Frankenso MazdaMiataNA6 pnp

The Frankenso board was designed to be used on Mazda Miata NA6 as a plug-and-play solution.

Stage 0

Everything stock running rusEFI ECU

All stock sensors, no extra wires, no extra hoses - just lift the carpet and plug rusEFI box instead of OEM ECU.

Timing, fuel control based on VAF/MAF, programmable check engine light, A/C compressor control. Online tuning using TunerStudio.

SD card logging, LCD screen and joystick because why not.

Stage 1

Stage 0 + External wide band controller, wide band oxygen sensor, external MAP sensor

Stage 2

Stage 1 + TPS

Bench testing options

On NA6 Spark #1 and Spark #3 would audibly click if you use bench Spark Test button. Because of wasted spark wiring Spark #2 and Spark #4 are not expected to click.

On NA6 Injector #1 and Injector #2 would audibly click if you use bench Injector Test button. Because of batch injection wiring Injectors #3 and #4 are not expected to click.

All you need is a relatively quiet surroundings and you would hear both spark and injectors. Injectors are louder, spark is less loud but also totally audible. Both Test buttons are expected to produce three clicks a second after you press the button in the software.

Wideband O2 sensor wire WBO

You would really need a wideband sensor. Here is the middle plug pinout to wire an external wideband controller - +12v would feed external controller and analog output signal would provide rusEFI ECU with air/fuel ratio information.

A small flat screw driver and small pliers allow you to move side latches and open the cap. Insert supplied extra pin wire (pin on this picture) and close the latches. Done!
