I have the AEM wideband failsafe gauge, which is designed to run one sensor. I have a 300zx twin turbo, and with a true dual exhaust setup that never meets, so how do i monitor both banks of cylinders? In the past, many 300 zx owners have simply installed two sensors and two gauges, but obviously the failsafe gauge is much more expensive than a basic AFR , and I'd rather not buy a second one. So my question is: Can the failsafe be wired to monitor two sensors simultaneously, or would it be safe to run just one? Any help or advice would be greatly appreciated. Thanks.
