I can recommend the Profec B, on the dyno with the boost displayed digitally in remained within 0.1 of a psi to the set limit. The low setting is good for situations where a bit of wastegate creep is needed eg. in the wet or heavy traffic, you won't get full boost at light throttle, but in high there is no wastegate creep at all as I can have 12psi at less than 30% throttle.

ProfecB gets good wraps compared to the more expensive units around. One of the mags did a comparison somewhere, i am sure you can find reference to it on the net.

No rice factor but it does what it needs to well.. the "sharpness" knob is a useful one in my car.. basically how it was explained to me is that it it controls how tightly it holds or releases the wastegate. To me if i turn it to "sharp" it seems to spool up a little faster and "crisper" if that is a correct way to describe it... so i play with it on the road and adjust 25% either way depending on what i want.

Seems to do that, however can also be used to reduce spiking or boost dips on the dyno

Myself and 3 other guys in perth have the blitz sbc type s, its got 5 boost settings as opposed to only 2 on the profec, it reads boost in bar so it acts like a boost gauge, unlike the profec. Quite simple to fit and setup, holds my boost at 12.5psi very well except when the valve timing kicks in and it drops to 9psi, but thats something to do with my ecu.

Pred, the BALANCE knob is actually to adjust the boost from rising or falling as rpm rises, so starting from the middle point if boost rises with rpm turn the knob towards the SHARP side and if boost falls with rpm then turn towards the MILD side.

spec s is the single solemoid aint it?

i talking about the spec r dual solenoid

i'm using a blitz dualsbc for a few years now, at fiirst no one really knew how to set these now after trial and errors and tunning and details from net. once it is set up properly it is a devastatingly accurate and powerful controller. nothing else i've used comes close. it has digital boost reading so u can get rid of the 50mm guages and , it has a max boost memory and a few other nice function.

I'm having a problem with mine. It's just started ticking. I took it to the mechanic he said it was just the solenoid ticking but that its not set optimally and apparently alot of power is being lost and more fuel is being pumped to compensate, due to it not being setup well.

What kind of settings should I run on the blitz ebc? I think I have it set at 50 gain and .8 bar it gives 12psi on a analogue meter.

Also since this was in my spool time is alot longer a bloody excel can beat me over 30m heh.

Even if you have a different setup what kind of settings do other people use for optimum performance?

What kind of settings are you using SeriesIIGTST? I'm lost on how to use it. heh I just dont have much of an idea. When you start getting into Gain and Ratio I get confused.

What type of boost are you running on your S2? I run 12psi dunno how I set it but thats what a seperate boost gauge reads.

well mate if u noticed i have started a few thread over the last few weeks about turbo choice and wtb - parts and now boost controllers!

I have been collecting the parts and getting it all installed at once!

When i finish all the installation and tuning then i will start a thread, just for u :P

      Ticking Sound On Idle - Rb25

      By GTSBoy · Posted

      Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!

      Ticking Sound On Idle - Rb25

      By myrbgivesmeheadaches · Posted

      Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers

      Ticking Sound On Idle - Rb25

      This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?

      Sorry for reviving an old post, but I'm having the same hot idle tick issue. Did anyone ever find out what it was?  I have checked/ replaced Injectors Coils checked Lifter clerance (is at zero) Checked Cam lobes Replaced exhaust gasket and studs Would appreciate any advice this is driving me nuts

      There's a huge reason manufacturers are tuning in dead flat torque curves... Make them reliable (and more drive able)
