Dash Channel Reference

The Rush SR factory AiM configuration defines a fixed set of channels. These are the canonical channel names for the MXS 1.x DBW config (Rush SR MXS v1.x DBW), as shipped in the AiM Config Releases. Use these names when setting up overlays, building custom dash pages in RaceStudio 3, or talking to support about a channel.

Note

Different configs (MXM, MXS v2, KLine) share most of these names but are not guaranteed identical. If a channel is missing in your config, check the AiM Config Downloads section and flash the matching .zconf2.

Analog Inputs (A/D Channels)

Analog channels are named Ch01 through Ch08 on the dash. The physical input wired to each is fixed by the factory harness.

Channel	Name	What it is
Ch01	Oil_Pressure	Oil pressure (VDO sender)
Ch02	Front_Brake_P	Front brake pressure
Ch03	Rear_Brake_P	Rear brake pressure
Ch04	Fuel_Level_6galT	Fuel level (6-gal tank sender). Set up manually if you have the 12-gal tank — see Installing a Fuel Level Sender.
Ch05	Channel05	Spare analog input
Ch06	Channel06	Spare analog input
Ch07	Channel07	Spare analog input
Ch08	Channel08	Spare analog input

Note

On the stock config, Ch02/Ch03 read pressure transducers and are named Front_Brake_P / Rear_Brake_P. The physical AiM device definition still calls the input Front_Brake_V / Rear_Brake_V (the raw voltage); the config relabels it to pressure. If a data log shows _V, that’s the raw voltage channel — the _P channels are what the dash uses.

Analog inputs on a car with the GCU Mk3

On an MXS 1.x dash with the GCU Mk3, the config built for that car uses a different order. The front brake pressure comes from the GCU over CAN, so it is not on an analog input.

Channel	What it is
Ch01	Oil pressure (Rush 150 psi pressure sensor)
Ch02	Rear brake pressure (Rush 1000 psi pressure sensor)
Ch03	Fuel level (6 gal or 12 gal tank sender; leave unwired if the car has no sender)
Ch04	Fuel pressure (Rush 150 psi pressure sensor)

Rewire an older car to match before you load that config. See Check Ch01 to Ch04 before you update on the GCU Gen 3 page.

Math Channels

These are calculated on the dash from the channels above. Two of them have near-identical names for different jobs — watch the suffix:

• Oil_Change_Neede / Motor_Rebuild_Ne — the maintenance hour counters (reset via Usr 3 / Usr 4)
• Oil_Change_Needed / Motor_Rebuild_Needed — the status flags that light the dash icons

Name	What it is
Front_Brake_P / Rear_Brake_P math	Brake pressure correction (voltage → PSI)
Brake_Bias	Front/rear brake bias
BrakePerc	Brake percentage
Brakes_On	Brakes applied (threshold)
Low_Oil_Pressure	Oil pressure low threshold
High_OilP / Very_High_OilP	Oil pressure high thresholds
High_CLT / Very_High_CLT	Coolant temp high thresholds
Oil_Pressure_Warning	Combined oil pressure warning
Water_Temp_Warning	Coolant temp warning
Oil_Change_Neede / Oil_Change_Needed	Oil change counter / flag
Motor_Rebuild_Ne / Motor_Rebuild_Needed	Motor rebuild counter / flag
OilP_RPM_Ratio	Oil pressure vs RPM ratio — see Oil System Health alarms
OilPMult	Oil pressure scaled by 333333 — the numerator of OilP_RPM_Ratio
isDBWCar	DBW car flag
isOilUnderfilled	Oil underfilled flag
checkOilPump / lowOilP / Low_OilP	Oil pump / low oil pressure flags

Check_ClutchSw	Clutch switch check flag
oilPSenderFailed / OilP_Sender_Fail	Oil pressure sender failure flag
StartRec	Start recording flag
POTotCrntAll	Current draw total

What’s Not a Channel

Some dash behavior is configured elsewhere and won’t appear in the channel list:

• Alarms are defined in RaceStudio 3 under the dash’s alarm configuration — see Dash Alarms
• User counters (Usr 3 oil-change, Usr 4 motor-rebuild) are the maintenance-interval odometers, reset from the dash display
• Shift lights and triggered outputs are separate dash settings, not channels
