Im in perth, still no fix, had car completely apart

did you try another cluster?

did you try another cluster?

yeah got a new cluster, put all wires back together, tried everything, going to see if a new sensor fixes it

same with mine, mine seems to be off by about 20kmph, it only start budging from 0, once i get the speed up to around 20kmph+.

btw, im using a gtr cluster instead for my r33 gtst.If the ecu gets the signal from speedo, not sure if it'll be harmful to the engine on the long run. Been using it for 6 months so far no prob. Friends always teases me wth am i going so slow, i told him my speedo is in MPH lol.

I wrote a thread on how to tweak your speedo by small amounts, there is a MP/H to KM/H conversion too but that might not help you.

There is another tutorial about adjusting your speedo using an electronic calibrator from Jaycar, that may help you...

ECU pulls current speed from the wheel speed sensors, not the gearbox.. dash gets it from the gearbox. That's what I'm sure of anyway.

my car has no ABS - so has no wheels sensors ....

I got this same problem, my speedo and ODO dont work, but everything else does, so im assuming its my speedo sensor in the gearbox (which im a bout to go down and inspect).

I have an Apexi PFC with hand controller, I used to get accurate speed readings on that before, but the speed readings are on 0 constantly now, so i assume that the speedo sensor (gearbox) gives the cluster (dash) and ECU the readings. In regards to the posts above, I dont think that the ECU gets readings from wheel sensors (on R33s).
