Do It Yourself CDI TCI for single cylinder
AC fed CDI
This circuit turns an AC-CDI into a DC-CDI. An AC-CDI needs a working STATOR to charge. If the stator fails, let it be rewind or buy a new one is pretty expensive! This circuit was designed to bypass the faulty stator by making High Voltage (around 200 to 400V) directly from the +12v battery. When […]

CDI reprogramming Version 7 separate the firmware in the ROM (firmware is protected) from the ignition timing in the EPROM (advance map is not protected). The ignition timing is stored in the internal data EEPROM meaning that you can change the advance curve yourself as often as you want… Just draw the new curve in

This AC-CDI is EOL Features Programmable AC-CDI For ONE or TWO* cylinders For [2 strokes engines] and for [4 strokes engines with wasted spark*] * On 4stk engines with 1 pickup on the crankshaft, one spark occur at compression stroke and one at exhaust stroke. Firing in the exhaust stroke is a wasted spark. Hence
plus Firmware. On AC-CDI v7.9, DC-CDI v7.9 or DC-CDI v2.1 the tacho output available at RB5/PIN11/TP1 can drive a tachometer. The signal is a +5volts level and 5% Duty Cycle signal: but some tachometers need a +12v level at 50% DutyCycle signal ! In order to work with such tachometers I created a small microprocessor

This Tester is EOL (end of live) and has been replaced by CDI Tester v6.2 Design to simulate pickup at different RPM to test TCI, ACCDI, DCCDI, Tachometers, Power valves and ignition coils. And to extract the advance curve from a Digital TCI or CDI. PICKUP SIMULATION Range 1000 to 24,000RPM in 24 steps.
