## Additional Steps for NA6 Vehicles

The NA6 1.6L vehicles which use an AFM instead of a MAF require a few additional modifications to run with a BMM ECU. A manual NA6 do not have a variable throttle position sensor (TPS) like the automatic NA6, later model NAs and all NBs. An NA6 also needs an external intake air temperature (IAT) sensor wired in as the AFM which has one inside is typically removed. They also require a jumper for the ECU to control the fuel pump which was previously the job of the air flow meter. Additionally, it is recommended to ground the sensors to the ECU rather than the chassis as detailed in the [NA6 ECU Grounding Guide](docs\11-Vehicle-Specific\Mazda-MX5-Miata\NA6-Grounding.md).

The first step is to disconnect the factory TPS sensor. **This is very important or it will cause a short circuit later.**. The TPS sensor location is shown in the image below.

If using a 36-2 trigger wheel instead, the first setting would be 36/2 and the advance will likely be different so check with the manufacturer. In the case of a 36-2T trigger wheel for an ATI damper, the advance angle should be around 148 degrees.

These settings will likely get the car started with the Mazda 323 timing wheel however the trigger angle advance may need to be iterated to perfectly match the timing on your car. To check or set the base timing, set the timing to fixed in TunerStudio and use a timing light on the crank to measure the timing. If the timing is not 10 degrees BTDC, iterate the trigger angle advance in TS until it is spot on. This is covered in "Set Base Timing" within the [Miata Quick Start Guide](docs\11-Vehicle-Specific\Mazda-MX5-Miata\11-Miata-MX5-Quick-Start.md).

Now after ensuring your timing is reverted back to dynamic in TS, the installation should now be complete!
