Suggestion
If you're really concerned, then run a durametric and see what Range 2 overrevs is reading and then check the other vitals.
Leading evidence: 'Check other vitals' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check other vitals' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

In all my years of driving, I never hit the rev limiter ... until yesterday! Left it in first gear too long then the engine started lugging.. I'm OH ****! Changed up to second and everything seems fine. Any concerns or things I should look out for?
The rev limiter is there to keep you from over-revving the engine. It did its job. It's an electronic watchdog. If you hit it a lot, you should consider learning that point and avoiding it in the future, but it's there for a reason, to keep you away from the mechanical limits.
The rev limiter CANNOT protect you from a bad downshift (one that, for example, over-revs the engine by mechanical force to 8000RPM). These are "type 2" over-revs and can go beyond the mechanical strength of the engine components. This is when bad things happen. So be much more concerned about downshifting agressively, if you get that shift point wrong, then the electronic limiter can't help you.
I wouldn't worry about it. However, excessive over-revs can greatly harm an engine even beyond what the limiter can protect. If you're really concerned, then run a durametric and see what Range 2 overrevs is reading and then check the other vitals. But don't sweat it. I've mistakenly over-rev'd all of my sports cars from time to time. I'm not stupid though, I understand there are mechanical/performance limits to these engines and if you push them too far, you'll be in a heap of trouble.
My 99 was a track car for many years. It still has its original engine (or so it appears - a 1998 M96.01). It hit the maximum number of ingitions the ECU will count years ago. That's about 3 minutes or more at the limiter. My car runs great.
Nope - I can't believe you're getting this advice.
You've totally trashed the car. It's done.
I'll be nice and offer to buy it from you now for $5K and deal with the cleanup myself.... lol
Rev limiter is just fine! It's when you exceed the rev limiters limits by missing a down shift - that's where the money starts flowing. They don't call it a money-shift for no reason.
True. I bought a durametric to see what my range 1 and range 2 numbers looked like. The range 1 number was over 60,000 ignitions, as I recall. I posted the number in one of the treads and one of our observant and knowledgeable members pointed out to me that the number I posted was the max value the ECU would record!
I do have about 3 seconds total above range 2, but they were very early in the car's life, well over 50k miles ago. Three seconds may not seem like a lot, but some members of this forum have had engine failures in less time. What the data doesn't tell you is how many events above the range ocurred or how far above the RPM setpoint the engine went. Multiple short events 100 or 200 rpm above the setpoint probably won't do any damage. One event 1000+ rpm over the limit could damage the engine. If you are looking at buying a car and the PPI identifies range 2 over revs, what is important is how long ago they occurred. If the car has been driven 50+ hours since the last event, it's probably ok.
Edit: I found the picture I took of the durametric readout and the range 1 value was 65535, which is apparently the max.
made me laugh! I guess I�m just a cautious driver. I want to take it to the edge but I stay 6 inches away from it! And this is from a guy who jumped out of planes a 30000 feet!
I�ve never had a range 1 as long as I�ve owned the car (confirmed by my durametric). Just never seen the point of hitting the limiter. The motor has already signed off by around 6,800rpm. No more power to be had going any higher. I�ll take it to 6k rpm on just about every drive but above that, no so much.
You Tube
Its no problem to hit the rev limiter....I hit it all the time on the track....but wait....I did blow my engine on the track on long sweeping right hand turn so what the hell do I know.
Ahh That video's soundtrack was the perfect way to start my Friday!
What exhaust setup are you running? Sounds marvelous! I currently hate mine and it makes it harder for me to enjoy the car.
Yea, don't be spooked... go out and enjoy the car. Jumping at anything that moves or makes a sound will only cause you to not have fun with the car. But if you're really think you've ruined it, then take the $5,000 from Blue Chip and go buy yourself a used Camry! hahaha j/k
