MEGASQUIRT V3 IGNITION DRIVER DOWNLOAD

It is recommended that V2. This means that as the missing tooth passes the sensor it doesnt trigger the ECU untill the fall from the next tooth Tooth 1. As this is a 4cyl there are four outer holes. If 5th and 6th logic channels are required, build additional transistor circuits with the inputs JS5 and JS4 and route the output from the circuits to spare output pins of your choice. An Oscilloscope or an adapter for the sound card of your PC with suitable software eg Creative Wave Studio can greatly assist in fine tuning the input load resistors.

Older models fitted with dizzy cap delivering spark, later ones with wasted spark. Getting a good clean signal into MS is essential or you will spend hours trying to track down problems later on. Simply set the system up as a 6 cylinder engine running wasted spark, this will fire the 3 spark outputs Spark A, B and C every deg of crank rotation. The SOHC usually runs a distributor. Turn the engine until cylinder 1 should fire. Tweaking the input resistor values as per the earlier version of the V3 VR conditioners in the circuits above, results in a much cleaner signal as shown below.

The rotary engine has a leading and a trailing ignition 2 plugs per rotor the leading fires first then the trailing fires a few degrees later. This mode is for use with a single coil distributor allowing you to control your timing if you have a single coil firing through a distributor megaasquirt, an MSD 6A amplifier, etc.

Finding Edis 4 in North America: See HERE for settings. A locked distributor is one that has mechanical and vacuum advance either removed or “locked” out so that the trigger signal occurs at the same crankshaft angle at all rpms. For a 4cy sequential setup you would need to have 4 of these circuits rather than the 2 below, simply repeat the additions for Spark C and D so Spark C point to connect the 1K resistor is: There is also an aluminium one to avoid as well.

After Market Electronic Ignition. Use the ‘R’ revision since the earlier ‘L’ revision has reliability issues.

Ignition Control with MegaSquirt-II EFI controller

With an MSD box, the ignition module wires you need to know about are:. Assuming you have obtained a igbition wheel, you need to establish the correct relationship igniiton the VR megwsquirt and disc. Once you get the CAS in, double check that it’s lined up.

The code acts as a front end ahead of the normal MegasquirtnSpark system. An Oscilloscope or an adapter for the sound card of your PC with suitable software eg Creative Wave Studio can greatly assist in fine tuning the input load resistors.

The V board makes it easy to access 3 logic ignition channels, but as the board was not designed for DIY modifications, any other changes can be more awkward than the DIY V3. It can be handy to get 2 sets so you can practice a little first. Multi-spark is currently under test with MSnS-extra firmware. Many sections are like an instruction manual and some close to advertising. The outputs will NOT work correctly if you choose: Location of the VR sensor varies. So to be safe simply drill and file out a slot for a new DB15 connector where the LED holes are in the front panel.

For a rotary, we want a max advance of maybe 40 deg BTDC at high revs and low kPa, and we want a cranking angle of 0 degrees. It is usually set up for the cranking angle when there are enough teeth. Either a single second pickup and wheel with 2 teeth, or two pick-ups with a single tooth can be used as a second input into MSnS. Typical trigger discs from a Ford VR Sensor. Megasquiet distributor may have to be modified to ensure that the spark is delivered to the correct cylinder.

Because it doesn’t need a camshaft position sensor, EDIS is a ihnition easy way to replace distributor ignitions when retrofitting older engines with a modern computer programmable ignition, but we now recommend directly driving the coil packs from the MS ECU using the VB FET’s. MS3 users can use the MS3X output card which gives 8 channels of logic spark without the need for any customisation. Remember you only need to fit the same amount of VB’s as you require outputs.
