Product: AEM Gauge-Type Uego (Gen 1, not the 6-in-1)
Place Purchased: Horsepowerfreaks
Price Paid: "CALL"
Application: Universal
Highlights: Analog-style gauge with a digital read-out center, accurate to within 0.1 AFR, and readily available (inexpensive) replacement bosch sensors
Caveats: The Gen 1 had the harness hard-wired into the gauge which made routing the harness through the dash and through the firewall a chore. The new 6-in-1 has a plug at the back of the gauge, so you can push the harness through the firewall from the engine bay (much easier)
Installation Difficulty (1-10, 10 being difficult): 5, See note above
Installation Tips: Do not wire the 12V power to a switched source, but instead use a relay and constant power source. The signal will be cleaner for more accurate readings. On the MK3 Supra, you can buy a ~$35 bosch O2 sensor for a NA Supra and unthread that sensor from the flange. That flange can then be bolted onto the downpipe and the wideband threaded into it (no need to weld a bung).
Rating (1-10, 10 being best): 9
Additional Comments: I originally installed it to a switched power source, but had difficulties getting the gauge and the EMS to show the same readings. After checking the aem forums, I discovered the relay trick and it solved my problems
