The timer will show you A/F ratio but without a wideband O2 sensor, you will only get narrowband readings. You will need something alot more accurate than that. The best thing about a wideband is that you can upload your fuel curve to a laptop and see where you get lean spots and just how lean those spots are.
I CONTRIBUTED TO THE WIKI! ah... turbo. I love the turbo, the boost, the speed, the sound. and its all better when you do it yourself. cheaper too.
