Thread: sr20vvl km/h signal from gearbox to ecu ??

Hi, i hope someone can help me?
I have a nissan sr20vvl in my "race' car.
Whe dont use a dashboard.
But i have information, that the ecu needs the km/h signal, otherwise the high rpm is stopped at 6900 rpm, and the vvl solenoid dont work.
( i have a ecu from Bill , Greece, with another doughterboard )
Does anyone knows, if the signal from the gearbox, can be connect straight to ecu, ore do need the dashboard?
I mean, does the dashboard , convert the signal?

Thanks a lott,

Peter Netherlands.

The speed sensor sends an analog signal to the speedometer, the speedometer converts it to a digital signal and sends it to the ECU.

What I did to get it work a non nissan vehicle with a 20VE swap, was to use a B14 speedo (just the circuit board), and wire it in as it would be in as it would normally be.

thanks, i gone try to get that part off my dashboard, and try to connect it.
Iff anyone knows witch wirring i have to connect, it will help me a lott.

Later i shall post here the type off my dashboard.
