I have since changed my lambda sensor as it was dead and now all is well. Only see the 2 greens.
I think it was something to do with the transition from closed loop to open loop operation of the ECU.
Any help?

have you checked all pipes and hosing (ie all clips tightend to max (including inlet to turbo which is hidden away a bit)). A bit of unmetered air getting in to the system can cause lean running and DET. But then again your AFR says all ok! Still worth checking.

Unless you've got a wideband, don't assume the AFR is OK because the factory lambda sensor says so. These things indicate "very rich" at something like 13.8:1 and at the top end of the map, you'll need something like 11:1 to keep the car from detting...

If you wind the boost down to say.. 0.6 bar does it still happen.. If not I suspect you have an early block thats a high compression one.
Unfortunately the only cure is to run at lower boost, or change the short block.
They run upto about .8 bar before detting.

I put some injector cleaner in and it seems to be better so i will use the current tank of fuel and try doing it again, fingers crossed it was a slightly blocked injector.
I've posted this question in general but no replys so i'll try here, has any body fitted a GReddy FMIC to a classic if so are they any good and how much cutting to fit, theres someone selling them on ebay
Cheers Lee
