Nistune Forums

My lc1 reads ubber rich

the dyno reads around 12.2 afrs

and at the same time the lc1 reads in the 9's

is there something else that should be done

ive read many threads on innovate motorsports forum and they say this is normal because the tail pipe O2 can pick up small bits of fresh air where as the o2 installed into the dump pipe doesnt

but its very concerning having that much difference

anyone else having this problem
oh and ive re calibrated a few times and it still does it

getting my red car dyno tuned this week. i'll plug both up and let you know how it goes

did you check that logworks reports the same afrs as nistune does?

I believe it does from memory matt


been ages since ive run it on the laptop and looked


ive sort of excepted it now days

what about recalibrating your LC-1

I found i had to do that today when I was taking logs

Done it a few times matt


i was thinking its giving a false reading because its too close to the turbo


its about 12 inches away from it (further then the factory one)
