GT1R MoTeC C127 Dash Replacement with Display Creator Option


The main screen includes dial gauges for Engine Speed and Boost Pressure, a digital gauge for Vehicle Speed and Cruise Control Set Speed, as well as bar gauges for Fuel Pressure, Oil Pressure, Coolant Pressure, Engine Oil Temperature, Gearbox Temperature, and Coolant Temperature. 


In addition to your gauges, you have indicator icons for low battery voltage, low oil pressure, high coolant temperature, airbag warning light, seatbelt warning light, light, parking brake engaged, left and right turn signals, high beams, check engine light, low fuel light, traction control off light (Motec TC, not the OE system), and 4WD light.


This is the airbag indicator.


And seatbelt indicator


The Gear Position indicator works just like a stock cluster, with P,R,N, 1A-6A and 1M-6M indications.  In the event that the TCM is trying to engage 1st gear or Reverse and it can’t get in, the factory cluster will flash the gear as an indication.  This will do the same.


The Gear Position indicator will be overridden with an indicator showing which door is open, in the event one is open.


In the center top of the screen warnings will be displayed, these can be warnings programmed into the file by us (triggered based on the Warning Source in the M1), as well as alarms you can setup in Dash Manager.


The ‘Steering Wheel Switch’ in M1 is the up/down cruise button on the steering wheel, the position of this switch is indicated on the tach as ‘MAP – N’

When in Launch Mode, the background of the screen will turn green when RPM and Boost are up to target, indicating ‘ready to launch’.


When your FWD clutch is disabled (when the M1 is doing FWD control only), the warning will pop up in the center of the tach.  You have the option to toggle from the text indication to a video of a burnout from within Dash Manager.


When the TCM is doing a gear relearn or transmission check upon startup, the ‘Transmission Check’ will pop up on the main screen.


The dimming of the cluster is taken care of internally, we chose to control the brightness based on the headlight status rather than the dimmer buttons.  When using the dimmer buttons, it requires adjustment manually in day vs night, this way it automatically adjusts based on the headlight status.


The trip button works to toggle between the odometer and trip meter by pushing the button for more than .25 seconds.  If you hold the trip button for over 3 seconds it will reset the trip mileage.  The odometer is fed by the Odometer channel in the M1, see the M1 for instructions on how to reset to match your OE cluster, note mileage before removal if you’re concerned with the odometer on the C127 matching your OE cluster.


The two buttons on the right side work to toggle gauges and pages.  The top right will toggle between the boost gauge on the left and a speedometer.  If setup to do so in the M1, the cruise cancel button on the steering wheel will display ethanol content in place of the boost gauge while it’s being held.

The bottom button will toggle through the screens, the main screen, then the diagnostic screen, then the TPMS screen if it’s enabled. 


If you are not using TPMS sensors, you can disable the TPMS function from within Motec Dash Manger.  If you are using TPMS, this system works differently than stock in that we’ve allowed a user configurable pressure threshold for each tire, so if you’re using drag radials at low pressure, you can lower the threshold to prevent the TPMS light from coming on.  If the system reads a tire pressure below the threshold, it will light the TPMS icon on the tach on the main screen.  From there you can toggle to the TPMS screen to see the status of each tire.   If it’s below the threshold it will show outlined in red.  If it’s between the minimum and 55psi, it will show outlined in green.  If it’s over 55psi it will show outlined in orange.

The diagnostic screen has real time values of various sensors, and the outline will turn red if any of them are in fault, and the warning source will indicate what the problem is if there’s a fault.


When the fuel level gets below 25%, the bezel around the tach will turn orange, the low fuel icon will illuminate, and the alarm window at the top will notify you that the fuel level is low.


Within Dash Manger you can change multiple parameters:


  •  You can set your TPMS low thresholds
  • Disable the TPMS warnings (1 to disable)
  • Disable the green background launch indicator (1 to disable)
  • Disable the seatbelt indicator (1 to disable)
  • Disable the airbag indicator (1 to disable) 
  • Toggle from the RWD only (burnout mode) text indicator vs video (1 for video)
  • **Do not adjust GTR Constant 1.  
  • These are found under Calculations / Constants in Dash Manager.


Your alarms and shift lights can be setup as desired in Dash Manager.
