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
https://log.malonetuning.com/chart/244833#H8KLCADDoXY%2FXAIDdcOMQQrDgyAQBcOQwrvCuB7CiybCpsOQwrPCiAtbByPCpDHDqAhpT8OfaMKgdFHCl8O%2Fwr%2FDucKjNXvDhMOnPcKsw4h9woplw4sMwoTCgVouMcKFNx4RwpjDhxXCkyVkVcKsc8O8w4XDrR5ywrMUw7xMDTLDkg9oARIGGEHDgQQ3A0zCnsOrQjFvS8KgeiNVw5t9w6NwwrlOwrXCmcKDQ8OuLMOZw6NlwoURKBXDvCdDV2RXRFfDlCnDpgPCjxPCvsKpFQEAAA%3D%3D

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.

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
