Opened loop or Closed loop boost control
 

should I go Opened loop boost control or closed loopt boost control...

Can anyone tell me. which one is more for the performance and how they different???

You want CLB.. In open loop boost you are setting the solinoid duty cycle, in the closed boost map you are setting a target boost and the utec will change the duty cycyle to hit that target boost..

hmm.. so which one is better for power???

Personally i would use CLB..

On manual, to use CLB, "install the optional map sensor" what is this?

I need to buy something?

Its a GM 3bar boost sensor.. I think the manual has the part #'s required for making it yourself, or you can call TurboXS and have them send it to you. The MAP sensor is definitely worthwhile regardless of if you use it with Closed loop boost or not.

Yea Map is a big Plus!

Plus, you can new vent your BOV!!!! Isn't that exciting???!!!??hahaha..... By the way, anybody has any experience with a Map sensor for the utec? I'm getting my utec soon and looking forward to swap the MAF for the MAP sensor. Any help would be greatly appreciated.

Umm... You're not swapping the MAP for the MAF you run both.. The utec is not a speed density based EMS "yet"

Yep, Spec C said it.. Currently the UTEC doesn't do a speed density conversion. I am fairly certain we'll see it at some point in the future..

the MAP sensor at the moment gives you the ability to log your boost pressure, and work with closed loop boost control..

However, at the moment, although you can use the MAP sensor for the reference signal for the tuning, it is not yet capable of removing the MAF sensor and running without it.

Loggin map is BIG in tuning.. It really lets you get into tuning for spool up and low end.. You can run quite lean on low boost situations for optimum gas mileage for crusing and to keep the heat in the pipes:p
