So I know how much grams a second to expect the engine to consume at idle and tune the maf transfer function correctly for maf mode to work correctly.

Why do you need to know g/s? Just install the MAF sensor and log it.

But if it's plugged in and logging, doesn't that tell you the answer?

Typically, the B engines draw around 4.5 - 5.5 grams / sec at idle in a stock configuration.
So, now that you possess this information, what fabulous thing will you do with it? |

I am guessing people are not well familiar with the maf as with map. In comparison it would be like taking a map sensor, not calibrating it or anything, just installing it and running it. Tech wants to calibrate it before he tunes it.

Maf not so much as the installs can easily change the curve, and they are non linear output. Anyways just to finish this thread my answer I sought for I had finally came across and is noted in here how to find out. For anyone else that later on looks and needs help. https://docs.google.com/document/d/1...li4/edit?pli=1 |
This thread is an interesting combination of trolling and over-thinking the subject.
Trolling because no civilization which has advanced beyond fire and the wheel concerns itself with mass flow in absolute units. Over-thinking because it's not necessary to attempt to predict every possible operating condition when we have the ability to observe the engine's operating AFR with the use of an EGO sensor and plot trends using spreadsheet software. |
