Shift-P2/P2+ Features Comparison
Warning System
When a warning is triggered (battery voltage, stall alert, channel 1, 2 or 3), the lights and display immediately show the warning and continue while the condition persists. The warning will stop if the condition for the warning is no longer met. For an analog channel input, this occurs when the voltage transitions past the off level.
If a button is pressed while a warning is being displayed, it is cancelled and will not automatically re-occur. A multi-function channel can be configured as an alternative cancel warning interface, where a push button should be used. If more than one warning is in effect, they will display using the priority order channel 1, 2, 3, engine stall and battery voltage alert. Using left/right, the display will normally cycle through RPM <> Battery <> Off, however if any cancelled warnings still meet their warning criteria, these will be shown while cycling these screens.
If a multi-function channel is linked to warning input channel, it’s output will be active while the warning is displayed. It will be inactive if the warning is cancelled or when configuring associated parameters.
The Shift-P2+ provides 3 auxiliary channels.
Each channel can be used as an input or output.
Each channel can be used as a low side output (open collector, up to 200mA) or as an analog voltage input. An internal 2.2kohm pull-up resistor can also be enabled.
The channels can be configured for a range of functions. For example: Use of an external buzzer for warnings and/or when shift point is reached. Switch input to dynamically change between user profiles. Tacho output to drive other devices. Stall alert output. Analog warning threshold input. This could be used to display a warning from a compatible sensor or another device (such as an external knock sensor unit). Light threshold output. Switch on an RPM threshold. Output switched in relation to another channels input voltage.
Some output functions provide options to pulse the output once, or pulse periodically. Trigger thresholds have adjustable on and off levels to provide switching hysteresis as well as to enable the logic to be inverted. Warnings are provided with a lights display and warning message on the display. These warnings can be cancelled using the front buttons or by configuring a channel as an cancel push button input.
Wiring & Compatibility
The Shift-P2 is designed to be compatible with a range of ignition systems.
Modern vehicles with coil-on-plug (including those with CAN Bus).
ECUs with a Tach Output. 5V & 12V square/pulse signals.
Coil packs switched on the negative, including wasted spark.
Works with many distributors (please ensure no excessive contact bounce with mechanical distributors).
Requires only 3 wires to be connected, RPM (blue), Switched 12V (Red), Ground (Black).
A further 3 wires are provided for Shift-P2+ additional functionality (see User Manual).
Green = Channel-1 White = Channel-2 Orange = Channel-3
Connection
The cable supplied uses high quality lightweight flexible wires. The flat connector is intended for permanent installation purposes only. It is not intended as a connector that is regularly disconnected and reconnected. The connector will only fit with the correct orientation as shown. If you need to disconnect the Shift-P2, switch the power off and push the locking tabs shown to release. Recommended method is to use a small flat blade screwdriver to release one tab at a time.
Micro-USB socket is also included for future firmware updates that may be made available.
FAQ’s
- How quick does the display register the RPM?
Very very quick! The RPM measurement algorithm does not use the basic pulse counting technique, or basic frequency to voltage converters. The RPM is digitally calculated per pulse! The digital filter algorithm is biased to displaying an increase of RPM quickly and accurately, while also filtering any electrical noise. The exact time is quite dependent on the frequency of the tacho signal. This level of precision and speed is what makes them an ideal visual reference for drag and motorsport racing. The Shift-P2 is likely more accurate and faster than most tacho gauges.
- How bright are the lights?
Each light actually has TWO LEDs. They are quite bright and can be viewed from a wide angle! Even with full sun shining on them, you can still see them clearly. They were designed to be bright enough for use on motorbikes, with a wide viewing angle. The in-built light sensor however does a fantastic job of reducing the brightness when the ambient light drops off, which is adjustable.
- Can I have them Flash at just the Shift Point?
Yes! One of the provided display modes will flash all the lights only when you exceed your set RPM point, just like a traditional shift light. Or you can program a specific display sequence with the Shift-P2+ model.
- Can I Turn the display off?
Yes! Use left or right to cycle the display to “Off” temporarily. If you are driving your mother-in-law around and need to keep the engine roar down, you can set the lights to default to the “Off” mode at ignition on. If however your passenger won’t stop talking, press a button and the lights will again let you know where the shift point is. Warnings are still active when the lights are set to off.
- How do I customising the lights display?
The Shift-P2+ model provides the feature to customise the lights display.
You have up to 15 Stages (16 including the first with all lights are off).
You don’t have to use all 15. You can use 5 if you want.
The RPM is equal between all the stages, however you can always (for example) make two consecutive stages identical. That will give a wider gap between lights changing.
The little arrow starts on the stage number. That is the stage you are adjusting. Up/Down to go to the next/previous stage.
Move the arrow to the right once. If you press Up, you toggle this stage between flashing and not flashing. Press down and you turn the stage off, making this stage and all higher ones not used. This is how to reduce the number of stages used.
Move the arrow to the right again and you are on the first light. Up/Down to change its colour (or turn off, no-colour).
Move the arrow to the other lights and change them too.
Take the arrow back to the left and change to the next stage… and customise this how you want.
Individual light colours available… red, green, blue, amber, yellow, cyan, olive, magenta, white, light green and pink.
Both a performance acrylic adhesive foam pad and adehesive backed Velcro (brand) for automotive use are included. These have excellent resistance to ageing, water, most solvents and UV light. They stick really well to plastic, but not to vinyl (particularly those with protective waxes applied). Alternative mounting plates may be available in the future.
- Can I mounts the lights external?
This is not possible. They are an internal component in a sophisticated electronics assembly.
- Is the Shift-P2 Waterproof?
It is not waterproof. The Shift-P2 must be mounted behind a windscreen, where it is not subjected to the wind pressure or rain. Ecliptech may make a waterproof variant in the future. Please contact us if interested.
The Shift-P2 has a 24 month warranty from date of purchase, return to base. This covers manufactured defects, not damage. If you ever have a problem with one of our products, please contact us!
