Description

Your car on the screen. Not a car like yours.

Every digital gauge you can buy shows you a picture somebody else drew. A generic coupe, a generic needle, a badge that isn’t yours. You spent three years getting the stance right and the paint exactly that colour, and the dash still shows a silhouette off a shelf.

This one shows your car. You send us photos and we build the image set from those: the wheels you picked, the colour you mixed, the chop, the stripe, the hood you had made. Turn the key and your own car comes up.

It doesn’t care what you did to it. Bagged, chopped, shaved, LS-swapped, painted a colour that doesn’t have a name. That’s the point.

It knows who you are

It says your name out loud when you get in. Not a beep, not a logo: your name, in the language you picked. Five languages fit on the card and you switch between them in the menu, same as kilometres or miles. Every voice is included in every language you choose, so you can change your mind on a Sunday afternoon.

Because your name is spoken out loud, every line is recorded for you personally. Nothing is stitched together from syllables.

Or it says exactly what you want it to say

It comes with plenty of moments already written: getting in, everything checked and ready, time to fuel up, thanks for the drive, and the ones you hope never to hear, like oil pressure dropping or running hot.

Want your own words in it? €275 and you write extra lines of your own, as many as you like, and you say when each one should play. €375 and you rewrite the standard ones too, so every word it ever says is yours.

What it actually reads

On a GM LS or a Gen V LT it reads the CANbus signals straight off the OBD socket: revs, coolant temperature, gear position, check engine, oil pressure warning. No cutting into the harness. The fuel level comes from a sender in the tank, because GM doesn’t put that one on the bus and we would rather tell you that than pretend.

No bus in the car? Then everything comes from senders and switches. Same screen, same voice, same photos of your car. A carburettor and a points distributor is the simplest starting point there is.

Something else entirely — a boat, a tractor, a kit car? It runs on anything with 12 volts. Tell us what it goes in and we’ll work out where the numbers come from.

GM powertrain with a CAN pair on pins 6 and 14 of the OBD socket? Then it works.

  • The only test is whether there are pins in 6 and 14.
  • Pin 2 doesn’t matter. A 2005 Corvette has pin 2 and 6/14. Pin 2 only means there is also a Class 2 bus in the car, and that is very common.
  • It has to be GM. A Ford with pins 6 and 14 does have a bus, but with different message numbers.

Straight about what it is

It is 2.4 inches. It goes in a gauge hole or a pod, not across the whole dash. Kilometres or miles, °C or °F, language and voice: all of it is in the menu, so nothing is locked in on the day it ships.

Does this fit my car? Press the button above and you’ll know in two clicks. If we can’t tell you straight away, we say so and we look it up ourselves.

Availability: In testing

CTC Dash

2.4″ digital gauge display that shows your own car and says your name. Reads the CANbus signals of a GM LS or Gen V LT, or runs on its own senders in any car without a bus.

Two ways to feed it. On a GM LS or Gen V LT it reads the CANbus signals straight off the OBD socket — nothing cut into the harness. In a car with no bus at all it runs on its own senders and switches: same screen, same voice, same pictures of your own car. Carburettor and points is the simplest starting point there is.

Currently in testing

The CTC Dash is being tested in our own cars before it goes on sale. It will be available to order in a few months.

  • GM LS / LT1 Gen V
  • Stand alone — analog
  • Something else — boat, tractor, kit car, anything

The voice, the languages, the name and the pictures below work in anything with 12 volts. What we need to know from you is where the numbers come from. Fill it in below and we will look at it ourselves and get back to you.

What is it, and what should it show

  • Gen V LT — LT1, LT4, L83, L86
  • Gen IV LS — LS2, LS3, L92, LY6, L96
  • Gen IV LS2, early — 2005 to 2006
  • Gen III LS — LS1, LS6, LM7, LQ4
  • Automatic — 6L80, 6L90, 8L45, 8L90, 10L80, 10L90
  • Manual

Without a CAN bus there is no gear position to read. An older automatic can work, but it needs a gear position switch — that is a question for the intake, not a choice here.

  • Yes
  • No
  • Yes — a trip you can reset
  • No
Additional info — why a trip and no total mileage

The trip counts along with the speed and you reset it yourself. A few percent off is nobody's problem there.

A total mileage is only part of the complete CTC Customs system. It is the one part that affects the value of the car: replacing an odometer has to be registered with the RDW by a recognised company. The reading also has to be stored in two separate modules, which a single Dash does not have, and it is only right when tyre size and final drive are set correctly in the engine computer.

  • Yes — with range
  • No
Additional info — what this needs

A fuel sender of its own. On a GM the fuel level sits in a module that is not there after a swap, so that reading always comes from us.

Calibrated at the first fill-up, and that can only be done right once. Run the tank empty, then fill it in steps of 5 litres while we write down the value at each step. After that the screen knows what is in your tank — and only then is the range a real number instead of an estimate.

Is your original fuel gauge staying? Tell us. Two gauges cannot both draw current through the same sender, so it gets wired differently.

  • From the bus (warning light)
  • Own sender (reading in bar)
  • From the CANbus
  • GPS module
  • Pulse sender in the car

Revs, coolant temperature, oil pressure warning and check engine come from the CANbus. What you tick below does not come from the bus and gets its own wire.

Every signal comes out on 100 cm of wire, printed with what it is. You tie it into your existing loom: no plug to buy, no pin list to look up. Signals from the back of the car, like the fuel sender, need an extension and we supply those longer.

  • One input — a door is open
  • Per door — the screen says which one
Additional info — what per door means

In most original wiring looms all door switches are wired in parallel to one wire to the interior light. You then only know that a door is open.

Per door means work in the car: cut the wire at each switch, connect our wire, and fit a diode per door back to the original interior light wire — the band of the diode towards the door switch. The light keeps working, but one switch no longer pulls the others along. Without that diode the system thinks all doors are open as soon as one opens.

The diodes sit in the loom at the switch and not in the module, so the interior light keeps working if the module is taken out.

You can choose 5 languages. All 4 voices are included as standard in every language you choose, and you switch between them in the menu of the screen. With the play button you hear the standard messages. A sample with your name or your own messages is sent to you by email for approval first. Dimmed languages and voices are still being recorded.
