What should the ignition timing be on a Miata?
The piston is already beginning to travel back down the cylinder when the combustion occurrs. The piston is therefore travelling a shorter distance under power which translates to power loss. The timing on a stock Miata should be set to 10° before top dead center (10° BTDC) ±1° at 850 RPM idle speed.
Why are the ignition wires on my Miata not working?
Common Problem! The factory ignition wires on the Miata only seem to last between 30,000 and 50,000 miles. If you are experiencing misfiring and hesitation and you haven’t changed your wires, this is most likely the cause. Change the wires! In case you forget which plugs is which, refer to the firing order diagram below.
What should the idle RPM be on a Miata?
Factory spec for the Miata specifies standard timing as 10° before top dead center (10° BTDC) ±1° at idle speed(850 rpm). If your timing is advanced more than this, you may experience pinging under some conditions. Dirty spark plugs Metallic burr in cylinder
What can I do to improve my Mazda Miata?
There are tons of modifications you can do to improve your Miata’s handling. While wheels and tires come into play here, the most common handling upgrades are to the suspension. Stiffening your car’s suspension will generally make your MX-5 handle better (to a point).
How do you MegaSquirt a Mazda Miata diyautotune?
Run MSnS-E and the “2nd Trigger” Wheel Decoder option (where the missing tooth on the wheel decoder comes from a second sensor, usually cam position). The CAS has a CMP and CKP signal, so you take the outputs of each and run them into the MegaSquirt.
Where does the spark output go on a Mazda Miata?
The top resistor goes to IGN and the bottom resistor goes to IAC2B.When wiring up your ECU later: Spark Output A will come out on pin36, and Spark Output B will come out on pin31. NOTE– If you’re modding up an MS-I PCBv2.2 ECU you can use the documentation at this link to use your stock ignitors.
Do you need dwell control on Mazda Miata MegaTune?
In MegaTune’s Ignition Settings, ‘Spark Output Inverted’ must be set to YES. And you should enable Dwell Control. Skipping either of these will cook your BIP373’s, and possibly your coils. (more info on MegaTune setup below). What about everything else???
What kind of resistor do I need for Mazda Miata?
Install a 470 ohm 1/4w resistor between the right side (non-band) end of D1 and the left leg (banded end) of D9. You’ll start with an MS1 V3.57 set up for Hall / opto triggering. This means you’ll have JP1 in the 2-3 position and J1 in the 1-2 position.
