what do you prefer

I would say go with a manual, less problems. Better yet, get one of 2 stage manual ones, I think Turbo-XS makes it.

i'm liking the more natural response of the wastegate, but i will be using a bleeder valve once i get the ic in

after seeing what my boost pressure did on the dyno..... no way i'll use a bleeder valve or spring pressure again.

AVC-R all the way

Ditto

I've got to go with the manual boost controller. I haven't really needed mine yet breaking in my engine but it is so hard to screw up. I had the AVC-R before and I could never get it to work right. I think it was me because Steve Kan just looked at it and it straightened up.



My boost controller is the dual stage so I can have 2 settings with was a must for me. If I couldn't have gotten that feature then I would have still picked another boost controller than the AVC-R. Probably the profec B...

I concur as well. The only bad thing about the AVCR is doens't allow you to use a simple push button to select between the HI and LO boost or off. You have to hit prev to get out of the data log/display mode, then hit prev again, then scroll down then hit left or right to change between. Not just a simple push.



damn



oh well...

I dont understand why someone would want to have a complicated boost controller. I have the profec-b but im going to ditch it someday and get a 2stage manual.

The simplicity of the Profec B is 2nd to none. Manual boost controllers are junk compared to EBC's. They might be able to make some people happy, but I'd never go back to using one. Reasons why? This subject has been covered about 1,000,000 times already.



Going from a MBC to a EBC is sort of like moving on from eating only Big Mac's to eating Filet Mignon. Both will fill your belly and taste good, but everybody already knows which one is better even though pricier.



Wastegated? Perhaps the best way from what many have experienced, but I've never gone with such a setup.

I'll be goin scraight WG spring with my project for a little while...so I can get used to driving a RWD turbo car.

EBC...

MBC's can't touch it for ease of adjustability...more aggressive boost ramp...and consistancy no matter what the ambient climate is.

I love my 1G Super AVC-R. https://www.nopistons.com/forums/pub...#>/biggrin.png

I can switch from setting A to setting B with one touch of a button...unlike the newer 2G version. https://www.nopistons.com/forums/pub...IR#>/smile.png

I used to same the same thing until my Profec B took a **** and would not keep my boost consistent.



I was gonna throw in a Motec one but was out of outputs and would have to rewire my ignition setup to use it.



So I went with the AVC-R and at first was very intimidated by it. I spent a Sunday Morning in an industrial park playing with it after reading the manual 3 times. Then read the manual again while tweeking.



I am not gonna go into all the AVC-R does but lets just say I have TOTAL control of where and when my car boosts now.



I have an A setting with a low-high-low setup for the street. I have a B setting with a High setting across the board for when I finally get to spank one of those new C-6's. https://www.nopistons.com/forums/pub...DIR#>/wink.png



Then I can shut it off all together and use my wastegate spring.



I can switch btween the 3 very easily. The AVC-R is rock solid.

i have the profec-B and i have it programmed with low 10lbs and high 14lbs . it wasn't hard to wire up and wasn't hard to progarm either . i wouldnt trade it for anything except the apexi-avcr only because its even more programmable, digital and matches my s-afc .

HKS EVC..awsome fuzzy logic.

I didn't know you could do that on the 1st version. Damn!

This is in the same vein of discussion, who uses the Haltech boost controller?



Is it not possible to have extremely customizable maps that would be superior to any of those other boost controllers?

It sucks!

I had to mess with both the E6K and E11 boost control, and it's horrible.

I don't know why Haltech doesn't just program a closed-loop control where you just punch is the boost level and let the PWM solenoid control it.



In reality, the actual control is nasty.

Although you do get a 2D (versus RPM), 32-points boost map, it might sound better, but it's a royal pain in the ass to program.

Even when you get it going good, it doesn't do a very good job of control.

Overboosting is almost guaranteed.

Because it's dependent only on the duty cycle programmed, ambient climates can change boost levels depending on humidity and temps.



There are Haltech owners who use the boost control inversely and run it as a restrictor.

Thus, lower the duty cycle the higher the boost level.

They claim better boost control (i.e. more aggressive), but the Haltech has a "safety" feature that would automatically default to 5% duty cycle if you hit a preset amount of boost - in this case, the safety feature would cause the turbo to overboost more, making this safety feature totally useless in this case.

You just can't win. :(



In the end, I always tell my customers to go with an aftermarket EBC.

All of them are happy when they went this route.

Wow, thanks for the info Ted, I think I'll probably look into getting one once my car runs and I get used to driving it!

It depends on the application.

For those that are street driven the EBC is the way to go for convienience. The top 3 IMHO are the Innovative and the AVCR and Profec B tied.

As for drag racing, the ONLY type Ive seen on HIGH HP cars are the MBC, a simple $20-40 item from sears or home depot. Because it flat out works, you set it and forget it.

I have a ball and spring MBC...it's good, but I'd like to keep the WG shut until the point of no return. I can hear the WG open up a few psi before it's fully open.



Electronics is the way to do this...springs just can't.



I like the ease of the MBC. Two vacuum lines and no wires or solenoids or boost sensors. Very clean and reliable. That's about the only advantage I can think of.



I don't see an EBC making my times at an AutoX event any better, so I'll probably stick with the MBC.

what would be better for a single turbo weekend/drag strip fd? Manual or electronic, and why. thanks.

blitz sbcid. set it and forget it.. works amazing https://www.nopistons.com/forums/pub...IR#>/smile.png

Manual, so simple clean and easy to do, almost as reliable and ebc.

i saw quicker boost with an avc-r than i did with just the wastegate not to mention being able to flip from mode a to b instantly...

Cant you just get the 2 stage mbc from turbo xs for that.

I like a mbc.

"Cant you just get the 2 stage mbc from turbo xs for that. "





That's what I use. You can change back and forth anytime even under boost at WOT. I had the AVC-R but I like the ease of my dual stage MBC.

This is the one I have , its one of the best so far ! , much better than the more expensive HKS or Greddy.

DuMaurier 7,

How do you like that e-boost controller? I was looking into it and was pretty interested. What kind of boost are you pushing? If not the e-boost controller then I'll probably go with the Innovative MSBC-1.
