which one and why?

fc3sboy1 08-12-2005 05:01 PM

manual ball n spring, why real quick spool and is always steady if using a proper controler like xs or something and can be fine tune quit well and is flipping light as hell. and alot cheaper!

rfreeman27 08-12-2005 11:11 PM

love my apexi. I dont really use any of the features, it is just a rock solid system.

profec B version 1, if you see how big the solenoid is you won't ask why....

Maxt 08-14-2005 08:17 PM

I have run a profec a, haltech boost control, turbosmart mbc, and now a blitz spec R..

I have been in a few cars light tuning with a profec b..



The profec a is pretty wonky bc, the haltech was either 7 psi or 20, no in between, the manual boost controller from turbosmart changed setpoint everytime I ran the car, never held consistant boost.

With the profec b, we have found that the wasteagate tends to hang open with vacuum through the shift killing spool up..

I bought a blitz and its great unit, the spec r doesnt have alot of gadgets its pretty plain, but the boost is rock solid and hits consitently every time...

I have been told by some pretty reliable sources that the profec b has a problem with spool speed on large turbo cars and tends to overshoot the boost setpoint ..Maxt

Weren't people having issues with the Profec II? I thought it was all about the Profec S? I maybe wrong. Been thinking of getting the Profec S though.

I'm with Braco66 the Innovative MSBC-1 one of the best boost controllers out there and that's why I've have one. http://www.innovativeturbo.com/cgi-bin/htm...885159911870415

blitz sbcid because you have my old turbo kit and i know it works on it PERFECTLY. the only slightly annoying thing is letting it learn the boost curve but it doesn't take long https://www.nopistons.com/forums/pub...IR#>/smile.png

treceb 08-15-2005 01:51 PM

yes, but can it do this..."It can be used to provide LOW, MID, and HIGH boost stages for your street vehicle or creating a separate stage for each gear in a drag race application"?





the only reason i liek teh turbosmart is cause i can just drop it in the gauge pod and then theres no need to have a boost gauge and controller separate...

Yep...both are a couple of the reasons I went with the EBoost 2.



Overall, It is cheaper to get the Eboost system, than to buy another Controller and boost gauge seperately.

treceb 08-15-2005 10:16 PM

i like how when i bought the car all u saw was the turbo timer sitting on the steering column and the boost gauge on the pillar. boost controller was hidden.

the turbo timer is coming off and id hate to have something sitting somewhere visible attracting more attention.

let me know how that boost controller works for ya. any and all feedback is greatly appreciated.

vosko 08-15-2005 11:13 PM

the blitz you only need to have the commander in view and it has 4 presets for boost than you change in two clicks. the blitz has peak hold and real time boost.

kahren 08-29-2005 01:35 PM

i vote for a profec b2



the apexi avcr is great controller except its alittle hard to program and takes some time. good for turbos that dont like to have a linear spool and boost responce. lots of adjustablity



blitz SBC id this has got to be one of the easiest contorllers to use, set the boost let it learn (beat on the car a few times) and it will hold your boost settign solid.



eboost2 i have never used it and have no idea what it is



the profec b2 is a great cheap boost controller, might be alittle confusing for some to setup as the directions that it comes with are a direct translation form the japanese language and they dont make much sence. this boost controller has some problems controlling small turbos with non restrictive exhausts that like to spike and boost to whatever level they want to (would be hard to setup a consitent boost level maybe even impossible). with bigger turbos this boost controller is perfect, solid boost levels, low and high boost setting switched easily with one button. cheap alternative to the avcr and the sbcid.



if money is no object i would go with avcr or the sbcid.

treceb 08-29-2005 02:22 PM

if money was no object id go for the innovative....lol

I have personally owned or installed and used all of these mentioned. I like the E-Boost and the E-Boost2 the best because it is so simple. Just a simple gauge and solenoid, instructions are simple, and there are outputs on the E-Boost2! I mean, it can be a tach, boost gauge, shift light if you buy the ring that goes around it, nitrous control, methanol control or water mister control! It has 6 mapping functions, overboost dump protection, holds boost at higher rpm, etc.

Cheers! 09-02-2005 01:41 PM

I vote for the apexi avcr. Rock solid, never had a problem with it. The features like gear judge allow you to manipulate teh duty cycle based on RPM for that specific gear. So if you know you are constantly burning the wheels coming out of a coner on the track you can ramp the boost such that it comes on a bit softer for the second you need to get the car pointed straight again.

Maxt 09-03-2005 09:56 AM

I just got a blitz dual solenoid... Best control I have tried yet, the most stable boost I have ever datalogged, no waves, no drops, no spikes, and by far the sharpest boost curve I have ever experienced...

I have used the turbosmart mbc stuff, profec's and haltech boost control, for the purchase of the blitz I did some research, asked a couple of big name guys I know in Japan and everything pointed to the blitz...

The profec b is a good choice for stock turbos with quick response, but it does have a problem with large turbos with lag, the gain has to be overset somewhat to get a boost curve comparable to other controllers, which then leads to overboosting, then if you set the boost lower to put up with the spike from the gain setting, on slow boost up it results in lower than desired boost...

With the blitz, the gain, has little effect on the peak boost, but does affect the sharpeness considerably, I started off with the gain high as all boost junkies do with big turbos to get the hit, but ended up softening the curve to limit traction loss through the midrange..

The haltech boost control was ok, but for some reason the ecu decided when boost was going to happen, it was either 7 psi or 20 psi, with no rhyme or reason to its picking of which one... Tapping the gas just prior to boosting would seem to pick 20 psi.. Must be a bug in the firmware on the e6k..

The turbosmart mbc stuff was crap, to inconsistent from day to day..

The other EBC I ran was a profec A, fuzzy logic indeed, so fuzzy even greddy couldnt understand it, very wavy boost and not worth the time of day..Maxt

Is this the Blitz SBC Type R that you are talking about? Have been looking at one of these or the Profec S.



Anyone have any thoughts on these two?

KingFD 10-20-2005 06:55 PM

Well thanks for the replies guys https://www.nopistons.com/forums/pub...>/rolleyes.gif https://www.nopistons.com/forums/pub...#>/biggrin.png



I've just bought the Blitz SBC-ID III. Will be putting it in this weekend.

KingFD 10-23-2005 04:28 AM

Just thought I'd give an update on the SBC-ID III.



Put it in today without too much trouble at all, did have help from a friend who has done one before. Was pretty easy to set up i think we looked at the instructions once just to find out if we needed a constant 12v turns out it's just ignition 12v.



Had it in auto mode with our peak boost setting selected and seemed to come up quite slow and very controlled. After a few hard runs it got alot quicker. Very impressive. https://www.nopistons.com/forums/pub...IR#>/smile.png

sweet7 10-23-2005 04:34 AM

Glad you like it, im planning on getting the same one.

l8t apex 10-23-2005 03:34 PM

HKS EVC IV or V , learnmode and the external steering wheel boost button!

Launch at low boost wide open then hit the button for max boostin top gears.

Have to totally agree with Max. I was fighting this exact issue all summer. Even with a 46mm Tial WG, I had to open the WG (SET GAIN) much sooner than expected to prevent spiking. This, of course, hurt my spool up.



I decided to live with a spike instead of slower spool. Shitty comprimise that I'm not happy with.

Midnightdriver 11-28-2005 05:01 AM

Greddy profec B ver. 1....simple to use.

works2r 12-25-2005 11:15 AM

out of all of those, i'd suggest either the AVC-R or the SBC id..

better solenoids, less failure from what i've seen.



i've been running the HKS EVC Pro (basically EVC IV w/ATM and ATS) for like 4 years rock solid.. (i'd suggest the evc, but you aint lookin at it.. although if you are looking at innovative, why not just get the NLR AMS1000, its a better unit..)



if you really have all sorts of money to spend, then i'd suggest a Pi Sigma System monitoring and telemetry hooked up to a MoTeC or Magneti Marelli https://www.nopistons.com/forums/pub...IR#>/smile.png
