Default Hydra = no cruise control right? Anything else?

I couldn't really find anything on the Element site regarding missing features when swapping out the stock ECU. I believe I read the cruise controls is out, yes? Anything else? DCCD? Air bags? What all does the stock ECU control other than fuel/timing/boost/other-engine stuff?

From what I understand that is the only thing missing. And it sounds like Phil isn't going to attempt to get it working again. Apparently he is very concerned with the resulting safety issues that a cruise control system on a drive by wire car has.

Cool. Do you know if the DCCD and airbags are controlled by the ECU? I'm just wondering how accurately the replication of those features would be. Might even be interesting to tweak the DCCD or add a yaw sensor to the 2004 (not that I imagine it is possible with current Hydra, does it have additonal external sensor inputs?).

Wouldn't you think that Subaru would have a more conservative attitude regarding safety than an aftermarket parts company?

I would to, but I guess that isn't the case this time.

Subaru is concerned with your safety but they use a separate computer for the cruise control where we would have to use the engine management computer. This would result in ignoring the pedal position while in cruise which is a safety issue since the throttle plate position would differ from the two accelerator position sensors. Normally when this happens a fail safe circuit is tripped in the Hydra as it would most likely mean a "stuck" throttle.

Thanks,
Phil

Thanks Phil. Any comment on how the airbags and DCCD work?

Non-DBW Hydras retain all factory features correct?

That is correct but remeber since there is no OEM computer there is no OBD2. All other features of the STI remain as they did from the factory, just no OBD2 and no cruise control.

Thanks,
Phil

Oh, so the CC computer is disabled with the Hydra, or is it just missing some inputs?

Only on the DBW cars, standard throttle cars retain cruise control.

DCCD is controlled by it's own logic unit. The airbags are controlled by little accelerometers that are part of the bag units, and replaced with the bag should it go off. Cruise is a nice feature that I've never had (can you believe that). I'll give it up anyday for the Hydra's flexability. OBDII would be nice for those States that use it, but I somehow doubt I could pass an emissions check by that mode of assessment.

Has there been any change with the cruise not working with the drive by wire cars?

Phil says no cruise unless you are using cable throttle.

Yes cruise control is coming. I guess never say never. LOL!

This will only be a 2.7 option and it's only an Epsilon option so it won't be cheap. Hydra EMS wants me to test this extensively before they release it to the public which means no beta testers.

Phil,

I'm under the assumption after reading this thread that my Hydra will soon be able to have cruise control?

Let me know what the status is on that as I am extremely happy to hear this. This was the main downfall for me with the Hydra and why I almost sold mine.

Thanks

Its still in development but its only going to be an option on 2.7 or newer and at this point there are no public details available. Its going to require additional hardware above even above the current 2.7.

Phil,

I don't know if you remembered me, but I got the car from the kid in Maryland that owed you money. I believe this car has the Hydra 2.7 Nemisis EMS. Please correct me if I am wrong if you can

Thanks

Yes and he's all paid up so no problems there. Yes it's a 2.7 but I can't tell you when we'll release the cruise control option or what it will cost at this point.

Where can we find the options currently included on the different 2.7 versions? (Alpha, Beta, Gamma, Delta, Epsilon)
