Rescaling the MAF is the thing - stock one maxes out surprisingly 'early'... Also hotwire MAFs dont like much more than 400bhp for a long time - the wire can be ripped off... hence my desire for a more sturdy hot film MAF that has higher dynamic range.

Rescaling and there is no linearisation map.

MAP sensor and throttle angle is OK on some systems, but Motronic is designed for air mass measurement.Paul Nugent

Except if you rewrite the rom ...
A guy in germany ( on opel vectra ) have rewrite ALL the rom of his vectra ...
Stock ecu with launch control , flat shift , MAP/alphaN and aquamist , what else ?
I'm not a big fan of maf , 1st because it's not " durable " , and 2nd because it's a restrictive part (
)
And 3rd ( lol ) , because you can't put a non-recirculating BOV without a " Popoooop " when you shift
