How To Ignore Af Reading

[rnbguy]

i dont know who mods this forum, and how a post gets locked without a chance for the initial question to be explained

anyway...

im curious how i can get the ecu to not panic when it sees a bad (over lean or rich) reading for the OXYGEN sensor, not the mass air reading (aproached using safc)...

i know all about safc and power fc etc but the ecu is going into R&R from the oxygen sensor

hi

your topic was locked because its been covered a hundred times before, you need to search

the ecu does not go into R&R from the oxygen sensor

it does not panic from the AF reading

you dont need to ignore the AF reading

the ecu goes into R&R or (panic) from too much air coming into the engine, via the AFM (or airflow meter)

that is, you turn the boost up, the engine uses up more air, so the AFM voltage increases

the ecu then see's this and panics.

an safc will fix it

a powerfc will fix it

a remap of the std ecu will fix it

turning the boost down will fix

changing the oxygen sensor wont fix it

changing the airflow meter wont fix it

disconnecting the oxygen sensor wont fix it

disconnecting the airflow meter wont fix it

ignoring the 02 sensor wont fix it

It was locked as i stated clearled

Although, there are 100's of threads on R&R - please try searching (with R&R)

Same as this.

Thanks.
