VICS/VCTS/VTCS/VCT/VVT The East Coast Family
Hey,
I would like to get it right.
All NB:
VICS = Varible Intake control system
BP-4W
99-00
VTCS = Variable Tumble Control System
01-05 (VVT+VTCS)
VCT = VVT = Variable Valve Timing
BP-Z3
01-05 (VVT+VTCS)

99-00 VICS
01-05 VVT + VTCS
this could be found on wikipedia.
although the way they describe VICS is incorrect.
I'm not sure what the 04-05 MSM came with, I don't believe those had VVT, but they still had the VTCS IM.
If you own a 01-05, you should make the efforts in fitting a 99-00 VICS IM.

VICS = NB1, butterflies sandwiched between the two pieces of the manifold
VTCS = NB2, butterflies at the intake runner that mate to the motor
There's another OE intake, but it was EU and Japanese domestic markets only; referred to as EUDM/JDM Squaretops.
For relative performance, here's how they stack up:
VICS = best all around intake, makes decent amount of torque
VTCS = used for emissions purposes, no real performance to speak of
Squaretop = higher peak HP at the expense of mid-range torque

base map is wrong ?
DPO17 is configured for "Dual intake valve"
On its settings you configure:
On value:
Off Value:
Pre configured to 5250rpm on, 5150 off
On the 01-05 base maps I find only VCT on DPO17 and no VTCS output...
What do you make of it ?
Even MS control VTCS... weird...

I don't understand what you're trying to figure out. Tune your car.

FTFY.
The real difference is in the dyno graphs. I tuned a VVT with VTCS intake manifold that consistently had 5 extra hp and 5 extra ft/lbs than another VVT engine with a VICS manifold. But the VTCS started dropping off at 6200rpm, and the VICS engine pulled out a 8hp and 6ft/lb lead by 7000rpm.
I'll post the graph soon.

I got a spare, free VTCS manifold for my 01. I've seen 100 different threads say 100 different things, so i figure whats one more in deciding if its worth porting, or just holding out for a VICS / square top. The car is a street car now, so i like having the torque, but it'll be a full time track rat come fall.
