tuneboy

does anyone know what exactly tuneboy does and does it do diagnostics? ALOHA

Yes. Yes. There's a few maps available as well from the t595 site.

A better question would be "what doesn't it do?" I should have one waiting for me when I get home on Monday! Take a look here -->TuneBoy comparison

The TuneBoy software is excellent. I have had mine for about two weeks and have been working out fine details of my '02 S3 since then. This thing is awesome!

You are able to:

--adjust fuel curves via hard numbers or percentages

--adjust ignition advance via hard numbers or percentages

--view fuel and ignition curves 3-D which may sound like a blow-offable feature, but it is great as it lets you see peaks and holes in the curves that you can then adjust to smooth out.

--Adjust air/fuel ratios that the fuel injection uses as it's goal.

--Adjust fan turn-on and off temperatures

--view all sensor outputs while bike is running

--set 0 throttle position

--view and clear error codes

--test fan, fuel pump, idle stepper motor, and tachometer

And more that I haven't used yet for dyno work.


Wayne at TuneBoy has been excellent to work with and helped me get the software installed and running. Stuff got to my door right when they said it would, and it's bee fun ever since!

I have increased my ignition timing a little ( 0.9-2.8 degrees), smoothed out all of my curves, increased my fuel by 2-3% down low, and 5% up high, and can definitely see an improvement. Revving is much crisper, and I can definitely feel a power improvement by the readings in my butt-dyno! :-) .

This software will let you do alot of tuning and changing of how your triumph runs. You can change alot or a little, it really depends on how much you enjoy tinkering. Once you have the software running right, and have a general tune made that you can just tweak, it only takes about 30 seconds to load your changes--quick and easy!

Highly recommended accessory to any triumph with the programmable ECU.

How does one 'smooth' the curves? I understand how tuneboy could load an existing map and it may have spikes etc up/and down. However, without getting readings off a dyno, what good would smoothing the curves be?

Just curious.

Thanks

Ok, good question.

It's analogy time!

Imagine it's like making your bed in the morning. The "curve" is a three dimensional curve, like your sheet. If you throw the sheet over your mattress, it will generally take the shape of the mattress, but will not be smooth. It will have wrinkles, high spots, and low spots. Now imagine you pull the sheet tight and smooth out all of the wrinkles and excess etc, the shape of the sheet has stayed the same generally, but the small peaks and valleys have been removed. You can also adjust large peaks and valleys and blend them in, or whatever you want. TuneEdit shows 3D curves for the fuel and injection curves and the trim curves for them too. The 3d curves lets you see where there may be "rough" spots that could use some work.

Hope that made sense!

That is exactly how I edited my tune codes. It has taken a while to get it exactly where I wanted it, but the bike really works well now that it is done. If you look at the evolution of the stock tune codes for a TT600, you will see that they graph out smoother as they get newer. It is hardly surprising that they had some real problems early on if you look at the graphs. You really got to wonder what they were thinking! When you save trims from custom tunes back to the original tune, you will also note that what those trims do is smooth things out a bit more. So, with that bit of information, all I did was use the graph to fill in holes and knock down spikes. I suppose there might be some internal resonances that will show up on a dyno. Those could require some local "wrinkles" in the curve, but for the most part, a whole lot of spikes and holes don't make much sense.

You do all that editing with TuneEdit. The basic program, TuneBoy, allows you to do all the diagnostic things that the Triumph gameboy tool does, including setting your fuel idle trim. That is how a dealer sets your CO. Since I don't have an exhaust gas analyzer, I just mess with it until it feels right. The tune codes determine how your bike responds at any give throttle opening and rpm. The fuel idle trim has a whole lot more influence over how the bike responds right off idle or from a closed to open throttle transition. If you have a really jerky off/on throttle response, you can increase the fuel idle trim to help smooth that out. If you can tolerate a jerky throttle, you can decrease the fuel idle trim and get radically better fuel economy, as I discovered by accident. The bike will run pretty hot, too, so I don't recommend that.

After it is all said and done, if you have a Sagem injected Triumph, a laptop or other computer that can get close to your bike, and any mechanical inclination at all, TuneBoy and TuneEdit are probably the best tools you can buy for your bike. Even if you don't do your own servicing, you can check all kinds of things and make little adjustments that make a huge difference. For what its worth, I don't have any connection to Wayne, except that I bought a cable and unlock code from him. I am convinced that if he cracked the codes for Kiehin injection systems, nobody would ever need a Power Commander again!

Cool info - I like the sheet analogy too, and I got that part before - but it will help another person for sure.

My question, was more to the why are the spikes there to begin with? I doubt that triumph has made map adaptive and the ECU figured out that at 4521RPM needs a +10 on some value on its own right?

I know that Triumph engineers create peaks and valleys to tune out emissions or vibration issues, but these are generally larger, more sweeping changes, rather than a single spike at a given rpm.

So, if these spikes are factory designed, why are they there? and what are we doing by removing them?

Not sure what they are doing there. They may be there for vibration as you suggest. There is a hole in the timing around 4000 rpm that is there for emissions or noise. My guess is noise, since my bike is pretty loud around there and always has been. I got rid of the hole and it is louder. My bike also does vibrate a little more now that the peaks and valleys have been smoothed out, but not much. As far as some of the radical gyrations in the numbers, I really can't explain them at all. You would think the factory would have a reason, but if you look at the graph of early TT600 codes, it looks like a moonscape. What is up with that! Smoothing it all out makes a big difference. Since each subsequent tune has smoother codes, I really can't explain all that, unless they were solving some localized problem and ran out of time to deal with the overall codes. I don't know what the map looks like for a triple. My guess is that it is a whole lot smoother than the codes that were loaded in TT600s, since my understanding is that triples work nearly flawlessly from the factory.

Good question... anyone out there have a 'before' jpg of the map in an 02+ S3?

I'd love to see it. I don't have a fancey $150 cable yet

Still aching from the recent transaction - the wallet that is.
