Sorry for using the work "kick in"...maybe it is more suitable for those Turbo car ba..
What I mean is when the IAFM started to work or something GREAT happen to the engine, I can notice a the RPM accelerate faster.
For example I am going around 50km/h which RPM around 2.2k like that. While the RPM going up slowly suddenly I feel the engine sound like "kick in" and the RPM go higher constantly in a faster pace and the car will feel more acceleration than normal (while doing 50km/h). Is this acceleration feel caused by the IAFM ? bcz I can be sure something happened in the range of 2.2k - 3.2k RPM which causes the car to be more LIVELY. Maybe no kick in effect la but I am sure it must be due to the IAFM.
Anyway to not pro-long this "kick-in effect" right or wrong or maybe it is just my imagination afterall
, I just want to say it is nice to have driven Saga FL and forget about FC hahaha.
Thanks guys for prodiving useful information to me
cheers and Happy Friday!!!!
As you move up the RPM range you wil accelerate faster and faster because the engine is generating more and more torque, until you reach 4k RPM when the torque will decrease after that.
Just refer to the torque curve in the pdf document I posted about the IAFM.

This is interesting, I always thought IAFM changes intake length just for torque dip zone.
Anyway, some technical research paper for the interested:
http://ejum.fsktm.um.edu.my/article/686.pdfYou are right that the IAFM and VIM was developed to fix the torque dip, just not as directly as you thought
CFE skipped the whole variable intake manifold shebang by using VVT.
