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 .
A adaptation from Features Based on : PIC16f628 v6.5 for singlecylinder. 1 advance curve programmed. No RPM limitation. Introduction. This adaptation was design for a DR600 SJ model 1988 that use a CDI with 2 sensors, this adaptation does not work on previous models with only one single sensor. The working is quite similar to the XT 600, just reverse two wires.. Be aware that the pickup .
Adaptation done by: Characteristics Same software as AC-CDI v7 For single cyl. 1 advance curve. No alternator. DOWNLOAD PIC 16F628A v2.1 DC-CDI Schematic PCB Board layout Partlist Eagle files How does it works? Software is the same as AC-CDI version 7 Only the Hardware is different: High Voltage is no more coming from a charging coil, but it’s generating from the 12v battery. A UC3845 .
A great job from Ivan A Gritskov from Russia. Synoptic. working. Ivan has used the Atmel DC-CDI originaly designed for a XT600, and modify it in order to fit a DRZ400S. He also used a Tiny2313 which has the same pinout a 89C2051, except the Reset pin which work in a opposite way. The software has been re-writed using BASIC-AVR and the advance curve has been changed .
