I´ll get a PCV - how should i start

Are you running the FCE as well or no?

I have the cut airbox, K&N filter, modded flies, AIS removed, 2Bros can and stock ECU. I hope to have a spare header to play with the gutted cat soon. Without the wideband and MAP addition, on a PC V, is your smoothed Stage III map going to be the prime choice? That was where I planned on starting after installing the unit.

For those maps that people are running WITH the FCE, how much of a difference is there in the maps?

I do not run an FCE. None of the bikes I tune have one.

If you have or will have a PC-v, do you still need or why would you need a FCE?
I would of thought the PC-v would solve all those fuel issues.

The PC will mask some of the fuel cut issues but it does not resolve the issue of fuel cut at all. Only an FCE will fully eliminate the fuel cut. The flashed ECU claims to but I think some of the serious tinkerers here are discovering that this is not fully the case.

Hey WB,

Does the Autotune sensor fit the existing hole in the FZ1?

Yes, but it is tight.

Well the sensor itself fits ok into the pipe. The biggest hassle is routing the wiring and securing the huge connector. You can see it here mounted to the Yosh header:

I'm confused on the benefit of FCE when you have a PCV. If fuel cut is occurring based on throttle position and rpm range, then why couldn't the PCV mapping be tailored to correct this fuel cut. The PCV mapping is both throttle position and rpm based. Help me understand why the FCE would still be needed.

Thanks,
Matt

That slip on header connection may prove to be a problem with a wideband. Air leaking in, is a nightmare.

Matt, I've already explained above. The PCV only *masks* the fuel cut. The fuel cut will always be there unless you install a device that will eliminate it. Even DynoJet themselves will tell you the very same thing as they will make no claim stating their device eliminates the fuel cut. A PC can tell the system to add or subtract fuel but when you are at the throttle/RPM range of fuel cut, the ECU will still shut down the injectors regardless of what you put for a value in the map.
 
hmm a little bit confused now , what to do :D

My PCV and (i allready ordered yesterday) Autotune will come this week.

But my great uncle ( i dont see him very often) is a specialist in tuning motorcycles. i just called him, couse i wanted him to ask if he could install my new braking lines, he told me that he has a dyno run and the complete dyno software at his shop and it would be no problem to tune my bike.

But what is now more intelligent ? let the autotune do its work or let my uncle do his job ? *help* :)
 
I've read the same, that the autotune isn't the optimal way to go and a custom tune is far better and remains more consistent. I'm going to start with a few Stage III maps from here and see which gives the butt-dyno the most noticeable difference. Perhaps, if I am inclined down the road, I'll find a good tuner and have a custom map made for me. I have a hard time justifying that cost though because if I make changes to the bike, that money is lost and needs to be paid out again for another map. Seems the people who share theirs have hit the majority of scenarios that will fit any list of mods in some fashion so I'll try theirs first.

You are fortunate to have family with this setup where you CAN custom tune and if there is any cost, I'm sure it's small. :D Go with the Uncle's offer and tune that bike specifically to your needs.
 
It is important to keep in mind that the setup that Mr Beast is advocating is not simply using the Autotune with the the PCV but also involves the LCD unit, data logging and MAP based tuning. The extra hardware for this is expensive stuff and most definitely has a steep learning curve for its use.

When Dynojet made the Autotune unit available for the GenII (to go with the PCV) it was used a number of forum members (mostly on the other forum) to attempt to generate the typcial TPS based maps with mixed if not predominantly poor results. Similar issues were reported with the R1 etc. Exhaust reversion messing with the sensors readings was one suggested reason for the problems. Most found that the Maps generated from Dyno testing and trial and error offered much better results. Basically, unless you are going to spend the $ and take the time to duplicate what Beast is doing, you are probably wasting your money with the Autotune.

There are most certainly many good maps available for just about any combination of mod package. There are also a large number of GenII riders happily riding around with the PC and TPS based maps. Beast's setup might be superior (I'm not sure how we will ever really know?) but its a lot of coin and it is complicated. . .

At this point I could do one without the digital display. No autotune setup will work with TPS based tuning at small throttle angles. The trick is making the tune MAP based below 12% throttle.

The LCD 200 is somewhat optional but is a huge help.

The wideband/autotune setup is mandatory. I like the Harley version if you can afford it and you have the LCD-200, as you get duel widebands.

The dyno is a $35000 option (or the typical moron that owns it that concentrates mostly on just cashing your checks) is an option I elect to pass on.

You no longer need the PLX MAP sensor as the stock one is better.
