Just seen a vi monitor in a magazine and it sounds like it does it all from finding faults and fixing them for you, to being an accurate rolling road also measuring all temps, to much to list really the website is www.vi-performance.co.uk I'm ordering mine tonight just wondering if anyone has one on here?

 

Gps systems are usually better. Another alternative is the gtech.
Don't trust the rpm signal stuff, you have to get it from the ecu signal 99% of the times, readings from the cigarette lighter are not the best.

 

This is powered straight from the ecu but has a good reputation from a lot of top car magazines here in the uk I'll have to see what its like when I get it.

 

straight from the ecu? you mean via OBDII i know that. Gotta see if it picks the rpms from there or does like other systems.
Check the gtech anyway.

 

Yeah sorry I'm not that good when it comes to cars what's the gtech like does it do the same as the vi?

 

Looks nice. Having your own OBD-II scan tool is almost a must with modern cars. Accelerometer and data storage ought to make it a really cool toy/tool.

Looks like it's only available in the UK, though.
