CDI FIXED ADVANCE APRILIA SCARB/ AMICO/SR/RALLY/GULLIV-MINARELLI,All of which should have the following make and number on there flywheel (Which can be found on the flywheel face).DUCATI FLYWHEEL 31.1063/ APRILIA 82.12600/82.12685 . PM Tuning Ignitor re-mapped CDI ignition unit for most 50cc-70cc autos explained. No complex re- wiring or re-timing. Simply unplug the original CDI and plug in the new CDI for optimum ignition boost improved spark lead and intensity without in built fixed rev limiter /restrictor. Various auto manufactures build in a fixed rpm ceiling into there CDI boxs, and no amount of tuning or bolt on performance parts will see an increase in power after a certain rpm example Hondas X8R/S+SFX use this idea as part of there 30 MPH restriction in the UK. PM tuning can offer for most autos a race coil + re-mapped CDI box available with or without variable spark advance trim (engine cannot be damaged) the adjustable RPM rev limiter, once pre-set to the desired rpm ceiling, (E.G. 30mph legal limit) can then be switched on or off by means of a toggle switch or small key type switch (2x keys supplied). The reason for this feature was originally for certain European countries. For example German police units use a mobile dyno if you were unfortunate to be pulled over you could simply switch on the rev limiter, this would then restrict the machine to the legal power limit leaving the police baffled after seeing a tuned machine just out accelerate a Porsche. Other advantages of this system are your machine can be loaned to a friend safe in the knowledge that he/she cannot over rev your engine when switched on. All PM Tuning Ignitor CDIÆs are designed for plug and play installation some have a small amount of ignition timing delay trim along with rev limiter adjustment with on off switch. 12VOLT CDIÆs with optional supplementary power supply black / red 12v power lead. This feature allows the CDI to maintain maximum power output throughout the entire rev range regardless on the performance of the flywheel / stator. Small power drain requires a minimum of 8v to work effectively. Variable advance Start up advance is managed by a micro processor with integrated automatic correction to natural delay of the stator/flywheel it will improve the engines performance especially on hard acceleration. Requires no mechanical adjustment to the stator/flywheel. Fitting: Locate original CDI usually under front panel (Honda x8r) or rear side left hand panel on most. Remove original CDI and replace with Ignitor CDI plugging into original wiring loom. Remove the original coil and replace if your kit includes new race coil. For 12v supplementary option only Connect to original loom wires; connect red positive + power lead to the positive pole of the ignition switch and black negative-lead to ground/earth. : WARNING do not connect red lead directly to the battery.
