Speedo Wiring

[Alf]

I have done an R33 series 1 RB25 conversion into an 32 with a 33 GTR box (converted to rwd) that uses the 33 GTR elec speedo sensor.

I am no longer using the R32 mech speedo and replying on the PFC commander.

Can the wires from the speedo sensor run straight to the RB25 ECU instead of through the dash or does it require a pulse divider/multiplier?

Iv done the same thing put a 25box behind my 20 and i want to pick up the speed thru my power fc.

can this be done by wiring into the plug off the gear box?

I got the speedo on the pfc hand controler to work by connecting the speedo sender wiring straight to the ecu input.

The speedo is out by alot tho, i used a jaycar speedo corrector but has not reduced it enough. At the moment the speedo reads double the actual speed. (Im using a 4.3 diff btw)

I am about to wire in a pulse divider that will divide it by half making the jaycar kit useable.

I'll report back when this works.
