I wanna get my mbc put on but wanna wait to get a tune done until i get a few more parts. any input?

 

if you wanna install the mbc, keep the setting on lowest until you are ready for that tune

 

Hi boost + no tune= boomm!!!!

 

Whats the point of putting it on if your still waiting for parts?
Put them all on at once, get tuned and be done with it

 

You'll get knock is what you will get. I don't understand why anyone would use MBC anymore to be honest. It's like trying to use 2 decade old technology on your newer car. Doesn't make sense when the other options are cheaper and better. To each his own i suppose.

 

Thanks guys. And the reason for using an mbc is the boost is what you set it at where an EBC adjusts to conditions.

 

EBC is crap too. ECU controlled target boost is where we are at now.

 

il look into it!

 

ECU boost isnt for everyone. Tuning ECU boost can be kinda complex and the end user may not know how to lower and raise there boost if they need to (like if they add parts, and boost starts spiking and/or oscillating. OR if they need to lower boost for some reason)

Also, ECU boost isnt cheaper. To have proper ECU boost you need:

- A 3 port solenoid
- A MAP sensor

Then you also have to:

-Mod the ROM for the MAP sensor
-Mod the ROM for PSI based boost.

And last you have to tune it (which take a good amount of time more then a MBC).

To some people thats a lot of work compared to the install, set & forget style of a MBC. Also, the cost of a 3 port and MAP sensor is more expensive then a MBC.

Yes w/ ECU boost you will be able too hold more boost from 5Krpm-redline and you will/can make about an extra 10-15HP&TQ in that area.

But to some people that 10-15 HP&TQ up top just isnt worth the hassle of ECU boost.

Also there is a handful of ways to get a MBC to hold more boost from 5Krpm-redline and gain that same 10-15 HP&TQ.

Yes, there is other benefits of ECU boost, like being able to switch boost levels/profiles when switching maps. Also there is the stealth-ness of it.

But still, for some people, a MBC is just fine.

 

thanks boosted

 

You'll also whack off your fuel cut if you go too high.

There are other ways to do stock ecu boost without a GM 3-port while using the stock BCS...bleeder valve in between the turbo and the BCS works too while helping to cut down on oscillation, but you do have to remap all the boost control tables.

 

+2-3 PSI was fine on DSMs ..I dont see why you could not do that with evos ( with Intake and catback atleast ) running higher octane mix of 93 or higher is preferred.

To be honest, if you go over 1.2/1.3 bar you WILL get boost/fuel cut. If you get that removed, but don't get a proper remap, then you AT LEAST need to get fueling & knock checked.

Upping the boost without a remap won't instantly kill the engine. If the AFR's are good and knock count is within reason (occasional knock counts of 2-3) then the car will be perfectly fine with the upped boost, but obviously to make the MOST of it you need a remap. Personally, in your position I would fit it and keep it at stock boost (1.0/1.1 bar), then fit the rest of your parts when they arrive an take it to get properly mapped at your desired boost level.

 

GM 3port ftw.

 

just do it and see what happens!! then we will all know!! j/k
