What should the EGO settins for a wideband be set at, i have a Vems wideband not clue what they should be but i think they are my problem as i have tweeked them a bit up and down and they do make a differance. Sorry my problem is at cruise my afrs are going between 13.5 and 15.5 and car is learching.

Did you set the protocol in MegaTune Configurator?

I tend to find these are best for Squit issues:

The ECU needs calibrating so that it reads the correct AFR from the wideband lambda sensor. This is an essential first step.

There are a number of different algorithms used for wideband EGO control. Without knowing which code version you are running it's impossible to say what effect tweaking the numbers will have.

Easiest way is to post your MSQ file and a datalog capturing the hunting behaviour.
