Trim % calculation


Recommended Posts

Does the individual cyl fuel trim calculation act as a straight % change to the final calculated fuel amount to be delivered.

Have recently moved from autronic to link, and I am finding that the link seems to need much larger trim values than the autronic on the same engine.

Correct, it is an overall multiplier to the calculated effective pulse width.  So 5% in the table would mean that cylinder receives 5% more fuel than the others.  Have you checked injectors are wired correct so it is adjusting the correct cylinders?
