That's been discussed but I have never heard a sensible answer.

ya, was first thing i learned on these when i began my successful argument with porsche, as they feebly attempted to blame ME for 2nd gear pop out, which began an adversarial forensic look at the dme reading for type two's relative to operating hours. i maintained successfully the type twos occurred while in their possession, not mine, resulting in a $10K repair bill on pcna's dime.

it's never a bad idea to pay attention to these, relative to extant or potential issues when buying.

I guess if you rev through the 1 range in one second and stay in the 2 range for 2 seconds, then you'd have twice as many type 2 than type 1.
Does that make sense? Lol
Not very comforting though.

"02996ttx50

the whole question of how theyre calculated is confusing to me. btw yes, ***1148 i have not heard a sensible answer to this either. ( its ok to reference your number, ya? lol )

"i wondered the same thing. i also have raised 7200 redline i can only imagine how many 2's I've got. but agree, theoretically the 1's should go up as well wouldn't they? can ya have 2's without corresponding 1's is the question."

I have a raised redline. To 7100 I believe.

I only have 75 range 2 but thousands of range 1.

And I definitely red-line my car every so often.

7251 rpms trigger range 2 iirc

i believe if you go into the range 2 range 1 stops recording....meaning more time in range 2(above 7251) than range 1 (between 6751 to 7250)

Most of the DME over rev information is very suspect. My car has 7500 redline and gets there frequently which I can see when I pull my data. Highest I've recorded was 7644 recently. My DME however does not record any range 1s and shows range 2s only going up at a very slow rate. People make too much out of the rev data. Do a thorough PPI and enjoy the car. These motors are very tough...

According to the calculations from the website Dock (thanks BTW) provided this has spent .44 min above red line in its life.

What software is this. I'd like to see how many times mine has been programmed.

So bouncing off the rev limiter like a Honda would give more 2s than 1 I assume.

If you run onto a wet road or tarmac and accelerate enough to break the tires loose in 1st or 2nd gear AND you hit the Rev limiter, you "can" trip Type 2 overRevs.. I have seen customer logs over shoot the stock limit by 400 to 500 RPM's with the dual mass flywheel. The fuel cut will not slow down the inertia/ramp rate/accelearation of the crankshaft.

So are these cars to be avoided? The type 2 overrevs in this car was 1956. Has a rev limiter of 7300. New turbos, intake, intercoolers, meth but not tuned to meth, was just for intake temp. It's a beautiful car and I like the fact that it has alot of mods and power.

Let's answer it this way.. Why is the seller selling the car after recent upgrades?? Odd??

Running a 7300 RPM limiter with a dual mass flywheel can leave the door open for 7700 to 7800RPM's excusions..

Do you have monies in your wallet to rebuild this engine? Better yet, can you stomach a engine rebuild?

Lastly, Today we have datalogging tools that will tell us how the engine is running. The safety of your tune and knock retard per cylinder.. For an engine kit like this, the previous owner should be able to hand you over reams of spreadsheet data. Lambda, knock, timing and boost. If you can't obtain this data and information, I'd pass....
