MK4 Supra ECU

Recommended Posts

Hi 

Car: Toyota

Model: Supra (JZA80)

Engine: 2JZGTE 6MTM (JDM)

Since installing the 264 cams I am having issues with cold start (Closed loop), I need to fettle the throttle till she warms up ( she runs rich till warmed up); once she runs Open loop she runs fine

I read a few threads but they are all from 2015 , so far I am leaning towards the Fury but I know the Thunder is out now; what do you recommend? 

Based on my reading here I can use alot of the OEM sensors but what else do I need?, 

The stock knock sensors, water temp sensor, Crank/Cam triggers all work with the link.  The stock oil pressure switch is a bit useless, better off replacing it with a 150psi TI pressure sensor , the stock Toyota air temp sensor in the plenum with a faster acting sensor, the Fury uses the Bosch LSU 4.9 sensor and loom-side plug/pin kit

OEM Map sensor work?

I will need to run the Turbos in Parallel as opposed to sequential 

Essentials I want 

  • Engine Protection :Oil pressure, knock 
  • Wideband Functionality
  • Boost controlled via the ECU
  • Flexi-fuel compatible 

 

BPU(basic performance upgrades)   

•        JSPEC Turbos (Ceramic)

•        Apexi AVCR (1.2 BAR set)

•        First decat and Sard 2nd sport CAT(3 inch piping)

•        Greddy intercooler 4"

•        Tomei 264 Poncams

•        Denso IK22 (Colder grade spark plug for increated boost pressure)

•        Walbro 255 Fuel pump

•        HKS Silent Hi Power Exhaust

•        OsGiken Street master Clutch (Rated Approximately 575 ft lbs)

Hi,

Assuming your 2JZ-GTE is non-VVT?

You have a good grasp of what is required. The factory sensors, including the MAP sensor, will work with the ECU, you can upgrade to other sensors if you want to.

The best ECU options are the Supra plug-in ECU or the Fury. The Xtreme offers no advantage over the Fury on your engine, and the Thunder will do the job well, but is overkill.

Both the plug-in ECU and the Fury:

  • Allow a general purpose limit table to setup based upon oil pressure
  • Have knock control onboard.
  • Have boost control onboard
  • Have the Modelled - Multifuel mode which does a great job with petrol/ethanol blended fuels.

You are going to need to add an ethanol content sensor.

Does Link have a 2jzgte Non-VVTI base map for the Link Fury ?

The Supra plug-in base-map can be loaded into the Fury. You will need to adjust the AN Volt, AN Temp, Digital Input, and Aux Output channels to suit.

Thanks Scott ! Yes she is a non-VVTI 

Out of curiosity looking at prices on dealers websites , considering the PNP kits from what I gather are based on the Extreme ECU , they need an  add-on 02 Module to run wideband sensor , the Fury has a built in O2 Wideband controller 

Whys is the PNP KIt with O2 Module more expensive then the Fury even though the Fury is higher spec? Has DBW (Which I dont need but you can get DBW kits for Non-VVTI now)

Hi Scott

I am confused on temp sensor , I cannot see a 3/8 listed on the link website but the 2JZ PNP says it uses a 3/8 NPT
- Bosch push in

What wideband controller options are there with the PNP kit 

Innovate LC2 or the MTX-L?

Mainly due to the time involved in the development of the unit for the specific application, (working out pinout, making board fit factory case etc)

Any temp sensor can be used but if you stick to the ones we offer the set up is easier. The Bosch sensor is the best but not so easy to mount.

Any wideband controller with a 0-5V out put can be used.

Hi Simon

 I am looking through the engine protection strategies on the ecu tuning function online help and I don't see anything mentioned about knock , setting thresholds for oil, fuel pressure to trigger a limp home mode ; is it possible in the pnp kit

Is the quick fuel tuning VE tuning?

Does traction control work on the Supra model or would I need a digital signal from the ABS sensors to measure Wheel Speed/slip?

What is the difference between Can Port and RS232 I see on other models ?

Hi Jellybean,

Knock control can be setup to detect (and log) only, or to retard ignition timing when required. This is accessed through ECU Settings > Knock Control. The GP RPM Limit table axis are adjustable, so you can put oil pressure, fuel pressure, etc on these tables, and then control the allowed engine speed to make a limp home level. This is possible on the plug in ECUs provided they have the required input data.

'Quick Trim' (M key when on fuel table) is used to quickly get PCLink to make a change to the fuel table based upon the data you enter. 'Quick Tune' is a tool for helping you live tune the fuel table, it is more comprehensive than the Quick Trim.

The traction control needs  a driven and non-driven wheel speed source. On the Supra this will need to come in the ECUs digital inputs as the Supra never shared info over CAN as far as I'm aware. Beware that the maximum frequency the Digital Input channels can accept is 500 Hz, it your ABs trigger wheel has two many teeth you could exceed this.

Some plug-in ECUs have two CAN bus modules, others only have one. The RS232 (Serial) is able to be used for communication with older dashes and also for tuning the ECU from a PC's serial port.

The knock control will try to remove timing if set up but there are no limits around it to actually limit the engine.

Quick tune is tuning tool and as such I guess you could say it is VE tuning as you are tuning to suit the VE of the engine.

Traction control on the Supra would need additional wheel speed inputs wired in. The frequency off the ABS sensor will be too high for the Di inputs. You need inputs will a lower tooth count to keep the frequency under 500Hz

No difference. On all models the port has both can and RS232 in it. It just depends on which wires you end up using.

Thanks Simon!

Will  the plug and play ecus run the injectors sequentially and the coils on pre VVTI engines sequentially?

Will the knock control strategy alter timing on a cylinder to cylinder basis?
