On a drive-by-wire engine, Gen 3 or 4, does it hurt to set the rev limiter relatively low(2k to 4k range), and then just block the throttle for all-day operation? Or is there a compromise in doing so?
Another way of asking the same question -- what does the rev limiter do? Does it effectively throttle back the engine in a normal fashion, or does it merely cut off the fuel and/or spark, and risk the engine going lean?
I'm wondering about the feasibility of using these GM v8's to power a stationary implement that requires a steady output speed. I could go the cruise control route, but the simplest might just be to bolt up a sm465 transmission, and set the rev limiter where I want it.
