I got FLASHED Monday morning.

I'm not sure, but it looks way too lean to me.

But too lean can be fixed. Fuel cut like that is a show stopper.

[whittlebeast]

The fuel cut is still there on the 07 ECU from ECUnleashed. Fuel turns back on at 7000 just like my 08 and 10 Euro ECU.

You mean the ECUnleashed tune is on the right?

Previous plots are a good example of using MAP vs TPS for tuning. Pretty obvious why MAP is your choice.

I'll have fun tuning

Sorry, I got that backwards. I fixed my post.

So after all this posturing and all the hoopla, fuel cut is still there....

[Super Googan]

So lets summarize, they advertise getting rid of the exup codes and fuel cut on the website ( but don't ) and the flashed ecu is looking way too lean in big areas.


Maybe they managed to get the timing right and that's why people are " feeling" that the bikes more responsive.
Increased timing may give the bike more snap down low and give the illusion that its tuned well.

Any dyno charts yet ???????

[SoCalFZRider]

Have been adding fuel on the PCIII from looking at Beast's scatter plots. Started with ~1/2 AFR in the cruising range. From what I see here I need to bump that up and expand the range for the next road trial.

No dyno charts yet.

[KBay84]

I have a stock 2010, and the cut & snap around common street corners is nasty. Not to mention if I actually get into a *real* corner on a twistie @ speed. I see the graphs that Whittlebeast has put up, and to me they look like the graphics from "Twister". Give me something that tells me that this is a good deal for my bone stock bike.

Outside of that, I'm faced with a shyte load of mods and FCE et al......

If you tune to a target AFR you may interpret it is lean, but most of the better tuning shops don't use AFR, they use the notion of "complete combustion." In other words at a given setting, it the bike burning all of the fuel. With that method AFR is not even considered, and is a moot point, as the AFR may very widely. The bottom line is how does the bike perform.

[whittlebeast]

For all of you guys still attempting to tune a bike TPS based, here is the screen shot of TPS vs RPM.

The reason that the dots are relatively scrambles on the right plot below about 12% throttle is that in those areas, fueling is not a function of TPS and is always going to be a fight.



ECUnleashed is on the left. My tune is on the right.

Have fun tuning

[whittlebeast]

I just noticed that they set the bike up quite a bit leaner in fourth gear than 6th. I wonder why? Yamaha is set up fairly symmetric per gear.

Wouldn't " complete combustion " give a pretty consistent AFR ??? I could see if we were talking about a small variance in AFR but that chart looks WAY lean in quite a few large areas.

You always have "complete combustion" at a lean AFR because the ratio of air to fuel . Even lean to the point of excess heat and damage.

The only time you would not have " complete combustion " would be too rich.( unburnt fuel )
Maybe what your trying to say and what I'm interpreting are different. Can you explain it another way ??



" The bottom line is how does the bike perform "

True........thing is butt dynos lie I'm starting to suspect the butt dynos are being fooled by increased timing and maybe the flies opening quicker that gives the bike some extra snap down low. A few people have mentioned the torque and response from a dead stop or part throttle.
Compared to before the flash.

Many people have reported great success with Ivans mods and maps and his maps are generally considered on the rich side when viewing AFR or compared to other maps.

Just for the record I haven't spent one penny with Ivan.

My point is his maps tend to look to be on the rich side with an 02 sensor checking AFR and the vast majority have loved his maps. ( and it seems to be a BIG majority )
The flashed ECU is looking very lean but we only have a few guys that have given a review and one of them sounds like he has an issue with a flat spot or bog in second gear.
I'm betting that problem area is too lean after looking at those graphs. That BIG lean area looks to be right in the rpm range where his issue is in second gear.

I'm still jealous of that Tuono

EDIT : I SEE THE FLASHED ECU WHITTLEBEAST TESTED HAD THE FLIES TIED OPEN.........is the flash made for a bike with open flies ? That big lean area MAY be because the flies are tied open. Any thoughts people ?

[Super Googan]

Whittlebeast .........The bike with the flashed ECU had the flies tied open.

The flash is for a bike with open flies ? I wonder if that contributes to the big lean spot ????

[whittlebeast]

My tune did not really change all that much going from normal flies to tied flies. Neither did the acceleration. The only real change is how predictable and consistent the snapping the throttle got.

On the later bikes, that is just a tuning issue and can be tuned out. Fuel cut on the later bikes is 7000 and above. Anything you feel below 7000 is something else.

[jdc606]

As for AFR not important but rather how the bike performs...my old boss drag raced snowmobiles in his younger years and had a very good winning record. His secret to success?... ran so lean he would hole a piston nearly every run. "Lean makes power...thin to win", he would say.
I use a wideband plugged into the same spot Beast gets his readings from and am using CASquires map. Squire said his map was developed using wideband and eddy current gas analyzer... all I know is it gives me the AF I'm looking for and makes my FZ run great. Almost always reading .90-.91 lambda (13.33 A/F)

That ECU plot is disappointing...

[whittlebeast]

My latest midrange target AFRs are set to 13.5 That is really close to what jdc606 is shooting for.

I like 12.5 to 13 AFR at 15% throttle or above. Get out of that range and I start leaning on the tune. I work with averages of say 30 pulls up thru the powerband. The patterns get far easier to see with lots of data.

Wrong as usual........


4500 rpm on all years of this bike....
(I verified this with a simple testlight on a 2010 model)

Ivan - Nice

I like the idea of flashing but the way it is being used, would be like making a map for a stock bike and then using the PC3 map for all bikes no matter what mods, of course the fueling is wrong.

Not getting rid of the fuel cut and saying it does, is something else all together.

Beast -You are smarter then I, but I now know that your readings are jacked because there is alot of fueling changes to be made once the flies come out.

It will have to be like Tune ECU for Triumph so you can download maps in yourself with a $20 cable or the dyno man can put the changes in the ECU. It needs to be just like the PC3 but without it. Right now these super generic tunes and claims are not cutting it yet.
