A9L is the 88-93 Mustang Manual ecu EEC4,
and the best one to have imho,
for tunability and acceptance to adaptive tune to engine modifications.
so your set there Merv.

Steve,
EEC5 starts to get a bit harder and once you get into Aussie Smartlock Ecus its sometimes best to retrofit the earlier Ecus ,as we have done in Ash Brights car.
Eb and ED pre smartlocks are essentially the same as their american cousins tho..

As far as your EEC5 AU Management it is very different,
running coilpacks,crank trigger and no distributor etc,wiring is different too,
in this instance your probably best to buy a full kit,
Retrofit then sell off all the Aussie specific stuff you dont need...

This will really depend on how good the Mass Flow Airmeter is calibrated to mimic the Ford factory original,

If they could guarantee their calibrations are the same as the AU meter I dont see why it couldnt work,

though the Ecu programming is far more complex in the later generation Ecus making them less forgiving,

even throttlebody airflow etc is taken into account in the programming which will be different with Massflo
