Why Every Mazdaspeed Owner Needs the Cobb Accessport


What is an accessport?

The Cobb Tuning Accessport is a device that communicates with your ECU (Engine Control Unit). When you own an accessport you will be able to read error codes, modify engine settings, and take informational logs of data to keep your Mazda running reliably, and to give it more power.

The main reason people purchase the accessport is to install maps on their car.

What is a map?

A map is a preconfigured group of settings or parameters for your car. Want your Mazdaspeed to get better gas mileage? Run the “Economy Mode Map.” Want your Mazdaspeed to run faster? Remove the boost limits in 1st and 2nd gear, then run a “Stage 1 Map.”

Maps also allow you to tell your ECU specifically what power modifications you have done and how you want them running. If you have a new downpipe that flows better and Max Flow Fuel Pump Internals, then your ECU will need a new map installed that tells it how to control the boost levels by controlling the waste gate, the spark advance, ideal fuel pressure, fuel trims, and many other things.


So where do I get these maps?

The Cobb Accessport will come pre-installed with a few maps that are known as OTS (Off-The-Shelf) Maps. They are basic maps that should cover a wide variety of parts. Though they are more beneficial than keeping a stock ECU tune, they are nowhere near as beneficial as doing a custom tune. Custom tunes can be done by anyone with Accesstuner Pro who is willing to devote time to learning the ins and outs of engine control management. Most people who don’t want to spend hours tweaking small variables to meet safe and powerful conditions choose to get a tune done by a professional.

For the Mazdaspeed platform there are many tuners to choose from:

How do I use this thing?

The accessport is really rather simple. If you can use a modern smartphone, you can figure out the accessport.

  • Step 1: Find the OBD II port on your Mazdaspeed 3 (located on the left side of the dash above the hood lever, below the traction control switches.) and then plug the accessport cable in.
  • Step 2: Tell it to install. Make sure you follow all directions on the screen and don’t shut your car off halfway through install.

Once installed to your car the accessport will not be able to be installed in any other vehicle unless you uninstall it. This is called by many “marrying “ the accessport. You can only install an “unmarried” accessport to your car. If it’s already “married” it will not work, which is why buying one used can be so sketchy.

Now that it’s installed, you can change maps, do datalogs, and view check engine lights right from inside your car. When it isn’t installed, you can easily connect it to your computer and load the accessport manager to copy new maps to the device, or open datalogs in Excel. You can eve use tools such as Virtual Dyno to monitor performance gains.

Once you have installed the accessport and decided on the map to use there is only one thing left to do: Drive. Get out there and enjoy your car with its new power curve, removed boost limits, and better breathing. If you thought your car was fun before, just wait until you get an OTS map installed with your accessport and put the pedal down for the first time!

Once you’ve done that and realize how amazing it is, I dare you to get a custom tune for your specific car, modifications, gas, elevation, and driving habits. You will be BLOWN away.

Overall, the accessport is an amazing device that every Mazdaspeed owner should have for safety, reliability, power, and to learn more about your car. Let us know if you have any questions about them, or purchase one here.

New Product – Power Series 3″ Intake for Mazdaspeed 3

CorkSport introduces an all new Power Series 3″ Intake System for the 2007 – 2013 Mazdaspeed 3


With much demand for wanting more air and a throaty roar from your Mazdaspeed engine, Corksport is proud to bring you our Power Series true 3″ Intake System.

Mazdaspeed MAF

We have so many people ask for bigger intakes and MAFs that we set out to make a better one. Traditionally most MAFs are constructed from a welded pipe with various fittings for the MAF sensor to sit on or they are machined tubes with various fittings welded or bolted on.

What are the limitations to the current way of doing things? Most companies call a 76mm (3”) MAF, 3” because the outside diameter (OD) is 3” or 76mm. That really doesn’t tell you the amount of air the intake can flow. It tells you that you are using 3” connectors but the  inner diameter (ID) could be anything.

For reference the stock MAF is 68mm ID. Once you are in the low 300whp range your MAF sensor will read 5volts. This means that your MAF is “topped out” and does not have the ability to adjust fuel trims and timing properly. To get the head room of tuning you must upgrade to a larger MAF diameter.

The Power Series 3″ Intake System is fabricated with a high polished 3 inch turbo inlet pipe and a true 3″ inside diameter MAF housing. The velocity stack design smooths air flow for maximum performance.

In order to increase the ability for a large MAF to flow as much as possible and still not top out we decided we wanted to “bell” the MAF entrance. This effectively increases the air velocity, flowing more air. This is almost a 10% increase in velocity over the non “bell” version of the same MAF. This is something that is not done on a welded MAF. You can also make the MAF any size you want so making a true 76mm MAF is possible. This added head room allows your mods to go further and gives you the ability to tune for more power.

To help with proper idle and cruise resolution we also added a splitter to straighten the air in front of the MAF giving a better signal to the ECU.

If you plan on upgrading or have already upgraded your turbo this upgrade is a must to keep your MAF sensor functioning within its calibrated range.

PART 1 – (Go to Part 1)

“… Most aftermarket fuel pump upgrades consist of changing the internal parts of the factory pump with an enlarged piston and sleeve. By enlarging the piston, you increase the volume of the pump; thus creating more flow and the ability to maintain pressure at higher power levels.

When you first start taking the fuel pump apart, the first thing you are met with is the sight of a strange black deposit in the cap of the pump. Shown above are the deposits common to most caps. The bottom is a machined surface that should be clear of debris. In order for us to more clearly understand the situation we sent the cap out to undergo chemical analysis.”

“Does size matter? When looking at the stock piston on the factory fuel pump you can sure say that it does matter. If you increase the piston diameter you increase the flow of the pump. We have decided to compare the similar internals first and then compare the APR pump afterwards.”

Part 3 – (Go to Part 3)

“Now that we have a good understanding of the basics for these high pressure fuel pumps we can start to really dig deeper into the specifications. One of the items we were really curious about were the materials used in the construction of these pumps. We decided to have the hardness tested and ascertain the materials used. The factory pump internals do not use any coating, the hardness test showed us that the internals went through a hardening process as the core was significantly softer than the surface. Because of these hardness requirements, many other aftermarket internals use a coating of some sort to decrease friction between the piston and the sleeve. As for what the stock internals are made from, we answered that. Except for the hardening procedure, according to their chemical breakdown, they match a common die steel, so nothing too fancy.”

“ … We then built all the internals available in SolidWorks and tested the efficiency of them all for flow design and volume. This was merely the beginning of our design phase but helped us realize many great ideas (as well as a few not so great ones). We ended up with a design unlike any other on the market that, according to the data, would be more efficient than anything on the market.”

“After choosing a very strong alloy for our internals, we then machine their tolerances to an incredible 6 microns! To make sure the tolerances are paired for life, we serialize the parts to prevent any issues and to track the life of the pumps. We then surface treat the pumps to achieve the alloys maximum strength; only after the maximum hardness is achieved do we apply our surface treatments to bring the overall durability to an even higher level”
