VCDI-21
Supported bikes:
Suzuki: RGV250
Aprilia: RS250
VCDI-21 is upgraded
VCDI-20 unit.
Technical data:
-
minimum revs 200 RPM
-
maximum revs 20000 RPM
-
minimum supply voltage 8 Volts
-
maximum supply voltage 20 Volts
-
current draw 25mA
-
max. supply voltage for 1 minute 40 Volts
- dimensions (LxWxH) 72x50x27mm
Circuit is protected against reverse supply voltage
(wrong connection).
Features:
- two channel isolated input
- 2 custom programmable curves (
TPS33%,TPS66%,TPS100% )
- store and load function for 2 ignition curve
sets
- TPS function ( 3D interpolation between programmed
curves )
- programmable on/off output for
solenoid (RPM and TPS dependent)
- programmable duty cycle (pulsed) output for solenoid (RPM
and TPS dependent)
- shift light output
- shift kill
- map switch for changing ignition map while
riding
- tachometer output
- easy and fast programming on the field, via
handheld programmer
- programming while machine running - you can
immediately see effects
- each curve can be set with 4 to 12 rev points
- each curve point can be programmed with 100rpm
steps and 0,1deg steps
- three stage rev limit ( retard timing, reduced
spark, spark off )
- signal delay compensation
- instant monitoring of rev and angle, via handheld
programmer
- fast processing for high accuracy - delays from
1us
- theoretical maximum revs at 20000RPM (tested with
pulse generator and oscilloscope)
- timing calculation for every 1RPM change (1000,
1001, 1002, .. .., 9805, 9806, ...)
