I've got an Avanzato TRXX l2s
i've installed a safc 5 button and hks evc1. My problem is the boost is either maximum or minimum. For example (in manual mode) my boost will cut when i turn the button on evc1 it will cut(the boost is 1.1 over) and if turn down it will only 0.7bar (minimum bar). (in high mode) when i set the boost to 1.0bar the boost will go up and down(at the boost meter). Up and down means that the boost go to 0.9 then 1.0 then 0.8 then rotating them. The needle of the booost meter is shaking.Is it because a hose leak or because of my actuator?or something else?
Thank you
Hmmm One of these controls
Hmmm
One of these controls is an advanced engine fuel control and the other an overide which toggles the wastegate thus engine boost.
The sfc allows you to play with the fuel mix ratios, knock levels and a host of other engine specific settings. Which unless you are an automotive engineer in F1 will be meaningless.
The other designed to save the engine from detonation because of Turbo "creep".
If you intend to go circuit racing then I can see the need for these units but if you are cruising and posing they are a hugely expensive and a wasted toy which if you get wrong could be very expensive to rectify.
Did you set the controls up on a rolling road and have they ever worked OK?
Contrary to what you have been told these units are not just plug in and play.
My advice would be get thee to a tuner with a rolling road installation and let them set things up correctly and safely. Not cheap but better than a detonated engine...which you can still do as you have control over all the inbuilt manufacturer's safeguards, this way to engine rebuilds, burnt out pistons, trashed turbos...

I buy the the hks evc1 2nd hand from my friend. yes i tried in a rolling road. When i set to 1.0 bar. When i rolling from gear 1. The boost is standard (0.7bar) until it reach rpm 5500 it will go to 1.0 bar with the shaking needle boost meter. But when im flooring on gear 3 when rpm 3000 (3000-4500 0.7 bar) the boost will go to 0.7 bar until at rpm 4500. Is it normal or the hks evc 1 can be set like an apexi avcr that can control boost trend to rpm?
