MAF Sensor Scalings

From MS4X Wiki
Revision as of 17:30, 17 September 2019 by Sda2 (talk | contribs)

We decided to publish often used MAF sensor scalings. This will make fuel tuning even easier.

Please keep in mind that you have to apply the MAF hack to your firmware binary when exceeding 1024kgh.

Note: The MS4x ECUs do NOT convert the ADC return value into voltage, but keep the digital 8bit value and convert it directly into airmass.

This is the scale of the M54B30 OEM MAF sensor.
