boost controller
 

So my HKS evc6 took a ****. Think it's the boost solenoid but figured out it was the boost controller not opening up all the way to 12lbs.

So to all the boosted guys out there what boost controller are u guys using? Thinking of going with the aem tru boost

If you're not going to be changing boost levels, do you need an electronic one? It could have been messy if it failed the other way and you had uncontrollable boost.

I got a manual boost controller. I'll prolly stick woth that. Not as cool looking but it gets the job done.

I'm fine with my manual TurboXS. Cheap and does the job. I don't change the boost level ever, and an electronic one would tempt me to mess with it.

well my Z isnt turbo yet, but I do have the New Greddy Profec OLED ready.

On my supra I am running the older unit, Greddy Profec B Spec 2. It holds boost stable and is super easy to adjust. Original tuning on it does take some time with several pulls until you get it set where you want it, but once set you can forget about it and let it do its work.

I assume the New Greddy Profec OLED i have for the z will work just as well( I know they shrank the actuactor size down) Only difference being a viewable screen to view the boost graph and other features.

Greddy worked very well for me in the past so I had no reason to switch to hks or blitz styles.

Ive got the same Profec OLED mounted in the ash tray of my Skyline waiting to be hooked up. Greddy have a good reputation but I obviously cant vouch for how good it is yet.

If you're interested elpureno, the best price I could find anywhere was actually an Aussie site that gets them directly from Japan. Check out Nengun.com if you want to go that way. They always seem to have awesome specials going for heaps of gear.

Thank u sir.

You guys running manual boost controllers dont have issues with spike? Maybe this only occurs when running higher boost levels.. but I know it was a common problem with my STI and Evo buddies. Im running the turbosmart E-boost 2 and am happy with it so far.

I'm not, but I'm not running internal wastegates and I'm only running 9-9.5 psi.

With a proper wastegate configuration (external wastegates) you will be just fine with the manual BC. When we tuned the prototype BP turbo kit (dual tial v-band wastegates) it worked just fine. No boost spikes. The boost did taper off at the top but that is largely due to the VVEL. The power did continue to climb to 550whp.

My set up is internal wg. 12 lbs. I hope it don't spike up but so far so good.
My buddy pretty much made it him self. Looking into a more long term solution. The greddy or aem r my choices for now. TurboXS seems a good choice as well.

TXS also has a manual that has two settings for a low boost and a high boost setting. It's still pretty cheap and they make good stuff.

I just switched out my HKS EVC-S to the Go fast Bit G-force 2 boost controller so far I like it way better than my HKS unit.

This thing has 6 boost settings way more than I need.

i got my aem true boost working and its great
boost comes on harder then with my manuel boost controller

That thing looks sweet. One of these may be in my future. My EVC-S works great, but is such a pain to edit boost curves with. Nice to see a company putting out a decent product without the brand name markup.

I like the boost controller so much more than my EVC S that it replaced and would highly recommend it .

What is everybody's opinion on the HKS EVC-S controller? As my sig says I was set on that for my TT setup, that is being installed as a DIY this winter. It would match my HKS turbo timer so I figured it would be nice to have a theme going. Out of the little reviews I could find, they all seemed good.

Anybody have any personal experience with it?

They r good just kinda complicated.

So what are the pro's and cons of either? Really curious :tup:

the evc-s does work well, it's just confusing to setup if you don't understand the variables being changed, and most don't because the manual is confusing as hell. After owning one for awhile I eventually figured out how to dial them in well, it's actually very simple to use.

The go fast bits is a great controller that has very good closes loop correction and supports 6 boost maps and sensor calibration. Only thing I don't like about it is you have to run a vacuum source into the cabin (no remote sensor)

That is the only reason I haven't purchased it. I'm going to check out the new one from Innovate Motorsports.

Hmm.. educate me. I'm under the assumption an EBC would keep the wastegates closed longer for better response. How about feedback for more accurate or consistent boost regardless of ambient temps and air pressure?

EBC can keep the wastegate shut for better response if you ask it to (typically called GAIN), you need to adjust this carefully to avoid an overshoot/spike depending on turbo size and boost levels.

As for ambient temp adjustment, some factory ECU's with boost control do this, but I don't know of a single aftermarket boost controller that factors in ambient temp when doing closed loop correction.

I loved my PROFECT B, When I was running it on my EVO, I ran a Turbo XS manual on my other one and all 3 of my Eclipses. I only had boost spikes when the temp were cold" normal tho"

Apex'I AVC-R ftw

Boost by gear, no spikes.

I want boost by gear. Supposedly with the evc6 boost by gear doesn't work properly.
