    I did post this on PCV plus add on's in Mods, Upgrades, Accessories and Products but that thread seems to of dried up.. does any one know anything about this?

    So I have also ordered my PCV & k&N filter & going in to have the custom map done.

    They were also talking about "flashing" (think that's right) a US company that allows you to reprogramme the ECU allowing even better tuning & removing any limits some bikes might have in certain gears. Have any of you heard about this? I'm going to go do some googleing.... Not having it done would just like to learn more. Does the Blades ECU limit the power in any gears?

    I beleive once 186mph is reached it no go any faster............so there must be limit in the ECU somewhere. We used to get over this with the Busa's by fitting a "Tre" which fooled the ECU into thinking it was not in top gear and the speedo was less than 186mph.

    Mapping the ECU is always a nice option as no other electronics are involved, now depending on the ECU and software used will determine the number of throttle positions and increments of RPM that can be mapped out, on Ducati for example the number if throttle positions and RPM brakes is as many as you like, so over say PCV that has 10 throttle positions and each 250 RPM that can be mapped Ducati ECUs can have as many as the programmer likes, I say programmer as not any old Joe can understand the raw code of the ECU unlike PCV that has a simple interface anyone can see and map etc.
    There are packages like TuneBoy that let a person connect to a stock ECU and it shows the info in plane English so you can understand the raw code that the ECU runs, so fan trips, mapping and much more can be changed.. The BIG advantage of PCV is that all dyno centres can connect to it and map it unlike other options around. Also PCV can even be read and backed up with a standard PC and the software they supply, so once mapped you can save it in case your PCV fails!
    Im all for mapping the stock ECU but the questions are how fine is the mapping and how far do you have to go to get it done...

    RE-mapping the ECU or 'Flashing' is the most common way of tuning car engines, especially Diesels.

    A complete re-map of the engines ECU generally gives a better result than using a 'Tuning Box' such as a PCV in a Bikes case.

    Advantages of a 'Tuning Box' is the ECU is left un-touched and the 'Box' can be removed by the end user and the Bike or Car put back to stock with no involvement from the initial installer who will have used a Laptop and specific programme etc to do the work in the first place.

    I've had my Merc Diesel Sport's ECU re-mapped and although it was a 155mph car already it flies now.
    The best jobs are specific to the engine and use a Dyno to achieve this.
    A lot of modern Cars like the Merc have a special 'Dyno' mode that needs accessing and setting via the OBD diagnostics port to disable the vehicles safety features such as traction control etc.
    Most re-maps will also disable the usual 155mph limiter set by the OEM.

    And a note with car mapping is some will LOCK the ECU so no one else can map it, as done by a guy who I know who maps skylines, a bit of a con I think!

    Thanks for the info guys..
    It's very interesting all this!
    I can see the advantage of remapping the ECU and not having a piggy back bit of kit plugged into it.
    Would an advantage of having the ECU remapped be still having the 02 sensor functioning, allowing the bike to compensate for atmospheric pressure? Surely if I have my bike mapped here with a 02 eliminator to get the full control of the whole rev range, then ride over to the alps the fuleing would be out because of the altitude? or am I wrong?

    Forget any OEM lambda sensors as they are all narrow, PCVs Autotune uses a BOSH wideband sensor the same as the dyno, and yes it will self map all the time, high, low, damp, dry and so on... I tested mine on the dyno and it's spot on!

    That's a trick bit of kit!
    Guess you would need that remapping or know how to do it yourself to get the best out of it. It is more than a PCV but it gives you allot more toys...

    Ah I see so is an autotune the way to go and not have a dyno session?
    I guess the autotune would adjust say if you ran with baffle in or out too...

    Thanks for the info chaps this is interesting...

    You need to understand Autotune, I did a write up on how it works on here, in short if used with a custom map you need to do little, if mapping the bike with just AT then you have your work cut out, if I had a propper keyboard right now I'd write the whys and how's etc.. have a search...

    Basically yes it's the nuts and will trim the AFR real time all the time! I love it and it works 100% just set a target AFR like 13.2:1 and AT will trim to it.

    Thanks arthurbikemad I'll search out your write up.
    I have just read the blurb on the Dynojet website, as you said you just need to set a target a AF ratio and away it goes.

    I guess the last question would be spend a bit more on the autotune or get my custom maps done. or get the custom maps and then in the future I could run these with the autotune for what I guess would be the ultimate..

    Thanks for all the info..

    Yes custom map is a must! then AT to keep it in trim, if touring with changing sea level then it will come into its own.

    Just read your other thread thanks for all the info. Is this what you do as a day job?

    I'll get my custom map done and look at an autotune once I've saved my pennies again!!

    Back to the ECU again not that I need any more power in the lower gears but does the Blade's ECU limit the power/revs in any gear I know some bikes & cars do. I haven't noticed it doing anything I guess this is only fixable by getting into the ECU.

    Re flashing the ecu is a common practice for the ZZR14 i have. Mine can go to around 215-220bhp when reflashed and they also tweak the traction control system at the same time. I would much rather do the ecu than paying Mr Dyno to strap a PC5 on.

    not 100% sure but i know on a lot of earlier thou's (04+) including gixxers+zx10r's the timing was retarded in lower gears to basically stop you flipping the bike in the 1st couple of gears,this is where the TRE (that was mentioned earlier) comes in,it fools the ECU into thinking it's in 4th gear all the time so gives full fueling and also takes away the limiter (but not sure if this is applicable to all bikes,deffo the kwaks+gixxers)

    Sorry, I come for more of a car tuning background. Does this mean that the Auto tune acts like a knock sensor would? I.e. it detects what the engine is doing and cuts the current map because it is sensing detonation at levels that aren't harmful to the engine?

    There's no way I need more power in any gear or want to find out if I can flip my bike in first gear! I'm sure I could do that trying a stand up wheelie.... But it's interesting to find out about this kind of thing (well I think so!)

    I'd head Gixxers Busa & B King thingi limit power in certain gears, hats what made me ask really, Do Honda do the same. Although as the blade is the only bike without any electronic aids maybe they don't, as the chassis is so good. Or they have just hidden it in the ECU maps.
