how to tune a Apexi TT

[jaqule]

I played with the O2 v and A/F and now it doesn't read right , how do I tune it back to the way it was , a the moment on A/F it just flashes green/red and on O2 it reads around 3.25 up and down around that .

thanks in advance

The A/F ratios on the Apexi Turbo Timer is only a theoretical value based on the O2 voltage readings..

You can download a manual for it from the USA Apexi website and read up a bit more on it..
