HKS FCD (Fuel Cut Defencer) Опции

Интересует,1 почему не рекомендуется устанавливать на сток турбины Hks FCD Fuel Cut Defencer и 2 принцип его работы

[Sub]

The reason that the MkIV owners recommend the GReddy BCC over the HKS Fuel Cut Defensor (FCD)and the Free Fuel Cut Defensor (FFCD) is simple. The HKS unit reduces the signal coming from the turbo pressure sensor at a fixed percentage, which means that all the data coming from this sensor is corrupt.

The HKS FCD and the FFCD either modify or eliminate this feedback to the ECU and put the EBV in fail-safe mode which fully opens the EBV at only 2500 rpm. This causes a severe drop in boost at the transition between single and twin turbo operation, some owners have seen boost drops to as low as 5 psi before the #2 turbo comes on line, then sudden spikes as high as 17 and 18 psi that will really make you think that you have more power when in fact you are killing your midrange power and then suddenly bringing back full power. While not damaging to the turbos because you are providing plenty of prespool to the #2 turbo, it really masks the true potential of the car, and makes the car harder to drive smoothly.

...using the hks fcd or the ffcd is only recommended if you have the ttc mod and 12v mod
