MAF relocation accomplished:
I did the relocation and have driven the car now for about a week, so I am convinced that the improvement is not a figment of my imagination.
The acceleration is much smoother now and when driving slowly the car does not jerk back and forth. All in all, I would say the improvement is definitely worth the time and small expense.
As an aside, I wondered why there is an improvement, since the only difference is the volume of air in the tube between the MAF and the butterfly valve.
After a little thought, I have the opinion that the volume of air introduces a resonance effect that fools the MAF into thinking there is more or less air flowing into the engine. This could account for the "bumpy" acceleration experienced before the mod. Why it fixes the jerking is not clear to me.
I wonder if anyone has any knowledge on the subject?
