More on air/fuel and the BCS
Okay, I hear some skepticism about the air/fuel issue. Here's what I know:
- From personal experience dyno testing with a wide-band air/fuel analyzer, I know the stock programming runs extremely rich on boost.
- Split Second spent a year developing the boost controller. It is limited to 1.0 bar because they found that to be a conservative safe limit on stock fuel trim.
- There are about 130 of the devices out there, installed, and on the road. Reports of "blowing up" from lean mixture: ZERO.
Draw your own conclusions.

It may run extremely rich, but THAT rich for claimed 35hp??
>>- Split Second spent a year developing the boost controller. It is limited to 1.0 bar because they found that to be a conservative safe limit on stock fuel trim.
Most of the bigger tuners spend yearS developing chips. 1.0 bar is also the highest that any of the tuners run with the CORRECT fuel trim...
>>- There are about 130 of the devices out there, installed, and on the road. Reports of "blowing up" from lean mixture: ZERO.
130?? THATS IT!! Sounds like you are just playing roulette. Chip tuners have THOUSANDS of chips out there without blown turbos...
