3 INSTLLTION NOTES (S Pro-rag 50mJ systems only) MOUNTING o not mount the unit where it will be exposed to water or other liquids, ensure the bottom condensation slots are unobstructed and oriented to permit gravity drain. Select a location away from intense heat and if required provide a source of cooling air to remove generated heat. Failure to use supplied rubber mounts will void warranty! Suitable replacement anti vibration mounts are M&W #MNT00. IGNITION LES o not use plain metal wire or carbon core ignition leads. Use spiral wound inductively suppressed metal core ignition leads such as those available from Magnecor SPRK PLUGS The use of use non resistor spark plugs (where possible) will greatly enhance ignition performance. In some installations the use of resistor spark plugs may be unavoidable. In these cases ensure they are not damaged by testing internal resistance value as part of regular maintenance. Open circuit or high resistance may cause failure of spark plug wires, ignition coils and I. The use surface discharge or semi surface discharge spark plugs are limited to naturally aspirated engines due to their large spark gaps. INSULTION PREUTIONS egrease spark plug insulators and coil/plug boots after handling to prevent tracking or insulation breakdown. Use (supplied) dielectric grease on spark plug insulators and coil/plug boots to increase insulation properties and ease installation/removal. Use of dielectric grease in main connector may reduce water ingress

4 WIRING & POWER SUPPLY M&W I systems are designed to blow the external fuse under conditions of over voltage or reverse polarity. Faults such as loose battery terminals, poor wiring or defective alternator/regulator may also cause for this to occur. Fitting a larger capacity fuse won t disable this feature, will void warranty and may cause irreparable damage to unit. Only fit the recommended size fuse! Main connector pins are designed to be roll crimped. Squeeze crimping or soldering will cause distortion possibly resulting in misfiring or incorrect I operation. Wire ignition system directly to battery. If required wire length exceeds recommendations use small paired battery cable (power and ground) to make up distance. o not rely on vehicle chassis to provide ground path. If connected to a high impedance supply shared with EU or its sensors erratic operation will be experienced. The use of voltage boosters is not recommended as they may cause improper operation. When using a total loss electrical system install either a 16V or 18V battery to ensure supply voltage does not drop below 1V. If using extended voltage batteries isolate them during charging to prevent excessive voltage reaching the I and EU. Use twisted shielded pair wire for all coil connections. Twisted pair wire must be used for power/ground. Keep coil wires one continuous length from I and do not fit any intermediate connectors into harness. ll coil negative wires must be joined at or in the cdi connector. Keep coil primary (I) wires away from HT leads, coil HV outlet and coil body to prevent a flashover occurring. TRIGGERING Trigger input & coil output numbers (letters) indicate I ignition sequence not cylinder number. Ignition channels may be fired in any sequence. 50mJ Pro-rag systems include a trigger edge selection input which defaults to falling edge ignition with nothing connected. To select rising edge ignition install a jumper wire between Trigger Edge and Signal Ground pins. Where the EU contains an inbuilt igniter it may be necessary to use rising edge ignition

5 If I trigger edge and EU ignition edge do not match timing will be erratic! POWER LEVEL SWITH To reduce ignition energy under low load conditions some M&W 50mJ units include an (active low) power level switch. o not manually activate this feature. Either install an adjustable Hobbs style manifold pressure switch or use a programmable output from the EU and wire so input is grounded as engine comes under load. TUNING I systems are edge triggered and not effected by dwell settings. M&W I systems may reduce combustion delay and percentage misfire requiring a reduction in ignition timing. The resulting changes in combustion characteristics may also require alterations to fuel flow. Set EU ignition delay to zero and tune engine as required. lways re tune both fuel and timing curves after installing I ignition. THO OUTPUT The tacho output provides a 50% duty cycle square wave signal at battery supply voltage. This will work with most aftermarket digital tacho s however earlier types and those designed for coil negative triggering may not read accurately. LE INITOR fter applying power to switch wire the LE will illuminate for 1 second and extinguish. The LE will then flash briefly with each consecutive trigger event received (it may be necessary to view the LE directly on axis). repeated double flash of the LE may indicate a possible faulty ignition coil, faulty wiring, low supply voltage or damage to the I

6 TESTING The I may be tested by momentarily grounding the trigger inputs causing the LE to flash and corresponding ignition coil to spark. o not conduct this test without grounded spark plugs installed! more comprehensive test procedure may be found on our web site SFETY ue to extreme energy and voltage levels developed by M&W 50mJ ignition systems it is strongly recommended caution be taken to ensure personnel safety and prevent ignition component damage. pplication of power to ignition system in combination with an inadvertent ignition event from either EU being powered up/down or engine rotation can cause irreparable damage to ignition coils and I. Personnel in close proximity may suffer a painful electrical shock. 1. Install grounded metal studs in engine bay and transfer spark plug ends of HT leads to these between race events or at least when working on engine.. Install aircraft style guarded toggle switch in the I ignition switch wire circuit and disable it at all times except when running the engine. INSTLLTION PREUTIONS The main cause of I damage is conduction of high voltage to coil primary wiring. are must be taken due to the propensity for HV flashovers and insulation breakdown caused by I ignitions unique characteristics. It is essential to fully read and understand these instructions and have a comprehensive knowledge of automotive electrical systems before commencing installation.

7 IGNITION OILS (Pro-rag systems only) OIL SELETION For ultimate ignition energy and efficiency use coils specifically designed for I use such as the M&W #OI006. Ignition coils primarily designed for inductive ignition will limit I performance. OP OILS OP (coil on plug) coils were not designed for the energy levels and voltage potentials developed by M&W Pro-rag systems. Use OP coils at your own risk with 50mJ systems, O NOT use OP coils with 500mJ systems. Use resistive spark plugs with all OP coils. Keep plug gap <= 0.05 (0.6mm) to prevent coil & I damage. FERRITE I OILS Ferrite core cdi coils provide a lightweight solution for direct fire applications and give high secondary current however they may not be suitable for all applications due to their extremely short arc duration. The high level of EMI emitted by these coils may require additional shielding to prevent electrical interference with the EU or I. O NOT wire ferrite coils in parallel pairs! O NOT use Prufex brand Mercury coils or EM pencil coils under any circumstances! UTION! IGNITION OIL MGE MY OUR IF OPERTE WITH N EXESSIVE SPRK GP
