Hey!

The mechanic odometers look really, old. You know. The digital meters in new cars is a LOT prettier than the odometer we got in our cars. Is there a possibility to do a swap? Someone maybe have tried this?

im actually very interested in this too.. hrm anyone hve any ideas?

The main problem is that newer cars use CAMBUS and/or LIN where as our cars use OBD-I (or OBD-II for facelift in some countries) networks. The different networks are not compatible. So you need to find a car with OBD-I and a digital odometer.

I'm not looking at digitizing the Dashboard but I am looking at putting in some digital guages in the 2nd DIN under my 1 DIN Radio.

I'm looking at putting in a Volt meter (Seven Segment Led showing 99.99V) and an Ammeter (Showing 99.99A).

I also want to modify the Circuit to show me Oil Temperature and Oil Pressure (999.9 Degrees and Bar/PSI.)

I have the Circuit for Voltmeter and I will use this with a Shunt to get me Amps (Car can go over 60 Amps and most meters are up to 10 Amps)

I have chosen the & segment LED's as I aim to place them behind a Smoked Perspex so it looks black with only the Digits showing through.
I have also found the Circuit to out put to LCD's but then you would require a back light to see it at night.

If any one has information on how the Stock Temperature and Oil Pressure Sensors work (Volt per Degree, Resistance per Degree) I would greatly appreciate any information.
If I cannot use the Stock ones I'll have to Purchase After market Sensors.

I'll be starting a thread Soon on upgrading the Electrical System (Big 3 plus more), Sound System and Digital Gages.

Also look on the web there are hundreds of electronic projects out there for the Car.
(Dome Dimmers, Digital Ganges, LED Rev Counters just to name a few that I have looked at.)

I'll also tell you in my Thread what Circuits I have tried and how good/Bad thy are until I get what I'm happy with.

Problem with the digital odometers in cars is that they run through the PCM, or in some cases the BCM on cars. The Celica's I believe is a straight cable driven odometer and as such wouldn't work with anything that's out there currently. There's no aftermarket solution that I know of.

My 96-98 Curren is Electronic, No straight cable driven odometer

Yea, facelift 3sge Celica is electric also.

This is what I'm working on for my Car

Sorry if this is a Hijack of your thread but this is the closest post to what I'm working on.

the GT odometers are not cable driven as far as i know.. i pulled out my gauge cluster and the only thing that connects to it from the back are wire harnesses, no cable.



here's something for ya

yup, no cable in my dash

The odometer in my car is not straight cable driven. So, is it possible? I hate the mechanic odometer, its so "90's"

where do you find those?
