Which boost controller?

I asked the very same question, off list several months back and it was  suggested that  the Blitz DSBC was for most of us, probably the  best controller to go for.

 

I have so many old supra realted e-mails, I could not find the one concerned, I will try to find it because the originator outlined the pros and cons of each of the two you mentioned and the Blitz.

The DSBC is very effective but the SBC-ID is the best controller on the Market IMO.

 

The Apex'i can be a bit complicated and fiddly. The EVC is ok but certainly isn't as popular as the DSBC.

 

I believe that only the DSBC and SBC-iD feature dual solanoids making it a far more effective boost controller...this is also the one that Leon can set up to actually limit your boost a bit.

If its the Apexi AVC-R, I heard from a couple of people (inc. Chris Wilson when I was up there getting my decat pipes) that this unit is perhaps not best suited to the MKIV, can't remember the reasons, but I'm sure if he reads this, he might elaborate.

 

Personally I loved the DSBC for its simplicity, you didn't have to fiddle with 1000+1 variables to get the boost you wanted, if you do stuff up the settings on the AVC-R, I wouldn't like to recover them...

 

Also, if you don't like the black DSBC with green LCD, do what I did and get the chrome one with a blue backlit LCD - looks v.cool IMO. Quite neat as well because you can put it in the bottom half of the double din stereo unit (assuming you have a single din head unit), with the mounting plate it comes with, also you can chuck a couple of gauges in the same mounting plate. The AVC-R is difficult to locate in the Supe, I offered it up to quite a few places in the interior when I was down at TDI, and wasn't happy with any of them, looked very tacked on. Unless of course you do what Justin did and mount it in the roof.

I agree with Alex/Eric, I haven't yet got one but having done a bit of research think the Blitz SBC-ID is probably the best in terms of information & ease of set-up. I like the chrome/blue one too!

I'm all for individuality but not at the cost of forgoing the best for the job! Maybe the others are rare for a reason.. But then I expect those who run Apexi etc would disagree. :smile:

Hmmm maybe you need to ask why that is ?

The other thing you might want too consider is reliability. I have been knocking around the Supra boards for about three years and I cannot recall failure of a Blitz but at least two Apexi units. HKS by virtue of their rarity ....who knows what they are like.

That was something i was going to mention, but didn't have a lot of data for comparison.

 

I have heard of one DSBC solenoid failure and supposedly Blitz just swapped it straight out for the customer.

 

To me that's quite an impressive record on such a popular piece of kit.

I *think* i am just going to take the plunge ;) and go for the HKS EVC PRO. But i'll confirm this nearer the time.

 

 

Good luck,lets hope the manual isn't in Japanese :biggrin:

hi intresting reading,i fancy the new blitz boostcontroller with the power meter id.they seem to have loads of features.

 

are they easy to fit or would you better getting someone like leon to fit.how much would it cost to get one fitted any ideas?

 

also do they have a boost gauge built in or do you need a boost guage,i was wanting an electronic boost gauge 60mm HKS

also an EGT gauge too.what other do you need oil temp?

i wanted the 3 pod pillar mount or passenger airbag mount,has anyone got any pics of installs to see how they look.

 

the new blitz does sound good,do you tap in the amount of boost you need.

 

any price on any of above parts

 

thanks in advance

Syed,

 

The HKS EVC Pro is an incredible unit (see http://www.hksusa.com/products/more.asp?id=673) but it uses fuzzy logic. This is fine for a single turbo or twin turbo's in parallel (TTC) but not recommended for sequential turbo's. For the latter the HKS EVC EZ is recommended, which also works well on single turbo's. The APEX'i unit is also not recommended for single turbo (i.e high boost) installations. Most US single turbo specialists use the HKS EVC EZ. It is very simple to use and controls boost well.

 

I have the Blitz SBC-iD with the Power Meter (I'm a gadget freak!) and it makes a nice combo. I have been told that it's also available in Japan with a green display which would match better with the other dashboard lights.

 

Final tip, make sure you don't use the power steering vacuum line for the boost controller display vacuum input, it will give strange results. It's better to T into the standard boost pressure sensor.

Ohh errr...which one's that then????!!!!!!  I'm sure mine is acurate...never noticed another one I could plumb into.

 

The SBC-iD has one pack of wires which end at the actuator in a plug...at the other end all you need to do is splice the power in, and plug the other plugs into the control unit. attach the vacuum hose and you're off (having already fitted the actuator and hoses.

 

Very simplified version of events only difficulty is getting the wires and hose from the engine bay and  into the cabin (coathanger for feeding required)

 

Have a look at a car with th DSBC if you havn't got a local SBC-iD the wiring is very similar and the actuator is the same, just the control units are different.

 

I'm in Norfolk which is a bit of a trek to just look at how the SBC and Powermeter are installed!!!!

Alex,

 

On the pic below you see a green sticker. Left of the green sticker you can just see the T I used for the vacuum line that goes to the boost controller display.
