You forgot the other downside of these electronic controllers - quite a lot of them do not "failsafe", i.e. if the power supply to them fails for any reason (or someone switches the power off by mistake), instead of reverting to the lowest boost setting, you get UNLIMITED boost

Neither do air injectors.... in fact, the poxy old AMAL valve is best in that respect...

That one looks good, but whats this "boost numbers" about. Surely you want to put 20psi in and hold 20psi not enter a random number to achieve said pressure?

Yes, but at least air injectors / amal valve can't be turned off by some monkey / child playing with buttons in the car 
. Also the air injectors are powered by the ECU, so I don't think the car is going anywhere if the power supply fails to that . Although I concur if you just unplug them, as I have had that happen (luckily I know my car intimately (oh er ) and realised instantly that boost control had been lost

As stu says, you can't beat the amal valve for fail safe conditions (unless it blows apart and then we have unlimted boost too, PMSL )
Actually lets all go back to bleed valves. At least this way you know what you've got! lol

It's sound a bit strange but it's really quite easy.
Takes ten minutes and an empty dual carriageway to set up

Also, as it clearly says it cannot perform miracles and can only operate within the limits of your turbo, so don't expect it to be able to bring a T4 on boost from 1000 rpm or for a T3 to hold 30psi at 7k .

As Steve C said the Greddy boost controller IS fail safe.
Switching the unit off (by using the front panel switch) or power failure to the unit reverts to your actuator set boost. On mine the actuator is set for 14 - 16 PSI so thats ideal for warming the car up for first few miles, then you switch the unit on using the front panel switch and you now have active boost control.
Mike, the most amazing thing IS the low down performance of the Greddy......IMO prob only helping "a bit" as a T4 comes on boost..........but as you know every little bit helps, especially when i'ts for FREE.....and relative to the price of air to air is is FREE

Testing the future
c'mon SECS. i've already said that your S8 will do it for 2 - 3 times the price of a stand alone boost controller.
but we need it to be widely available, and with a supplied map more or less for 'traditional stg 3'. then, no question, i would buy an S8 tomorrow.

I had an avcr on the datsun and ran it at a bar every weekend when out playing then .7 bar during the week to commute. Never let me down once.

i've been using a boost controllers for about 3ish years tried a 2 i found the blitz works the best for me so far
i swapped to the apexi = shit, random boost spikes hard to get a held figure abs sensor's don't work for the speed sensors. so i changed back to a blitz controller.
the only problem i had was trying to get it live mapped when i first fitted it.
cheers

Mike : The GReddy Profec B 2 has all fail safe features that an air injector would...............
Check it out on one of the web sites.
If people are genuinely interested I'll see if I can get enough units to make it worth while for us. But even at $320 (Thats still under Two Hundred Quid, and all I'll add it the postage back to Uk, and I'll label them as used car spares. After that I can't garentee the Customs Guy wont open any and check them. I've done this with Mike Rainbird before and we've been lucky, but I cant give a garentees.
The units come with a world wide garentee, but if you had a problem I'm not sure where you would have to return the unit too. Please check the unit out on one of the web sites and make sure it's what you really want first.
Don't want anyone saying they thought it was something different.
I'll give it a few days and see who would be interested.

PMSL at you lot. Is your ideal Boost Controller one that has a failsafe?? Regardless of how well it performs?
My Blitz controller has no failsafe, but having said that it does what I bought it for far better than any other I have seen, control the Boost. If I was that concerned about the unit failing and running unregulated boost, I would buy a warning device, such as an SPA/Defi Boost Gauge, which will have a peak warning, but I think I know the car fairly well and would notice fairly quickly if it suddenly produced 3-Bar of boost. Famous last words eh?
Perhaps you also need a warning device to tell you when the wires are going to break off your fuel pump or that your conrod bolts are under slightly more tension than they should be. The point is that you can worry about every 'maybe' circumstance and it will be the one that you forgot that will let you down.
The Profec-B is one of the better controllers. However, don't take the fact that a controller works well on a Jap car as being an assumption that it will work on a Ford. Been there, done that........

How easy to install?
