FIXED LAMBDA BUT NOT PULLING LIKE IT USED TO ?? IDEAS ?
Hi Guys
Just replaced the front lambda sensor on 52 plate bugeye wrx, before the sensor went it pulled in every gear and started to boost at just over 2k revs, Ive noticed after they have replaced the sensor, reset the ecu and removed the fualt code that its not boosting until about 3.5k and just doesnt feel the same as it did before the sensor broke. Ive done a faukt test on it to see if any faults are showing but its completly clear.
I only bought the car in Jan this year so wasnt sure if it had been mapped or not, do you think the reset could have wiped the map off if it was mapped ?
Ive bought some Millers PETROL POWER ECOMAX - ONE SHOT FUEL BOOST 250ML to see if system just needs a bit of a clean seen as it ran with faulty lambda for nearly 2 wks.
Any ideas ?

when andy f did my map he set the demisster so you can set it to half boost so when you reset the ecu its on half boost could be that who did your mapping if you have had it done
did they take the manifold off to replace the sensor if it was stuck (mine was stuck solid so manifold had to come off) as it may be leaking some were so not all the exhaust gases getting to the turbo

NO THE DIDNT TAKE MANIFOLD OFF BUT THEY HAD A RITE JOB TAKING IT OFF. iVE HAD A GOOD LISTEN AND CANT HEAR THE EXHAUST LEAKING ANYWHERE. AT A LOSS TO BE HONEST.

I didnt have any issues at all before the sensor packed in so I cant see it carboning up the up pipe in 2 wks, might be worth checking the sensor is in nice and tight they did look to be struggling with it tbh
