| Post subject: | st205 blitz spec s set up |
Hi im new to the forum and have recently purchased a blitz spec s boost controller. for some reason its over boosting. does anyone have any idea as to why this is? pics would be very helpful thanks. it seems to do it when i gear down and push on the accelerator or when im cruising in any gear and put my foot down. i have the gain set down on 3 and 5 percent boost. Many thanks |

A bit more information would be helpful. When you say you are overboosting what boost figures are you seeing? I used to run a Blitz DSBC Spec R and found the instructions on this link very helpful http://www.rtec.ch/dsbc_manual.html I can't recall exactly what gain and volume I ran but the 3 and 5 you mention do seem pretty low. If you have replaced the cat with a free flowing downpipe then this will make a big difference and it will make it easier to overboost, particularly if you give the throttle lots of welly! |

Hi, you just have gain to adjust on the BC? or is there also a set? 3-5 is very low which means nearly no boost controll, makes me think of a air leak anywhere to the acutator of the turbo or possible wrong lines on the boost selenoid (there is a in and out port!) do you closed the line to the oem boost selenoid aka VSV? greetz |

for reference the gain i ave set ( for overall boost response or whatever on the blitz manual it recommends 5.. for the gain for each individual setting i ran 56 on setting 3 and 60 on setting 4 and these acheive around 1.1 - 1.2 bar |

www.gtfours.co.uk > downloads There is a guide on how to setup the Blitz DSBC there... I too have seen/set a very low gain on to achieve a decent boost level and system response... |
