ECU change to gain more HP

[Arthur]

Hi,
I'm new in this forum, but I'm glad to find out this interesting site.
I'm riding dt 300 since 2011, on 2013 I trade up to new one with ABS.
I have the multivar and my DT passed over 16000 KM.
I started a reaserch over a new ECU, or other non stock fuel managment system, didn't saw a lot of items on the internet.
As further looking I saw that "TK Turbojet FI fuel controller Lambda for Daelim, Honda, Kymco, Suzuki, Yamaha", and I am courios if someone has done some changes, or heard about modifying the stock ECU?
I really have a filling that the engine have much more power but something is stopping him, my geuss is the ECU.
What you guys think?
Thanks

Best case scenario, 0.5-1hp, not something you'd really feel.
Time to move on to a more powerful bike, you've squeezed a lot out of the DT already.
XC400 would be a good, but a small improvement.

Actually I don't think you quite right, I heard that you can gain 20% more HP and beyond that decrease fuel consumption.
The main reason that I'm thinking of that is the cost effective of the idea. Think of that with an extra 200$ you can upgrade your bike with the benefit of a 400cc one without spanding the addition high cost of buying one (also paying extra insurance rates).
I raise this post to really hear from someone professional about the risks, if there is, of such thing.
If I'm buying a costumize ECU, with plans that can be programmed and changed I don't see any reason of harming the engine.

If you re-map your ECU or change to a modified ECU with a stock or almost stock engine, you will not gain that much hp.   Remapping is done once your engine has been modified... cams, pistons, heads, etc.

I would like to add to this.

For engines that are producing so little power, tuning via a piggybak (Power Commander) or ECU mapping, even a 10% increase will only give u 2-3hp more.  That's minimal gains for the cost incurred.

But, having a custom tune/map would eliminate the factory map set to pass emissions, hence the removal of the flat spot giving better response, fuel consumption and ridability. 

Arthur, I really would be skeptical of a plug and play product that claims to give you 20% more HP, from a 300cc to 400cc scoot. Even if it can, I would be looking into upgrading your internals, fuel pump etc.

Extra power = more strain on the engine, it's not happening by the means of fairy dust.
Also, unless you have a turbo on that bike, 20% more power is laughable (and exactly
what a manufacturer of such a device would probably tell you).

I can't gain 6hp (DT's 20%) on my 100hp motorcycle with a ECU and a proper exhaust (and that's $1500 right there for both).

  The "TK Turbojet FI fuel controller Lambda for Daelim, Honda, Kymco, Suzuki, Yamaha"
is probably a resistor to fool your bike into thinking there is colder going into the engine
 than it really is.

  They claim all kinds of gains with those and it might make a little difference especially
if it is very lean from the factory.

  You probably won't find a reflash for our bikes as the market is too small for anyone to
develop one...

I believe power commander was available for DT or XC so you can do with your fueling whatever you want.
You'll end up gaining so little power that taking a dump before a ride will make a bigger difference,
and you'll probably end up with an increase in fuel consumption of up to 30-50%.

It makes a very small difference on sportbikes, and is mostly used for tuning out the flat spots etc, not
for big power gains.
