I've not been near the car all week (been working in London, can't wait to leave this underground malarkey behind!)

Anyone got any thoughts to this I can start with over the weekend?

So, I've found that I get an IOT/IDC dip when I hit afr 11.75 (or 0.80-0.79 lambda)

I've also found LALIUSMN (Minimum measurable lambda?) - It is originally set to 0.7996, maybe just a coincidence that my issues are here though...

Next step I guess would be try the oem injectors and see if the same thing occurs.

Well... As to the how's and whys, I can't answer them.

But lowering LALIUSMN seems to have sorted this issue.
