Subaru MAF scaling ?

Post by panel » Fri Aug 05, 2016 11:27 pm

Have any of you that have done a Subaru conversion done any MAF scaling after you've put in a different intake/inlet pipe ?

I was told that every modification you make on the intake pre and post MAF will change the airflow metering, so you'll need a new MAF scaling.

So...that would make it exactly like like SD or alpha-n, or even carburetors, right?
Mod something, you retune.
That jibes with everything I have ever seen.
The Factory ECU has some ability to learn around imperfect readings in most cases.
