My pulley's set for 9psi. My boost gauge shows 9psi. Why does my Hydra log peak at 6psi?

It matters where you have your vacuum line connected but typically as long as it's not part of your boost controller it will work. The Hydra reads in absolute pressure so it will typically read 1.5-2 psi less than "gauge" mode.

LetItSnow · 11-02-2010, 12:08 PM

Is there any way to get a more accurate reading? Options I can think of: Shortest possible MAP hose, hose of different material, external MAP sensor, different or more isolated manifold pressure source, altering the reading in the log with a formula (linear or exponential or... ???).

All told, I don't use it for a boost controller of any sort, but it would be nice to have a good reading if any is available, yeh?

Element Tuning · 11-02-2010, 01:43 PM

An "Absolute" reading is the most accurate means it's just different than how a boost gauge works. Now my Eboost2 is within 1.5 psi of my Hydra and both are using the same boost/vacuum source directly off of the intake manifold.

Where are you getting your source and is anything else attached to this line?

LetItSnow · 11-03-2010, 12:54 PM

I took a look under the hood, and here's what I found:

The boost controller is on a completely separate line from everything else. GOOD!

These are stemmed from a small port that goes into the side of the rear passenger side intake manifold runner (in order) Hydra MAP, boost gauge, fuel pressure regulator.

All told, the boost gauge and Hydra MAP hoses are both T'd off of the same line just inches apart, and under sustained conditions should be subject to the same environment.

hey phil just wanted to say thanks for the great customer service and all with my 07wrx hydra ecu..

just wanted to touch base with you. i know we had some issues with the programing with the 07wrx but we got it fixed with the idle and all. you said that there might be a patch for some of the issues and that i might have to send it in to get them fixed or patched? just wondering where hydra was at with all that .

also ima go with the 800cc injectors like you recommended to me to max out the vf39. just wondering what ones should i get????

You're welcome. On the early 2.6 flash there wasn't enough range in the dbw idle circuit for heavily modified heads so I had Hydra increase this. The other thing I recommend during the tps calibration is to increase the closed pedal cal by 2.

chochocho · 04-30-2011, 11:04 AM

hey phil,

looking for some guidance and suggestions.

hydra 2.6 installed in a 91 legacy ss. originally, the tuner that i use here in the bay area was having trouble getting the initial map to the ecu.

well, he finally got the map to the ecu (different serial cable) but the car still won't start. got another initial map from you and it still won't start.

he's reinstalled stock ecu for testing and though it runs like crap, it starts up. the hydra won't start. tuner is at wits end with the hydra and so am i. not quite sure what to do at this point.

any suggestions?

phil, i sent you an email as well for suggestions.

thanks.

I've read somewhere on the forum that the 2.7 version will have the ability to connect Ford's flex fuel sensor (for e85 mixed with gas). Is this correct? I'm also curious as to when this new version would be available.

Element Tuning · 05-18-2011, 11:03 AM

We've been selling the 2.7 Hydras..shhhhhh. LOL! We're already sold out and I haven't put the word out because demand has been high. I've been using it for quite some time and it's really nice with a big push to make it more "windows" like and easier to tune all while advancing it's features such as on board data logging and as you mentioned an option for a flex fuel sensor.

We've also introduced a lower cost/less feature version for cable throttle WRX and Impreza owners starting under $1300. The lastest Hydras are user flashable so you can purchase upgrades and load them yourself, upgrade firmware, etc.

Okay, let's hear it! It's past "close to release time"!

ZeroDrift · 05-18-2011, 11:38 AM

Great! Is the 2.5 version upgradeable to the 2.7? If so I would greatly appreciate a PM with a price.

Also is this OBDII compliant?

The new DBW control system isn't at all compatible with the older circuit boards so to upgrade a Gen 1 DBW 2.5 Hydra can be very expensive.

The OBD2 system along with CAN bus is an option on the highest level of Hydra....expensive but as I've been told it's not to be emissions compliant. It's just a way to stream Hydra data to the OBD2 port.

For the OBD2 port to remain fully functional we have another solution you can purchase which allows you to run your OEM ecu therefore giving you full access to the OBD diagnostics, flashing, etc.

I don't have the time totally get into this today but here's a screen shot at least.

Just remember not all features are available at every price point but all units can be upgraded to any level when your budget or need allows.

My impressions overall are great and there have been very large improvements on all the closed loop control functions from fueling to AVCS. The boost control system got a total revamp for the better also.

Joelo_00 · 05-19-2011, 08:54 AM

Is the new software is more Windows 7 oriented?

I've yet to upgrade from XP on the laptop that's used on my car since it works so great!

Element Tuning · 05-19-2011, 02:45 PM

Yeah it installed on my Windows 7 machine without issue. Windows 7 still has problems with USB-Serial adapters however and only FTDI chips have the correct driver package.

john 1badSTI · 05-19-2011, 09:00 PM

phil I thought you sent me a pm with a price to update my 2.5 04sti dbw box to 2.7,now you are saying it isn't doable or is it?

BAN SUVS · 05-20-2011, 12:59 AM

So, we can run Hydra and be OBDII compliant now? If so, what Subarus can we do that with?

Sorry I made a mistake it is doable but it can be very expensive. Basically there are two types of 2.5 Hydras for the STI, those with Gen 1 DBW boards, and those with Gen 2 DBW boards. If you have a Gen 1 DBW board honestly I think you're basically getting all new guts because those boards cannot be fitted with the Gen 3 DBW boards so it's about 50% the cost of a new Hydra for the upgrade.

Let me state that modifying your OEM ecu in any way shape or form, from flashing to replacing with a Hydra EMS, is not OBD2 compliant.

We can make your OBD2 port function and connect to your OEM ecu so you can do what you like with it, that's all I'm saying. We can sell you a parallel harness that keeps your OEM ecu in the loop and therefore your OBD2 port functioning. People have passed emissions test this way after flashing the OEM ECU but for the record Element Tuning and Hydra EMS are telling you that modifying your ecu is not emissions legal.

faeflora · 05-20-2011, 01:24 PM

Wow I see a quite a few new ignition trim maps. Very nice! Is there a list of all the new 2.7 features somewhere?

I'm researching to decide whether to buy a Hydra 2.6 for an 07 WRX. Will I be able to make my OBD2 report all the ready codes, and no more?

How robust is Auto tune? Can I eliminate the need for a professional to tune my car for little changes in setup. What about the initial tune?

Element Tuning · 06-27-2011, 05:39 PM

You would have to purchase a parallel harness from us to be able to have a functioning OBD2 port and the ability to flash the OEM ecu for codes, etc.

Autotune doesn't replace tuning, it can just make it faster. For the newer Hydras I have lots of great base maps so I don't ever use it since the base maps are very close. Lots of people do use it however.

I will be learning how to tune with the hydra. I don't want my car to go skynet on me. I would just like to be able to buy, say headers,when I find a good deal w/o them sitting in my garage for a year or compromising the way my car runs.

Do you do remote tuning?

Element Tuning · 06-29-2011, 02:09 PM

I think you're going to find the Hydra EMS a lot more accommodating of modifications. Typically things like that require minor adjustments to the fuel map.

You can buy a tech support package from us and I will work aggressively with you to help you get it tuned but make no bones about it you'll have to be coached to get the tuning done quickly. I can make changes but I make small changes each time so the process, while being safe, is slower than if you could supplement what I've done and or showed you.
