can anyone help me out? pros/cons of each one?

 

manual controller has only a few vacuum lines, like 3 in total that can be run anywhere. (best not to have it in the interior, makes a loud hissing noise).
less precise, a lot of guess work to find your ideal boost pressure, max boost pressure you ca get out of it is 25psi so far from a few of my friends experiences.

electronic boost controller has several vacuum and electrical lines going places, can be mounted anywhere (depends on which one really) some have a built in fuel controller, boost mapping (like the greddy profec E01), cost varies depending on what you want out of it, some also double as a turbo timer
more reliable, more precise, replaces old solenoids and some even replace the MAP (if equipped) sensor for one with a higher rating


it all comes down to:
cost, preference, what you want out of it

 

Dunno about more or less vacuum lines, but they should be rigged just about the same.
My A'PEXi AVC-R only has two - one from the turbo and the other to the wastegate actuator.

An MBC also changes boost depending on temperature and humidity.
An EBC with a dedicated MAP sensor will not do this.

RETed is right, electronic boost controllers are kind of set it and forget it type of controllers. I do need to adjust my Hallman manual boost controller when a cold front comes in. The way I get around always having to adjust it is by setting the controller on a cooler night. When it is warmer out I yeild about a half pound of boost less than I would on a cold night. This is probabaly annoying to some, but I do not mind it. I guess it all comes down to how thick your wallet is.

 

the mbc does not get affected by the cold weather, if you are using a stock internal wastegate or a cheaper external wastegate that is where your boost vis affected

 

Uh, wrong.
Thank you for playing.

Even an (non closed loop) EBC gets affected by cold weather. On some setups MBC simply does not allow enough control for a flat boost curve. EBC is definately worth the money.

 

on a lot of EBC's you have to tune the solenoid duty cycle. otherwise you will get spikes or excessive lag.

 

My profec has three vacuum lines. Two for the wastegate/turbo and one to the FPR. One harness to the unit from the solenoid and a harness for power. It took me about 15 minutes to install. I think mine was like $200 or something brand new, so it's worth the investment, I'd say. Plus it has a built in boost gauge, so that's bonus points.

 

thanks guys! i think im going to go with an electronic controller. anyone try the greddy profec type s controller? im looking into that one because it just has a few *****. i just need to set a boost and have the ability to adjust is as you guys do under different conditions (weather, track ; etc) ive been told manual controllers can lower themselves? meaning that under vibration and whatnot, the boost level could change on its own. i dont know if this is true but. THANKS for the help!
