Glossário de Termos


Air temperature - The air temperature in the air box and intake system.

Air temperature sensor - Sensor located in the airbox to detect the temperature of the incoming air.

ATDC - After Top Dead Centre.

Barometric pressure -  Pressure of the air in the airbox. See MAP for difference.

Battery voltage -  The voltage at the input to the Electronic Control Module (ECM).

BTDC -  Before Top Dead Centre (TDC).

Calculated load - The actual volume of air per stroke flowing into the engine, expressed as a percentage
of maximum volume that can enter. Provides an indication of the percent engine capacity that is being used
(100 % = full throttle)

CAN - Controller Area Network (CAN Protocol is a method of communication between various electronic devices; Protocolo CAN é um método de comunicação entre vários dispositivos eletrônicos) 

Catalyst -  Device placed in the exhaust system which reduces exhaust emissions by stimulating secondary combustion of the exhaust gases.

Closed loop = lambda 1 = AFR 14,7:1 is the target value.

CTP Closed throttle position -  Throttle position at idle (i.e. against end stop), measured as a voltage and expressed as percentage.

Coolant temperature  -  The coolant temperature in the cylinder head.

Coolant temperature sensor  -  Sensor which detects coolant temperature.

Cooling fan status  -  The ‘on or ‘off’ condition of the cooling fan.

DOWNLOAD (tune) - Sending a revised map or data from the PC to the bike.   See also READ

DTC - Diagnostic Trouble Codes (Códigos de erro no diagnóstico) 

ECM - Engine Control Module (Módulo de Controle do Motor) 

ECU - Engine Control Unit (Unidade de Controle do Motor) 

Engine speed  -  The crankshaft revolutions per minute.

ETV = Electronic Throttle Valve

The ETV tables are only tables for the gear ratio of the throttle grip to the stepper motor that moves
the throttle valves (0-100%).

These tables are for the different driving modes (e.g. Rain, Tour and Race) for the ETV models e.g.
from Triumph, there are further tables for each selected driving mode, which operate depending on
the gear selected.

For the following description, the map of a Triumph Street Triple 765 was used as an example.
Stepper value 0 
in the ETV table = throttle valves closed.
Stepper value 1680
in the ETV table = throttle valves fully open (100%)
The stepper motor on this model has 1680 steps as a step to open the throttle valves 100%.
Means: 100/1680 = 0.058 .. - The stepper motor can vary the throttle position to approximately 0.06%

Special features regarding the ETV table-names of the Aprilia Shiver, Dorsoduro
and Caponord 1200 models

  • Map T = ETV-table mode touring
  • Map S = ETV-table mode sport
  • Map R = ETV-table mode rain

Special features regarding the ignition-table-names of the Aprilia Shiver, Dorsoduro
and Caponord 1200 models

  • I (T & S) = Ignition table mode Touring and Sport
  • I (R)        = Ignition table mode Rain.
EXBV - Exhaust Butterfly Valve (Válvula Borboleta do Escapamento) 

Freeze frame  -  A data set captured at the time a Diagnostic Trouble Code (DTC) is set.

IACV - Idle Air Control Valve/System
Stepper motor air valve controls amount of air to throttle inlet, to maintain idle or warm-up mixture when throttles are fully closed. System not used on latter bikes.

ISCV - Idle Stepper Control Valve (Válvula de controle do motor de passos de marcha lenta) 

Idle fuel trim - The percentage above or below the nominal fuel requirement for the volume of air entering at idle.

Idle fueling - Adjustment of fueling at idle to suit the actual air inducted.

Idle reference speed  -  The target idle speed as determined by the Electronic Control Module (ECM).
(It should be the same as the actual idle speed if the motorcycle is operating correctly.)

Ignition advance -  The timing of ignition at the spark plug relative to top dead centre.

Ignition switch position  -  The ‘on’ or ‘off’ position of either or both the ignition switch and the engine stop switch.

Ignition timing  -  Same as ‘ignition advance’.

Injector pulse time  -  The time during which an injector remains open (i.e. delivering fuel).

Long term fuel trim - Fueling after adapting to the engine’s long term fueling requirements (closed loop only). See also short term fuel trim.

MAP - Manifold Air Pressure (Pressão do ar no coletor de admissão) 

MAP sensor  -  Manifold absolute pressure (the air pressure in the intake system). Measured after the
throttle valves this reading is compared to the pressure reading in the air box (barometric pressure) to
allow the ECM to calculate engine load, 
on Keihin bikes (eg 675), the value can be used to adjust
throttle body sync
as there is one sensor for each intake. Earlier Sagem'd bikes (eg 595,955) do
not have individual intake sensors and require external device (eg Carbtune) to measure each intake.

MIL - Malfunction Indicator Lamp (Lâmpada indicadora de mau funcionamento)

Neutral switch status - The 'neutral' or 'in gear' status of the gearchange.

Off idle fuel trim -  The percentage above or below the nominal fuel requirement for the volume of air
entering at engine speeds other than idle. This function is not currently used in the Triumph system.

Open circuit -  A break in an electrical circuit - current cannot flow.

Over temp - High temperature within the Electronic Control Module (ECM) caused by an internal or external failure.

PCIII - Power Commander III (Protocolo de mapeamento de ECU) 

PCV - Power Commander V (Protocolo de mapeamento de ECU) 

Primary Throttle Position Sensor - Sensor for the primary (lower) throttle position.

Primary Throttle Stepper Motor (see also IACV) - Stepper motor used to vary throttle opening at idle
and when the engine is cold. (latter bikes only)

Purge valve duty cycle - The time the purge valve is open in an open / close cycle, expressed as a
percentage of the cycle time.

READ (tune) - Reading a tune or data FROM bike to PC. Bike ==> PC Road Speed Sensor - Gearbox mounted sensor which delivers information to the ECM that is
converted to the road speed value that is displayed on the speedometer.

SAI - Secondary Air Injection (Injeção de admissão de ar secundária) 

Sensor reference voltage - Supply voltage to the system sensors (nominally 5 volts).

Short Circuit - A 'short cut' in an electrical circuit - current by-passes the intended circuit (usually to earth).

Short term fuel trim - A correction applied to the fuel mixture during closed loop catalyst operation.
This, in turn has an effect on the long term fuel trim in that, if an engine constantly requires mixture correction,
the long term fuel trim will adapt to this requirement thus reducing the need for constant short term adjustment.

Sidestand status - The 'up' or 'down' position of the side stand.

Target dwell time - The actual time from coil 'on' to coil 'off'.

Throttle position (TP) - The position of the throttle butterfly given as a percentage of the movement range.
When the data is displayed on the tool, fully open need not be 100% nor fully closed 0%. Read by the TPS (sensor).

Throttle voltage - Voltage at the throttle potentiometer.

TC - Traction Control (Controle de tração) 

TPMS - Tire Pressure Monitor System (Sistema de monitoração da pressão dos pneus) 

TPS - Throttle Position Sensor (Sensor da posição do acelerador) 

TTC - Triumph Traction Control (Controle de tração Triumph) 

Vbatt - Battery voltage.

VIN - Vehicle Identification Number (Número de série/chassis do veículo)
