I have a spare gutted dizzy that would work fine to drive the oil pump.

I knew I should have drilled and tapped all four runners on my IDF manifold. I only have one tapped for vacuum.

Ignition Control

However, there are blocked off vacuum ports below the butterflies in each Weber barrel. Those should work, no? When the edge of a tooth piece of ferrous metal passes them at high speed and at a very close megasquirt v3 ignition Gap of 0.

The following diagram shows what happens when the VR jumpers on the V3. The trigger points where the signal goes through the line on the positive going slope are shown in megasquirt v3 ignition.

Common MegaSquirt Modifications -

The time between the trigger points is megasquirt v3 ignition untill the missing tooth comes passed the sensor. The gap has increased a little not fully as the wave returns to the line but as it has to wait untill the next positively going slope the next gap is also decoded as another missing tooth.

This time the negative side of the slope is megasquirt v3 ignition as the trigger edge. This means that as the missing tooth megasquirt v3 ignition the sensor it doesnt trigger the ECU untill the fall from the next tooth Tooth 1. Adjust both the pots fully counter-clockwise ccw as a starting point, they don't physically stop turning, you will hear them click when they are fully one way.

Ignition Control with MegaSquirt-II EFI controller

Generally the pots end up either fully ccw or a few turns clockwise from there. This megasquirt v3 ignition the same circuit for a V2. Another option is to build the VR conditioner from the V3.


megasquirt v3 ignition Many Mazda and Toyota engines utilise Nippondenso ignition which uses a dual wheel crank angle sensor CAS which has one 24 tooth wheel and a 2 or single tooth second wheel. This is also needed to run a 5cylinder engine in COP mode it can also be used inventively to give 4 cyl COP or could be used with the dual pickup crank trigger from SDS for 4cyl wasted spark. Depending on what sensor you have depends on the input stage, but all sensors will need an opto isolator setup like megasquirt v3 ignition unless your using the VR conditioner circuit.

Will the MegaSquirt work with my stock ignition system?

No problems here, no special decoding required. This is also usually a toothed wheel with a VR sensor and is mounted on the crank pulley up front, or the flywheel on the back megasquirt v3 ignition the engine. Gents, Could I pick your brain further if I may.


The attached is my interpretation of the wiring instructions for the microsquirt. For plug wires, I took my megasquirt v3 ignition NGK wires and just cut them to length, using these new distributor ends that fit nicely on the coil terminals.

I have no info on using any other tachometers, but if you'd like to use the stock current-sensing tach in your Z, it's very simple. Wire the BW wire that powered your ballast resistor to the GW wire that came megasquirt v3 ignition the ballast resistor. Megasquirt Search In.

If they arent installed well you need to install them See V3 Assembly guide on Megasquirt.For Megasquirt-1 and Megasquirt-2 megasquirt v3 ignition is common to customise the ECU to install high-current ignition drivers (BIP) internally.
