NEWS FEB.2019: Please update to the last version V79R16C1. Major correction for RPM below 1500RPM Huge improvement of precision. (10times better!) CHARACTERISTICS. Adaptable to other single-cylinder bikes. Accuracy (0.15°/8000RPM). Firmware source unavailable (only .HEX). Advance curve is in EEPROM and can be freely modify Need a working charging coil for the capacitor. Need a 6 or 12v battery DOWNLOAD PIC 16F628A 600 to 30000rpm Make the PCB: PCB Eagle .
v2.2 Characteristics. Easy to build. or ready to use in the SHOP. Advance curve slightly adjustable. Need a working charging coil for the capacitor. Don’t need a battery No rev-limiter Limitations. This CDI only does the ignition task, it doesn’t use any safety like neutral and sidestand. Connect directly Neutral switch wire to Neutral indicator. If you need “Side-stand security” then connect Sidestand switch to KILL wire of this .
This version is discontinued. Consider to build v7 instead! Characteristics. Adaptable to other single-cylinder bikes. High precision (0.07 degree). Preprogrammed for XT400/550/2strokes (84 or 106 points). Software source unavailable (only .HEX). Need a working charging coil for the capacitor. Need a battery DOWNLOAD PIC 16F628A v6.7 1500 to 40000rpm To make the PCB PCB Eagle v6 files To build the CDI Schematic Partlist To burn the PIC Softwares .
ADAPTATION to fit a Honda XR250 / XR400R Done by Characteristics Based on AC-CDI PIC16f84 v5.4 For single. 1 advance curve. No kickback. Introduction Andrew has build a AC-CDI for his 2002 XR400R. Mains changes are: – He use a 2.2uf 380v capacitor, and the same configuration of the rectifier diodes he saw into the original cdi. – No battery is used and the cdi is directly .
