Title: MAF readings Leon 1.8T AMK
Post by: Dejw0089 on January 16, 2019, 11:33:48 AM
Hi
I has very weird maf readings.I has max 170g/s -> 612kg/h maf readings.
I has tuned car but reading is to low and in log I see maf voltage reading 170 g/s -> 4.35 V but when I look into MLHFM map I see 612 kg/h -> 3,87V so my question is what is wrong?

my log

My mlofs is ori 200
so I can have those readings on car with power more than 210 HP?

I read this but didn't solve my problem. I don't want more flow only i think my flow is to low for my power. On non modified car i has 210 hp and low maf reading is correct?

If you care about power numbers you should be using a dyno or at least a HP estimator based on rpm vs time.

MAF numbers mean nothing.

You're short a bit of HP.

For some unknown reason you didn't log timing or IAT or really anything else to help diagnose the issue.

Sorry for incomplete log I just start loging and I see on other logs maf readings 190-210 g/s so I just think about my readings and why is so low
