TuneBoy Software

Although I just ordered up $100 in O2 adapters I decided to go a different way. I do not trust O2 sensors that are not sitting in the exhaust stream (the adapters move the O2s quite a ways out of the exhaust stream), so I had 18mm O2 bungs welded on to the exhaust. All set for tuning tomorrow.

There are definitely a few things that will make the Tuneboy option not for everyone. The expense of buying two wideband sensors kits, the work and cost to install O2 bungs onto the exhaust (which is really a shame, since the factory O2's need to be removed anyway, as a tuned bike does not run O2's, leaving O2 bungs just sitting there), and if street tuning, you need a way to wire everything up and essentially have a laptop visible on the bike while riding it that wont scratch everything up or fly off at high speeds needed to do upper rpm tuning. Not an easy task. We will see if it will be worth it in the end.

Well, this has been a sh*t show so far. I am not happy with this software right now, nor am I happy with TuneBoy support. I highly recommend avoiding this software like its COVID-19 until someone has used this software successfully and has provided a guide that fills in all the gaps that are in TuneBoy's documentation!!!!

So, yesterday went like this:

1. Flashed TuneBoy's tune that matches the software in my ECU. In my case it is the file ending with ABAAL1. I took this file and modified the L1 to L4 tables for 10% more fuel, so I would be more on the richer side of things when I start tuning rather than lean. This is where problem #1 occured. All .dat tunes supplied by TuneBoy are supposed to be stock fueling/timing BUT the O2's are supposed to be disabled and the exhaust valve DTC is supposed to be disabled. Well, my bike threw an exhaust valve code with this tune (thankfully I have the Melcodiag software so I can actually see what DTC's are being set). Since this is NOT supposed to happen, I wonder what else isn't working right in the tune, like are the O2's really disabled. I have asked TuneBoy questions previously and heard nothing for weeks. If it takes weeks to get answers to issues like this, this is going to be a slow, unacceptable process.

2. The logging software does not appear to be working. Two issues here. One, it is not reading the LC2 widebands. If I use LogWorks (the wideband manufacturer's logging software), it is showing that my bike is idling at about 15.5:1 AFR. When I use TuneBoy's DucatilogContiM4D software, it shows my bike is idling at 10.5:1 AFR. If it was truly that rich, I would have a problem. Again, what gets me with this software is that it shows 10.5:1 yet when I rev the bike, the AFR's move around, up to 11.5:1. The wideband data is coming in on a serial stream over the com port. So, there are no scaling issues (you have to scale AFR to a 0 to 5V or some voltage output if using analog outputs, but this is a digital serial stream, so it just reads the value sent). If the data stream didn't exist or is not being read, I would expect the AFR readings in the software to be fixed at one number or show error. The fact that they are moving around with throttle, but completely off compared to logworks really concerns me. So, I can't trust the AFR readings right now and therefore cant tune. Secondly, the throttle position does not appear to be reading correctly. I can open the throttle 40 or 50% and the throttle position shows 10% or less on the logging software. Obviously, TP and AFR are the two most important variables when tuning (along with rpm, which IS reading correctly). I am dead in the water with these variables being suspect. And from what I have seen, getting any kind of timely support on this is just wishful thinking.

So, my plan just so I can continue to ride the bike while I wait weeks for Tuneboy to respond is to use logworks and make sure AFR's are at least safe with the 10% more fueling tune. That way, although the bike isn't running perfectly, I will know I am not running the risk of doing any engine damage.

So, stay tuned, or in my case, not tuned.

Here is the tuning setup. All that is missing is working tuneboy logging software. Note the rear cylinder deactivation at idle when warmed up. Don't let this throw you off when idle tuning.

Also of note, the bike still goes into closed loop operation with the tuneboy tune. Not sure if that is supposed to happen or not.

So, without the tuneboy software, at least I was able to use the Innovate Motorsports wideband software to log only AFR. Without RPM, throttle position, and MAP, I can't determine what fuel cell it is in and therefore can't make granular adjustments. However what I was able to see in real time was this: With the tune I created with 10% extra fuelling in each cylinder's entire load vs rpm map, WOT AFR varies between 12.7:1 and 13:1. This is pretty much ideal. This would lead me to believe that anyone that is running a slip on with a stock tune is slightly lean at WOT and probably leaving some power on the table.

Cruise is still closed loop and runs 14.7:1. However, even with the 10% richer tune, the transition from closed loop to open loop is lean on the bike. 40% throttle in the 4000 to 8000rpm range is quite lean, around 15.5:1. You can feel where it is lean riding it. It is noticeable. This definitely needs some work, but is fairly easy to ride outside of this range right now. Once the RPM's increase, even at part throttle, the AFR's come down to better values.

All in all, at least I am confident the tune is "safe" right now. Not where it needs to be, but won't destroy my engine. This should give you a good idea where you would be if you want to run a slip on with the factory tune. You WILL be lean. This is also after I let the bike idle a long time to set the fuel trims. So, 10% fuel added to the fuel tables, self learning for the trims done, and it is still lean in places.

This will be the last update until Tuneboy gets back to me and gets their damn software working for me. I'm putting my bike back together and riding it. At least I know now the tune is safe.

What a nightmare. This is absolutely the hardest and most convoluted way of getting this done. Afr on an ipad strapped to a tank bag rolling down the road? No way to see tps, or map, etc?

this isnt tuning. This is the extreme sport version of guessing. Run a live cam to youtube!!

Agreed. This isn't tuning. That will happen if I ever get working software. Still haven't heard from them.

This was me just wanting to make sure I was not going to damage my bike. I was able to get enough info to be confident of that.

The gopro would have been a great idea.

I got it back together and did a 700km one day trip. It was glorious. Best the bike has ran since I put the exhaust on. The T800 really was not good on my bike, but I have high standards I guess, as others have thought it is OK.

Once able to really tune with proper logging, I have no doubt I will be able to get the bike to run better than stock.

This is a bit of a post to vent, but I also thought I should give an update. Here's an example of the exchange that is happening with TuneBoy. BE AWARE THEY ARE TAKING 20 DAYS+ TO ANSWER SUPPORT EMAILS AND THEY ARE DOING THEM ALL IN SEQUENCE (THEY WON'T SEARCH AND READ ALL OF YOUR SUPPORT EMAILS AT ONCE).

Me: I flashed my bike with your XX tune and it still has an engine code up for the exhaust valve. You told me your tune files disable this, so why is this happening.
Tuneboy 20 days later: Can you send me the exact code you are seeing?
Me within an hour of receiving the email: here are screen shots of both the ecu read and the ecu error code.
Tuneboy: 24days later and still no response.

over 40 days for this issue and counting. There's some great service.

Me: I'm running your logging software (require to collect the data to do proper tuning). The AFR readings do not seem to be correct. When I log the AFR readings in LogWorks (the wideband manufacturers logging software) I get something completely different than what your logging software is showing. However, I see the AFR readings in your software moving around when logging. If the software is not reading the wideband serial stream, how the heck are the AFR readings moving around.
Tuneboy 20 days later: If the software does not see a wideband serial stream, it uses the bikes narrow band sensor readings to approximate an AFR. Make sure you have the proper wideband controller selected next to the com port setting. I have sent you a new logging software file.
Me: Your logging software has no menus or places to select com ports or wideband controllers. Do I even have the right software or am I running it correctly? Also, I did not get the new updated logging software you said you sent.
Tuneboy: 24 days later and no response.

All kinds of issues here. If the software can create the AFR from the wideband serial stream or use the bikes narrow band sensors, the software should give you some indication on which one it is using, so you can know if your wideband sensors are actually being used or not. This is a big deal for tuning. Not great software to leave the user blind to what it is doing and not have this functionality documented ANYWHERE forcing you to rely on a 20 to 40+ day support cycle.

If I ever manage to get wideband logging working, I will detail the steps here so others do not go through this pain. I feel like writing a user manual for Tuneboy, but really don't want to reward a company with customer support that is this bad. On the other hand, I don't want any other fellow V4 owners to feel this kind of pain when they want to tune and be out riding their bikes!

Have you made any progress since then?

Yes, the logging software is now working with the wideband sensors.

When I was using Tuneboy with an 1199, I didn't look at the laptop while tuning. IIRC, you just set the desired AF ratio in each cell and ride with a laptop hooked up. I kept it closed in a backpack, just removing all the windows sleep nonsense. When I got back, I'd look at the table and certain cells were green if they were in the desired range, maybe red if lean etc. Its been a few years since I messed with it.

Did the adjustment of the motorcycle with Tuneboy work? I want to hear more about it.

Anyone got a in depth guide to using TuneBoy?
Does it remove the racing evo logo.

And is Wayne from tuneboy still operating as some people are suggesting he is no longer operating and waiting on products.

Got the tuneboy followed his guide and worked fine even using windows through bootcamp on a Mac.

Did have a bad flash the second time but that’s because windows was updating and doing a malware check.
