why would you want to map the eml light out any way its a safe thing would you say that if you engine went not saying it will but surly its better safe than sorry:shrug: just get a wayne block or oxygen senser adapter to sort it:)

They don't delete it they just change the values to allow for the extra flow..it would still bring up a code if it failed.
 
wayne block or oxygen senser adapter this is a good think till you can go stage 2 and cheaper and save the light cuming on:)
 
Thats what I done for the few months before I had it mapped out, might put it back in tho as the block makes the lambda sit at a better angle so it doesn't touch the heatshield like it does now :doh:
 
Thanks for that info, something i'd not consider otherwise. How did you figure that it was the MAF meter at fault? They are completely unlinked aren't they :shrug:.

Touch wood it isn't 'error 666: car dying, you're funked' tomorrow :D

Its all part of the fueling system i think. Im guessing the maf tells the ecu what to expect and if those values dont meet at the lamda end it throws a wobbly.

Ran my sports cat for 4 years at 2 stages of tune and never had an emissions issue/ sailed through each mot.
