Hi guys
ive just bought a Gunsons gastester to set up my Co as the car smells very rich and always a handy bit of kit to have around.
whilst calibrating it i decided to find the factory setting only to find my inner wing sticker has gone that apparently has the info according to my haynes manual
Soo i started googling it only to find a web full of posts saying "leave it alone"

not much help.
so does anyone on here know the factory setting ?
thanks in advance
1983 944 lux 80k on the clock i had a reading of 1.6-1.7
