again, i am new to turbo's..and know very little about them. I purchased an MBC, and realy have no idea how to dial it in properly, AND, if i raise the stock boost settings, what else do i need to do? Just more octane, or is tuning involved? Or does the factory maf handle the tuning for me.

-completely lost dontrevme-

 

u got a boost gauge?

 

IF u use an MBC, ur def letting the boost hold till redline. How high u want the boost is ur choice. But u have must have a TUNE, if u jus drive without a tune- the ecu will still think its the stock settings- ( in other words ill jus f up ur car)

 

In route as we speak actualy.

 

You dont need a tune if your going to raise the boost 1-2 PSi. The AF shouldnt change much and you shouldnt knock if you put high enuogh octane.

If your GIng with a TBe and MBc then tune it..But with just a MBC with minimal adjustments you dont need a tune.

 

I have the mbc here, tbe/flash on the way..I guess im lost on the whole point of the MBC if it has to be tuned everytime you change it

 

Wait for your BOOST GAUGE to get to you.. It will help you not only tune and ideal boost but also for tuning..

 

You do not need to tune your car everytime you change your boost, tune the car for the high boost you want and you can always turn it down a bit, alot of people who have electric boost controllers have 2 maps that they switch from like 18 psi for daily driving and 22psi or whatever for there other map.

 

I dont plan on installing it untill my gauge is in, and i might wait for my tbe/flash aswell.

 

Finally a new guy with a clear head. At least your not rushing into everything and waiting for other necessary items.

 

i'm a new guy too.... how do i read my boost gauge i'm not sure how it works . i would say i'm in the same position expect that i have a boost gauge and will be buying a MBC very soon. i have a apex i boost gauge it read as any other boost gauge anyhow my question here is how do i read and understand it . people are talking about 19 psi and 20 psi how do i read that into my boost guage when it reads -5 ,0 ,5 ,10 ,15, and so on ..... keep in mine i'm very new this is my first turbo car.

 

If your new to turbocharged engines, you should get professional help for instalign a Boost controler, You can Potenionaly cause damage to the Motor or turbocharger.

 

Almost all Boost gauges have a measurement unit on them, like BAR or KPA or PSI. Many Times if you have a Boost/VAC gauge there are 2 different measurment units, one for Vac and one for boost. for a quickie 1 BAR= 14.503 PSI Vaccum is usualy KPA. The Stock Boost Pressure on the Lancer Evolution is Aroun 19 psi at 3500 and tapering down from 4200 rpm.

 

here is a pretty straight forward calculator for KPa, Psi, Bar http://www.csgnetwork.com/metpressure.html

 

So I was Right, I don't think his needle is Accurate enought to tell .001 of a PSI.
