time and how will the tune boy take advantage of that on an every day real time basis away from a dyno, not logging, just riding?
The current maps we have disable the narrow band sensors and they do not get used.
I don't see the point of turning the narrow band sensors back on.
The code in the ECU does not use any wide band O2 input under general riding conditions.
It may be a good idea to allow some sort of closed loop adjustment using the wide band input, would need to do some tests to see how it works.
so I would just plug the o2 bungs and seal up the plugs and go?
thanks again for answering all my questions. it really allows me to think, which I love to do, and I will definitely get your product soon.
I think this back and forth between you two is awesome. The questions and answers are great. Thanks to both of you.
This sounds great. Are there any available tunboy maps that have been seen to help bikes running the standard exhaust? I am sure there are a lot of us that would be keen to gett better fuelling and heat control with standard bikes, with the ability to update when we in all likelyhood get at least the slips!
Sir! I am going to write a blank check and you may put whatever numbers you would like on it! I Must have this!
request for adding an option:
can you somehow include a feature to set the exhaust valve on/off? maybe by hitting the hi beams and the set button at the same time (or something similar)?
i live in a subdivision with a lot of little kids, and even though i could not care about waking them up in the middle of the night, i do. speed limit is 25 mph, so it's also kinda hard to go through these 90 degree turns with exactly 42 mph in 2nd gear, just to get the bike quieter.
on the other hand, on the interstate, i would prefer to have the bike louder, to wake up texting cagers....
thanks, and i am in for one!
Mine is on the way. I've got the Tuneboy on my StreetFighter already, worked great there and I expect more of the same.
I'm still wondering if a group buy option will be coming due to the level of interest in this product with all of us....
