A while ago I had a few issues with my ECU and since then I've had an error complaining about the post cat lambda sensor (something about the voltage being too high).
I've changed the sensor multiple times but the error just comes back after the engine warms up.
There's a few posts on here where people have had the sensor mapped out and I was wondering if this is easy to do?
I can read /write the map easily enough with nefmoto, I just need to know what software is required to map it out?
Also if it can be mapped out with no issues, what is the purpose of it in the first place?
