I take it no one here has ever added boost or added more boost then stock to a car before?
Because if so, they would know that you do not have to get the ECU reprogrammed or do a stand alone ECU.
All you have to do is simply add a piggyback computer that fools the stock ECU into thinking nothing is happening. They do this by intercepting the signals of the sensors and change them so the stock ECU thinks everything is normal.
This piggyback computer would also be responsible for adding the needed fuel via secondary fuel injectors or bigger replacement injectors, whenever boost is present.
Most piggybacks can be adjusted by the user via laptops or their own screen if they have one. Adjusting can be done on the dyno to monitor the air/fuel ratio, or you can add a wide-band air/fuel ratio gauge to the car and make adjustments on the street.
My previous car (SRT4) had a much bigger turbo along with a bigger fuel pump, bigger injectors and so on.
It had a piggyback computer added to the stock ECU. It monitored everything, like the throttle position sensor, map sensor, rpms, injector duty cycle, air/fuel ratio via the add on wide-band gauge and so on.
It also controlled the bigger injectors that replaced the stock ones, so the car would run normal, all while fooling the stock ECU.
It could record and play back "runs" for tuning, so you could look and see what your air/fuel ratio was at any given point of the rpm range, see how much boost you were pushing at that point and also see the injector duty cycle to know if you have more fuel available.
Anyway, all this can be done on just about ANY car with one of these types of computers. Its just a matter of time getting it working and tuning it all.
I loved the 24 psi of boost I was pushing in my SRT4, but it seemed I was always tweaking with it, which was one of the reasons I sold the car.
I just lost interest in messing with it all the time and wanted something simple again, and bought the SRT-6.
What I cant believe is how long this thread is about a twin turbo kit that still isnt proven to even exist, and yet he wants people to commit?
If it really is all built, just waiting for install, where are the pics?
Where are the specs?
