As some of you are aware, i have been using a boost controller on my car for some time now. Well, what is a "Boost Controller"? In it's simplest terms, a boost controller can be a simple spring loaded device using a ball bearing as the"pressure relief" valve, this type of controller can be surprisingly accurate. The type of controller i am talking about is an electronic device with, as can be imagined, many and varied parameters that can be user set. As a for instance, maximum boost, warning buzzer, shift light, override, and many other parameters. In our cars, the S2, there is already a boost controller fitted in the shape of the WGFV or Wastegate Frequency Valve. It is however, not user adjustable.
The type of controller i am talking about here is user adjustable and has many different functions. I have mine set, at the moment, to give boost to 1.35 bar. This is purely personal preference and at one point i had it giving 1.75 bar, that was a moment of insanity that i will not be repeating. Please bear in mind also that i do not have the stock wastgate spring but something different. The real beuty of a boost controller is that it CANNOT produce more boost than the wastegate spring is set at - ie. if you leave everything as standard and only install the boost controller, you cannot produce more boost than the standard setup. Start altering spring tensions and it will produce accordingly more or less boost. Bit like my 1.75 bar!! But as i have said, leave everything standard and any numpty can install one and not ****** their engine up (there ARE exceptions, as in every rule:-)).
The boost controller replaces the boost control chip in your ECU, no, you don't actually put it in your ECU but you do not connect the boost pipe to youir ECU either, the boost controller now takes over that function.
I had thought about replacing the MAP sensor in my ECU with another, indeed, i HAD fitted a 3.5 bar MAP sensor to my ECU, this would undoubtedly give me better definition but in the end the added features and functionality of the Boost Controller was the way to go i decided. The right desision too at the end of the day.
The features i like best. Well, my wife drives a 2.6 litre v6 thingy and really likes the extra a turbo gives. I can, with the aid of the Boost Controller, limit the amount of boost available, at the flick of a switch - or as in the case of the Greddy controller i am using, the press of a button. The device has three primary settings in essence, High (me 1.35bar) Low (her 0.8bar:-)) and OFF (that would be anywhere else, like servicing etc. where there is only 0.5bar available:-))). This severely limits the antics of any would be race or rally drivers who have your car for the day.
Fitting is a really simple affair with comprehensive instructions supplied. I had looked at several and decided on the Greddy. The decision was based on several factors and in hindsight i wish i had bought the A'pexi controller but this does not mean that the Greddy is no good, it is excellent, i would have been able to use a few of the extra functions in the A'pexi though. I know Mark is able to supply the APEXi AVC-R unit at a very competitive price. This unit is able to control gear specific boost for example, you can say how much boost you want in each gear.
Just my thoughts.

), looked like a nice bit of kit.
I was refering to fuel maps within the ecu. APFR and the crap FSE valves i've seen used many a time to overcome leaning out which dump shed loads of fuel in, bit like a digitech chip eh Ski.
