The description, axis and scaling for the table on the left is totally wrong.
The right hand table is better as the axis is airflow Hz and it is best to use unit scaling for this table for our purposes. It is not a MAF scaling table though, rather a MAF constant table related to airflow pulse per stroke. This table should actually be left stock.

Essentially you are trying to deal with xml that have varying errors of scaling and description.
There are likely to be others buried in your xml too.

So I flashed the v7 rom, copied the immobilizer, ignition and fuel tables, but the car wouldn't start, no check engine light, it would crank over but not start.

Disable immobilizer from periphery bits.
