Tyre Pressure Monitoring

[richy22]

The latest addition to Monaco will be this little kit ....

Tyre Pressure Montitoring system.

Basically I have an In-Car PC that does GPS/Mp3's/Video and few other bits and pieces and soemone modified the above kit to enable you to connect it to the PC and it warns you if any of the tyres are running low on pressure (basically an early warning system for punctures and such like)

To get an idea of what it does...

Mine should be similar to his but with a Renault 3dish drawing same as this

Why would you want to know this you may ask??

Well because I want too and because I can!!

Possibly the ONLY Sport (bar 1 i know of) with TPMS


We have also been developing a Rear parking sensor indicator thingy

Not everyones cup of tea but still developed it because we could

Nice set up there.

I'll stick with checking them manually. I check them once a week anyway & it only takes five mins.

Yep that works too. quite a few race teams run these. Le Mans cars and such like and they have proven a vital safety aid, i.e

Driver:- bombing along at 200mph... hang on wtf is that beepeing?? Radio pits....

Pit crew:- Told him so slow down now and just as he slowed up the tyre burst as he had a puncture. saved him from going off the track at over 200mph.

All cars will have to come with this soon anyway, think its law in America (no surprise!) that all cars have to come with them now.

i like it, i looked at them on the tweeks website but its effort with 2 sets of wheels

loving the reverse sensor aswell

Can't see it personally.

Too many variables, if it was law, you'd have to put a ban on buying aftermarket wheels etc.

Different tyres can require different pressures so how does the computer know which is correct?

Plus on all the cars they've come on in the UK over the recent years they've always gone wrong.

It will be a requirement from 2012 for all EU cars to be fitted with TPMS. It has been law in the USA since September 2007.

Not really. Direct systems just involve swapping the sensors to the new wheels, or buying a new set of sensors. As the USA has required this for approximately a year, most rim manufacturers are ensuring their rims will cope with wheel sensors.

Indirect systems can cope providing rolling circumference doesn't change, I believe.

Different tyres can require different pressures so how does the computer know which is correct?

ECUs can be recoded by dealer, some systems automatically set limits based on cold inflation pressures when the system was calibrated etc etc. There are plenty of ways round this.

Bit of dramatisation! Whilst most Renault owners will acknowledge the TPMS fitted to Renaults is rubbish, there's plenty of decent systems out there.

By indirect, are you refering to systems that monitor rotational speed using the ABS sensors? (Like BMW for example). If so, it's to do with the relative speed between the wheels on the same axel.

Even then, they're nothing but trouble.

ECUs can be recoded by dealer, some systems automatically set limits based on cold inflation pressures when the system was calibrated etc etc. There are plenty of ways round this.

So now you have to goto a dealer if you want some different tyres?

Never seen it on a Renault tbf

"Never seen it on a Renault tbf"

- it would probably break or fall off anyway !

Cheers James! was hoping someone else would back me up!
