So next question that I can't seem to get answered on any of the Hydra EMS sites...

If I just went and bought a Hydra EMS w/ the wideband O2... can I just plug it in and be able to drive my car for a while (at least til I can get it to a tuner sometime down the road)? or will it run like crap unless I tune it?

becasue I'm busy w/ work on the weekdays, I want to install it one weekend, and then take it to the shop on another weekend. will I be alright this way?

BTW, this is my planned upgrade path in terms of power...

1. Hydra EMS
2. injectors (800cc?)
3. downpipe? (are the stock ones terribly inefficient? I'd like to keep the car as stealth as possible)

depends on the map that u get.. for base maps u should be able to drive around with not much load. It should be relatively safe (low ign, rich fuel).

Can I ask why change injectors to 800cc w/o turbo mods? or u've got a gigantic turbo already?

The best advice is to just call Phil at the number posted. You will be able to get all your answers much more quickly that way. And he will probably even give you some answers to questions you didn't realize to ask yet too.

I didn't want to bother Phil w/o exhausting my resources on the forums and searching about it first. I'm sure Phil gets a lot of calls with questions that could've easily been asnwered by a quick search or question here on the forums... just being courteous on my part.

As for the injectors, I read on the element tuning site that their injectors were running static at 5500rpm... or was that for the WRX?? well, injectors won't be done unless the logs show that the stock ones are insufficient. I'd like to keep injectors at 80% load or below. I do plan to increase boost a bit, but only on track days, and I don't think I'll ever upgrade the stock turbo until it's either in need of replacement or when I'm done w/ all my suspension and drivetrain upgrades.

We have great base maps for the STI using stock injectors with a TBE and for the same with 800 cc injectors. Our maps go all the way up to 65 lbs compressor turbochargers.

For your current modifications and as long as you follow an Element Tuning recommended modification path, we have maps that you'll be able to drive around without issue.

In the warmer months you may not max out the injectors but I guarantee they will be in the 90% range if you run around 11.0 AFR.

Thanks,
Phil

Phil,

Thanks for your response on the thread earlier. just wondering, if I wanted to get the Hydra w/ a wideband O2, do I just plug it into the stock O2 location? or will I need a separate bung welded somewhere?

Also, how much would it be to purchase everything I need for the install on my 04 STi?

It will come to just under $2k shipped. And yes the stock O2 location will be just fine for the new wideband.

There's no need to install and use the wideband until ready to tune the car. It will also save it's life a bit. Unless the base map you receive is setup to use wideband, you will have to use it, unless you know how to work around in the Hydra and disable the wideband usage and AFR Target Table or ask Phil for support on how to do it.

If you are running stock turbo, there is no need for 800cc injectors. The most recommended path would be to use a TBE, increase a tad of boost and the Hydra.

Then you can do, fuel system, turbo, more boost and other routes.
