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

[Rasher]

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.

My point is why can they not just alter the fuelling within the Flash :question:

Take your "Bunch of fuel" added via the pwoer commander and write that into the map on the ECU.

I appreciatte a custom map is going to be better, but on my old ZX14R I removed the secondary flies, the Dynojet map added 40% fuel in some places - on a downloadable map that worked OK - my custom map was not that different to the downloaded map I started with, I later had a custom map flashed to the ECU that was able to get the fuelling spot-on and threw the power commander away (well sold it)

As long as my bike has no restrictions and no issues (i.e. no surging) I will be 100% happy - even if a Power Commander may get a slightly better feel or a shade more power, gives me something to do when I get bored with it again ::013::

My two cents, more than you asked, but I needed to include it for it to make sense

Listing your mods if you mail your ECU to be flashed will help them get you in the 'ballpark', and that is enough for most people. For lack of a better explanation, you are simply taking a generic fuel map they provide based off their best comparison of other bikes they've worked on and sticking it on your ECU. You probably know this, but some might not.


I look at ECU reflashing as more of a way to "unlock" features that are limited/restricted by default from the factory. I don't look at it as a replacement for custom fuel mapping, though. That's pretty much the opinion of most I've read on the matter.


Unlock the ECU and take whatever ballpark fuel maps they can offer, then go put it on the dyno and get custom map. If the vendor that does the ECUnleashed flash dyno's the bike with you being there, and can flash the custom map directly to the ECU, one could go that route. Again, this is assuming you lived locally, or if not, use a piggy-back tuner like a Bazzaz or a Powercommander if not local, and could flash the custom map right onto the ECU based off your desired map you provide. But, maybe this would incur an extra cost, I'm not sure, since you'd be deviating from the norm and probably adding a bit more time to the whole process...


I prefer the fuel management piggy-back route anyway since it's easier to do follow-up modifications with the AutoTune 6, 8, 12 months down the road if you need to.

Exactly what I am looking for (initially at least) ::008::

Every vehicle on the planet effectively comes with a "ballpark" map, and your spot on, it is enough for most people, not like stock vehicles surge or run totally shite (if you ignore the odd stumble ) and a ballpark map that works with my mods would be perfectly acceptable.

My initial issue was only the restrictions, but then I saw others with great gains from losing the cats, Blue Eyes and Spasm were the main offenders, but I was not going to bother - until some used headers came my way at less than half price, then I immediately noticed the more willing pickup and extra top end zap.

If the Unleashed map turns out to be "in the ballpark" I will be extremely happy, if it is truly awful I will have to decide between splashing out for a Power Commander or going back to stock pipes and asking for the "stock" Flash to be installed, but in all honesty I am at the point now where I would probably just leave it alone until the winter and then fit a Power Commander for next season - just too many people so happy with a full exhaust system + Power Commander to ignore.

OK, the flash is right on the edge of the Ballpark for my modifications, still needs a tiny refinement for fuelling at very low revs / loads, but overall it is very good, full story here...

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...

Michael,

Just to re-request this question since it's getting diluted again with modification discussion. Just want to find out the basic difference between Gen-1 and Gen-2 for a stock bike.

Thanks in advance.

Basic differences between the two are new fuel maps, smoother throttle response, and new ignition maps. If you have a gen 1 flash and a PC setup, you probably do not need to upgrade although the offer is available to everyone who purchased a Gen 1 flash.

Stop that already! I have a Power Commander and catless headers on the shelf and you're gonna be the cause of me neglecting my homework 8)

Has anyone gotten the new flash back from ECUnleashed, yet, and if so, how's it feel?

 

[Sup-Ten]

California, I got mine back from AF1 with the gen 2 flash week before last. I believe mine was first Ed had done with new flash. I never had first flash so can't compare but I'd be up for a meet and let you check it out to compare if you like. I've got Pcv, auto tune, header and Akra.

In practical terms how would the difference between Gen 1 and Gen 2 feel to the rider? Aside from smoother throttle response. I'm sure many of us have just done the flash without the PVC and Autotune and would like to know if there is sufficient change to warrant removing the ECM and shipping it etc. I can only speak for myself, but I am willing to go through the time and expense if there are real, tangible improvements. If the changes are marginal compared to Gen 1 and the gen 2 is better suited for those who have yet to flash, I would appreciate an honest review which tells me so. I'm looking forward to a side by side comparison by someone who is an unbiased third party.

That is well said. I am in the same group.

Michael, can you describe for us? No power commander here...

Until he chimes in, here's what I feel you'd notice most on a bone stock bike.

1) Decreased engine braking on decel - instant gratification/feedback. In traffic one might like engine braking, but I'd rather it be lessened when going into turns. Let's me be in more control going into a hard corner and not guess how much the engine is going to slow me down turning in

2) Without seeing the stock AFR's in the ECU vice flashed ECU maps it's hard to definitively tell you how much power increase you'll feel. But, no doubt about it, you will feel an increase in power. Even if it's ~5-6% increase in power, that's definitely enough of a bump on a bike that you'll be smiling no doubt when you get on it hard. The stock AFR's are super lean, and my guess is the ECUnleashed maps richen it up a little bit which will undoubtedly (in this case) increase HP/torque across the RPM/throttle range.

3) eliminated power restrictions in 1-3. not hard to get TCS to flash WOT in 2nd & 3rd now even on a stock bike...TCS off and you'll be on one wheel easy

hope that helps some...

As above ::008::

Mine with the Gen2 Flash feels like it has a Turbo fitted (but without the lag) it now pulls SOOO HARD from 3k - 5k on part throttle, obviously in lower gears on a stock bike a lot will be down to the fly restrictions being lifted, but I already had the clutch mod.

My guess is just like Karson mentioned, the richer running in the closed loop area has massively improved the power, or more importantly you do not need to wrestle the throttle right around to get to the power, the dyno graph shows fairly modest gains in this region (5% or so) but the impression I get is using the typical 20%-50% throttle openings I use in "normal" riding the bike feels like it has more like 30% or 40% more power - makes it far easier and nicer to ride.

Even in top it pulls like a bastard from 3k ::015::I seem to use a lot less revs now, probably shifting 500 - 1000 rpm earlier, and it feels like I am going faster at the same time.


I know much is made of the stumble, mine had this stock, the CJM sorted it, and the Flash removes it as well in Sport mode, but I am not convinced it is not still present in Touring mode, although I got bored of touring mode within 3 minutes and abandoned any further tests, can't see me ever using it with the exception of slippy off-road conditions which I doubt I would ever encounter.

A couple of days commuting has convinced me this was money well spent ::008::

 

[triman11427]

I've felt these same improvements going from stock to Gen 1. Well worth the change. I'm asking if its a significant change if you've already got a gen 1 flash to go to gen 2? Has anyone done a comparison between the 2? I'm talking real life, not hypotheticals.

You had your ECU flashed locally, correct? I may end up sending my Euro spec ECU stateside, but am a bit concerned about possible differences. I imagine all of the pinouts, with the exception of the immobilizer, are the same, but being sure about that would put me more at ease.

 

[Mark R.]

I am a little ticked off at ECU Unleashed. I sent mine overnight last Monday, with a pre-paid overnight return label, and as of this morning, the Fedex tracking number shows that it has not been dropped off for return. Karson sent his later than me, and presumably has his back now, so I am getting kind of upset with them.

Does anyone have a number or email? I PM'ed them from the forum two days ago, and have not gotten a response as of yet.
