In effort to consolidate my gauge situation I picked up the AEM Wideband Failsafe setup. This not only will display both my boost and AFR on the same gauge face, it can be setup to activate trigger outputs when my fuel ratios step out of line.
Just like the methanol failsafe gauge I installed – It will log internally allowing me to connect my laptop to view the logged data. It will log RPM, BOOST and AFR.
The idea is to have your car tuned and functioning as usual – data log this normal activity and create thresholds. If for whatever reason my car steps outside of these parameters I will be notified and the gauge can trigger something externally to make sure everything is safe. Example: Wastegate solenoid, secondary fuel map, secondary ignition map or even a simple LED on my dash to notify me there has been a problem.
As usual with AEM, the gauge is complete with everything you need. Nice looking setup.
I wanted to keep things clean so I removed my previous UEGO gauge and my digital boost gauge. The previous routing was clean so I’ll stick with the defrost vent.
The wire coloring was the same so I basically snipped the previous harness and resoldered my connections.
The gauge has a full color display in the middle and the led band around the outside. This is all configurable in the software.
Overall a great looking piece and certainly will help. It’s not like I could ever keep my eye on the UEGO gauge while ripping through gears so the Failsafe gauge really makes more sense.
