how do people turn off and on a digital speedo

[philip121]

out of interest hows this done/ regards a off on swich connected to a digital odometer

Call in at your local Police Station and ask at the front desk. They will love to hear from you.

so its a crime just finding information /

YES

The problem with a digital speedo is it is likely used for more ECU data than just speed.

The thought process is the same for digital speedo vs cable speedo.

If it sees extensive time off road then you can log book it and apply for a refund pretty easily.

My wagon isn't fast enough to need a speedo :/

[tweake]

most have speed as an input into ecu for a few different functions. hence if its doesn't get an input it can go into limp mode.
auto gearbox needs speed input especially for the lock up clutch. newer ones need it for the airbags and traction control etc.

also many vehicles now do not have a gearbox sender, speed data comes from the abs system speed rings on each wheel.
some still have gearbox sender as a backup in case of abs failure.

changing mileage requires hacking of cluster unit and possibly other modules depending on the protection systems the manufacture has.

transport industry has a system for tracking with gps and it records off road use so you can get your tax back.
cannot recall cost.

very interesting hacking digital odometer clusters/ is one thing/ involved / off on swich is another less involved perhaps/

[tweake]

on/off switch won't work for modern vehicles.

[philip121]

why not depends on where the off on swich is placed///////// or am I wrong///

if you turn off the speed sensors the ecu won't let the engine run.
if you turn off the speedo itself the ecu still records the milage.

with some vehicles if the brake lights are not working you can't start the engine as the brake lights are an ecu input and ecu wants all inputs working.

I see / this would be with some digital speedos light diesel trucks I take/ but not all/ as I have been told many people have swiches in there diesel trucks/ its a matter of finding an outo electric person to put one in/ some will most wont/

[stealth]

I think many people do have switches in their trucks but most will be an older style analog speedo, I don't know anyone with a digital speedo that has bothered with switches esp if you have to get an Auto sparkey to figure it out - might cost more than its worth.

[NJV6]

Not to mention I doubt many decent sparky would be prepared to do it.

Pay your way and stop being a tight prick or stay at home

[philip121]

Pay your rip off RUGS //////// Apart from big trucks/ diesel light trucks and cars are gone/ petrol is the way/ because of RUGS and high reg costs

[NJV6]

Is that why Ranger, Hilux and Triton were 3 of the top 5 sales lately? All diesel... if it wasn’t for soot particles Diesel is certainly the way to go, unfortunately they are sooty so get hamstrung with emissions gear. Economy and driveability is unbeatable!

And your precious petrol already has the road users built in which is in my opinion worse as I have to pay to maintain the roadsyou drive on with the petrol in my V8 jetboat!

If you don’t pay your way who then grizzles about the state of the roads??

[philip121]

Because of rugs/ and registration there is little savings / to be worth using a diesel/ diesel or better at loads and toeing etc/ its a good concept but the govenments adds ons have buggered it////// Why don't you put a diesel in your jet boat/

[dvk-kp]

Why don't you put a diesel in your jet boat/

Cos he wants his jetboat to have power and throttle response!

[philip121]

but diesels are so perfect and ahead of petrol engines/ so we have been told/ if they cant run a jet boat at speed / what a let down/ PETROL WINS they are a tractor engine/
