The vehicle’s ECU stores rev range information (engine control unit). Engine ignitions that reach or beyond the vehicle’s limiter can be captured and stored by the ECU. On a 6 …

Your vehicle’s data: Range 1
In ranges 4, 5, and 6, automobiles with 0% overrevs typically work nicely. Typically, hitting the rpm limits results in Range 1 over revs. Ranges two and above are mechanical over revs but remain within the engine’s internal safety limits. Ranges 4-6 are major and could one day be devastating. A Range 4 or higher vehicle will not be CPO’d by Porsche.
Remember that each rev lasts 0.00833 seconds at the rev limiter (7200 RPM), so that your 13,991 Range 1 revs at the limiter took 116 seconds to complete, 63 Range 2 revs took 0.5 seconds, and 21 Range 3 revs took 0.2 seconds.

Last summer, I bought a 2008 Boxster S. At this time, 85000 miles. I recently bought a Durametric scanner, and this is the over rev report:
How does this measure up on the abuse vs. mechanical empathy scale intrigues me. What do other people notice when they look at their over rev reports? Does anyone have knowledge about the statistics in this report? Does it run well, or should I be concerned?
What are Porsche over revs?
What it says it is, an over rev, is just that. It exceeds the maximum number of engine rotations per minute that the engine manufacturer has judged safe by one or more. They commonly happen on downshifts in vehicles with manual gearboxes when the road speed and the gear tooth ratio are out of phase.
Are there rev limiters on Porsches?
Engine rev limiters for Porsche Early Porsche 911s featured mechanical sliding ignition rotors with engine rev limiter devices whose primary purpose was to cut power in the case of an engine RPM over-rev.
Can the Porsche’s soft limiter be disabled?
It is physically impossible to remove this electronic command module, which restricts the amount of RPM in order to protect your engine from damage.
What occurs if you rev your engine too high?
By allowing a valve to remain open for an excessive amount of time, over-revving can harm your valve train and result in valve float. When a valve is stuck halfway between open and closed, it experiences valve float. There will be a sudden loss of electricity as a result.
What RPM is too high?
The redline for an engine can be anywhere from 100 and 12,000 RPM, depending on the manufacturer. When an engine overrevs, also known as “over-revving,” a valve may stay open longer than usual, which can harm the piston and valvetrain. Valve float may cause a loss of compression, a misfire, or a collision between a valve and a piston. A connecting rod could potentially be thrown by the engine between the crankshaft and piston. The engine will thereafter require maintenance or replacement.
What location is the rev limiter?
The factory-installed rpm limiter is set at the maximum revs the engine’s manufacturer is comfortable with. Despite occasionally being placed at the same location in the rev range as the redline, it shouldn’t be mistaken with that setting.
Is hitting the rpm limiter okay?
The rev limiter prevents damage to the engine. The computer prevents the distributer from sending spark to the spark plugs on some pistons when you reach the rpm level when the rev limiter engages. This prevents the engine from revving higher and damaging internal components. In order to prevent one piston from being overloaded with raw fuel, the computer varies which pistons do not receive spark throughout each rotation. While continually bouncing the automobile off the rev limits is not a good idea either, the rev limiter does not harm your engine. Before shifting, hitting the rev limiter slows down your run and wastes fuel.
Should I take the rev limiter off?
It is strongly advised to physically remove the RPM limiter to reduce any potential danger of harm to your car. Consequently, there is a particular method for electronically disabling it. To achieve this, switch out the factory default ECU for a high-performance ECU in order to go beyond the RPM restrictions set forth originally.
On the other hand, it is advised to use an automobile expert’s services if you want to remove the Rev Limiter in a secure and safe manner. We encourage you to contact Buy Tuning Files because of this.
Do excessive rpm harm engines?
You put your car and its engine under extra, needless stress when you rev your engine. When it’s cold outside, it’s crucial to do this because revving your engine before it’s warmed up can be extremely harmful because your car’s oil hasn’t had time to circulate and properly lubricate it.
PDK transmissions don’t have a clutch pedal, do they?
With the PDK, there is an electronically controlled valve body that actuates the appropriate clutch as needed instead of the usual clutch pedals seen on the floor of a car. Only one clutch is engaged at a time, smoothly switching between the two. The gear adjustments won’t even be noticed by the drivers
What occurs when an engine reaches its redline?
Redlining your car frequently can seriously harm your tires as well as your engine. It can be relatively simple to redline (accidentally or on purpose) while using manual gearboxes or shift modes, which eventually leads to your engine wearing out too soon.
Is PDK preferable to manual?
For the fastest lap times on Los Angeles track days, the Porsche PDK offers quicker acceleration and immediate reaction as compared to manual transmissions. Although the PDK transmission was first designed for racing, it also has a lot of other benefits.
Is PDK trustworthy?
Compared to other dual-clutch gearboxes, the PDK transmission is relatively dependable, but its service life is mostly dependent on regular maintenance and adherence to the manufacturer’s operating guidelines.
Why 7000 rpm is the upper limit?
Diesel and gasoline engines are built differently, hence petrol has a greater redline RPM than diesel. Diesel engines peak at about 4500 RPM, whereas gasoline engines often reach their redline at 7000–8000 RPM. This is so because diesel engines were never intended to operate at high RPMs. They burn more slowly than gasoline and are primarily concerned with increasing torque rather than RPM. Diesel engines are slower than gasoline engines because they must ignite with pressure alone and do not employ spark plugs. As a result, diesel engines run at low overall RPMs and have lower engine redline RPMs.
What exactly does DME mean?
A healthcare professional may order equipment and supplies for frequent or long-term use. Wheelchairs, crutches, oxygen equipment, and blood test strips for diabetics are examples of DME that may be covered.
Consider pricing and plan options based on your income. To quickly determine whether DME supplies are covered, if at all, look at a plan’s Summary of Benefits. When you click “Details” for a plan, a link to the Summary of Benefits will appear.
