How do you reset the computer on a 09 mazda bt50
Today's ECU's have some pretty awesome abilities.
Many years ago before computers controlled cars, you had literally heaps
and heaps of adjustable areas under the engine to get the engine tuned
and running sweet, set the fuel mixtures, timing, clearnes for BTDC,
These days the engine has sensors all through the engine to see what is
happening and report back to the computer, and based on this information
the computer responds with instructions to control the engine and keep
it running how it 'believes' it should run based on the information
received from the calibrated snesors located in the system.
There are several key-sensors in the system that the ECU learns from, including crank angle sensor, o2 sensor, and knock sensor.
After a while, the calibration of the sensors becomes scewed slightly from wear, from pollution and dirt, etc.
Performing an ECU reset usually means that the computer goes back to
factory rom settings, which are fail-safe levels, and then it quickly
learns from the readings it gets back, comparisons to what it thinks it
should see and what it really is seeing, then it adjusts and re-compares
On most cars and ECU reset will se increased fuel consumption for the
first 15 - 30km's, but then levels back to normal, and on some cars you
can get better consumption after the level off period.
After my speal above... take the negative lead off the battrey for 30mins
