Don't want to sound daft but is it possible to retrofit these to standard 'v' (not gtb) turbos?

looks like a very fast and precise system to me!

should be possible, but these electronic controlled turbos use a longer lever, in theory you could just limit the duty cycle range in the software to overcome this..

also remeber you don't have a stopscrew, to you need to limit maximum vane closure precisely also in the software..

Everything is possible! But the benefit is not that much... A faster closed loop is a nice feature but not so important.. also because its not that much faster . OEMs also use this type of actuator because of more precise feedback and temperature/error return.
And of course, if you use it on old EDC its only plug n play with hardware..
There is a lot to do with software! Rub already mentioned the missing stop screw thing and there is also precontrol/PID Maps of governor that must get adjusted heavily...
Normally, on newer EDCs you have a special map for max duty cycles in relation to rpm and mg/str.. this is more or less stop screw map...
dont know how to fix it in EDC15 for now .....

you can do it maybe with the 16x1 limiter map?

don't know the name, but you usually find them slightly above the boostmap(s), rpm vs duty.. you have 2 of them, one is min duty, set a 5% (95% in vagcom) everywhere, the other starts around 75-80% and tapers down at higher rpm to prevent excessive van closure at igh rpm..

but you are right, I also do prefer the 3d maps as in edc16

Thanks for the friendly responses!

Software isn't such an issue as I'm using an ancient ecu - it'l end up being a homemade controller just like this lads mosfet setup except with the control routines and sensors too - just wondered if it could be bolted on as I have limited space for an actuator, it fits but it's too close to my car's driveshaft for comfort.

Might be something to look at good stuff keep researching

Ah... 72E18 and 72E5C n Audi A4 ols... Didnt know about that...
But a limiter which depends on load would be better as an over all limiter...
i have to measure duty cycle for a minimum vane gap. and set it as max limit.. but why to liit in the other direction?

not real use in other direction unless you want to keep vanes closed for what reaosn so ever

Does anyone know the function of the 2 remaining pins of the hella actuator? My scope died so I cant verify it.. 3 or 5 must be feedback or? 0-5v or pwm or..?

is this thread dead?
or is there another which solved the electronic actuator issues for edc15?


cheers

why does there need to be a mosfet? i would just run a prarallel resitor with comapreable resistance to the N75 coil, and then feed it direct to the actuator
