Davehahn Posted January 17, 2022 Report Share Posted January 17, 2022 Im looking to purchase e wastegate ang my question is the link ecu capable of controlling egate ? i would think it is possible being it is similar to dbw Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 17, 2022 Report Share Posted January 17, 2022 No we dont have support for electronic wastegates at this time. G4X will likely get that functionality in future but unlikely G4+. Quote Link to comment Share on other sites More sharing options...
Davehahn Posted January 17, 2022 Author Report Share Posted January 17, 2022 Ok thank you. I can’t wait to see it available for g4x I’m going to be running a k24 turbo in a dc integra Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 17, 2022 Report Share Posted January 17, 2022 Unless it is going to be something extreme I wouldnt bother with an electronic wastegate in general, they are slow, give poorer boost control and several other fundamental issues that make them 2nd choice to pneumatic control for most applications.

ytubit Posted June 6, 2022 Report Share Posted June 6, 2022 hi @Adamw, when you say they have some issues, are you referring to all e-gates or just the oem ones? The turbosmart egate works pretty well i’ve been told. Have you had any experience with the turbosmart ones? As link seems reluctant to give us a way to have push/pull type boost control i had intended to use an egate instead but alas link doesn’t support these either?

Adamw Posted June 6, 2022 Report Share Posted June 6, 2022 Yeah I have used both the turbosmart one and OEM ones. Both are significantly slower than pneumatic so control is poor. I would only use the turbosmart for something like a promod where you have a lot of turbine inertia (so dont need real fast response) and need to do some unusual control strategy at staging or launch that cant be done with pnuematic. The OEM type electronic gates we used at my last job for a category of identical F4 single seaters, in this case we went electronic to reduce risk of the teams cheating. We had to do all sorts of software tricks (Motec M1's) such as auto recalibrate the position sensors at every start up and software prediction of boost rate of rise etc to get them to work acceptably but even then boost control was not as good or repeatable as the conventional pneumatic system. I believe Turbosmart now have a black box to allow control from a conventional ECU PWM type boost signal, but I would only go that route for very specific applications.

Any idea when link are going to do what every other ecu manufacturer does and give us a push pull type boost control? cheers Quote Link to comment Share on other sites More sharing options...

I guess by that you are referring to "CO2 boost control" or "dome pressure control" with two solenoids like an AMS does? We added this type of dome pressure control to G4X a while ago. Wont be adding it to G4+ as the firmware is maxed out already and it is a fairly substantial resource hungry function. Quote Link to comment Share on other sites More sharing options...
ytubit Posted June 7, 2022 Report Share Posted June 7, 2022 bugger, that doesn’t help me much seeing as the vehicle in question has a thunder in it. Quote Link to comment Share on other sites More sharing options...
