you're an idiot. don't buy shit before you know what the fuck it is. that being said, i don't have a pinout, but you can always figure most of the stuff out tracing shit or knowing what color wires toyota uses for certain things

[Jason]

...or by giving it to mark aphxero

[Bill]

what does it say on the throttle on the motor you got? etcs or etcs-i?

if it says etcs look for jzx100 wiring it'll probably be the closest thing

if it says etcs-i that is jzx110. good luck and god speed if you have that shit.

Haha drive by wire you suck!

Props on having it in there, though you probably will be pulling it to do seals

The dbw doesnt make it any harder at all to make it run. It just means your throttle response is going to suck, and you'll have electronic traction control, which you can turn off. Best thing for you to do is get a standard 1jz throttle body and an x100 eco. 6 wires and you're running

[Kyle]

You also need to see if those came with a ecu that has an immobilizer, because like avernier said you should be able to get it running, and assuming the clock is ticking on your warranty, that's in your best interest to hear it run

Also use toyodiy.com to cross reference the ecu part number in hopes it's close to jzx110 shit

[Bill]

does drive by wire have a separate control or throttle control that needs to be used to control the throttle tho austin? if the motor didn't come with that and it happened to be needed to run that would suck. i mean most motorsets are missing one item, like a maf or igniter, or a smashed something.

yeah, probably easier to buy a jzx100 etcs harness and ecu to get that going, but give it a shot if you think you can figure it out.

If it works the same as the 2jz vvti, the drive by wire is controlled by the ecu. The throttle cable is used to trigger the accelerator sensor and that sends the signal to the ecu then that sends a signal back for the correct throttle %. Pretty sure it's the same for all 1jz/2jz vvti, maybe not. Here's a video I found on it:

[Austin]

yeah, throttle linkage works as normal. but the cable only turns a sensor, wich acts like a potentiometer. the resulting value is sent to the ecu, which then sends a command to the throttle body, which has a constantly spinning motor, with a magnetic clutch engagement. the ecu tells the throttle body to close the clutch, which opens the throttle body. when it reaches the ecu's proposed value, the clutch repeatedly opens and closes to hold the position. then the vta2 sensor, sends back the confirmation to the ecu that the throttle plate is in the desired position, and the ecu goes along happily until the next change in throttle position.

[Austin]

oh shit. just watched that video which says almost exactly what i spent forever typing out.

[Kyle]

You're going to have to figure out which wires go to it. I know on the IS300 it's a type of switch that you have to hit everytime you get in the car. Prob be two wires that come from the ecu to a body plug of some sort. Have fun finding them.

[Bill]

my jzx100 vvti motorset actually came with a throttle ecu lol. it was a box about half the size of the ecu and was missing one big body plug. the harness plug went to the trac butterfly on the throttle body to control the movement.

that's why i'm asking if this might be the case for the jzx110 vvti 1jz.

There were 4 versions of Toyota's throttle control system:

Ver 1 found on JZX81-JZX90: "TRC" has a separate throttle plate for traction control, and a 4 channel ABS system with actuators to induce braking during wheel slip

Ver 2 found on JZX100: "ETCS" functions the same way as the TRC system, but now incorporates throttle smoothing. The traction throttle plate will help control air flow to reduce sudden acceleration.

Ver 3 found on JZX110 & JZS171; "ETCS-i" has a new throttle body with a hybrid drive-by-wire and direct control throttle plate. The secondary plate has been removed. The system still has a throttle cable and the cable will turn the plate 20% only, the remaining 80% is controlled by the servo motor (but the motor can control 100% of the movement if needed). This system allows Toyota to remove the sperate traction control throttle plate, the cruise control actuator, and the idle air control valve. This system has a even more agressive throttle smoothing algorithm that now controls decel along with accel.

Ver 4 found on gay-ass toyota cars and trucks: "ETCS-i" same system as Ver 3 but removes the throttle cable. This system is completely drive-by-wire by having a position sensor on the accelerator pedal and a 100% servo controlled throttle plate.
