AC-CDI 16F628 v7.9

NEWS APR.2019: v7.9 software is out there for many years now and has help a lot of DIYselfer. To continue to maintain the quality and allow improvements while developing others products as V9 wireless AC-CDI, CDI tester and soon TCI versions, I have chosen to switch V7.9 software into a paid product. A free trial version is available for download in the Shop section. CHARACTERISTICS. Adaptable to other single-cylinder .

AC-CDI ANALOG

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 .

Pickup Simulator v3

Design to simulate a pickup coil at different RPM to test CDIs, Tachometers, Power valves and ignition coils. Range: from  300 to 30000 RPM (V2.x) Range: from 1000 to 30000 RPM (V3.3)   Download. Simulator v2.3 Software Schematic Parts list Circuit board Eagle files PIC-LCD-DAC pinouts PIC 16F628A .HEX .PDF .TXT .PDF .JPG .SCH .BRD .TXTLCD datasheet Version 2.3 is free to use, version 3 and above are only .

AC-CDI 16F628 v6.7

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 .

AC-CDI Honda XR400

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 .
