hi does anyone know how a air / fuel ration meter, ie a gauge showing if the engine is runnning lean or rich would be fitted to a rs turbo efi cvh.
i have herd that they connect to a 12v power source and then a signal wire joins onto where the hugo sensor, but i dont think the cvh has this sensor on the exhaust manifold. can anyone help before i go and buy one, thanks

 

If your car has no HEGO or EGO you will need to tap and fit a lug into exhaust with a size of 18mm X1.5mm for the lamda sensor, as it uses this to get the info, if it already has a sensor use this one as it is easier.
