5.3 Ignition settings 5 SETTING UP A BASIC CONFIGURATION
Ford Coyote This motor also uses a 36-1 crank wheel, but you set up the cam trigger under the VVT settings
instead of directly. As with other Ford 36-1 wheels, you may need to use the 10K resistor across CKP+ and CKP-
to avoid loss of sync at high RPM.
• Ignition input capture will depend on the crank sensor wiring.
• Trigger wheel arrangement: Dual wheel with missing teeth
• Trigger wheel teeth: 36
• Missing teeth: 1
• Tooth #1 angle: 400
• Main wheel speed: Crank wheel
• Second trigger active on: Rising edge
To complete the cam wheel settings, you will need to set the cam decoder to “Ford Coyote” under the VVT Settings
menu.
Toyota 2JZ-GTE These settings are for the US market turbo motor that does not have VVT. These engines
have a 12 tooth crank wheel called an NE sensor plus two one tooth cam sensors called G sensors. These settings
use the “G1” sensor; for the “G2” sensor, add 360 degrees to the Tooth #1 Angle. The later VVT motors use the
hard coded 2JZ-VVT spark mode. Pre-VVT versions of the non turbo motor often used a 24 tooth cam wheel in
place of the 12 tooth crank wheel, but the settings are similar. The active edge settings assume you have the
grounded (common) wires connected to CKP- and CMP-. Reverse wiring the sensors will reverse which edges are
active.
• Ignition input capture: Falling Edge
• Trigger wheel arrangement: Dual wheel
• Trigger wheel teeth: 12
• Tooth #1 angle: 16
• Main wheel speed: Crank wheel
• Second trigger active on: Rising edge
• And every rotation of: Cam
5.3.4.17 Other wheel arrangements The examples shown here are not an exhaustive list of all the combina-
tions that are possible. For other arrangements of crank and cam wheels, you will need to apply the principles
here to your install.
5.3.5 EDIS and EDIS Multispark
Ford’s Electronic Distributorless Ignition System (EDIS) is an ignition system that does not require a cam position
signal. It can function with just a variable reluctor (VR) sensor and a 36-1 tooth crank wheel (36-1 means “36 teeth
minus one”, and refers to 36 evenly spaced teeth, one of which has been removed), it will not work with other
pattern wheels or hall sensors.
Because it doesn’t need a camshaft position sensor, EDIS is a particularly easy way to replace distributor
ignitions when retrofitting older engines with a modern computer programmable ignition. The EDIS modules are
very reliable and the system works well. The EDIS module itself handles all the decoding of the toothed wheel and
sends one pulse per cylinder to the MS3Pro. The code optionally supports the use of a cam sensor in addition to
the EDIS system and then supports sequential fuel.
If your engine already has a different trigger wheel setup, consider using that before retro-fitting EDIS - many
OEM tooth patterns are already supported in MS3Pro. We generally only recommend EDIS mode on the MS3Pro
if the engine is already fitted with a complete, working EDIS setup.
