Turkeylord Posted July 19, 2013 Share Posted July 19, 2013 http://www.aemelectronics.com/images/Wideband_Failsafe_Header.jpg I just ordered one, anyone else installed one yet? Looking for ideas on what to do with the failsafe output. Warning light? Wire it to the EBCS? Link to comment Share on other sites More sharing options...
Turkeylord Posted July 24, 2013 Author Share Posted July 24, 2013 Gauge showed up yesterday, couldn't help but power it up on my desk at work... http://i.imgur.com/gqmAnQdl.jpg http://i.imgur.com/udgnJt2l.jpg I'll try to get some pictures when I install it.

EK_YYC Posted July 25, 2013 Share Posted July 25, 2013 I have one installed in your pod Block8head. Love it! Extremely customizable as far as gauges go with various faceplates. Interchangeable readouts (inside afr, outside boost, visa versa, or both boost, both afr and a couple others is think. Software is exceptional as well. For the price, there isn't anything that really comes close to what this delivers. Install was straightforward, only issue I had was they don't provide you with long enough vacuum line to tie in correctly so you'll need to get some of that. But that is minor. I would recommend it to anyone! Don't have any pictures this second but if someone is interested I can try to get something up later.

Turkeylord Posted July 26, 2013 Author Share Posted July 26, 2013 I'm trying to resist a pod from you Block8head, they look slick as hell. Trying to be stealthy though and keep it in the cubby. Thanks EK_YYC, I picked up some vacuum line before I started and you were right on. Now for the progress. All the work under the hood is done! Thanks to Underdog for this post that helped me decide where to run everything through the firewall. I decided to pull some extra wires at the same time. Pulled a red, yellow, black and blue, wrapped in some spiral wrap I had laying around. Blue will probably be the failsafe output to the EBCS, black maybe for future remote start hood pin, and the other two are extras for now. http://i.imgur.com/UHcR9vYl.jpg Closeup of the 3 runs. http://i.imgur.com/wWYCj5Zl.jpg Modified the stock grommet by punching some holes with a piece of tubing. http://i.imgur.com/nU7ITGtl.jpg And here it is installed. http://i.imgur.com/LGI7dDWl.jpg Close-up of the tee I used for the vac line. Decided to tee it here for a clean install and shortest distance to the firewall grommet. http://i.imgur.com/qNIt8WSl.jpg And here is the wideband O2 sensor. http://i.imgur.com/AVVUyHEl.jpg So far so good.

Turkeylord Posted September 1, 2013 Author Share Posted September 1, 2013 So I was able to tap into the wastegate (aka boost) control solenoid circuit at the ECU instead of at the EBCS. *Use these instructions at your own risk, and don't forget to disconnect the battery while you monkey with the ECU* I used a standard Bosch type relay to interrupt the signal going to the EBCS. You'll find the EBCS wire at the ECU - connector B134, pin 32. Cut it at least an inch away from the connector. Relay terminals are wired: 30: EBCS wire, ECU side 87a: EBCS wire, harness side 87: Wired to 86 through 100 ohm resistor 86: 12v (from cigarette lighter) 85: Failsafe output from gauge 87 is wired to 86 through a resistor to feed the ECU 12v while the failsafe is activated. This prevents it from throwing a P0235 DTC every time you start the car or trigger the failsafe. http://i.imgur.com/GWySITPl.jpg Quick, terrible video I made showing the thing in action. You can see it cut the boost and flash red to tell you it had been activated.
