Sorry I don't know we buy them from Hydra EMS and they don't have part numbers still there.

We've already past the ETA.

Don't hold your breath until I get a beta.

What's the unofficial 2.7 feature list relative to 2.6?

Also, has anyone tried AEM's IAT sensor? I'd like to think it would be fast. While I understand that usage of the OEM IAT in the MAF sensor assembly works fine with the Element maps as they're calibrated for it, I'm too much of a perfectionist to leave well-enough alone. I really would like to get a nice fast IAT sensor that works with the 2.6+ units installed in my FMIC return piping.

If you're a perfectionist leave well enough alone . Let me explain.

When tuning with the Hydra using injector pulse width you are mapping your fuel curve based on boost and RPM for a given setup. As the efficiency of your setup (turbocharger/intercooler) starts to diminish your injector pulse width will not increase proportionally as boost increases. In essence the injector pulse width map is compensating for you change in VE (higher turbocharger outlet air temps). All the IAT does is apply a correction for ambient temperatures so that when it's hotter and oxygen content is less you reduce fuel and when it's cold you increase fuel.

Now you say I get it but why not measure it after the intercooler anyway? Because on a turbocharged engine for every +1 degree in intake temperature you don't get a +1 degree change in intercooler outlet temperature. Also we have found heat soak at the sensor to be a major problem often resulting in a temperature reading that is wrong and slow to react which is the opposite of what you're trying to achieve.

2.7 what's 2.7? The unoffical benefit list is huge but at this point it might as well be vapor wear until I receive a beta. I'll tease with a few options:

Dual DBW Throttle control
Quad closed loop cam control
DBW Cruise control (cable cruise control has always worked)
Si Drive functionality on the newer cars
OBD2 on board diagnostics and therefore emmissions compliance
Gauge kits
On board data logging
User upgradeable flash
New tuning strategies based on what I and other dealers wanted

Just realize you won't get all of that and more for the same amount of money. We'll offer similarly equiped Hydras at similar prices and for all the bells and whistles a higher price. The nice this is that every Hydra will be scaleable so let's say you don't need the OBD2 compatibility option so we won't charge you for it but should you want it in two years you can pay for the upgrade, etc.

This way we can keep affortable options for people who don't need everything. For many people the standard on board data logging will be enough but for racers like me I will be able to pay for a memory upgrade for hours of data logging ability.

Still no release date yet other than this year sometime.

Thanks,
Phil Grabow

I know that the OBDII function is surely going to open doors for the new car owners or fair weathered cars that haven't met that 25+ year mark to not be emissions compliant or maybe thats a Texas thing

Yeah I think moving on into the future of stand-alone engine management it's going to be an option that pushes the Hydra up a notch for the average enthusiast. There have always been work arounds for the creative but now that won't be required.

Also the OEM CAN bus support is also another feature that will advance the system allowing 100% functionality of OEM systems.

The more options the better. I will be glad to hear when the new update posts! I emailed you already today about becoming a Hydra owner

Is the CAN Bus on all the units or is this going to be a modification in the future?

Also is this what connectes to the Digital Dashes that are availble?

The CAN chips have been on many of the newer units but I don't know that every model will be equipped in an effort to reduce costs for certain applications in the future.

Currently the AIM Sports dash is via the serial cable.

I'm running a Hydra in a 04 WRX with a STi long block and am attempting to hookup the avcs.

I already have the wiring diagram to do it but I can't find any place that sells the correct terminal connectors that go into the hydra's wiring harness.

Anybody know what they are called?

I went to radio shack and they said they don't sell anything like that.
They are flat on the side that plugs into the ems.

How has anybody else done this? Just tape the wire in there or something?
I'd like to do it the best possible way.

Thanks.

You may need to rob them from an AVCS engine wiring harness.

Ok well I was talking about the terminal's that plug into the hydra's location, but yea I'm trying to figure out what to do for that end as well but I don't think it will be as hard.
I wonder if I could order the plug from the sti's harness that plugs into the avcs solenoid from somewhere?

Thanks though.

They're GM ECU/ECM pins. Call your local NAPA stores and bring one with you to size it against their stock. I found them available after the 3rd NAPA store...

That is it!
Thanks VERY MUCH!!

Here is a link to order online if your Napa Store doesn't have them. None of my napa's had them in stock and I would have to buy 25 at a time at $1.07 each. http://www.clipsandfasteners.com/GM_...e_p/a14883.htm

Thanks for screwing me out of almost $2000 for your ****ty ass Hydra, and not even giving me the correct product, and then not fixing your errors!


Edit: Keeping RS25 updated step by step as I attempt to deal with Phil at Element Tuning, if you care to follow, heres a link:
http://www.rs25.com/forums/f121/t136...-no-no-no.html
Wow, I've been working directly with Jorge at P&L to figure out your problem which by the way only took two emails and then I contact you after dealing with them and asked you to give time so I could look through my emails to see what had happened (on my end). I am human and can make mistakes but let's face it I sell thousands of Hydras and there was no way for me to remember your situation without looking it up.

I didn't respond to your emails immediately (I day after you sent it) since I was already working with your shop and I was helping a team get ready to race this past weekend which consumed all my time.

Now onto the problem you claim we're at fault for. We often add two additional wires to the harnesses used on RS models etc when they want to upgrade to direct fire coils. We do this all the time and it's nothing new to me. Now I seem to remember asking if your car was running on these coils with the OEM ecu and if it was then we supplied you with the correct harness. This would mean someone had wired the direct fire coils to fire bank to bank like the OEM.

Jorge at P&L has confirmed the OEM ecu fires the coil so this is where the confusion is. Typically when a customer wants to run direct fire when direct fire is not OEM then we add two wires into the harness so the customer can add the two addition coil wires and run those to the Hydra (since OEM has only two). To run direct fire coils properly the customer is responsible for wiring not Hydra EMS, they just provide two flying leads in the harness.

Honestly I was going to work with you a little to smooth things over even though I'm not convinced this is the actual problem. You haven't given me even a business day to check things out before going on a smear campaign as I asked and therefore I'm not compelled do anything but offer to add those two wires for you in your harness now.

Rule: Let customers know you're working on a problem. "Working on it with Jorge @ P&L" isn't hard to send.

Rule: Let customers know your schedule.

Rule: Never expect your build to fit a timeframe. Ever. You and you alone will screw yourself if you do this.

Rule: Unbox and examine everything ordered, weeks before you intend to install.

Correction: Phil is not a "shady all-for-self business man". You may be rightfully pissed about your situation, but that statement is completely inaccurate.

2 cents deposited as usual

Ok so I've moved forward a little with P&L and it looks like I didn't make a mistake and the correct wiring harness was sent. Off the top of my head I thought the 95 JDM car was a dual coil setup but it's actually individual so the harness would be totally plug and play in this situation.

I've given Paul at P&L the correct wiring diagram and he's going to check the coil pins to see if Hydra EMS made a mistake with the wiring.
