Its still in place. Never took it off. Problem is when you're under full throttle, 45psi boost, and 2800-3000 rpm when the flex plate goes, it doesn't really matter where your limiter is set. Its going to spin as fast as it wants for a split second.
Nope. It'll stop it dead in it's tracks if it's programmed to pull MFD to nothing shortly past your full cut point.
I've broken two converter hubs, one OD planet, one input shaft, one driveshaft u-joint and one differential carrier. My engine has never over-revved the 3850rpm limit.
I'm simply suggesting that a tiny bit of effort toward making the limiter actually limit the engine might be a good investment considering that broken driveline isn't necessarily the exception, but more the rule at that power level and beyond.
Just seemed like you needed to know that YES, the limiter WILL stop the engine RIGHT NOW, no matter what you have going on. You stop the injectors and I ASSURE YOU, that the engine will stop accelerating immediately, barring the existence of any other injected fuel source like propane.
Just know that. If your program overruns the limiter, it's not because the PCM can't stop the engine. It's because it's not being told to.
It's not a 1970's gasser with solid lifters. It's a fully electronic engine.
