I too am running the aem failsafe. With the AVO turbo kit. I am running the Grimspeed EBCS for boost control (factory fit and plug/play). I have it wired similar to the diagram. Basically, on the EBCS it is plug/play to subaru. The wires are simply 12+ and ground. All you do is run that blue wire to one side of the relay (86), 12+ to the other (85). Then cut one of the wires on the EBCS, doesn't matter which one. With the cut wire, run one side to 30, and the other to 87a. This allows it to function just as though there was no relay. Then, when the failsafe has an "alarm" it will trigger the relay, which opens the relay circuit (30 now connects to 87, which is empty), this essentially cuts power to the EBCS and you are now at standard wastegate pressure.
I will draw up a schematic when i get a chance. I have yet to actually setup my AFR alarm, as i am waiting for my tuner to get the EBCS tuned with my new Clutch, so i have it all wired and working properly, but right now running a MBC until i have the EBCS setup. This will be happening in a couple weeks (hopefully). Last edited by gdrider77; 08-26-2013 at 01:44 PM. |

So, the boost level of the Grimspeed EBC is run by EcuTek via tune? Is this a popular EBC to use for EcuTek tuning?

I run a COBB but it's all the same.

Where are you guys grabbing the rpm signal from for the gauge?

i use both boost-based and afr-based failsafes in my tunes when possible. in order to use the afr-based one you need to have a wideband wired into the ecu. it's very simple, just a custom map that calculates afr error and another to respond to it however you like (cut spark, fuel, boost or close the throttle usually). it works in concert with my full-time closed loop fueling strategy, which i often end up removing after the fueling has been dialed in (it uses up a lot of custom maps).

Yeah, pretty much any EBCS will work with the diagram i posted. They are all the same essentially.
With the new option of the wideband feed into the ecu via obd2 signal you could really just eliminate this type of connection, since you can do as @jamesm mentioned and have the ecu detect the true afr and switch to a custom map with fuel cuts, boost cut, etc... I am having mine tuned currently for some options like this, since i already have the failsafe wired up, will probably just keep it in line as it wont hurt anything, adds a bit of redundancy. But have the wideband wired into the ecu now for true logging of that as well. RPM signal is under the pass side in a harness. here is a thread about it. http://www.ft86club.com/forums/showt...ailsafe&page=4 |

Is it possible to have a flex setup using the rear o2 sensor, a wideband feeding into the Ecu via the CPC input and an EBCS running from the CPC output all being controlled via Ecutek?
Where do you grab the CPC inputs/outputs? I understand the CPC output is under the inlet manifold. Just trying to get my head around this stuff. |

My tuner is telling me that running the UEGO wideband from my AEM failsafe to the ECU is just an over complication of things. That Ecutek already has enough safety features when tuned correctly. Am I just being overly paranoid?

Going to be putting mine in soon as well. No failsafe since I don't have an EBCS now. Basically it should just be a matter of installing the wideband and connecting some power wires then correct?

At a minimum yes it is a matter of running the harness from the sensor itself, a boost source, and a power and ground wire.
