Hi. Does anyone know if the Greddy a/f ratio gauge comes with the wideband O2 sensor?

Thanks!

 

it doesn't it comes with a narrow band

 

good enough to tune my pfc?

 

Nope. A wideband O2 is what you can trust tuning your engine with. The Trust A/F gauge is a bit better than the factory O2 readings, but nowhere near the accuracy of a wideband. Check out what the dudes in Japan like Dragon and Jspecwhoya are running with. Wideband is pricey, but worth it. Find some buddies that might want to split the cost of a wideband O2 setup.

 

thanks :bigok:

 

WB02 is expensive but alot cheaper than an engine rebuild :bigthumg:
