LATENT SOLUTIONS SUPRASTICK INSTALLATION INFORMATION

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

Tip:

Wire 6 & 7 not required, neither 18 & 19 unless running NOS or spray-bar and 16 is optional for Change-up LED.

Flappy-Paddle options. http://www.mkivsupra.net/vbb/group.php?discussionid=144&do=discuss

Tip:

When using OE Lexus Flappy-Paddles, use these (mono-directional) ground switching circuits to trigger relays for 12v SupraStick manualised gear-change feeds.

Flappy-Paddles to wires 10 upshift & 17 downshift.

Tip:

For Supra installation, using the above interface relay system, the redundant Manu button can be linked to wire 2, Auto/Manual switching and the O.D. button linked to wire 20, Shift-Table selection.

Which provides OE switch-function & dash-information display-lights for Manual/Auto & Race/Eco shift-options.

Via clock-spring - Change-up LED in hub

Solenoid no. 1. loom-wire is cut and bridged with wires 4 & 13, solenoid no. 2. loom-wire is cut and bridged with wires 5 & 14, lock-solenoid loom-wire is cut and transmission-tail connected to wire 15.

Wire no. 8. can be piggy-backed onto transmission speed-sensor (16ish-blips per wheel-rev) or alternatively, if you have, for a better signal link to an ABS sensor? (96-blips per wheel-rev)

That only leaves wire 3. to Ignition +, wire 1. to Ground - and three little piggies to back onto ECU loom-wires.

Wire no. 9, TPS. Wire no. 11, RPM. Wire no. 12, Brake Signal.

Tip:

2JZ-GE: Crank sensor = 12

2JZ-GTE: Crank sensor = 12

2JZ-GTE VVTi: Cam sensor = 3

1JZ-GTE: Crank sensor = 12

1JZ-GTE VVTi: Cam sensor = 3

1UZ-FE: Crank sensor = 12

1UZ-FE VVTi: Cam sensor = 2

Tips:

The only loom cuts are the 3 solenoid wires, all other joints are piggybacked.

Vehicle tyre size = Diameter in inches?

Now you're Flappy-Paddling.

SupraStick Compatible Software & I.T. Tips Delboy52

SupraStick was designed when Window 98 was about and interfaced using Hyper Terminal software and a serial port. To communicate with SupraStick using modern hardware and software and USB to serial lead will be needed.

An alternative to Hyper Terminal is a program called PuTTY.

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

A little configuration of the COM port will be needed (mine happens to be COM5 but it can be any available port). The best settings are:

- Baud rate: 19200

- Flow control: None

- Default everything else

When PuTTY is installed, set a few serial settings to match that of your COM port.

Update the serial port section.

This is what SupraStick configuration with Terminal software connected via the diagnostic serial connection looks like and what settings are available.

Thank you Mike.

(Please note: Vehicle Settings shown in Mike's pic and again below, are for 1UZ-FE VVT-i with; cam-sensor rpm signal - 3.769 diff - 18" wheels - 265 35 tyres - ABS speed-signal.)

Settings for 1J & 2J non VVT-i install using crank-sensor & transmission no. 2 speed-sensor.

1. = 12. (Crank-sensor)

2. = 4. (Transmission no. 2 speed-sensor)

3. = 41 or 38? Diff ratio. http://mkiv.supras.org.nz/specs.htm

4. = Diameter of tyre. https://tiresize.com/tyre-size-calculator/

5. = 2800. (Baseline - can be adjusted to suit)

6. = Bespoke. (How-To explained in PDF)

7. = Bespoke. (How-To explained in PDF)

jagman, reports that he also prefers puTTy to Hyperterminal. and has provided pics with a few words of his Soarer 1JZA80-GTE Installation.

Before

Showing the rear of the clock-spring - note 6 tracks - but only 4 used on soarer - these are cut (3) and used to provide up /down/ and earth , new wires fed to here from supra stick , and the old cut wires are used for the cruise control buttons. The 4th wire is for the horn and remains untouched.

This many wires

Note two relays used for paddles - centre of pic between syvecs and stick - note fused supply in centre below syvecs - relays /switches/stick/ all fused separately - suprastick has no fused supply supplied.

Eventually it all fits here

Display /audio buttons and cruise switch all do nothing - but could be utilised later with a better (more tracks clock-spring)

Thank you Adam.

Supra 1UZ-FE Hybrid Install by J_Meiser. (Confirmed "soon")

Supra 2JZ-GTE A340E Install by acandales001. (Update requested 19/05/17)

Mapping Suprastick has always been a PITA because the software kept dropping out every few minutes.

The problem would appear to be that Suprastick doesn't like serial to USB adaptors.

I have now bought an old Windows 98 laptop with a serial port and used this to map Delboy52 Mike's Suprasticked Supra with no issues whatsoever, if anyone needs it, just ask.

The too many and cack-handed gear-changes are so that you can see what I am doing and when I am doing it.

Excuse the awful racket from my supercharger.

Video demos of Surastick function

I'll have a full write up soon, but to map my SupraStick, I used a Dell Latitude E7450 laptop running Windows 10 Pro 64-bit, a USB-Serial cable and PuTTY - it's yet to let me down .

Here's a set of gear-change tables I mapped for the Hybrid in Delboy52 's 1UZFE VVT-i - A02B 3.769 diff - 18" wheels - 265 35 tyres.
