Mazda Miata MX5 ND

Complete ECU Calibration package for your ND Miata. We are very happy to say that we have defined the ROM on the ND Miata and tuning is now available.  From countless hours of revising and testing, we have created a Calibration for the Skyactiv-G engine that is unmatched in terms of power, reliability, and accenting what the stock engine does best. MPG.

Tuning Various Skyactivs across the globe has brought a leading edge to ND Tuning.

We have pulled out more power, more torque and more miles per gallon out of the skyactiv 1.5L, 2.0L and 2.5L through countless hours and over a year of testing, which we have now brought to the Miata ND. We have calibrated Skyactiv engines from Japan, USA, Canada, Mexico, Malaysia, Indonesia, and everywhere in between. This has given us a glance at how Mazda has these vehicles calibrated, to specific markets, worldwide qualities of fuel, and climates. With this information we have developed a calibration that is simply unmatched.

We don't try to make these engines something they are not. We accent what they can do, and we "unlock" the power that Mazda "turned off". A quick look at the Cam phasing on these engines and you can see that Mazda actually "bumped up" the tables in a few areas (specifically where they make peak gains) to make the numbers look good. However everywhere in between is a dead zone! Rather than try to re-invent the wheel, we accent what the Skyactiv Can do.

With over 4000 tables in the latest ECM's, we tested for quite a while before tuning was released to anyone.

  • Ethanol tuning. Confirmed Results are drastic.
  • High octane tuning. Best Daily driven results on 91-94 octane


  • Cam phasing. The cams are the power maker, or power killer. We won't say what we change, or how, but we can say you must pay special attention to ALL the cam maps, to make a proper calibration. 


Fueling. The Skyactiv has a very interesting and complex way of fueling. there are several maps, for nearly any condition, that must be given special attention. The 2x D.I. Spray cannot be ignored. Why is fueling important? Because Skyactiv engines run extremely high fuel pressure, and is a very delicately balanced system.

From Fuel pump duty to injection amounts, tuning these engines require a bit more than just knowing "AFR" values. Understanding the Injection multipliers, compensations, and injection timing and phasing will be the key to creating power safety, and keeping MPG in check.


The ignition strategy on these engines is unlike most others mazdas. Almost "subaru-esque". As in they will dynamically ADD ignition timing when recording "no knock" events. Which means that the ECU will listen for knock, record no knock, adjust ignition timing, record for knock, until a knock event takes place (or Maximum allowable ignition timing has been accomplished).

Tuning for this is complex, and takes time. You simply cannot tune these engines correctly with 1 or 2 flashes if you're touching ignition timing. The dynamic control of the Ignition takes time, and a very meticulous understanding of what's going on in order to properly adjust the proper tables( over 50 of them!) to have adequate ignition timing control that won't be stopped once the ECU takes control. Simply adding timing and watching for knock is the WRONG answer with these cars. You can easily over-shoot your ignition goal and cause catastrophic event.

Direct Injection Control

Direct Injection Control. Our tuning gives us complete control over everything the ECM has the ability to control. Which means we can alter the direct injection events. Why would we do this? Mazda calibrated these cars for more than just enthusiasts. They calibrated these cars for everyone, including that one guy who won't change his oil, revs his car up ice cold, and puts the cheapest fuel you can find in the tank. What does this have to do with the direct injection? Everything!.  Mazda implemented a 2x DUAL spray with the Skyactiv. A Main pahse (power) and Cylinder cooling phase. Altering the correct tables can provide Cleaner Mixture control over the entire RPM range, while maximizing MPG when you want it.

Complete Closed Loop System

These ECM's have been calibrated to be in FULL TIME Closed Loop, regardless of pedal input. Some tuners don't agree with that, some tuners may fight it. It's a blessing in disguise. There is a very specific reason for full time closed loop control. Full time adaptability, under all circumstances. Rather than fighting this system, we accent it, and multiply it's ability to keep everything stable. Full time closed loop allows for *perfect* Wide open throttle Air fueling, very precise ignition timing control, and very sensitive Knock control.

Knock Control

Knock control with the skyactiv is unlike any other Mazda. The knock sensor is in control, all the time, regardless of RPM. Unlike other Mazdas, the Skyactiv DOES NOT turn the knock sensor off after a certain RPM. It has wide-range feedback all the way past 7500 RPM (tested!). However the ECU also uses the knock sensor to ADD Ignition timing, not just remove it!.
