[3uzfe e throttle]

I'm happy that i have the main and sub the correct way. I have VPA(main) going to analog volt 1 and set as TP main and VPA2 (sub) going to analog volt 5 and set as TP sub. Do you have any settings for 3uzfe or lexus / toyota throttle position that i can use to try out? I was reading in the help tab that most toyota / lexus TPS are "non linear" and the TP Sub number must be set to the TP main % that the sub number stops increasing at (typically around 60-70%. When it refers to sub number, is this the voltage in the TPS tab that i have to alter?

Thanks

The 3URFE looks the same to me (albeit the pinout is different). I shall double check my sub and main wiring tomorrow but i'm 99% sure i have VTA as main and VTA2 as sub. This is my diagram i've been using

Thanks for your help Adam

I should have posted a shot of my pids aswell, i shall do that first thing tomorrow. As far as i know it doesn't have a clutch, no mention of it in my wiring diagrams and all 6 pins are populated and correct. When it calibrates the individual main and sub it passes them fine and i can physically see them go from 0% to 100% and 0.2ish volts up to 4.9ish, but i guess the main vs sub calibration compares the 2 and maybe there is some different between my main and sub PIDs, and if i watch the main vs sub calibration take place i can physically see that the main isn't going to as higher percentage as sub

Good evening guys! 

So i've correctly wired in my +14v aux9 and 10 circuit with a relay, all works fine now. I've calibrated my APS, although sub and main both follow each other from 0% to 100% when pedal depressed, is that normal?

As for TPS, i have error 16: cannot reach target 98%. If i watch the auto calibration take place, the main only hits around 3% whilst the sub goes right up to almost 5%, this is on the main vs sub calibration stage that this issue happens. I guess its due to a pid i need to change. Any advice?

Kind regards

That's brilliant thankyou! I should spend more time looking at that help file to help me fix some issues! 

I shall wire that in tonight and see how i get on!

Thanks for your responses guys. 

I've just rechecked my 3uzfe diagrams and found the etcs-i is powerd by a 10amp fuse. Because i'm quite new to this i presumed the that extreme ecu aux9 and aux10 would power the e throttle motor driver circuit. I think the reason i am getting low voltage is because i have no 12v supply into the ecu for these aux outputs. So my guess is i will have to add a 10amp ignition supplied fuse into my Link ecu specifically for the aux 9 and 10 to use. Is this correct? And if so what pin should i use in the link ecu?

Many thanks for your help

Hi there

I've finally got my 3uzfe running in my is200. I used the 1uz vvti basemap and it started first time after i set up my inputs and outputs.

I'm very new to tuning / ecus and link software so be gentle! Haha

I have a aux 9 and 10 supply error voltage lower than expected for my e throttle. I can see throttle position (11%) but obviously my throttle body isn't working. I understand there is alot of setting up / calibrating to do, but i'd like to get this done before i take the car for mapping. Does anyone have any tips / pointers on how i can set this up? My accelerator pedal works and is calibrated. Is this error due to wiring (which i know is 100% correct and even switched the wires around to test) or is it because a parameter / pid isn't set correctly and is flagging this fault up?

 

Many thanks

David
