You need the n75 valve, can use the one that was controlling the egr valve. The 110 ecu is exactly thesame as the 90bhp one, just has different maps, any decent mapper should be able to enable vnt control on the standard 90 ecu afaik.
Lol, you have obviously never driven / rode in a diesel with a VNT on a boost can then? Comparing a td04 to a vnt on a boostcan is like comparing a 1.1 TU to a gti6....
Running an ECU does help with surge / mpg and easier on the turbo during cruise..but it wont make mower power, or spool up any faster. They are a monster to drive on a boost can just as they are on an ecu...once you run a VNT you will never run a WG turbo ever again. Its certainly not pointless / might as well run a td04....
Why "waste" excess exhaust gas past the turbine via the wastegate when you can just run a turbine that can flow more gas in the first place and "close up the vanes" to utilize the turbo in the lower revs....
Watch my audi v6 mtdi / 306 mtdi build videos to see how I modify the boost can, takes 5 minutes, and works perfectly.
