Raider R150 tachometer for BRT solution

Raider R150 tachometer is a digital design that works only with the OEM DC-CDI. The input signal pulses for it to work came from one of the output pins of the MCU inside the black box.

Many motorcycle mod junkie that fits aftermarket compatible ignition controller like the BRT, kitti and others do not have that pulse to make the tachometer work again, Hence only some modification is needed.

Figure 1 shows the circuit that may able to use to control and or make the tachometer works and uses LM2917N which is a frequency to voltage converter entirely useful on thise analog tachometer made by TYPE R.

CIRCUIT DESCRIPTION

The signal pin is connected to the primary input of the ignition coil. The meter connection to be use is meter (-) and will be connected to the wire that was supposedly connected on the CDI pin. which is pin 5 wire..calibration is done by VR1, and your done.


CONSTRUCTION

figure 2 shows the typical layout of the circuit.

In RAIDER150, the tachometer signal came from inside the original cdi, One pin of the MCU is the one that send signal to the tachometer circuit inside the raider panel..

"In tagalog, sa madaling salita..sa raider150 lamang ho gagana ang tachometer dahil ang nagbibigay ng signal dito ay galing mismo sa loob ng cdi nila at isa sa mga paa ng MCU yon..hindi sa ignition coil, at hindi din kung san san man..

Kung gagamit kayo ng ibang CDI maliban sa raider150 na original..hindi ho gagana ang tachometer maliban na lang kung may gagawa ng circuit sa itaas para dyan i tap ang tachometer ng raider panel.

salamat sa reply sir ! :D

if gumamit ako ng cdi ng raider to other mc ok lang sir?? basta tama yung sa pin outs to wiring nya? salamat ulit!

lahat po ba ginagalaw yung pins para umandar yung mc at rpm?
