When my car had the rebuild done the left the boost controller unplugged so as to not void the warranty. What i want to know is whether or not i should plug it in. Is this one any good or will i get any benefit from it. I know it's an older model that's why i'm leaning towards just getting rid of it; that and the fact that i'm not sure how to work it. just wanted to get some more knowledgeable opinions.

If you are on stock ecu, leave the boost at stock levels.

 

hmm... Looks like HKS EVC I or EVC II. This is a pretty decent boost controller. From my understanding, the older BCs are quite good. The GReddy Profec A (first gen Profec) is among the best around, still. Besides, its already there. Why dump it? Keep it, you'll need it sooner or later.

Joe... also...

 

profecA's are very bad times unless you have consistent boost...

 

Translate into english please...

 

How did the Profec A get into the question he's asking about his HKS boost controler ? ? ?

 

why wouldnt you hook it up? I mean its just added security that you wont over boost...

 

This would be incorrect. When unhooked he has (or should have) minmal boost if no pills are involved 7psi. and if he hooks it up and adjusts it incorrectly he can actually over boost the engine and that could cause a problem. Remeber it is a boost controler and will adjust the boost not prevent it from over boosting.

 

so far i'm thinking i should leave it and not hook it up until i have a need to modify the ecu, correct so far? Also what do you mean by pills, cant go straight?

 

The Pills are lillle (like carborator jets) plugs with a spacific size hole drilled in them for setting the wasegate and precontrol pressures. Smaller = higher boost pressure larger = lower. That's why when they are removed completely you only make minimum boost (7 psi) the boost controller replaces these PILLS and by adjusting it gives you the abillity to change your boost settings. People that don't have boost controlers but need to change there pre spool and waste gate chnge out these pills to do that. Most people that do it that way actuall use holley carorator jets. jack
