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.
