Gearbox Speed Sensor & Reverse Signal

[kristafa]

doing a conversion, my bmw has electronic speedo, r32 (gtst) box has cable driven speedo. I also know that the ECU is aware of the wheel speed - i assume that this is through another sensor in the final drive. Down in the gearbox there is a plug which would be for reverse lights..

basically i need as much information as possible.. i am thinking of buying an apexi rev/speed meter to take over from my bmw speedo.. this would wire into the ecu that gets the signal from the gearbox?

Please help:

* I dont know too much about the 32 gear box, and what sensors exist in there..

* I need to know what speed my car is doing

* can i get a signal converter from somewhere to convert the cable to a digital interface so i can keep the bmw speedo working

* I need reverse lights

can anybody advise a solution for this saga ??? - thanks. chris.

Use an R33 speedo sensor, they are electonic. You may have to change the frequency to suite the BMW speedo, Jaycar have a kit for that.

be careful i think you will find the R33 GTST box will have the larger speedo sender in it.

get the electronic sender from the R31 RB30E skyline manual.

sorry couldnt send pm, but what was the soloution to this, as iam doing similar thing.

atm i have got this made in japan kinda recitifier thing ontop of the cable driven speed sensor, it outputs a signal i beleive. and doing a ohms test there is resistance.

but it seems neither my speedo or rev speed meter can pick up any signal from it, and i have cycled through 2p-160p of signal picking, and still nothing.??

any help ? what other electric speed sensor fits in there ?

if anyone cares, the signal must be grounded to the ecu , not to the battery. problem solved
