The MAF500 datalog looks like the calibration was not uploaded with the MAF500 setting, and also the datalog does not match the calibration using their IDS. Are you sure you uploaded?

What setting in the calibration did you use for the MAF500?

Nothing to worry about. The tracing is for display only so the table in the ECU is read correctly. I have updated for the next release so it displays correctly.

This table?


Is your air change under 15 g/s on overrun? Seems likely. In that case I'll make the changes to the factory tables.

It is a beta feature. It is not fully understood and has been included for testing by several users. After evaluation it will either be incorporated into all vehicles or removed.

The error indicates there is a problem with the HPFP wiring, connector or HPFP itself.

Apologies, this will be re-enabled for the next release.

Axis is l/s.

The index is correct - the maximum is about 340 g/s.
