Does having a factory ECU (Aristo, IS300 etc) serve any benefit for controlling VVT-i or only if its tuned with a standalone? I'm sure actually tuning it would use the VVT-i to its full potential but I'm wondering what benefits there are compared from a factory VVT-i tune to a non-VVT-i.

I'm looking for the toyota emblem for the vvti valve cover. Anyone know if it's the same as the non vvti? Bonus points if you have the part number. Not sure if you can buy this separate.

Technically, could you run a GTE non-vvti ecu with a vvti head? Of course vvti will be disabled, but couldn't you just run it that way like a non vvti until you get to a tuner? Since it's disabled there is no way for the gear to retard/advance.

No. The motors have completely different trigger patterns. 12 tooth vs 36-2.

So I know this thread hasn't been talked on for a few months, but does anybody have access to the vacuum diagram for the GTE VVT-i? I am tearing my hair out trying to find it and am confused on the large port on the back of the upper intake.

I took this picture from a google search. The one in the lower right of the picture just below the brake booster banjo that still has a cut section of hose attached to it. toyota_2jz_vvti_30_twin_turbo_supra.jpg

Question,

For the guys who have swapped in their non VVTi TB and Intake manifold to these heads, does the factory TRAC casting/motor on the non VVTi TB interfere with the oil feed banjo area?

A digital crank sensor will not work with the vvti crank trigger. The teeth are too small and too frequent for the sensor to pick up.

I'm about to swap in a vvti motor to my supra that currently has a non vvti gte. Ms3x ecu single turbo e85. Is it possible to drop the vvti motor in and not have the oil control valve connected until I can get the car to my tuner? Will it run fine like that? From what I understand it will be at 0 degrees at all times
