Electronic Boost Controllers

[51jay]

Jimbo2000 What's your opinion of the E-Boost?? does it spike at all?? I've just finnished wiring mine up but will be a few days befor it gets driven.

EMS have boost control...but not sure if they can use the factory solanoid

[rs73]

Even people with top of the range Motec ECU's still have a seperate boost controller, some even the SAFC aswell. Alot of supras do this in america, especially in their supra movies. I guess they have lotsa money too

Reason why most aftermarket ECU has separate boost controller is the extra tunability. Even Apexi PowerFC's boost control option (extra few hundreds of $$$) is good, however still not as good as its sister product, a stand alone AVC-R. Not in terms of quality or operational but in flexibility and tunability.

nah its good like that, no spikes, just watch the digital readout climb all the way and sit there.

i'm more than happy with it, just get someone who knows what they're doing to tune it, took it to a somewhat respected workshop in syd and they'd either never tuned one before or they were just really crap. actually had to come back later to give them the manual.

i can do avcr tuning - guaranteed to come on stonger, earlier =)

the only issue i have with the avcr is it doesnt fit into a factory DIN. so i leave it in the glovebox.

Hmm... problem is not many standalone ecu for that price incorporates everything. Not sure about Wolf but even PowerFC DOES NOT have a boost controller embedded, it is still an option add-on that you need to buy.... so as far as I know there hasn't been any so far... unless u can show us which aftermarket ECU has boost controller included for that price.

wolf3d has built in boost controll which can be accessed through a laptop (dont quote me i could be making stuff up here )

I have mine mounted where the ashtray use to be. Once you know what the broad brush strokes are for setting up its actually pretty easy. I can get mine to hold stable boost without spiking at 1.1bar when the std wastegate pressure is 0.65, so can easily to the job. I think if i want to run any higher though she will start to perhaps struggle and ill have to wind in the wastegtae to about 0.85bar to endure it is stable at 1.3bar.

Get whatever you like the looks off, and just ensure it is setup correctly as they all work well when installed properly.

...oh what mad bugger would buy a Motec only to use an SAFC. A boost controller i perhaps understand as that frees up an output on the ECU to be used for other things, but an SAFC on an M48 let alone M8???? I wish i was the workshop selling this guy stuff

[Evil]

yeah avcr is a great ebc had no problems with mine...

Selling me stuff? are u talking to me?

I see it all the time, probably 4-5 cars now.

I know they do something with it, not sure why, but they do.

No wasnt referring to you specificly, but the cars you have seen.

Just saying if i was a workshop id love to have clients who let me sell them a fuel/ignition ECU like Motec M8 (you did say top of the range) then only to sell them an SAFC as well.

Doesnt make sense, like i said the boost controller frees up an output to be used for something else, but it doesnt make sense to use an SAFC on an ECU that offers superior control over fuel and ignition.

[knore]

I know, i never said they were smart

Ide assume they had the SAFC already when the got the other ECU etc

It would allow you to change fuel settings instantly, where in full EMS you can only change maps that have set setting.

Or something like that

i had a TurboXS bleed valve on my S13, it had full exhaust and hybrid cooler, stock turbo SR, the bleed valve worked quite well for 1bar, then i got a 2nd hand Trust/Greddy Profec B (spec 1) for it and it boosted better and for a bit longer, when playing with the boost response knob (forget its exact name) but really didnt make too much difference really just coz of the stock T25G being out of its effeciency pretty easily and always wanting to bleed boost.

in my DR30 it has an older style HKS EVC and i find this to work really well on this car. running about 1.1bar and it goes up and stays there really well, never ever spikes or jumps around. i have catback exhaust (soon to be full =]) and a small FMIC, stock T3 turbo (FJ20)

Heres some info for all you.

The profec b spec 2 is useless with an external gate.

is that why u asked me abt hks evc today?

well, in hks evc there's a switch at the back of the control unit to select either internal/external wastegate. didn't the profec b spec2 has somehting similar?

maybe hidden in somewhere in the webs of its electronic menu or options, unlike a swithc or something.

[GZ R33]

I prefer the AVCR, if later on you get a PowerFC they work perfectly together, my mate has the HKS one and when he comes hard on boost the thing registers all 8's because it can't keep up.

[dAVE]

profec a spec (the older model) had an option for external gate.

best boost controller is the latest HKS... works very well and looks neat.

[T0nyGTSt]

Any of you guys wanna tune my AVC-R?

ROy, Frank??? I'm just eff'ing around with mine up 'til now

AVC-R only has two settings though. Looks a bit 'primitive' against 5 or more from the others.

Profec b has a seperate intake into to the solenoid for an external gate but the solenoid aint so great with the ext gate.

HKS EVC 3 or 4 with the stepper motor works the best with ext gate.

hi there.... can i get some help from you guys?? i have just installed a Blitz Dual SBC Spec S into my R33 gtst and was wondering what is the settings you guys have in it?? i want to increase my boost up to 0.8 bar.... any help would be apreciated... thanks.. :headspin:

cheers

[adznight]

Yeah I have an AVC-r too, Lot of people bash them though saying they dont hold boost etc but then I've head a lot of good things too!
