VersaTuner | 2.5 Tune | MX-5 NC

So you've gone through the heart transplant procedure of swapping in your torque filled displacement hog of a 2.5L engine. It's truly the perfect fit for an enjoyable, durable power-band that will keep you smiling. But you won't get far or fast without a calibration and we've perfected it. Heaps of torque and a top end that want's to scream.  

This calibration includes the review and revision of your data logs/calibration. If needed, we will revise the file 4 times to get you dialed in. Any updates beyond this will only be needed if you make changes to your hardware. This additional touch-up work doesn't require a new purchase, we offer this at $20 per session. 

With modern OEM management, your results are limited by the parameter boundaries Mazda has put in place. Even with the addition of bolt-on components like higher flowing exhausts and cold air sourcing intakes, the factory computer will only compensate with fuel - and sometimes not even enough! The real power comes with Ignition timing, Valve Timing, Fuel Tuning, Throttle control and a number of other parameters that help to unlock the otherwise tethered setup.

How does this work? With the purchase of this specific product you'll receive all of the hardware and software required to calibrate your naturally aspirated, bolt-on or entirely stock NC MX-5. Once your VT Lite kit arrives, there are short instructions to follow in order to collect information for Fab9 to build your calibration.

What if I have bigger plans to modify my car in the future? Great! This is a preferred platform for manipulation of the OEM ECU and it's not limited to our shelf performance calibrations. Custom tuning can be done in the same fashion as other platforms have done in the past. With our Pro Tuning service, you'll collect data on your specific configuration and we can issue tailored remapping to suit your unique vehicle.
