Title: FUEL TRIMS
Post by: Scoobykiller on September 30, 2016, 08:45:36 pm

So today i found out about fuel trims.
So decided to check mine
The results are -1.9 +17.2
What does this mean is it bad?
Thanks

Far from ideal really. Substantial under reading from the MAF sensor caused by the intake. What map? Standard?
