Well i hate to start a tread like this but i have to...
Digital tuning is big here in Europe and their chip isnt so expensive....
Check it out

They are proved modds on Porsche's and others to get more juice out of your car and here is a start of a disscussion..I have sent them a mail asking if this chip will work with the Comptech SC -I have it.
Anyway will update when they answer...

Well to start, first let me point out that things like this are often no more than a gimmick, and "proven mods" are nothing but marketing fluff. Even dyno's are done "unscientifically" so they can be intentionally misleading.

We would need to know what exactly this does. Most "mods" that involve the word "chip" are useless. ESPECIALLY on the S2000. This is because our ECU is NOT programmable, and a "chip" simply won't do a damn thing.

The only way this chip would do something is if you could specifically dyno tune it and it lets you manually adjust a/f ratios yourself. However, if it's a piggy back like the VAFC (i doubt this "chip" is even a a/f controller anyways) eventually the ECU "learns" the VAFC and richens the mixture somewhat back to stock.

So the question is, does it allow YOU to program it, and how does it interface? Is it a replacement for our ECU? Is it a piggy back like the VAFC? if it's not even as advanced as allowing YOU to program and specifically tune your A/F, then it's nothing more than a gimmick and won't do a damn thing for your car.

 

Well as i understand it,depending on the aplication they change the original chip with theirs...or chip the ECU with adittional chip or they provide a piggy back chip for the Speciffic car and no there is no tuning done only Plug and play.
As far as expirience i have is with my brothers Land cruiser which is a 3 liter diesel with 166 hp and there is an official Toyota Chip -you can buy it TTE.de and it doesnt void warranty and it makes the Toyota a beast compared to before it makes it a 204 hp diesel....And its all legal...Adn its a piggy back type.No cutting involved.
But when it comes to the S2000?The most Build up NA engine in the World?
i know there was an official topspeed magazine Porsche Turbo in serbia done by Digital tuning and it was tested faster...
anyway what do i know...But you can check their site and they have a chip for the Pagani Zonda which isnt a cheap car and the Enzo Also?I wonder what can you get more from an Enzo but they say 33hp more and 16% torque more??And they say its legal...with EU regualtions and in most cases they claim drop in fuel consumption?
Anyway i can say its all not true when i think on the Toyota of my brother...I will wait and see what they say to my mail and inform back...
Cheers

Its also called sister or daughter carding.
It is the same thing that enjukuracing.com does on the Silvia ECU.

If the stock ECU(PLC/Chip) is non programmable what they usually do is unsolder the original chip and either replace it with a new chip that is programmable thought the factory Molex plugs through the serial or parallel port on your desktop or laptop computer.
OR
The other option is that they attach a new mother board to the original chip location.
The new board contains the new chip and usually a USB hook up that they will integrate into the original ECU case to give the appearance that the USB port is a factory thing.

By doing it this way all you factory sensors can be retained or disabled depends on you particular tuning needs.

Also for us here in the states we can still pull into the emissions testing and still pass OBD II connection test.

From what I have seen on my buddies Silvia project the re-chip and initial tune was $500US with any after tuning or re-flash costing $100. the problem is enjukuracing does not work an just any car. I am waiting on a response from enjukuracing to see if they are going to offer sister carding for the pre 06 S2000 ECUs

anyway

 

I agree and great comparison with the crack dealer....Made me laugh...
But still i cant imagine that there is place left to tune the Stock ECU on the Zonda or the Enzo on everything else left as it is...They are highly custom made cars and its little possible that a Tuning firm does the ECU job better...
Cheers

 

there are gains to be made from tuning, but nothing dramatic. the 06 ECU is programmable, and hondata is working on it right now. in fact, one of our members is their test car.

do not been fooles becasue they have chips for the ferrari and similar... think this way, do you think a ferrari owner o Zonda would pay to get a chipped ferrari?

I can said that I ahve chips for Mclaren F1, this is a free market.... but I bet you that I would never going to have to do it becuase I wont be asked to do it.

In Europe there is a lot of "chips" company, we even hace here a company that claims that his chips gives 300 hp to the S2000, in a magazine, at that time I was making 330 hp with the compresor, I asked them to prove it..... well I am still waiting.

There isnt miracles in Automotive aftermarket, sad but true, you pay what you get.

You can save some $$$ in some parts by buying knock off, spoon snorkel, costum exhaust but with the art of tunning never it requieres a lot the R&D experience and not all of them do it.

So the 06 ECU is programmable, wonder if it would work in the pre 06 cars???

 

no. you'd probably spend more than a turbo kit costs just to get an 06 ECU to work in an 00-05 S2k. with things like DBW, etc, you'd have to do a LOT of mods.
