Yea, that's the shop I was thinking of.

You've tuned on my car a couple of times. The most recent was a couple years ago at a shop here in Indianapolis. I believe you were coming out to get your new trailer, if I remember right. They had a sketchy setup, and my car basically came off of the dyno. After that, I pretty much tore everything apart, and am just now getting it all back together... I have way too many hobbies.

i need someone to rundown PWMmap 4 for boost control on a 2.6 unit.

start boost:
percentages:
and set value:

i dont quite get it. i get that start boost is 100% duty cycly until 100% target boost is reached so is set value under the (100% cell) the duty cycle need to maintain 100% boost target.??

thanks Gabe

Well you have your start RPM for when you want the Hydra to start opening the solenoid.

You have your PID functions which are used to stabilize and determines the overall effort the ECU applies to hitting the "boost target".

The main maps are PWM Map 4 and the upper learn limit. The upper limit is the highest duty % you'll allow for a given RPM. PWM Map 4 is 0% effor to 100% to hit the boost target. So if the Hydra is trying it's hardest to hit the boost target the value in the 100% load cell is the duty% the solenoid runs at. If it's not trying to increase boost, 0% effort is used and that value is what is duty% is used.

For ease of use just make PWM Map 4 a straight line, say 30% and see what boost you hit. Raise or lower that to hit your peak target. You can then slope the line so that the Hydra can raise or lower the boost if required due to gear or air temp.

^^ Thanks.

If i decide to use a stand alone boost controller IE: Turbosmart EBOOST2, all i would need to do is set the targets and max boost fuel cuts, do i need to disable the hydras boost control system in any way?

you should have to just your max boost fuel cut for saftey but once the stock ebc is diconnected those maps and settings wont matter. no need to 0 them out or anything.

ATS and CTS Type settings??? What should they be.

going through the check list of sensors and it says that the AT and CT should be close in value when you flip the key on and engine has not been running for 24hrs or so. makes sense it should be around ambient but the CT is 65degrees F and the AT is 81degrees F. the ambient Temp is more like 65degrees so the AT is way off.

Sounds like you're looking at "Port Air Temp" which uses a calculation to estimate the temperature from the IAT sensor to the actual port. This factors the time it takes from the IAT sensor to the intake port where it's heated along the way. When you RPM picks up the IAT and the PAT come together since the time from IAT to Port is almost instant and therefore no heating.

ok so there is no issue then, the ATS type is "ATS Delco" and the CTS type is "CTS Delco". those are the correct settings?

Seeing as the 2.7 manual is still missing in action, and I can't get an answer from Hydra, does anyone know on the 2.7 what pin is aux4? I can't find a wiring diagram for the 2.7 anywhere. I'm trying to setup my external wideband input, which I paid to have unlocked an I'm not sure it actually is, and I need to make sure I have it wired into the right pin. Right now I have it in BC11 but I can't get a confirmation if that is aux4 or not.

The 2.7 manual is not 100% yet but will be incorporated directly into the "help" menu soon. The current manual is here online:

http://www.hydraems.com/nemesis27page/1/manual/

Element Tuning Hydra EMS 2.7 External WB Sensor Instructions

Go to "Help/Activate/Sensor Calibration Maps" and give us the Mac id to unlock sensor calibrations map. When you receive the "Key" you may enter this to unlock this feature.

Under Settings/Input Request Types use AUX 2 pn BB4. ( or any available 1-4 (4 is BC11). Set up as "Left External Wideband."

Go to Tuning Maps/Target AFR Table/Setting. Primary Lambda set to "Left External Wideband." Left Module Sensor Source set to "Left External Wideband Sensor AFR Target Table."

You must enter your WB's calibration values under Tuning Maps/Sensor Calibrations/Auxilliary Input 2 External Sensor. Put in your WB manufacturer's 0-5 volt AFR curve.

When you are read to do more than log "Left External WB" then check the box after tuning to "Enable Colsed Loop Fuel Control, Left Module."

I figured I was still missing something. It took me a while for them to get me the correct harness for my SVX and everything in the first place. I sent my Hydra dealer a message over the weekend and he said he will get in touch with Hydra, but I'm not really confident he will get back to me, as he is already a day after when he said he would call me. On my receipt I have a $175 charge for "External Wideband and Calibration Unlock
for Nemesis 2.7" so I know it is a feature I should have. If I can't get the key from him in the next couple of days maybe you would be able to help me out with it if I give you the MAC address.

It is good to know that BC11 is aux 4 input so I don't have to take it back out and rewire it to a different pin. I've already figured out all the settings to use the wideband, except obviously I was unable to get to the advanced sensor calibrations map to get it running.

Thanks for helping us all out with Hydra, and I would've gotten mine through you, but I knew for a fact that the person I went through has dealt with the SVX and the harnesses for it already and had the correct contact at Hydra to deal with the SVX.

I'm sure we sell more SVX based Hydras than anyone but they are mostly custom setups so we don't list it a point and purchase on our website.

I can provide some basic support here but because you didn't purchase from Element Tuning or one of our dealers you'll have to relay on the dealer you purchased your unit from. I would CC Hydra on the email requesting the unlock code and don't forget to also send the Hydra serial number.

An update for anyone curious. The Hydra 2.7 WILL NOT run Long term trim/autotune off of an external wideband O2 sensor even if you have the inputs unlocked and the wideband O2 running properly into the Hydra. They have it setup to ONLY run the Long term trim/autotune on their own wideband setup.

This is a little disappointing to me as I am running a Zeitronix for my wideband, EGT, boost and oil pressure, and have the wideband output to the Hydra properly (and paid to use this feature with the Hydra) and now I can't use the Long term trim/autotune feature without spending more money on the wideband from Hydra. Not to mention having to pull the ECU back out, wire in the Hydra wideband, run the wires out with all the others, and then try and find somewhere to fit a 4th O2 sensor in my exhaust (which is already coated, wrapped and in the car), when I already have a properly functioning wideband setup.

I'm not a professional tuner, and was hoping to get the fueling map close and let the Long term trim/autotune clean it up some until I can find someone that I want to tune it dead on. This would also allow it to be driven to my alignment shop and to a tuner.

I've been very happy with the Hydra and still am aside from being mislead into believing that this would work with an external wideband as long as I paid for having the feature unlocked. There is nowhere that mentions that you are REQUIRED to use their internal wideband for the Long term trim/autotune. So just as a word of warning or advice to those looking to get a Hydra, get their wideband setup with it instead of getting an external one if you don't already have an external wideband and don't need something to combine gauges.

My choice to go with the Zeitronix for my gauges is due to the very limited interior space for gauges in an SVX. I didn't have the room to run separate EGT, Boost, Oil pressure and wideband O2 gauges and was happy to use the multi-display LCD to fit everything into one small location.

Yeah your dealer let you down on that one, the external wb is only for logging and closed loop fuel, not Autotune.

I tested the latest autotune I tested our HYDRA FRS/BRZ project and I was impressed with well it worked. I think for most experienced or those very proficient with the Hydra the autotune won't be used much if provided with a base map from Element Tuning. For new tuners or say building a map from scratch it can be very useful.

I have an 05 sti with a hydra 2.5. I am trying to figure out whether my harness has the accessory harness on it. How can you tell? And if it doesn't can I still buy one?

Post a picture but if you don't have it you can buy it from us. The additional harness would have a 6 plug wiring loom attached with an additiknal relay, wires, and a grounding eyelet.

FYI,

My car is being used to finalize the 2.7 software upgrade for the Hydra EMS. It should be finished this week. I will update when I get the car back.

Specifically the CAN Bus stuff so we have the option to run 100% stand-alone on the 08-2012 STis like we can with the 2013 BRZ/FRS. Thanks for your help!

You are correct, sir. I should have the car back on the 16th with the 2.7 installed, running the car.

Update to 2.7 R&D:

I just got off the phone with Andy and his engineers have encountered a couple more issues after addressing the ABS problem. I was supposed to have the car back tomorrow, but I told Andy to keep it until Monday the 21st, giving them some time to examine the software problems and hopefully correct them.

I will continue to update. Thanks.

I don't think most understand what we are using brewski79's 2011 STi to R&D. For the 2008+ STi and WRX models we run the Hydra EMS in "parallel" so that the dash functions due to a heavy use of CAN on these cars. CAN systems are not universal so each application requires reverse engineering of the CAN system so the CAN chip in the Hydra EMS can be developed and therefore relay all the data needed so the CAN computer in our cars can function 100%.

The 2013 BRZ/FRS has an extremely in depth CAN system and were able to fully develop a 100% plug and play standalone for that car and still have 100% dash function, ABS, electronic steering, AC, etc. I'm still knee deep in R&D for that car which is why we haven't pushed to market it just yet.

We now want to offer a 100% standalone for the 08-2012 STi with a developed CAN system so nothing is lost in the transition to standalone.

By the way thanks again for your help!

Good news: The 2.7 software development is finished. I got the phone call from Andrew today around 12:30pm stating the engineers had fixed the last of the bugs/issues and that I could pick the car up. I don't have the 2.7 in my car for the time being as Andrew wanted to finish the wiring harness. I don't have a timeline of when the 2.7 will be ready for release to market. Maybe Phil can chime in on this.

Also, I will continue to update if I come across any more information.

Thanks,
Chris
