Make sure neither is set as that could stop it working. The Speedo Corrector is of medium level difficulty.

By two wire sensor I am referring to a reluctor style that outputs an alternating wave form Results 1 to 18 of If the signal is correctot moving between 0V correcotr 12V it doesn’t need a pull up or corrdctor down resistor. There goes that idea.

The Speedo Corrector will also work with electronic tachos that take their feed from the ECU ie all cars with engine management. Speedo Corrector Get your electronic speedo reading accurately! If the Corrector is fitted to a car with a digital speedo, some lag may occur jaycxr the action of the speedo. To set the speedo you will need an accurate reference. That seems low and a bit daft really seeing as I’m pretty sure the 3 wire speed sensor puts out battery voltage!

Nup, never seen the LED flash. Cheap electronic kit Correct inaccurate speedos in standard cars Correct inaccurate speedo caused by changed differential or gearbox ratios Correct inaccurate speedo caused by changed tyre diameters Intercept and modify the speed signal, eg to power steering weight control or auto trans controller Also corrects tachometers.


BB code is On. The plugs join with a pretty positive feeling, so I very much doubt there’s a problem with the signal getting to the board. However, note that some mechanical speedos have an electronic output that sends speed information from the speedo to the ECU, so if you want to alter the ECU speed input, you can still do so.

Last edited by cue; at Its rated to a 50V input voltage anyway, assuming you have a speedo corrector mkii http: Now going much faster with TypeR power. I won’t try to explain how to set it up as the instructions do that and it’s too hard to describe but all it involves is turning a rotary switch and moving a jumper around until the speedo moves.

This module alters the s Ah well, will have to keep looking at the gps, no biggie lol Last edited by Box; at Soft roaders represent an excellent compromise between the needs of the hardcore 4×4 user and the convenience of a city hatchback.

This needs to be done with the unit connected and powered-up. With this improved model, the input setup selection can be spdedo selected and it also features an LED indicator to show when the input signal is being received.

This is because most speedos read fast often by about 5 per cent. Is the LED normally suppose to come on when the unit powers up? Please contact us if you need to check whether Next Day delivery applies to your area Can the connectors you put on be connected to the wrong ones?

Just in case its a spredo one.

Remove the speedo wire so the corrector can go in-line with the sender – cluster.

It says in the booklet that the LED blinks when the correct signal is picked up and if not to speeo the jumper around until it starts blinking.

Additional delivery time may result for some deliveries. You can have the speed sensor removed and sperdo someone turn it over slowly by hand as you measure the signal output voltage with a multimeter And you’re sure that the output of the 3 wire sensor connected to the dash doesn’t work?
