ECUnleashed Gen 2 reflash- What is does and how to get it

And, is this flash suitable for non-US ECUs?

I would be interested in hearing from anyone that gets this GEN2 flash and actually can tell it makes a difference, especially MPG.

I'll help you out. I sent mine in yesterday. Waiting to get confirmation on a couple questions I asked when I filled out their online form and the restricted-site dealer form fred earlier referred to.

What I plan on doing is some back to back tests with 0's in my Power Commander maps, letting the ECU handle fueling completely, then putting my last known good PCV map back in and monitoring again. Of course, I'll try my best to mirror riding condition/gas stations/etc... best I can.

Hey guys I just wanted to give you a quick update, I was involved in an accident over the weekend (06 FZ-6) and will be answering everyone's questions tonight or tomorrow morning. We appreciate all of the support and patience.

Hope you heal quick. I sent my ecu in for the Gen 2 reflash and wouldn't want you to miss it. ;D

FYI - I've started a results thread since some folks have either gotten there's back already, or are en route to ECUnleashed as I type. Rather than clog up this thread with results and post-reflash experiences, take a look here:

I've also researched a bit of the outstanding questions by Rasher and tried to link to some sites who asked similar questions. Although, final clarification would be good from Michael...

Thanks, and your right, I would like clarification, I am willing to be an early adopter of this Flash, hand over my money to ECU Unleashed and don't think it is too much to ask to be told what I will be getting for my money, especially as Michael has contradicted himself a bit and failed to answer questions he said he was going to reply to.

Yes, we can flash any market ECU

Rasher said:

Sorry to hear about your accident.

I think the two biggest questions / areas of confusion are:

1. Are the O2 sensors utilised

2. What are the effects of a Gen2 Flash on a bike with a Power Commander :question:

a. Would the PC map need altering if the Flash is updated on a bike with a power commander

b. Could the Power Commander be removed with little / no disadvantage if upgrading to a Gen2 Flash

c. Or for people without any other mods does the Gen2 Flash pretty much eliminate any "need" for a power commander

Many thanks

I'm going to try to clarify this without adding more confusion.
1. Yes, the O2 sensors are utilized unless removed.
2.A- ALL bikes with an aftermarket fuel controller, be it a PCV or Bazzaz, etc MUST be set to a ZERO map after the reflash. Because we change the ignition and fuel maps inside the ECU the 'stock' reference settings these maps use to adjust fuel are completely incorrect and will cause the bike to run incorrectly. Your fuel controller will still work after the reflash, but you will need a totally new map created by a tuner.
B.- Yes, you could remove the PC after the reflash, although it is not necessary. I would personally leave it installed so that the bike could be fine tuned after the reflash.
C. Yes as we do correct fueling with the flash



Significant improvements to the throttle response in "S" mode maps
1) Greater fuel efficiency in "S" mode maps
2) "T" mode mapping remains stock but we made slight adjustments to the AFR (Air/Fuel Ratio) in 5th and 6th gear producing a value of 13:1 as opposed to 12.7:1(factory)
3) Better advance maps over both cylinders 1 and 2
4) Fully compensated for the closed loop routine below 5k rpm
I'm under the impression that #'s 1,2,4 sound as if they're strictly fueling changes. Correct? I can see where that's a good update for folks if they won't be running a 3rd party fuel management system like a Power Commander or Bazzaz.
Can you elaborate a bit more on #3? Are you referring to timing map changes? If so, what scenarios would it be "better" (i.e. what does better mean?)
Thanks in advance.

Yes, number 3 refers to ignition timing changes. Better in this case meaning smoother ignition maps for both cylinders.


Surely if they are using the sensor I cannot remove it, also are they not just narrow band sensors in which case they cannot be utilized regardless of how you alter the mapping.
Please see the attachment** for this. They are not narrow band sensors as you can see they give a voltage reading all the way through the power band. What we do is alter the 'base' fuel maps, from there the ECU will use the O2 sensor to make minor fueling changes depending on the sensor readings, in this way our reflash utilizes the O2 sensors. IF you have removed the O2 sensor, the ECU will just use our altered 'base' maps without modification. These maps are still much smoother and will create more power from then the stock maps but because the bike still runs without the O2 sensor, we do say they are not required although they are recommended. We do not remove the functionality of the O2 sensor in the reflash if your bike is not equipped, we only disable the dash code which leaves the option to install one later a possibility.


**The attachment is a 5th gear run from the gen1 flash and is only for reference on the O2 sensor readings.

Thank you ever so much for the clarity ::008::

I have booked in for a Gen2 Flash this Saturday ::26::

As the O2 sensor will do a useful job I will leave mine in place, nice to know the entire closed loop area has been optimised as I am sure this is the root of all evil on modern motorcycles as they leave the factory.

I bet most of us spend well over half our time in this area of the mapping.

NO FREAKING WAY. Michael, you've done well if you sold him Looking forward to comparing experiences, Robert... You'll have yours flashed and back in the bike before mine...

Shipped mine via UPS from IL today. $36 including a prepaid return shipping label (insured for $1,000).

What can brown do for you, my butt! Mine was ~$60 shipped UPS ground with a prepaid label inside. And, insured at $1,000. You must have the hook-up with Mr. Brown, Fred. ::008::

The more I think about it, probably because I used a UPS Store/renamed Mailboxes, etc. outlet...

Yeah, those UPS store/Mailbox stores have to make a profit for their efforts, I guess. I am able to box up my own shipments and ship thru my dealer and get the employee rate. Still, UPS' rates for insurance have sure gone up in the last few years.

Michael,
I have a small problem. I had the flash done on my bike through AF1 racing when they first came out. I have recently sold the bike(most of the guys on here will testify to that lol), and the new owner would like to have the new Gen ll flash. I have all my info to give him and would like to know if this will be a problem.
Thanks

Michael,

What is actual drop dead date to get ECU reflashed for the cost of shipping charges? I am going to be out town and will be unable to pull my ECU and ship before the first full week of May.

Thanks!

When I came to, my wife (a nurse) said I just feinted.

If the bike is rock stock except that it has the ECUnleashed Gen-1 re-flash, can you give a brief outline of the improvements that the Gen-2 re-flash will provide? This will help clarify for those of us that do not have all the additional mods that are being discussed.

Thanks in advance...

Confirmed with UPS online tracking that my ECU will be there today. Hoping that they got my email that I'd be glad to pay for 1-day shipping back to me if I can give them my CC info and they can throw away my prepaid ground label.


Weather's just too nice and I cannot wait another week! Hot damn! ::018::

No sympathy from me. If I can't ride, then.....

Seeing as Steve is as far as I am aware the only Gen2 Flash reporting back I am a bit dissapointed to see it is still not quite right:-

Stevek said:

OK, so I've now done 1000 miles since the updated flash was installed. Has it eliminated the stumble at 2000 rpm, sadly no - but it's better, less violent and much less infrequent, but it's still there, annoying. Now the good stuff, this is how the XT should have been mapped out of the factory. The motor is now actually fun to spin with significantly more power throughout the rev range and properly increased acceleration. I know that others will have their own viewpoints but I was ready to sell this bike as I simply couldn't live with the bland torque curve and woeful lack of grunt for a 1200cc lump. The current ECU flash transforms the bike, rice puddings no longer jostle me insolently as I do daily battle on the M25. I would recommend this mod although it shouldn't have been necessary in the first place and judging by the amount of interest mods like these have generated, many folks seem to feel the same.

If you have my set up (Akro - K&N - Arrow Headers) and the dreaded 2k surge, well the maps not quite there yet, for me at least - but, the flash does give the bike the kick up the ass it so badly needed and make it MUCH more fun to ride.

Not quite a happy ending though, today the bike suddenly refused to downshift or select neutral. At a standstill I can (after much jiggling) knock down a couple of gears but no neutral - a total bummer as I commute 120 miles a day and depend on the thing totally. The bike's just come out of its 20k (valve) service and my dealer's workshops stuffed up for a week. Hello Metropolitan line and laptop :-(

My guess is that if you really want a good setup with anything more than an end can your gonna need a Power Commander:-

simmons1 said:

I do have the same set up so this is a little disappointing to hear. I have a smooth idle and no surge at 2k at all with my Gen 1 Flash and PCV that adds a bunch of fuel at idle 1800 to 2200 RPMs.

What I don't understand is why ECU Unleashed cannot just get the data from the pwoer commander setups that work and update the fuel tables in their Flash to match :question:

I am still going ahead tomorrow, and as my setup is slightly less extreme with stock Air Filter and End can I am hoping it works better, I also wondered if what the bike really wants is a bit more back pressure than the Full Systems give, and maybe my slightly more restrictive stock can will help.

Either way I want the Flash to remove the restrictions in a "better" way than the clutch mod, I know for many the clutch mod does enough (and I am a fan) but I am sure the other improvements in the Flash will be of benefit, if I am still not 95% happy I will probably just save up for a Power Commander for next season - but still cannot see any reason why ECU Unleashed cannot get a flash that is good enough for these mods. Not looking for the perffect custom setup, just good enough - and think Unleashed should be able to get it to not surge.

And I truly believe that 5% nirvana you're looking for encompasses a lot of people with your specific mods, and the only way to overcome that is with a PCV if you can dyno tune your map, or PCV + AT if you don't dyno tune it.


For people without arrow headers, I would think the fuelling maps in the flash are good enough and would make that 5% not apparent as they're simply not increasing exhaust flow enough that it would warrant that need for a fuel management system on top of the flash.


The only way I feel the flash would not warrant a piggy back fuel controller if you have headers is if it was dyno developed specific to your bike...
