    in competitions trophy l electronics ? the original and deleted all the strategies employees from anti-pollution rules or statutes of limitation for the production of power, but I do everything with the electronic original.

    Adjust a turbo that is different from the ori will be very difficult for me to avoid problems, I opted for a mechanical adjustment with tap etc..

    I know that ? a boring answer, but ? difficult only for those who has not the knowledge to do that?....l alternative of the mechanical adjustment ? a viable alternative

    if you look in my first message on this topic I wrote exactly this, and also for those who have knowledge are needed many attempts to develop variable geometry and PID.

    The answer is very obvious the knowledge they are there, but without evidence, on paper I don't think that we can, sandro, I agree on the difficulty? I have a hard time thinking of off the controller...

    What it means to enter the surge? And as I notice it?

    quote from wikipedia

    "... the limit of the speed? maximum ? imposed by the fact that if the output of the vane is reached, the speed? sonic, we are faced with the wall of sound (or cone Mach), which is a pressure wave that is s? that the flow of fluid is pi? or less intermittent. It is said that the compressor has reached the limit of pumping (or surge limit or surge flow in English). The disequilibratura apparent of the impeller derives precisely from the fact that the pressure on the headstock not ? uniform..."

    to recognize search some video on youtube, the ones you will find are extreme cases, when you get close to or enter little surge does not have these effects and not be able to hear it, you realize why? the turbine perder? the balancing in a short time. To avoid this you should be trying hard well the compressor map and turbine mounts, but they are rarely...

    Warranties a lot!
    Something like this? But as shown on the maps?
    I think it takes skills and studies to the shoulders of a certain ****llo not ? thing for simple hobbyists...
    Instead, the choke line that means?

    you, like the one posted, the chocke roughly refers to the limit of the turbine on the turbo car, it has the high speed and reached the threshold speed? of the turbine shaft can? increase, while the boost pressure rises slightly. for? this ? the less dangerous of the surge, even if it increases much wear and tear.
