Alright, I bought one of these, installed it, its working great, but I can't do anything past adjusting the boost level which is weird as hell (going by % instead of PSI). Also, I can switch between high and low, after that, the instructions just lose me.

Is there anybody that can give me the "EBC for idiots" version? What do all these options do and how do I use them? Its not that I'm lazy, its just that I'm stupid.

 

i just recently figured mine out.
search and search...that being said...

heres a starting point but you will have to adjust slightly of course.

take 3 times your wastegate springs rating, mine is 7.35. Lets just say 7.
so I get 21psi max boost so to speak.
now back to basic algebra: what percent of 21psi is your target boost? lets say you want 14lbs. x(21)=1400
therefore x = roughly 66.6 repeating, lets say 67%.
I would start your set boost at 35%ish and work up just to make sure you dont zealously overboost. This is just how I came to tune my spec B. Set boost is the actual duty cycle % of the boost solenoid.

For gain I just started at around 10ish and eventually played with it until i was around 19 ish. if boost is erattic(spelling?) then lower gain, if boost falls off during a full boost pull then raise the gain. Note: raising gain raises boost despite the set boost setting. Straight out of spec b manual. Gain is just response so to speak, but its a weird measurement. Its in relation to duty cycle of the boost valve when not full boosting.

Start boost I went to from about 8psi below my target boost to around 3.8psi from my set boost. You want start and set boosts to be fairly close but start about 10 away or so if I were you. This is when the wastegate starts to burp out excess exhaust.

I then proceeded to set my warning to .2psi below my target boost, my limiter to 0% because I dont want it to limit at warning because its .2 below my target. if i had the warning at say 2psi above the target boost, then id set the limiter to say 20% or so. But don't take my word on that, because i just run the limiter at 0.
Turn last boost on, it makes tuning this damn little thing much easier.

and in closing you are lucky its late and im tired and reading around anyways. Because I came to this conclusion that I am typing you right now three weeks ago when I searched the boards. But it is a confusing subject and I felt I'd lend a hand. cheers
