XDI DIRECT COIL IGNITION

The Direct Ignition Advantage
What separates Electromotive's sophisticated Engine Control from those of other manufacturers, is its patented, industry leading Direct Fire Ignition system. With both the stand-alone XDI ignition systems and the Total Engine Control systems, Electromotive utilizes a 58-tooth crank trigger wheel. This “high resolution” signal feeds continuous information to custom ignition chips so that error is virtually eliminated. This "high resolution" circuitry is used to accurately determine both the coil charge time and the Ignition Event in actual angular values (degrees of crank rotation). This eliminates the dynamic error that the competition suffers from. Others may claim ΌΊ degree accuracy, but without this accurate crankshaft position information, they’re just wishing.
Every Engine Control system from Electromotive uses multiple ignition coils and advanced, automatically adjusting dwell circuits to assure the coils are fully charged every time. The powerful spark of this patented system delivers this full spark energy directly to the plugs without misfires. Unlike multi-spark CD systems that from around 3000 RPM just give you a single very short duration spark, Electromotive puts a full 150mJ of spark energy to the plugs with a spark duration more than ten times the duration of a CD spark from idle to 9600 RPM. This long duration spark makes more power!
FIRST SOLUTION: the C.D.(Capacitive Discharge) Ignition. This Ignition does not CHARGE the Ignition Coil, rather it uses the 1:100 Winding ratio as a TRANSFORMER. First the 12 volts of your electrical system is converted to 200-500 volts and stored in a CAPACITOR, when the SPARK is needed the CAPACITOR is DISCHARGED into your Ignition Coil, Instantly producing a SPARK of 30,000 to 50,000 volts with a DURATION of only 0.1 to 0.3 milliseconds (0.0003 seconds)... this is NOT A LONG SPARK !
SUPERIOR SOLUTION: Multiple Coil Ignition Systems. By using an Ignition Coil for every pair of companion Cylinders, the TIME available to CHARGE an Ignition coil goes up by a factor of 4 on an 8cyl Engine. This allows you to use the advantages inherent in an INDUCTIVE SPARK... this uses only enough voltage to ARC the gap of the Spark Plug and dissipates the rest of the SPARK ENERGY in DURATION ! up to over 2 Milliseconds (that's over 90 degrees at 8000 RPM) This MAKES MORE POWER !
So, no matter which of our Products you choose, you will always know that the Ignition System is STATE OF THE ART and READY FOR ANYTHING !

XDI delivers more power because:

Spark timing is precisely controlled under all conditions, including rapid engine
acceleration
Crank trigger eliminates spark scatter due to gear lash and timing chain stretch or timing belt stretch
Accurate spark timing allows sustained engine operation closer to peak power
timing
100% spark energy to 9600 RPM on 6 cylinder and 12,000 RPM on 4 & 8 cylinder applications (at 12 volts)
Operation up to 20,000 RPM (at higher battery voltage)
Long, 1000+ microsecond spark duration - 60+° duration at 10,000 RPM!
