WARNING: This page is about a different car, the 2020 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The ignition timing cannot be adjusted.
The M-MDS is required to verify the ignition timing.

Prepare for the engine tune-up. (See ENGINE TUNE-UP PREPARATION .)
Verify the ignition timing (M-MDS PID: SPARKADV) using the PID/data monitor function of the M-MDS. (See PCM INSPECTION .)
