2nd Gen Mazdaspeed3 Extended RPM Tables

Why, Who, and How?

The basic nature of tuning revolves around the idea of intentionally making your car do things the manufacturer decided not to do. Every single car in the world has a rev limiter that the OEM doesn’t want you to go beyond. At a certain point, if you want to go faster and make more power, you need more RPM. The numerous factory tables that are modeled around a specific RPM range not only don’t exist beyond a specific value, they also need to be scaled accurately once extended.

We are extremely proud to announce that we have solved both problems on the second generation Mazdaspeed3/MPS! A long list of tables have now been extended within the Accesstuner Pro HL to go all the way to 10k RPM!

Who does this benefit?

Naturally, the folks with heavily built engines and big turbos that are already pushing the limits of the car will be the most excited for this update, but you don’t have to drive a monster build to reap the rewards. Not everyone needs to or even should try and rev the engine up to the 10k range but even modest builds with stock location turbo upgrades and mild headwork will gain significant top-end performance with the ability to tune these tables beyond 7000 RPM.

Accesstuner Pro HL Revision: 3.1.0+16781.18152

There are a few important details displayed above that exist in all of the updated tables (listed below) and are worth pointing out.

We did not simply re-scale the existing columns within the OEM tables. You will notice that everything in the cells from 0-7000 RPM is unchanged. By making all-new custom tables that add in additional columns on the end of the table versus simply “stretching” the range of the stock table axis, we are able to maintain the same resolution as before. Meaning that the car behaves exactly the same below 7k while gaining all the benefits found from tuning beyond that RPM. Plus, it also means that if you already have a custom tune, your ProTuner does not have to start over from scratch to make use of the extended range. The exact same tune you currently use can quickly be duplicated and only the additional cells beyond 7k will need to be tuned. Which saves your tuner time and saves you money!
