FZ1 ECU Tuning

Very true I forgot they had to build the hardware to support it also. Hey least you know it should be right. Hope it works out well when you get it.

At this point this should have been free for ya, Pete!

It might be who knows? I haven't paid for anything yet.

And don't begin screaming for dyno plots any time soon. 1) I need to wait at least a month for a) money, b) cooler weather. We're a nice 95 now but I'd rather put the bike on they dyno when its 80 or cooler. It just get too damn hot above 80.

Ahh, cool then. I wouldn't have minded either to wait longer for something that is free :D
 
Piasini Engineering has been tuning MZR 2.3L DISI engines (as in the Mazdaspeed3) for some time now. There was a lot of skepticism initially about their remote (from Italy) tuning method, but I've seen a lot of subjectively positive reviews on mazdaspeedforums.org. For the price, they seem to offer significant performance gains. Thus far I haven't seen much in the way of data (dynos, logs, 1/4 miles) to back it up, though.

And being the tinkerer that I am, I would be hesitant to pay that much for something I can't make adjustments to. The only alternative I've seen is the Power Commander, which is likewise an incomplete solution---in that it is a piggyback device rather than an ECU flashing tool. Ideally we would have a tool like the Cobb AccessPort, which allows the end user to monitor and log the engine's own suite of sensors, make adjustments to fuel and timing maps, and reflash the ECU as desired.

I'll be staying tuned to this thread, though. The FZ1 ECU seems to be severly crippled, so as far as ECU tuning options I say the more, the merrier.
 
Why not just build a new ECU that emulates a stock unit, but is fully adjustable? There might be some copyright infringements though unless open source maps are engineered.

It's not the hardware but the ability to hack into the Yamaha ECU and effect software changes. There are applications to do this for other brands of bikes. The easy part is hacking in, the hard part is what do you program it too?

I have two different applications for programming the Buell ECU. Unless you have access for many hours on a dyne it is pointless. The maps and functionality options are very complex.

Now if you have an R1 or R6 you can by a fully programmable race ECU. You can adjust everything, its amazing, but it is very expensive, about $900.

If you can made the app more power to you.

Friday came and went... it's Monday and we are still all waiting with anticipation.... What's up Top? Is it there? When will you be able to test and report back?
 
Ivan's post on FZ1OA

Ivan said:
You think that these guys are modifying all the fuel and timing tables in the ECU?? :laugh:

This would require an unbelieveable amount of time inside the ECU and also on the dyno.... we're talking hundreds of hours....

Most of them are screwing with the internal clocks in some way which creates undesirable side effects as well as a few positive ones.....
(Taking the easy way out and maximizing profits at the expense of doing it the right way)
For example, If they were actually in the timing tables, the fuel mixture would be un-affected..... Screwing with the internal clocks will advance the timing but will advance the fuel as well because both are dependent on the crank sensor's timing.

These facts are still true with this bike:

1) You will never get away from the Power Commander if you have any modifications.

2) Raising the rev-limit will not give any extra power as long as the stock cams are being used. This can also be done with the ignition module... which is needed anyway to get the timing right.

Raising the rev-limit is risky with the stock valve springs because Yamaha designed this motor to run within the rev range that it runs in..... Not higher.

3) Disabling fuel cut is very possible if they know where it is.... but is still way more expensive than using the FCE.

4) All the add-ons PC3/5, IM, FCE, can be sold separately when you are done with the bike and some of the money spent recovered..... Can't do that with a reflash.

If I were offering a reflash, there would be dyno charts and it would be done by changing the actual tables and the hundreds of hours would be spent on each bike that I offer something for.... just like I do now with the PC3/5, IM stuff that I offer.

If a good software becomes available someday that actually identifies the tables properly, I may actually offer a reflash service.

But for now, I wouldn't spend any money on it..... it's not being done right yet.

Its still interesting even if its not the norm for the way things can be done. I am mostly interested in fuel cut and power delievery in the first few gears. I think I would be awesome to get rid of the those portions of the programing without having to add anything to piggy back onto the system. Honestly if I had the time and money I would've paid to see if this works too.
 
Many car/truck/bike ECUs are programmed just like what Pete is having done here. Ivan wants people to believe that this is a poor method of improving performance which, in turn, is self-promoting his own products and services. My humble opinion but this makes for terrible marketing in my eyes. I'd have a vastly different opinion if Ivan had one in his hands and showed everyone charts that clearly depict why this is not a preferred method... in fact, I wish he would buy a modded ECU from these people and test it without mods, with mods and then compare with his own fully tuned FZ1 charts. I'd respect facts more than opinions. ;)

We will see what this change accomplishes when Pete can install, test and hopefully dyno and show us all. I'm not expecting explosive change but certainly a lot of improvements where the stock ECU falls flat. If they live up to their claims, it will be worth the money. For now, I'm just waiting for Pete to tell us and I KNOW he'll be 100% straight forward and honest with his findings. If it is horrible, he will tell us so. Since he knows 1st-hand what the '06 performed like with the stock ECU, this should prove whether the effort was worth the wait.
 
I for one am glad that Pete is taking this plunge. It is not like he doesn't already have a functional ECU in his bike. This is just his old spare. I can't think of a better circumstance to see if this is a viable alternative.

Don't put words in my mouth.... I have never inferred anything like what your trying to make people believe here. I never said it was/is a poor method.... I suggest you re-read everything that I wrote..... here and on the other board. :tup:

I have never read anything nice that you have written about me..... ever..... :)

Why does all the burden get thrown on to me ??.... Why don't you people hold the flashing company responsible for showing the gains? You all hold me responsible to prove the results that I claim..... What makes these people different??
If it was worth buying and testing at this time, I would have done it already.....

Eventually, flashing ECU's will become a good possibility for the most popular models (GSXR1000/ Hayabusa)..... I doubt it will be a great option for this bike because of the amount of time that needs to be spent to get it just right and not need the power commander.
