This seemed to work perfectly, only issue I have remaining is the revs jumping around from 1800-1000 rmp when slowing down and slow speed like going through the car park, also I get a bit of a dip in rpm when taking off from a stopped position.

Will do later today, using a cable throttle body. Not electric Do you mean for crusing speeds or deceleration

my throttle response is really sensitive on deceleration, specially from 2000rpm to 1200ish. I get that jerking sensation on light throttle when trying to depress the throttle lightly. also very sensitive on little throttle application around 2000/3000rpm, cruising speeds. 2JZGE-T NON VVTI , tune file attached. any help would be useful. I have re calibrated the TPS new ignition boost 1800 2.pclr

Perfect thanks, and I need to use a sensor ground, not just any ground?

Is it possible to use the same +5v power supply for 2 different sensors, as I only have 1 5v+ outlet on my supra link

Would I set it up through an DI, if it's just a 12v switch

Sorry I'm still abit confused, so you taken the signal wire going for the gearbox, wired that into a digital input. And then have a aux output going to the dash speedo? And the 12v supply to the gearbox was cut and used a 5v supply instead?

When you wired directly to the ecu is that to a DI ?

I have a supra link in my supra, 2jzge non turbo converted to turbo. My speedo is out because I have bigger tyres on the rear, I have a mechanical driven speedo sensor on the gearbox 3 wire, factory wiring. How do I wire the speedo sensor on the gearbox through the ecu to correct the dash?

It's a straight 6 3.0l turbo, any recommendations for Hz? When it's in ISC solenoid it doesn't seem to work

I have aux 4,5,6,7 shown in use for old settings the new adapter harness only uses pin 1 and 2 do I need all those aux set to IAC solenoid? And what frequency should i set it to as a starting point? Is higher frequency less or more adjustment ?

Hi, I've just installed 2 wire slytech IACV on my 2jz, previously had the factory 6 wire IACV. I have used a harness, that plugs into the factory IACV plug, when I look at the settings it only had 6 wire and 4 wire, I don't know what settings I need to used the 2 wire setup, If I change the duty cycle as it is in the 6 wire setup it reactes. 1% duty cycle open the valve too much, unsure of proper settings, do I need to use GP input?

I've been trying to adjust my cold start better with the iacv and opening the throttle body screw slightly, what is the best way to adjust the tune in relation to its getting slightly more air, lower revs? Supralink 4inch intake with factory iacc single turbo flex fuel is the setup

Just wondering how to setup a rev limiter on my supra link 2jz ge non vvti turbo setup, but I want it on a switch so I can turn it off. Is it possible?

All working, thanks for the help. I Will be able to get it tuned this week!!!

So that black wire at the bottom? I didn't realise the diagram was the connector unplugged (so the image is flipped) I'll try today

So from the ecu A16 to pin 29 going into the Orange plug ? I did try like this earlier didn't seem to work tho What settings are recommended to try changing in the ecu?

I have it wired to the pin in image above, but do I tap into the wire or cut and wire to one end? And if one end which 1? I thought a saw the garage twitch when I turned the key on

Is this the correct harness plug ? Or on the main connector

Okay cheers for info Thanks for the info

No, I haven't switched any wires around yet. Few different answers posted here, I don't really wanna pull the cluster out in worry if damaging anything else, so what exactly needs to be done Are you saying I need to do both? removing removing tacho garage and add a wire into AUX1, and splice into pin 29

Since I have wired my coil packs and no longer using distributor for ignition but only for cam/crank signal, I have no tacho, I've been ready about a relay is needed to up the current, how exactly do I wiring it up ? It is a supralink ecu, 2JZGE NON VVTI SUPRA JZA80 1995

Is it possible there's a short inside the ecu? I was going to rewire from aux 2 to another aux output and re try,

Also now the fuel pump continues after ignition is switched off for 3-4 seconds?
