TCI v10


A programmable ignition is extremely valuable in repair work as it fit a wide array of bikes.
It’s especially helpful if original parts has been discontinued or is overpriced.
And of course it is required if you want to tune your engine.

Features

  • Programmable TCI.
  • For ONE or TWO* cylinders
  • For [2 strokes engines] and for [4 strokes engines with wasted spark*]

    * On 4stk engines with 1 pickup on the crankshaft, one spark occur at compression stroke and one at exhaust stroke. Firing in the exhaust stroke is a wasted spark. Hence the name…

  • 80MHz MicroController control unit
  • Firmware included
  • Easy programming with Micro USB Type B connection and terminal console
  • Compatible Windows, Linux, Mac
  • Non volatile configuration
  • One programmable ignition curve
  • Engine speed from 10 to 16,000 RPM.
  • 0 deg advance from 1 to 500 RPM (to avoid kickback)
  • Adjustable timing in 13 steps from 500 to 16,000RPM
  • Improves timing curve
  • Removes stock Rev limiter
  • 1 input for an inductive pickup (VR) or Hall type or Points
  • Pickup polarity can be set to Positive, Negative or Automatic detection.
  • 1 output for an INDUCTIVE coil type >1.5ohm.
  • Kill switch input
  • Tachometer output
  • Coil current: Max: 15A
  • Over Voltage Protection: Max 430v
  • Coil protection: shut off after 2sec without signal
  • Power supply voltage DC 10 to 16 volts
  • Quiescent current 30mA
  • Protected against reverse supply voltage
  • Available as a ready-to-use device in the SHOP section
  • Dimensions: 100 x 60 x 25mm (3.9 x 2.4 x 1inch)
  • Plastic box potted for Electrical insulation, Protecting components from mechanical shock and vibration, thermal shock or moisture.
  • 15cm(6”) 1.5mm2(16AWG) wires soldered with 6.3mm automotive female connector
  • Made in France

Cylinders:

Single-cylinder:
If there is one separate pickup:
=> This TCI works.
If there are 2 separate pickups (one for low RPM and one for High RPM):
=> This TCI works and uses only the High RPM pickup.
If the engine works with Missing Teeth:
=> This TCI will NOT works

* Twin-cylinders at 360° crankshaft angle:
The engine works with WASTED spark.
If there is ONE twin coil:
=> This TCI works.

See: TCI compatibility

Remember that ignition coils are different from TCI to CDI system
– CDI coils have low inductance and impedance around 0.5-0.8ohm
– TCI coils have higher inductance and impedance around 1-5ohm


Pickup:

– 1 input for inductive pickup with 1 signal per crank rev.
– Pickup must puts out 3 to 30Vac
Points, reluctors, Hall sensor, optical sensors can also be used as long as they give only 1 pulse per revolution.
– This TCI is not compatible with multi-pulses pickup or missing tooth wheel.

How to calculate the Pickup Position?

Pickup Polarity

Check the polarity of the pickup (Negative then Positive/NP or the opposite PN) with a Needle galvanometer (in milliAmp position) while kicking.

For a better understanding, this video can help.


Rev Limiter:

The last RPM value you enter is the “rev limit” that stop all sparks.

  1. Dear Thiery ,
    Do there comes also a version where the schematic and the excel file are on the web , and where it is possible to buy only the software , and and the rest is DIY ?

    Thanck you ,
    Gerard

  2. Dear Thiery ,
    I’d like to purchase this item, but it seems to be out of stock.
    Could you tell me when it will be possible to purchase one?

    thank you.
    Rick
