Car running VERY Lean

[midge]

i fitted a lumention afr meter and it goes off the scale, i am running a hill power chip but even after unplugging it and putting it back its exactly the same, tried a mates ecu with gunnerchip and its still the same..

so where do i start? fuel pump isnt noisy, injectors are ment to have only done 72kish

I'd suggest whipping the injectors out and having them flow tested

FPR ok?

Just to ask perhaps a silly question or two...

Have you had any trouble with it that's made you think you need to check the afr?

Is the machine definitely working? If it's the same on two different ECUs with different maps then... ??

i had the car rr'd where it made 157bhp @fly was 150@wheels last time, the graph showed ti at 15-16.0 so i got the meter to try the re-set on the chip to check that was wrong.. the meter was reading wrong because the lambda was ****ed, cars running spot on now!
