Boost Controlers

[linedup33]

ahh ok thanks trent..but for a fairly stock setup stage 2 mods do u reckon its enough?

n how come u didnt reply to my pm last nite

i'm running 308rwkw through my 32r with no boost controller, hks gtss at about 18-19psi.

If you don't plan on changing the boost from high to low, then there is no need for one i guess.

or not concerned about response........, this high low thing is a real misconception and is not the reason i would purchase a boost controller... in fact mine never leaves high boost... i use my right foot to determine how fast i go..

With a correctley set up EBC you can get serious power gains throughout the initial stages due to the ebc's ability to hold back any pressure to the gates until the last possible moment. on average on a 300kw car i would hazard to guess you could get around 12-20 more kw in the mid with a decent ebc over the average manual bleeder.

if you've already got it, use it. if your gonna buy it would consider something else.

checking PM's

the powerfc kit has a distinct advantage over the other units in that it enables boost correction on the maps

so it can back out timing, add in extra injection based on boost levels and so forth (if setup correctly)

it also is displayed on the hand controller

but i dont see why the pfc boost kit wont work - a fair few people use it

I've got one of these setup on my basic single turbo R33

I'm not saying you're wrong but this is the FIRST time ever i've heard of that feature on the FC-boost-add-on unit?

Boost correction? changing timing/injection depending on boost levels????

please elaborate?

I know tha AVC-R has boost levels depending on which gear you're in but that's about the most advanced feature of heard of?

But yeah, i reckon the add-on is great.

I think the so called shit myth...is a myth.

Anyone had personal bad experiences with em?

Also, if we're going to post how much power we're makng with which EBC, may as well state the boost level too which i think is relevant..

or better yet, a dyno sheet with the nice flat boost curve.

Me, i'm on the FC add on with 246rwks.....on 18psi.

Works fine including switching between 4 different boost settings.

Nice and descrete

I'm sure they're all good anyway.

Blitz SBC IdIII ftw.

Scouts honour ill post up boost response in a month or two.

the processor used in the MSIBC is bigger than that in the average microtech

LoL at MicroShite

2 examples of blown injector drivers and tracks that decide to just fall off the PCB

hi bernie

if you are using the boost control kit with the powerFC or in fact just a map sensor connected to the powerfc then the "boost" map/correction points are enabled.

that is - if BOST is reading manifold pressure and is connected correctly - the correction ramps are activated automatically.

you can do this in two ways - one is by using the full powerfc boost kit - the other is buying the denso map sensor and connecting it up to the boost kit port (i have done this).

so on my car - i have the denso map sensor (same map sensor as the avcr or boost kit) and the wiring harness, but no solenoid. boost control on my pfc is disabled, but BOST has a reading as it can see the signal on the 3 pin boost kit port (white plug).

the following corrections are used when boost is readable by the FC

- inj vs airtemp and boost (max)

- inj vs water temp and boost (max)

- boost vs IGN S.F

Guys I appreciate this thread and the good info.

I would appreciate some feedback about the HKS EVC 5.......pros & cons and where it fits in with the others mentioned here.

I'm running a PFC with bigger turbos & fuel setup, etc.

GIZZMO MSiBC best bang for buck, good enough to take out dspeeds boost controller choice... and it is run on their 1000hp GTR, i use alot of these things for guys who want killer boost control but on a budget..... the processor used in the MSIBC is bigger than that in the average microtech

who sell them and how much are we looking at?

[Beer Baron]

that's a pretty nice curve trent, but I reckon I have one just as nice!

GTR, twins, 15psi, profec B II.

Dont know where else sell them, but good old ebay has them:

http://cgi.ebay.com.au/GIZZMO-MS-IBC-Multi...7QQcmdZViewItem

$550+$12.50delivery

and there's a cheaper one:

http://cgi.ebay.com.au/GIZZMO-Intelligent-...7QQcmdZViewItem

$399+$15delivery

No im not a seller, im actually trying to figure out which is the best coost controller myself. Is the IBC just as good as the MS-IBC just with a lower boost range? or is the a more significant difference?

[Birnie]

Hey Paulr33,

Thanks for that info, i had no idea.

Still a bit sketchy on how it works but hey, i can't know/learn everything overnight

Cheers..Birnie

Those Ebay prices are above RRP......

The MS-IBC has an additional multi scramble setiing very similar to that of the AVCR except you can repress the sramble button within the initial sramble setting and increase the sramble time where as with the avcr you must wait for the initial sramble feature to expire before you can repress.

IMO you cannot look past the gizzmo IBC for bang for buck it is extremely easy to connect and quite simple to set up, with 4 settings, holds boost well and has an excellent gain setting. these are usually on the shelf for around $400 at autobarn and have even seen them as cheap as $270

I have found in the past that using bleed taps will be subject to boost spikes and factuating pressures

Cheers guys....

Gizzmo looks good also....

Ill talk to my tuner again and see which one he knows most also. Cos i guess its beeter for him to tune my car with things he knows well? Or are they all the same just different quality?

I would not be trusting a $22 ebay bleed valve to adequately control boost on a modified R33 GTR.

All do respect Blitz, it's not a bleed valve, it doesn't bleed any air at all. It's a ball bearing valve, which works exactly the same way most expensive EBC work.

Crack up a Blitz Spec R and a Spec S...

you will that the Spec R utilises ball bearing valve and the Spec S is just a bleed valve.

hahahahaha. sorry but your way off the mark about the EBC's but BLITZ was right about your $22 ebay jobbie.... is still a bleed valve.

i have got multiple valves here as i repair blown PFC's, ecu's and boost controllers of all makes and models.....

the blitz Spec R uses two (solenoids closed/atmos) spec s solenoids mounted parrallel in the housing.... there is no spring an ball the duty rate is 100% electronic there are no mechanical (springs) determining spring seat pressure like a bleed vlave...

All decent bleed valves (turbosmart, turbotech etc) are spring/ ball bearing valves and rely on a predetermined spring pressure to increase the time the valve is seated prior to reaching target boost. These ball type valves are dumb and rely PURELY on this spring pressure. Electronic ones run real time and constantly monitor boost and only crack the actuator at the very last moment someting even the best ball and seat thype bleeder can not even come close to doing.

the reason the Spec r is the best is because the twin valves actually allow the valve to hold shut longer than comparable controllers due to having twice the capacity (now your basic setup doesnt need it but twins, big gates or conditions like drift which change the load ALOT benefit from it) once at set boost it cracks open both valves and starts pulsing duty to maintain boost, twin solenoids give DOUBLE the resolution of any other controller therefore it can make adjustments to boost at twice the speed of any other EBC.... it is pure and simple pyhsics.

that is the only reason i use BLITZ controllers (and i have access to all brands), i dont use older HKS EBC valves as they are like you posted an electronic screw type bleeder.

yeah BEER BARON the greddy profec b is a favorite too if i cant get my hands on a R or IDIII i will fit or ask the customer to supply a B

And finally the PFC boost controller (mind you im a PFC fan) is very average (fine on simple small upgrades) it has no gain adjustment and the only thing going for it is te abilty to adjust boost via the handset... they suck hardcore in decent twin gtr applications.

[andz]

i had a pfc ebc'

no problem at all

just cbf going into the hand commander to change the boost, bit of a hassle

[The Mafia]

I'm interested in using the powerfc to handle the boost.

Did it work ok? CAn you go into more detail?

I'd just prefer less crap in the car. (Head unit for 3rd party boost controllers) - the Powerfc uses the Handcontroller which I think is more convenient.
