1JZGTE VVTI 36/3 to 36/1

[joooeone]

hello every buddy the name is joooe one and i have a 1992 cressida with a 1jzgte vvti on it i bougth the ms3 and ms3x and some one on diyautotune told me that 36/3 is not ssuported that u should cut 2 out of 3 tooths on the camshaft so that the ms3 can read the tooth is that the only option that i got?

How does this compare to the 2JZ VVTi that is available in the development beta code?

what I know theres no comparison the 2jz doest use wasted spark and the 1jzgte vvti does the only engine that I can think about that is kinda similar is from a is 300 lexus the 2jzge vvti

[jsmcortina]

Don't worry about the output too much. Are the wheel patterns and phasing the same?

James

[joooeone]

from the.2jzge vvti yes its 36 with 2missing tooths and 3 tooths on the cam shaft

[jsmcortina]

Worth trying that wheel mode in the latest beta code. (See the MS3 development forum.)

James

[joooeone]

yes I will thnx james

[joooeone]

is this code that you were.talking about the 1.1 code?

Glad I found this thread. Joe - are you in the states? I'm in NY and planning on doing a JZ series swap (possibly VVT-i) and it would be good to have a friend to bounce ideas off of. I don't want to hijack your thread but it seemed like a good place to put this info WRT megasquirt and VVT-i control.

Here is some info on VVT-i and standalone management systems, the first link has a lot of great info:

http://www.mr2.com/forums/beams-owners- ... beams.html

Conclusion is that VVT-i can be controlled with a state switch (on/off) instead of continuously variable, however this is far inferior to continuous control, which the stock ECU offers and is based upon a function of many engine input variables and is not 100% intuitive as it serves to enhance torque and not high end power.

Is anybody currently CONTINUOUSLY controlling their VVT-i setups? If so, how did they arrive at their mapping strategies and hardware setup?
