ECU Calibration, Hypnotic

So you're finally able to buy that car you've been researching and wanting for a long time. I knew I wanted the Mazdaspeed3 since early 2010 but I wasn't able to purchase it until 2012. So now you've got that car, and the mod itch begins!

Let me guess, you started with the obvious inexpensive and easy to install mods; air intake. Then you wanted your car to sing, so you went ahead and got yourself an exhaust so everyone can hear the music of your people. In the Mazdaspeed world, it's well known that you'll need an inevitable upgrade; the HPFP internals. Some noobs (myself included) argue that they've been running a full flow modification without them, and their engines still have the rods on the inside. But believe me, it has been proven via research, data, and endless discussions it is indeed necessary to provide the fuel needed.

Ok, you've dropped a couple of grand, car sounds sexy, you can hear the turbo spoolin' and your butt dyno is telling you about all the gains. You lined up next to your buddy in Mexico and he somehow leaves you behind and pulls you like a freight-train. Where did you go wrong?

You can throw thousands of dollars of parts under your hood and potentially make less power than what you started with. Calibrating (Tuning) your car's ECU is vital in making your car use the parts you just threw in it. Tuning is a process of optimizing the function of the hardware through manipulation of the values the ECU is programmed to use and to respond to. In most cases, a car that retains stock hardware can be improved upon through proper tuning. Out of the box, any car manufacturer is on the hook for a warranty, and of course if the car wears a manufacturer’s badge, the overall perception of reliability is a long term concern. Each manufacturer has to make sure that an ECU calibration will provide safe operation regardless of geography, and variables that force an OEM calibration to be excessively conservative. Tuning manipulates the values used by the ECU software to be optimized for particular geographic conditions, those new snazzy aftermarket parts you’ve installed, as well as striking a balance between reliability and performance.

Back in 2013 I reached out to Rob Finkle, one of the most popular and well-known guys in the Mazda community, to tune my car. If you keep up with our YouTube channel, you’ll notice all of the AutoX events we participate in, as well as the occasional drag race. I knew I wanted a solid, fast car without breaking the bank, all the while maintaining the safety of my engine and keeping the rods nice and warm inside the block. Rob was the man to contact, and he delivered!

Rob has developed two solid maps for my car, one for street use that uses methanol injection and another that utilizes 93 octane gas for AutoX. The graph below shows you the difference between three different data-logs; Cobb OTS (Off the shelf map), 93 octane and 93+methnoal injection. officially launched and orders can be made directly from the website. And to make it even better, Rob has generously given us a 25% discount for three lucky Speed owners. All you need to is mention GE3KSPD!
