SIMON LC Posted August 21, 2007 Share Posted August 21, 2007 I am going to fit a boost controller to my TT and all I want to do is be able to set it to 1.2 bar and maybe move it around occasionally through certain conditions.Been lookin at ones available and they seem very confusing,for example,ratio,time,off set and overtake boost.Is it just me or are all these things confusing and pointless?

Guest Chumpalot Posted August 22, 2007 Share Posted August 22, 2007 I use a Blitz Dual controller on mine. Works great. They'll all come with instructions so I wouldn't worry too much about it mate. My Blitz one is fairly straight forward to use. Quote Link to comment Share on other sites More sharing options...
heckler Posted August 22, 2007 Share Posted August 22, 2007 I have a Blitz SCBIDIII - and I have the intructions in english! Quote Link to comment Share on other sites More sharing options...
JODY T Posted August 22, 2007 Share Posted August 22, 2007 IMO ide say the Greedy Profec B Spec 2 is about the simplist to install and use... Best idea is to get it fitted properly/set up.. Then all you need to do is select high and low boost! If a boost controller is set up incorrectly you can loose your engine! You will also need the supporting mods to cope with increasing the boost... Quote Link to comment Share on other sites More sharing options...
MarkR Posted August 22, 2007 Share Posted August 22, 2007 I'm not entirely sure I'd recommend the SBC-ID, and I have one! You cannot set it on auto, so the settings are a trial and error setup, starting with low and then moving to more aggressive settings until you find that your boost is stable etc. This is fine, providing the weather doesn't change. When it gets colder, my boost goes higher etc. Nightmare! Also, the LED screens don't take kindly to heat, so mount away from high power radio and heat shield exhaust tunnel... If you're fully decatting and fitting 1.2 restrictor ring, the Boost Controller doesn't do a whole lot TBH. Gives you more control and flexibility in the lower ranges, but for the money you spend, having it over, I'm not sure I'd have done it yet. If you don't know what you're doing under the hood, it might be worthwhile getting someone to install it for you... Quote Link to comment Share on other sites More sharing options...

As long as you dont set it up to go much over 1.2bar and have supporting mods then everything should be fine shouldnt it? How wrong can you go. Just wondering as I'm also thinking of buying the greddy profec B spec2, I'm quite confident about installing the unit but I've never set one up. I was just going to go off the instructions Quote Link to comment Share on other sites More sharing options...
T2 MSW Posted September 14, 2007 Share Posted September 14, 2007 Your post is a bit worrying Jody, could you poss elaborate abit on what you mean? I understand the supporting mods bit but then engine damage is concerning\confusing me? Quote Link to comment Share on other sites More sharing options...
Ian C Posted September 14, 2007 Share Posted September 14, 2007 Simply you could set it so that it boosts too much, and lunch your turbos by overspeeding them or your engine by running lean/too hot an intake charge/both. Melted piston is usually the result. -Ian Quote Link to comment Share on other sites More sharing options...
SIMON LC Posted September 14, 2007 Author Share Posted September 14, 2007 So would I be right in assuming a boost controller wont hold your boost at say 1.2 bar regardless of weather conditions etc?I just want to set max boost of 1.2 bar and forget about it and not have to worry about colder air etc.Boost controllers dont do this?

I dont mean to worry anyone but its not like changing your spare wheel! Quote Link to comment Share on other sites More sharing options...

A bit of boost controller 101: 1) if you set it up in the right ballpark to maintain 1.2bar then it'll do it's level best. You can expect variations of up to +/- 0.1bar on your peak hold, normally it overshoots a bit once you reach full boost and then tails off as you go up the rev range. 2) however you have to tell it three things: a) target boost (1.2bar) b) a solenoid duty cycle, or 'Set' that it should use c) a ramp rate or 'gain' which is pretty much how late it waits until it tries to control the boost. Faster build, but bigger overshoot. 3) a boost controller can't bring boost below your minimum boost level. That's the boost level you get with a wastegate open constantly at 100%. So if you've got a decatted j-spec and no restrictor ring, chances are on a cold day it'll hit 1.4bar+ even with the wastegate wide open. Setting them up isn't too bad as long as you understand the principles and start from low slow-building boost, gradually easing it up. -Ian Quote Link to comment Share on other sites More sharing options...
