Sorry Bud, I wasn't insinuating that you yourself were. I've had this same discussion with other people and they are so adamant that they constantly watch all the gauges at the same time and trust their eyes and reflexes more than electronics.Kevin I never said I was constantly watching the gauges. Having the ecu warn you is a great idea. My ecu has some warning I use. Not every ecu has has that ability. I sure wouldn't rely on a stock eec CEL to warn me that my boosted engine was running lean under boost. Engine could be damaged by than.
What ever works for you.
There are extra devices that can be added and used to police the vitals. One thing I use is a Lean Protection Module with the ability to monitor two O2 sensors which kills the spark when either of the O2 sensors read leaner than what I have programed into it. This means that if at WOT an injector doesn't open, fuel pumps aren't supplying enough fuel, exhaust leak pre-O2 sensors, plugged fuel filter, or simply a tuning error causes a lean condition the ignition is shut off until I let off the gas and the TPS value drops below 1.5V or so. Once the throttle is lifted the ignition comes back on and I can drive the car normally or try another blast if I dare too.
Given such advancements in electronics why would anyone want to rely on watching a WB gauge (or any gauge) for protecting their hard earned investment during a WOT blast?
