snapey:
Any timeline for when you'll be having the rods and pistons dropped in?

Poppa Dom:
MAP - Manifold Absolute Pressure, map sensor readings are used to calculate air density which in turn calculates air flow and is then used to regulate fuelling.

its the sensor in the TB pipe from IC to TB.

ECU is clever u see...uses MAF to read airflow pre turbo...then MAP to check again before Intake Manifold...then uses Lambda probe to check mixture on exit!

If all is good..u get the full beans. If its bit off..u get limp mode!   :grin:

Janner_Sy:
cheers to DOMT and chungster. might look into the same as well then

Sort of. You can run with the MAF disconnected and still get 'the beans'.  :wink:
