WRick- I know when you tried my AVCS map you commented on how spoolup increased by ~300 RPM and it leaned you out a bunch since you are putting more air through the motor. That is all good for torque/spool and bad for mileage

in a very simple explanation, with low port air velocity AVCS can help get more air into the cylinders. The AVCS operation can be broken into 4 basic areas

Vacuum Low RPM- Advanced AVCS causes EGR if there is enough oil pressure to advance
Vacuum High RPM- Not trying to make torque so I turn it off
Boost Low RPM- Low port velocity lots of AVCS increases torque and spoolup
Boost High RPM- High port velocity lots of AVCS not very useful, a little bit of AVCS can be helpful sometimes if you are not turbo limited

that was exactly what I had in mind. I don't give a crap's ass for MPG's, it's already ****ty. 5% better is still ****ty. I'll take the better spool up !

And yes, I'm spooling an td05-18g 21 PSI @ 31xx RPM's. on a 2.0L.

edit :

thanks for sharing btw !
