Turbosmart Electronic wastegates

Hi All

One of my projects has a Honda K24 engine that I am turbocharging... its a track only car and the idea of the package is to make the engine feel NA and be as responsive on part throttle as NA so that traction can be balanced on the throttle. Basically have the engine make NA power when running zero boost and tickle it at the higher rev range (Im expecting around 10psi max boost).

To that end I have broken from the 'norm' and am going to run a very large turbo (for the power target) to reduce back pressure when running zero boost and I will be using a 45mm Turbosmart Electric wastegate... I can then have zero boost targets on part throttle and any rpm and bleed boost in very gradually (1psi at a time)... Ive done a similar thing on another project using very soft springs in large external wastegates to good success so wanted to take it a little further this time.

To power it I have a Fuel Tech dual power driver and an ECU master black ECU but as its relatively new tech here in the UK I don't know of anyone who has run electronic wastegate control... on paper it should be simple right lol

The ECU master Black does have options for electronic wastgate control and the ECU was already CAN configured to work with the donor cars electronic (abs, power steering, dash all don't work without ecu CAN to say engine is running) so it was a sensible start point, however in truth i can't exactly get my head around the best way to control it in the software. The ecu seems to put the EWG target against Backpressure?

Has anyone any experience or words of wisdom or advice they can share with me about settings in any ecu's to control these new wastegates?

Many Thanks

Andy

Hi Andy,

Did you get this working? I am building an Abarth at the moment where we have chosen the Turbosmart 40mm electronic wastegate and the car already has a EMU black and am embarking on the same journey.
