Does anyone have any knowledge of a ECU flash for the FZ-07 ??
For what purpose? A re flash is only needed to change the fuel mapping. If that is what you wanted to do....a re flash isn't necessary.....only a fuel controller is needed ..which is cheaper and can be changed when you want to change it.

I am pretty new to modding motorcycles. I was talking to a friend who has been riding for a while and was talking with him about getting a power commander and he said to research about a ECU flash to flash whatever restrictions yamaha put on the bike from the factory in order to accomplish the same thing a power commander would accomplish for around $90 as apposed to the $250+ for the commander.
Hopefully that helps with more details in light of my original question.
However there may not be such a thing???

Ok but my question is WHY were you talking about getting a power commander for your FZ07. Does your FZ07 have fueling issues that need corrected? Or do you just want a power commander because it's cool to have one?

What you stated is only a small part of the possibilities of re-flashing an ECU. R.F. can also involve ignition timing, throttle plate openings (both the amount of opening and the timing involved in when they open) removing restrictions of the amount of opening, cruise control, top speed limiter removal if there is one, increasing the RPMs for the rev limiter, activating quick shifter functions, etc. And depending on who or what company is doing the R.F., it may or may not be more expensive than buying and installing a power commander/fuel controller module.

This is what my original question was guided to find out. I have just seen the maps from the power commander with exhaust and intake and would like to have my bike work at its optimum performance. I just exploring all avenues

The one true advantage to using a fuel controller instead of flashing the ECU is that you can change the mapping a lot easier with a fuel controller vs. a R.F......but, if the ECU is flashed properly, based on dyno testing for a particular exhaust, you aren't going to be changing the mapping anyway.....so it's kind of a moot point.

My FZ09 has had a R.F. and the difference between stock and R.F. is like night and day. Fueling was matched to the Arrow full system I'm running (without the D.B. killer installed). I also had the flash take care of the start up mode (it now defaults to "A" mode instead of "STD" on start up), and the fuel cutoff on closed throttle was disabled, which makes the bike's throttle a lot less touchy/jerky, when getting back on the throttle after closing it. The FZ09 come with a 132 MPH top speed limiter also, and that can be disabled, although at the time I had mine done, they had not figured out how to do that, so mine is still top speed limited, which doesn't really matter to me since the FZ is not my track bike Lots and lot of options for the flashing method vs. just a fuel controller, but you still have to weigh in the cost of each and determine which one of the methods will work best for you.

He's not asking about an FZ09...which we all know benefits immensely from a re flash. He is talking about his FZ07....which to my knowledge no one has reflashed yet. That's why I asked him why he wanted a re flash since it doesn't have any issues to fix.

Bob........my reading comprehension is at least average, so yes, I realize he isn't talking about the FZ09. You need to maybe re-read my post (#5) and see that there are in fact a few items mentioned in that paragraph that could pertain to the FZ07. If someone does figure out the ECU and could offer a cruise control setting like on the FZ09, that would be a nice addition. There may also be a possibility to raise the rev limiter if needed (probably for racing purposes) and I'm sure that some might be interested in quick shifter capabilities if it were available. Ignition timing and throttle plate openings might also be adjusted in a racing environment. Just because you think the only thing the flash would be useful for is fuel mapping, doesn't make it fact. No everyone buys an FZ (or any bike for that matter) just to ride it stock like it came from the manufacturer.

Vern...I get what you said...but no one has ever even mentioned getting an FZ07 re flashed. That's why I asked him WHY he wants to get a re flash....but have yet to receive any answer. It sounds to me like his buddy told him to get a re flash and now he wants one and doesn't know why. Did he change the exhaust and needs a re map....or is he dissatisfied with something that Yamaha designed into the CPU and he wants to change it? I'm just asking why. Many many FZ07 owners have purchased a fuel controller of some sort...but not one owner has seen the need to reflash the CPU and change any of the parameters in it like top end restriction....or fuel cut off...or anything else.

I understand what you are saying Bob. The FZ09, almost as soon as it came out was universally thought to be in need of something different for the throttle response "issues", thus a sense of urgency bubbled to the top pretty quickly. The FZ07 on the other hand seems to be on the other end of the spectrum and Yamaha got it "right" this time. Of course the 07 isn't a ride by wire setup like the 09 is, so the throttling issue is pretty much non-existent. Some of the things that I mentioned in regard to the 07 will likely be considered by the flash tuners, but I don't think there will be nearly as much urgency as there was with the 09. The 07 will fit in nicely to some of the amateur racing brackets and of course there are always a certain number of folks that will mod the bike just because they can.

I'm guessing that if a person's only interest is changing the fueling because of the addition of an after market, then currently (as far as I know) fuel controllers of various makes is the only logical answer. And when, someone finally breaks into the ECU and figures it out, that will become a viable option for fuel management also. Re-flashing an ECU doesn't always have to be a more expensive option. One of our supporting vendors on the FZ09 forum that I also moderate, will do a R.F. on the FZ09 ECU for $80 for some of the more basic stuff, which is a lot less expensive than adding a fuel controller type management system. Again, it's not something that you can hook a laptop up to and change the fueling without sending it back, but once it is spot on for a certain exhaust system, there really isn't much need to go back into it and make changes.

I've heard that for most bikes if you flash a stock bike you don't really get much from it. Maybe, smoother response etc but nothing that stands out.

I've heard if you flash one with a fuel controller and different pipes you can get more benefits from.
Seems like our yamaha -07 is pretty good out of the box so not sure if it would be worth doing. Anyway, would like to see if someone else has done this and what they think... I'm pretty satisfied with mine stock so now it's a non issue for me....

I am a part of a facebook page for fz07 riders and this site was posted. I plan on sending my ecu in as soon as i get my yoshi exhaust installed. The main reason i want to flash is to turn off the Injector Decel cut (which causes the bike to have a slightly jerky feeling when rolling all the way off the throttle and then opening it back up again at slow speeds) and to get an overall map for the exhaust i am going to add.

Not sure if we are allowed to post links or not...if not i apologize and will remove the post and post the link correctly.

A ECU reflash on this bike by 2wheeldynoworks will really wake the bike up in stock trim...this is the best bang for buck performance mod you can do next to the suspension...they will remove the speed limiter...adjust the fan on/off cycle to 200° instead of like 220°...tweak the timing and fuel injector pluses...remove the bike dirt like engine braking that is not needed...etc...a power commander just tweaks the fuel tabs...

vcyclenut is $180 and 2wheeldynoworks is $319. Wonder what the difference is?

The injector decal cut and engine braking is annoying to me.

From what I could read on the internet... 2wheel dyno is the one to go with...they do more ECU tweaking than the 180$ option...you get what you pay for...

Paul....you don't need a re flash with the Akra you just bought from me. Install the Akra when you get it..and I guarantee stock engine braking will be severely reduced.....and there will be no hesitation on the on and off throttle.

2wheeldynoworks is an awesome company. had my ecu back to me in less than a week. with my DNA stage 2 filter w/ intake, yoshi exhaust and r6 throttle tube mod the bike feels COMPLETELY different. I highly recommend them.

WHY ????

a good flash can only be built by someone with an thorough knowledge of (in this case) the specific bike and at least, a basic knowledge of how things work. If you use a PC, you know what a flash is; very time a BIOS/UEFI is updated....Think of flashing is an improvement to brain of your computer. Can you imagine the complexity involved in writing a new BIOS/UEFI code?

Auto makers frequently update ECU/ECMs on their cars as improvements are recognized and fixes are needed. For internal combustion engines, emission standards play a big part in ECU control, and it appears the e-standards are responsible for conditions that may be good from a emissions control perspective, but not from a performance perspective.
Sellers of motorycle materal know that bikers today have more money than sense. I guess if you own a company and feed your family with the profit you make; you take what you can get - and let the buyer beware.
Someone hear already said it: for most internal combustion engines, a good flash will provide the best of what an engine is capable of. Don't look for miracles. (that is what Tune-Ups are for.) Yamaha makes good bikes, imo. The engineers that design these bikes know what they are doing, so do the folks that run the company - (i am talking about Yamaha here) Flashing an complicated existing design is not for the un-initiated.

To sum it up, too many of us, including me, tend to talk about things we don't know much about as if we did. That's ok around the campfire, but not on a forum. Some of us are actually looking for legitimate knowledge when we ask a question. Ride-On!

Just got my ECU back from 2 wheeldynoworks and it was well worth the cost imo. They do way more than just fix the fueling if you've changed your exhaust. Went through each gear and cylinder removed timing retards. Smoothed out the on/off throttle transition as well, just to name a few. Experiencing the results first hand would make a believer out of even the most skeptical (BOB)
