Default Cossie rich off boost

Just taken the cossie out for the first proper run out.
Is running fine at idle and on boost spot on lambda.
When running at cruise off boost the lands lights I have fitted to mine run all the way down past rich until there's no LEDs left
I have fitted new phase and cps sensors, wouldn't have thought they could make it run that rich?

Could try your coolant temp sensor.

Are you sure it has been mapped ok aswell? or has it just started doing it?

It has just started doing it.
It has been fine otherwise just used shotloads of fuel obviously!
I don't know what is contolling the LEDs as it was fitted when I got the car (richm's old car)

I would get it checked at a reputable tuners using a proper wideband kit not the cheap stuff on the Market, personally!

I very much doubt its cheap stuff jimbo admittedly it isn't ever gonna be as accurate as a wideband kit but the fact it's showing rich and has used loads of fuel kinda points to it running rich.
I could do with getting it on some rollers for a check over at some point but haven't got the spare cash at the moment and as I dont know of any decent tuners down this end of the country with a 4x4 rolling road it would also mean driving it across country to someone who can look at it.

Sorry completely missed the using lots more fuel bit teach me for skimming over

Well as above then possibly the coolant temp, this will go to a fail safe point iirc -55degrees if it is faulty, might be worth trying, bit of an arse to do but will give you something to do

Yeah tell me about it replaced it a couple of years ago, not something I'm looking forward to repeating! Also gotta take starter out as it seems to be sticking and not engauging pretty much all of the time, job for tonights sorted then
