I want to order air to fuel ratio meter, and a boost meter for my car. Will this be usefull.I mean will it work in my car. Skoda 1.9 TDI. If yes then can u send me some manuals please or instructions please

air fuel meter wont work as it takes its feed from a lambda probe signal which our current diesels dont have.

Boost meter will but you need one with a large enough range and it wont measure neg pressure (vacuum).

Thanks Lummox. Can u give me some example or some links for this type of meters. Actually i dont know any thing about this kind of meters. And i want to install one.

Thanks a lot

If you want to fit one to a TDI, i don't think it will work.

I fitted one to a VW Corrado G60. The feed wire splices into the signal from the Lambda probe & then another wire is connected to any earth point. I think mine was from autometers.com. You can mount the gauge any where in the cockpit, but I used a factory option gauge trim which mounted in the centre console.
