USER MANUAL
VCDI-04 AND VCDI-04s DIGITAL IGNITION
VCDI-04 is designed to work with original Yamaha flywheel generator pickups on aircooled
E model, LC and YPVS.
VCDI-04s is designed to work with original Suzuki RG500 pickup.
TECHNICAL DATA
Limit values:
minimum revs 200 RPM
maximum revs 20000 RPM
minimum supply voltage 8 Volts
maximum supply voltage 20 Volts
max. supply voltage for 1 minute 40 Volts
Circuit is protected against reverse supply voltage (wrong connection).
Features:
- it is upgrade to existing ignition system
- ten custom programmable curves
- store and load function for ten custom curves
- easy and fast programming on the field, via hand held programmer
- programming while machine running - you can immediately see effects
- each curve can be set in 4 to 10 curve points
- three stage rev limit (retard timing, reduced spark, spark off)
- signal delay compensation
- instant monitoring of rev's and angle, via LCD(hand held programmer)
- fast processing for high accuracy - delays from 1us
- timing calculation for every 1 RPM change (1000, 1002, .. , 9805, 9806, ...)
Very important!
Resistor spark plugs must be used, because they produce less electromagnetic disturbances.

1. HOW TO ENTER MENU
VCDI must be connected to power supply, or start the bike. Connect VCDI unit to
programmer unit and wait few seconds for activation of programmer and then press enter
. With pressing + or - you can move through menu and with pressing enter you can
choose.
You can exit menu with choosing Exit Settings.
2. MENU ORGANISATION
Load Settings - load previously saved curve (from #1 to #10)
Save Settings - save new curve (from #1 to #10)
Ignition Curve - ignition curve parameters
Rev Limit - rev limit
Static Angle - static angle (stator position)
Compensation - signal delay compensation (from pickup to spark plug)
Pulse Width - output signal pulse width
Pulses Per Rev - number pulses per rev from pickup
Exit Settings
3. LOAD SETTINGS
Enter menu and move to Load Settings with pressing + or - and then press enter .
Now you can select position number of previously saved curve with pressing + or - and
then press enter .
4. SAVE SETTINGS
Enter menu and move to Save Settings with pressing + or - and then press enter .
Now you can select position number to which you want to save your curve with pressing +
or - and then press enter .
5. Change IGNITION CURVE
Enter menu and move to Ignition Curve with pressing + or - and then press enter .
Now you are in submenu for setting ignition curve.
Submenu organisation:
Nr. of Points - number of ignition curve points (from 4 to 10)
1) - first ignition curve point
2) - second ignition curve point
... ...
... ...
Exit Curve - exit submenu

Important!
To avoid wrong processing, don't make unreasonable curve course.
Every time you make any changes to ignition curve, it is automatically saved to #0 position.
Then you can save it to any other position number from #1 to #10.
Curve Example with six curve points:
5.1. Change NUMBER OF IGNITION CURVE POINTS
Move to Nr. of Points with pressing + or - and then press enter .
Now you can select number of ignition points, with pressing + or - and then press enter .
5.2. Change PARAMETERS OF IGNITION CURVE POINT
Move to point you want to change, with pressing + or - and then press enter .
Now you can change rev point with pressing + or - (in 100 rpm steps) and then press
enter .
Now you can change advance angle with pressing + or - (in 0.1deg steps) and then press
enter .

6. Change REV LIMIT
Enter menu and move to Rev Limit with pressing + or - and then press enter .
Now you can change rev limit with pressing + or - (in 100 rpm steps) and then press
enter .
7. Set STATIC ANGLE
Enter menu and move to Static Angle with pressing + or - and then press enter .
Now you can set static angle with pressing + or - (in 0.1deg steps) and then press enter .
More information's about static angle you can find in section 11.
8. COMPENSATION
It is compensation of signal delay from pickup to spark plugs. You can check this delay with
stroboscope lamp. Without this compensation, ignition advance angle decreasing with rising
revs.
This compensation helps that advance angles in ignition curve are real(more accurate).
How to check, if compensation is correct:
First you must set flat ignition curve. Then measure with stroboscope lamp, if mark at
flywheel moving when changing revs. If mark moving then you must change compensation
delay.
Change Compensation:
Enter menu and move to Compensation with pressing + or - and then press enter .
Now you can change compensation delay with pressing + or - and then press enter .
9. PULSE WIDTH
It is output pulse width (duration) in us. It affect on CDI triggering, charging and PV out
signal on CDI-RZ1 and CDI-RD500. Recommended setting is 200us or 100us.
Enter menu and move to Pulse Width with pressing + or - and then press enter .
Now you can change pulse width with pressing + or - (in 100us steps) and then press
enter .
10. PULSES PER REV
It is number of pulses per rev from pickup coil and is important for correct rev reading.
Setting is 2 for all twins with wasted spark ignition system.
Enter menu and move to Pulses Per Rev with pressing + or - and then press enter .
Now you can change nr. of pulses per rev with pressing + or - and then press enter .

11. MECHANICAL SETTINGS (Static Angle)
Static Angle is ignition advance angle, set with stator (generator).
Measure this angle with dial gauge. This measured Static Angle is your maximum advance
angle you can set with VCDI.
For example:
Measured Static Angle = 26.2deg (this angle you must enter in VCDI)
Important!
Every time you dismantle stator or flywheel, you must measure your Static Angle again!
Calculating mm to deg or vice versa:
Example - calculating mm to deg:
Bike: RD400E
R = 31mm (engine stroke divided by 2)
L = 115mm (conrod length)
T = 4mm (ignition advance in mm)

12. MONITORING
Connect VCDI unit to programmer unit and wait few seconds for activation of
programmer. Fist information displayed on the programmer is software version.
With programmer you can watch revs and calculated advance ignition angle.
Information!
You can connect or disconnect VCDI unit from processor unit any time you want, without
any harm. It is not important, if motor running or not and if power supply is connected or not.
Important!
Do not use too much force when connecting or disconnecting programmer unit!
13. ERROR REPORTS
Two errors can be displayed:
Program Memory Error - when program memory is corrupted. With this error present,
function of program could be faulty.
EEPROM Error - when eeprom memory is corrupted. All programmable data are stored in
eeprom memory (curve, rev limit...). With this error present, function of program could be
faulty. You must check all your settings and correct changed.

14. WIRING
aircooled and LC:
Important!
Power supply for VCDI must be connected to brown wire in fuse box - not directly to battery.
VCDI must be disconnected from power supply, with moving ignition switch to off position.
VCDI wont work, if your battery voltage is below 8 Volts.
Very important!
Resistor spark plugs must be used, because they produce less electromagnetic disturbances.

RZ350YPVS:
Important!
VCDI must be disconnected from power supply, with moving ignition switch to off position.
VCDI wont work, if your battery voltage is below 8 Volts.
