Toucan Touchscreen Display

Be the first to review this product


Toucan touchscreen display unit.

Toucan is an innovative touchscreen display unit that connects, via CAN bus, to the Syvecs or AlcaTek (originally Simtek) engine management system.

It has 2 main functions:

  1. Easy naming and selection of Calibrations (or maps), in place of the standard rotary switch.
  2. Extensive gauge displays, complete with audible and visible alarms, as well as absolute and dynamic peak markers.

Each CAL position is provided with 3 lines of user-entered text, minimising the risk of selecting the wrong map. PIN protection can be enabled, so the vehicle may be parked with an immobiliser CAL enabled (with no fuel injected, for example) or a valet mode (with low rpm limits), with a PIN entry required before the CAL can be changed.

Gauges have a absolute peak marker (with reset button), plus a dynamic peak marker that holds the most recent peak for a configurable period of time before dropping back to the current value.

Four main gauge pages are provided, each with a conveniently grouped set of gauges. A quick touch on any small gauge causes a full-screen gauge to be displayed and the unit can also be set to immediately show the relevant large gauge when an alarm is triggered.

Alarms can be individually enabled for each parameter, with the alarm thresholds set as required. A low oil temperature warning can be enabled, especially important for turbocharged engines to avoid driving hard when the oil's too cold. The audible alarm may be muted if wished.

When used with an AlcaTek ecu, launch control and antilag can be turned on and off directly from the touchscreen, and the launch RPM can also be adjusted from the screen.

The display is a full-colour TFT LCD with 320×240 pixels and a resistive touchscreen. Backlight dimming for night time use can be manually selected, and/or automatically enabled if the unit is wired to the vehicles “illumination” circuit.

Two (or more) units can be daisy-chained together allowing different gauges to be displayed simultaneously, and since each will remember its current display at power-down, the displays will be as you want them next time you start the vehicle.

Green, red and white colour schemes are provided to suit most vehicle dashboards.

Gauges and Alarms

Gauge scales can be display in either imperial or metric units, and road speed in mph or kph. Alarms can be enabled individually as required for each parameter.

Of course, gauges will only show valid data when appropriate sensors are wired to the ECU but gauges 1 through 9 below are generally available for most installations. Only full screen gauges for available sensors need be enabled, meaning “dead” gauges are not displayed.

1. Manifold Absolute Pressure 0-3.5bar
2. Boost 2.5bar
3. Air Charge Temperature 10-70C/50-150F
4. Coolant Temperature 60-120C/80-280F
5. Battery Volts 11-17V
6. Current Gear As determined by the ecu
7. RPM 0-10,000rpm
8. Wheel Speed 0-200 mph/0-300kph
9. Throttle Position 0-100%
10. Fuel Pressure (with selectable differential mode) 0-10 bar
11. Exhaust Gas Temperature 200-1200C/300-2300F
12. Lambda

Narrowband mode (Lean/Rich indication)

Wideband (0.7-1.3?)

13. Oil Pressure 0-10bar/0-150psi
14. Oil Temperature 50-150C/110-290F

Additionally, a warnings are provided when engine knock is detected by the ecu, if injector duty cycle exceeds a selectable value, or if a sensor connected to the ecu fails.

Wiring and Installation

Toucan is intended for permanent or semi-permanent installation. It uses the Herbert Richter™ 4-prong mounting system and is supplied as standard with a permanent-fixing swivel mount. Vent clip or windscreen sucker mounts are available as options.

A single latching connector on the rear of the unit attaches to the supplied cable harness, allowing occasional removal of the unit if required. The harness provides connections to vehicle power, the Syvecs ecu itself, and for the CAL switch wiring.

Accessories are available to simplify installation.
