Lambda light on= restricted power

[T5frankie]

my lambda light come on again, it was on with the original ecu, when i put the mapped ecu in there was no stored lambda light on and the car was flying, then the lambda light come on and instantly the car was back to standard power, boosting to halfway into the white still fast but standard fast, i tried the standard ecu again and the lambda light was still on and boosted the same and drove the same as the mapped one did now, will i be able to use the bcs or will it have to be mbc to bypass the ecu's control to get the power back? is there a way of turning the lambda off? obviously i cant get it mapped again

Mine threw up a lambda light and it was TCV (BCS) I changed that £8 and it restored everything once i cleared codes.

sounds like you have a problem
I dont think you can turn off the lambda light, you need to fix the problem

how did you clear the codes mate?

probably cos i'm running greens and a 3.8 bar reg, its confused lol

Took it to HLM mate.

it may well be overfuelling, but that wont throw a lambda light.
you have a sensor issue

for example,I binned my carbon canistor some time ago, but if you unplug the valve that goes to the canistor, it throws up the light

even a boost leak can bring the light on

the car was running spot on, it is running spot on i just have the lambda light on which is not letting me use my map, the whole of the 2 years i had my v70r it had the lambda light on but i was using an mbc

the lambda light is about emissions, not boost control

[T5frankie]

the lambda light is about emissions, not boost control

i don't care if the emissions are high, they are bound to be running big injectors at 3,8 bar, the car runs so smooth, no hesitation, bloody volvos

the cel light means the ecu isn't happy. Read the codes, fix the problem then it'll be happy

have u got a pilots licence now!

i needed one for a few miles mate lol..........duck

how do you read the codes on my 850r? it doesnt connect to my code reader or a laptop with vol-fcr either

car was flying yeah!

[graemewelch]

fix it properly. get codes read. even get live data if need be. no point having a remap if bypass the boost control. get it running right and youll get what you want out of it

you may be surprised mate you only have a low power output now lol

not easy to read codes like the new stuff mate

still to much for u tho fast boy
