By european car (April '01, pg 148).

The tests were done an a DynoJet 248. I don't know anything about dynos, but it sounds like a "real" one.

 

I guess I will... but I have no basis for comparison

 

air/fuel mix? How does it adapt to different engine loads, conditions, temperatures, etc.? There is a reason why chips are expensive, there's a lot of programming involved. IT'S NOT JUST ABOUT BOOST. And I care what European Car says, their credibility is not real high. Besides, could you turn up the boost and get high hp on a dyno? Yes. Does this mean you have a good, driveable, reliable engine program? Hell no.

 

ancillary programming for turning up the boost. This requires a lot more programming and CANNOT ride piggyback on stock programming, because it replaces the stock programming.

 

Judging from the concensus of replies, you may be the first to report, firsthand, of the validity of the product. The way I see it, tuners like APR and GIAC had to start somewhere with their product line and someone had to step up and try it. If you want to avoid the flames, just email me your impressions. Thanks.

 

nah! a shakey hand will make it look real! =) dyno plotter pen

 

it's difficult to evaluate it properly. Since there's so much controversy around it, I will wait, and eventually someone will try it and then we'll know.

But, on paper, it looks good (too good to be true??)... For 250$, you get a boost gauge and you can manualy adjust how much boost you want, without any modification to the ECU! Geez, I want that!!

 

Ok, understand that I know little about the modern car systems, but I am a computer engineer and have pretty good intuition about complex systems in general and years of experience thinking creatively in their context.

I am going to attempt to show how this little box could do the same thing as a chip...

1) It reads in the data from the engine sensors
2) It is designed with knowledge of the stock chip behavior (all tuner companies know this stuff)
3) It contemplates the input from the engine sensors and resends them to manipulate the ECU to behave how it wants- it doesn't need to change mappings or timings- it just needs to know what those mappings are and how to invoke any given part of them using fake data.

So, I believe it can do all that a chip can do... just from a different location in the system.

It was designed using stock programming to do the same work as a chip and I believe, with my minimal knowledge of the fly-by-wire architecture, that it is possible to manipulate the ECU by "intelligently" faking sensor data.

I bet that a box like this could be programmed to emulate ANY chip and makes more sense architecturally to me than replacing the chip at all- someone should make one of these things that can be reprogrammed in situ. That would be really usefull, imagine being able to change your chip by simply downloading a program off a website! (assuming you trust the company offering the program).

I am going to buy this box. This technology makes sense to me.

I'd like to know how it turns out. Please post or email your impressions.

 

See my post "It makes sense".

I am pretty sure that with knowledge of the programming of the chip, one could program this "signal conditioner box" to get the chip program to work like any real "tuner chip"

It's just logical. The chip operates on sensor data and if you control the sensor data, you control the chip.
