Default is the abc for the utec necassary?

i have been seeing various people controlling their boost with their sbc-id while having the utec installed. i've got an avc-r installed and would like to know if i need to install the boost controller which comes with the utec or i can leave it out and adjust boost with my apex unit...

thanks,

-soon to be utec-equipped salvatore

Why do you want to keep the AVC-r when the utec can do the same kind of boost control? I would sell the AVC-r and use the utec to control boost.

well, besides the fact that i don't want to always be on boost everyday and i would have to adjust the utec controller all the time where i could easily adjust boost with the apex unit right in front of me. i installed the avc already and don't want to remove it and have to sell it.

i am asking if it is necassary to install the utec abc and can i just have the avc-r manage boost since i know it pretty well.

thanks,

The ABC is not what controls boost with the Utec. It uses the factory boost controller. You can use your AVC-r with the utec but your going to have to work around the load sites.

The abc is used to help out the stock boost controller reach higher boost levels and fine tune peak boost.

Lets say that I that I am a retard and wanted to run 19 psi on the stock turbo. The factory boost controller would not be able to do this so you go a few turns out on the ABC and now you can reach that high.

Lets say that I am running 15 psi and don't want to bother using a computer to tune the utec to get 16 psi. Instead I can use the abc to reach a max 16 psi.

The abc has also been claimed to smooth out the boost curve too.

its also a good thing to use to change peak boost to match altitude and temperatures.

on the utec, you can go back to stock parameters on the
fly if you get a remote switch.

k, but i could go over 15psi with the avc and since it's rpm adjustable, i could smooth the boost curve as well...

i really don't want to lose the avc since i have it already and trust it very much since i have been tuning for a while.

thanks for the help!

you can go into 18psi+ range by just adjusting the ABC if you wanted (not recommended on factory turbo though).

i kinda think having 2 programmable boost controllers is kinda overkill, but that's just me. i guess the benefit would be that you can control ABC parameters from inside the car....
