How long does it ordinarily take to install the Sports V.S.D.?

It will generally take approximately 60 minutes to complete the installation, although it may take longer or less time depending upon the configuration of your vehicle.

On which vehicles can the Sports V.S.D. be installed?

The product can be installed on vehicles with 3, 4, 5, 6 and 8 cylinder engines and engine computers utilizing 2, 4, 8 and 16 pulses. The product cannot be installed on vehicles where a speed pulse signal is not available on the engine computer, unless the vehicle is equipped with an aftermarket speed pulse sensor.

Do I need wiring for the product ?

Yes. You need wiring for IGN(power), AND(ground), SP(speedometer) signal and TA(tachometer) signal from the ECU(Engine Computer Unit) of your vehicle. You will also need wiring to connect to the BAT+ ( which connects to 12V battery) and ILM, (which supplies 12V when the instrument panel lights are ON). If the Speed Governor Release is to be utilized, you need to connect the inner and outer connector terminals which are included in the Sports V.S.D.kit.

Do I have to obtain the connector from an auto-parts or hardware store in order to install the product?

No, you don't. All of the necessary connectors for the installation are included in the Sports V.S.D. kit.

I have a diesel vehicle. Will the speed pulse signal work ?

Yes, if the speed pulse wire from the control unit is connected to the ECU.

Why doesn't the tachometer display function (TA) work on diesel vehicles ?

Diesel vehicles have no spark plugs, so there is no standard electrical signal output from vehicle to measure engine revolution speed. (Some recent diesel vehicles have electronic controls.)

If TA signal is not available from the engine computer unit (ECU), can I obtain TA signal from the igniter of the vehicle's engine?

Yes, you can.

Can the Speed Governor Release be used on all vehicle's models?

The Speed Governor Release cannot be used on Toyota ECT vehicles.

What are IGN, GND, SP, TA, ILM and +B ?

IGN = 12V positive switched on when ignition is on.
GND = Ground
SP = Speed Signal.
TA = Engine Revolution Signal.
ILM = provides 12V positive switched on when the panel lights are ON.
+B = 12V positive.

When SP(TA) display is not needed, must the SP or TA wire be attached to the ECU leads?

No.

Can I install the product on vehicles with an aftermarket ECU?

You may be able to connect to the speed pulse signal. However, we are not responsible for any damages to your vehicle or personal injuries that may result from such installation.

Can the product be used on cars with a modified ignition system ?

We are not responsible for any such installation.

Can I use the speed pulse signal from my GPS navigation system?

We cannot guarantee the proper functioning of the product when the speed pulse signal is taken from the GPS navigation system.

Can the product be adjusted to function with nonstandard size wheels?

No.

If the vehicle spins its wheels in the drag race mode, is the wheel spin counted as distance provided?

Yes, it is.
