How many people are using the Hydra on the STi?

Quick · 09-30-2005, 03:41 PM

and what are your mods??

I'm trying to decide on what direction to go in for a stand alone and being that I would like ot maintain drive-by-wire, this is one of my limited selections..

So, speak up and voice your opinion..

Im running the hydra w/wideband. i have sz55 turbo, fmic, 816cc injectors, and rest of supporting mods. I am very happy with the hydra, it is a smooth system. no problems so far.

Running Hydra w/wideband, lovin it.

+1 for me. But I pretty much only have an intake and TBE so far. My money gets spread too thin to get my car built up too quickly. Hopefully next year the turbo upgrade will happen.

I have intake and TBE also, and thinking of going Hydra, can you not keep drive by wire??!

I think he mention DBW just because some other systems (AEM for example) haven't made a DBW version. So Hydra is one stand alone that works with DBW.

05 STI, Hydra powered. I have also owned the UTEC and Cobb Acessport/Street Tuner but in my humble opinion the hydra exceeds the capabilities of the others, bar none. The only regret or issue that I have is that the Hydra does not have OBDII support and cruise control.

Mods are:

Ultimate Racing GT35r (.82 A/R) turbo kit with coated piping.
APS DR725
APS Tumbler Deletes
APS 3.5" exhaust
pe850's
Hydra with wideband
Dual Supra twin turbo pumps
dual HKS BOV's
....a bunch of other parts.. DEFI BF's, Alpine IVA-D901...

Loving the Hydra, although I haven't quite figured out what I'm going to do come emission inspection time.

Yes, the idea is that I would like to maintain DBW while having full control over the motor. That really only leaves me with the option of the Hydra or a Motec with a custom built harness. As this isn't my daily driver, i'm not concerned about OBDII or emissions.

My goals are 400whp on pump and race-track proven. A stand-alone seems like the only real solution for full control.

Trying to hash out management solutions first as that greatly changes my route..

Honestly, that new Z06 is looking very appealing as the cost of this car starts to add up...

You'll need to borrow/buy a UTEC, Xede, EcuTeK reflash, StreetTuner, etc..

My factory ECU has a reflash that is "close enough" for my mods, so if I ever need to get my car inspected, I just need to use that ECU long enough for it to pass all of its tests before it goes in for testing.

Just reinstall your OEM injectors and plug in the stock ecu. You need about 4 drive cycles to set the readiness codes which takes about 15 minutes. It's best to do this on the highway as you need to be above 50 mph for about 1 minute, pull over, and turn the car off. Do this about 4 times and all readiness codes should be set but 1 (evap emissions). This doesn't matter as your allowed to have one not set. Just stay out of boost and the OEM ecu will be happy.

Hydra continues to be revised and have new functions....now I just need to get Joey to give me mine back....oh I don't have a car right now.

It's not quite a plug in and run thing, but it is very sophisticated and a lot of fun to learn how to tune every aspect of your car. For the owner-tuner I don't think there is really anything else to own. It's better than the stock ECU can be.
