Electronic wastegate support?

Postby datsr20 » Mon Dec 07, 2020 5:01 pm

Was poking through the map software the other day and I don't see any indication that there is support for electronic waste gates. Am I missing something or can we really not use the H-Bridge outputs for controlling electronic wastegates? I'd love to get get rid of fiddly gate springs and 4 port solenoids to get a nice broad boost range and am truly surprised if haltech's top of the line ecu can't drive ewgs.

Yah I've seen the video, but I've not seen any word from haltech nor turbosmart about how they were controlling the thing. In the NSP I don't see any obvious signs of support nor do I see any documentation about how perhaps a generic table could be used to drive the thing.

Would be nice if that was documented and/or officially supported somewhere.

I spoke with a Haltech engineer about this...

While the Nexus does have H-bridge outputs you could utilize, they cannot handle the potential amp requirements of the valve. He also questioned the reliability of the valve itself and noted that any controls for such would be done with Generic I/O. i.e. no native support built in.

Lastly, he said it was more of a "Nerd Novelty" (his words) at this point as the development thus far has not proven it any better or more reliable than traditional setups.

Bringing this back up to ask further questions.

Amp requirements at 80psi are 18amps with the valve holding fully closed. They list 20amps as a "highest potential load" however they've stated normal operation of the valve should be 8-12amps in most cases. The nexus r5 can easily handle this, and they' showed it controlling the gate at PRI.

I guess now that these have been in production for awhile with the release of 40 & 50mm variants even, does Haltech plan to support this? I don't see the necessary functions in NSP to support it, but I've been seriously considering going this route. Turbosmart did discuss the idea of releasing a separate box to control it using low-side pwm from the ecu. I think this is a good idea for ecu's which don't include the high-side outputs like the nexus.
