How long does it take to tune a kat w/ safc?

[Structure240sx]

when the motor is completely cold start it up. give it enough throttle to rev right at 1000rpms. veiw the air flow % and enter that as the second number in dec. air.

next rev to 2000rpms. enter this air flow % as the last number and the throttle % as the first number

ok just to make sure i understand, the dec. air setting says:

Thr %Ne01 %Ne02 %

so the air flow % i get from 1000rpm i enter in for Ne01, and the air flow % i get for 2000rpm i enter in for Ne02 right? and the Thr % is the same as what i put in for Ne01 %?

[Structure240sx]

you got it right except the thr%. what ever the thr% is to hold the engine at 2000rpms is the value you enter
