spoke to my local tuner yesterday. he said there will be a ECU crack releasing in few weeks. I asked do I still need pcv? he said this crack will be better than pcv.
cost $720 for full tune. (Brisbane QLD, AUSTRALIA)

I saw the title and first thought you had a cracked ECU phew :)

ECU crack...never heard of a ECU crack, its probably just a ecu flash tune
Yep, the 'crack' is referring to cracking the code to allow the new map to be used. Pleased with my re-flash... I still don't fully understand the wizardry that went on, but it works so that's all that really matters!

Is a re-flash better better than a Powercommander.V ?... :confused:

Ha ha, well ain't that the million dollar question!

The bike before me in the queue for the dyno was an S1000R which was in having it's PCV removed and the EUC remapped. The owner seemed very pleased with it's performance post remap.

PCV alters the fueling by taking control of the injectors while reading the engine speed and throttle position. It is simple enough to install and only needs specialist help if you want a custom map. It's also easy to remove and sell when you change bikes, so it will retain some value. Remapping is permanent, and requires specialist help, once you've paid for it you're not getting anything back! It also (so I'm lead to believe) gives a lot more tuning possibilities because it has access to the full EFI system and sensors (MAF sensor for example). As I've said before, I really don't have any expert knowledge in this area, so I can only go on what I've been told from various sources... all of which are likely to be highly biased towards one way or the other!

I had a PCV on my CB1000R and actually made money.... I bought it at six months old and sold it 3 years later for more than I paid for it! It worked well, but for me my GSX-S deserved a more permanent solution to it's horrible throttle response which is when I started to research the remap route. The rest of the story is here >> http://www.gsxs1000.org/forum/suzuki-gsxs-1000-maintenance/19954-remap.html

Thanks for the info Martin... I did infact keep tabs on your Remap escapades.. I've got a PC-V winging it's way from the USA that I managed to get for £200, just hoping that's going to be as good as your remap.. :)

PCV is super easy to work with. People like you and I can use them. If you knew my computer skill level, you would realize how amazing this is.

Ecu's dont just use one map. Especially once you start factoring in traction control. There will be hundreds, if not thousands of different parameters a tuner can deal with if they can crack that ecu and be able to make changes. If a person can get into the ecu, it allows timing changes, rev limit changes. Anything the ecu controls is fair game.

Better? For sure...IF you know what you are doing. If the tuner knows what he is doing, the ecu reflash offers more options.

Warranty? Of course it will void your warranty. Thats not to say if a brake caliper goes bad, they wont honor it, but if you had piston or valve damage, that ecu reflash will be blamed for it.

The problem with an ECU flash, is that it's a one-time deal (and in this case, it's very expensive). The whole beauty of the PCV is that once you understand fuelling, you can tweak it. The benefit, however, of an ECU reflash is that it opens up possibility of playing with other things, such as ignition timing, which you can't do with the PCV unless you pay extra for the ignition module.

What happens if you decide to change your exhaust or run an aftermarket air filter? Take the bike on a holiday high into the chilly mountains, or down to sea-level and ride across a desert in extreme heat? All these things will alter the required tune of an engine.

I personally prefer the re-tunability of a PCV, but each to their own.

Or you can have the best of both once woolich racing release their ecu box for the GSX-S which they are working on but had estimated wouldn't be out or a at least a month or so.

Its a box you buy that lets you flash the ECU. Think of the possibilities and the damage you could cause with careless tinkering! Fueling maps and ignition maps are what most people will play with. Good thing is like a PC V or a bazzaz you can remove it when you are finished and you are in control of settings with the woolich software. You can flash the original map's back in and put it all back to stock. Also takes up less space and doesn't introduce an host of extra connectors into your wiring. Can also do the same as a TRE just by copying the ignition maps from 6th gear into the first five gears ignition maps, change the red line (if you are that way inclined) and can also do exhaust valve delete without having to plug in an extra box to trick the ECU.

My understanding is that a re flash to the ECU will void warranty whereas A bolt on like PCv will not.
Of course a PC V will void the warranty. You just have to be smart enough to take it off before you put your bike in the garage for the claim;)

truth or nonsense....

One of our electronics team guys at work is incredibly talented. Genius level to the point where I really am not allowed to say what specific weapons he works with. He's also a car/motorcycle dude.

He said that the ecu reflash kits are fine, but you do want to avoid flashing it over and over. He said if you did this, you will eventually have problems. He would not give a specific number, but I wonder if this could be true?

He is not wrong. :)
But the number of times you can (re)flash the EPROM is rather high.
You would have to do little else than doing (re)flashes to reach that number, when it would be more wise to do dynopulls fiddling with traditional "piggyback" equipment to find the best fueling.
Then this knowledge could be use to alter fuel-maps and (re)flash/verify the tune.
But it is as stated earlier in the thread not only fuelling that can be altered.
It is ignition maps, removing limiters, disabling "unnecessary" electronics, altering STP-settings, adding QS support that makes (re)flashing ECU a good choise for those really wanting to "thinker" their bike.

It is more likely that a mistake(bad connection) or (more likely) a bad battery/voltage drop could "brick" the ECU during (re)flash, but the risk should be considered before going this route.

Personally I would prefer to work directly with the ECU (flash), but I would not hesitate to use PCV or Bazzazz if this could help in the "quest" to optimize my bike.

As of writing this, I had added a conventional QS (Translogic) and TRE (Healtech) on my GSX-S.
But hopefully Woolich will have a interface for the ECU soon.
The ECU looks physically similar (connectors) as the ECU for Gen2 Busa, B-King and the K5/K6 Gixxer.
It seems that some pins have been "disabled"(CPS), and some used for TC(secondary injectors?) compare to "donor" ECU's.

Cool, can you share with us the type of EPROM Suzuki use in our ECU's so we can look up the tech specs?

Seems strange that they would choose a device that needs to be erased by UV light before being reprogrammed.... I'm sure I didn't see the guy who remapped my bike go to such lengths.... Oh wait... there may be a reason for that :rolleyes:

Not trying to be pedantic here, but 'experts' who like to share their 'expert knowledge' on public forums aren't always what they profess to be.

No, but its easy to sit back and take shots at those who try to help, or discuss, is'nt it?

Jesus, Martin. Its winter. We need things to talk about. While many of us dont know much, its very obvious you know less, so why not participate and have some fun vs what you've become?
