The following types of software modifications are available for order or purchase. Any changes in the file are hinted at in the original filename as suffixes.
Stage1 ECU tuning
Suffixes: [stage1], [st1], [tune].
Example: 2E46104005_tune.bin – tuning file for the stock: 2E46104005.bin
“Stage 1” tuning refers to a type of chip tuning that involves modifying the programming of a vehicle’s electronic control unit (ECU) to improve its performance. Stage 1 tuning is typically the first and most basic level of tuning that can be done to a vehicle.
Stage 1 tuning is designed to provide a moderate increase in horsepower, torque, and acceleration, and may be achieved through a variety of methods, such as optimizing the air-fuel ratio, adjusting the timing of the ignition, and modifying the fuel and exhaust systems.
Stage 1 tuning is generally considered to be the least invasive and risky type of tuning, as it does not typically require major modifications to the vehicle’s drivetrain or other systems.
Configuring environmental systems (Decat & disabling the oxygen (O2) sensors)
Software disabling the oxygen (O2) sensors and associated DTC codes.
Suffixes: [E0], [E2], [E2Catoff].
Example: 2E46104005_tune_E2.bin – tuning file for the stock 2E46104005.bin
Disabling the oxygen (O2) sensors in a vehicle’s exhaust system. All DTCs (Diagnostic Trouble Codes) associated with these systems will also be disabled.
Oxygen sensors are installed in the exhaust system to measure the oxygen content of the exhaust gases. This information is used by the vehicle’s electronic control unit (ECU) to adjust the air-fuel ratio and maintain proper emissions levels.
Disabling the O2 sensors can be done as part of a performance modification, as it can allow more fuel to be delivered to the engine and potentially increase horsepower and torque. However, disabling the O2 sensors can also result in higher emissions of harmful gases and may be illegal in certain areas.
Changing the maximum speed limit: “Speed limit”, “SL”, “Vmax off”
It is possible to change the maximum speed limit of a vehicle by modifying its electronic control unit (ECU).
Suffixes: [SPL250], [SP200], [SL250], [SpLim250].
The number means the new value of the maximum speed. It can be 250 km/h as in this example or any other value.
Example: 89663-60M00-A_Stage1_SpLim250.bin – tuning file for the stock 89663-60M00-A.bin
EGR off – disabling the exhaust gas recirculation (EGR) system
Software disabling of EGR valve and associated DTC codes.
Suffixes: [EGR], [EGR_off].
Example: DE5I500E_759B364007_Stage1_E2(EGR_off).bin
“EGR off tuning” refers to a type of chip tuning that involves disabling the exhaust gas recirculation (EGR) system of a vehicle. The EGR system is a emissions control device that is designed to reduce the amount of nitrogen oxides (NOx) in the exhaust gases of a vehicle. It does this by recirculating a portion of the exhaust gases back into the engine’s combustion chamber, where they can be burned again and reduce the amount of NOx emissions.
Disabling the EGR system can be done as part of a performance modification, as it can potentially increase horsepower and torque by reducing backpressure in the exhaust system. However, disabling the EGR system can also result in higher emissions of NOx and other harmful gases.
DPF off – disabling the diesel particulate filter (DPF)
Software disabling the DPF system and associated DTC codes.
Suffixes: [DPF_off], [DPF].
Example: 1860D05501_H1C54P27_TKU2HKU28101_DPF_off_EGR_off.bin
“DPF off” refers to a type of chip tuning that involves disabling the diesel particulate filter (DPF) of a diesel-powered vehicle. The DPF is a emissions control device that is designed to reduce the amount of particulate matter (PM) in the exhaust gases of a diesel engine. It does this by trapping and burning the PM, which helps to reduce emissions of harmful pollutants such as carbon monoxide and nitrogen oxides.
Disabling the DPF can be done as part of a performance modification, as it can potentially increase horsepower and torque by reducing backpressure in the exhaust system. However, disabling the DPF can also result in higher emissions of PM and other harmful gases.
IMMO off – disabling the immobilizer system
Software disabling the immobilizer system.
Suffixes: [immo_off], [immo].
Example: 37805-RA0-J620_E2(EGR_off)_Immo_off_CHK(ok).bin
“IMMO off” refers to a type of chip tuning that involves disabling the immobilizer system of a vehicle. The immobilizer is a security feature that is designed to prevent unauthorized use of a vehicle by disabling the engine if the correct key is not used to start the vehicle.
Disabling the immobilizer, also known as “IMMO off”, can be done as part of a performance modification or for convenience purposes, as it allows the vehicle to be started with any key. However, disabling the immobilizer can also increase the risk of theft.
EVAP off – disabling the evaporative emission control
Software disabling the evaporative emission control system and associated DTC codes.
Suffixes: [EVAP_off].
Example: MD369099_262106_EM2621 E2 EGR_EVAP_off.bin
“EVAP off” refers to a type of chip tuning that involves disabling the evaporative emission control (EVAP) system of a vehicle. The EVAP system is a emissions control device that is designed to prevent the release of fuel vapors into the atmosphere. It does this by capturing and storing fuel vapors in a charcoal canister, and then releasing them into the engine to be burned during normal operation.
Disabling the EVAP system, also known as “EVAP off”, can be done as part of a performance modification, however, disabling the EVAP system can also result in higher emissions of fuel vapors and other harmful gases.
SAP off – disabling the secondary air injection
Software disabling the secondary air injection system and associated DTC codes.
Suffixes: [SAP_off].
Example: 89663-60M00-A_Stage1_E2(SAP_off)_SpLim250_noCHK.bin
“SAP off” refers to a type of chip tuning that involves disabling the secondary air injection (SAP) system of a vehicle. The SAP system is a emissions control device that is designed to reduce the amount of hydrocarbons (HC) in the exhaust gases of a vehicle. It does this by injecting a small amount of air into the exhaust system to help burn off any remaining HC.
TGV off – disabling the tumble generator valves
Software disabling the tumble generator valves and associated DTC codes.
Suffixes: [TGV_off].
Example: AZ1H400W_6D04503007_Stage1_E2(SAP_TGV_off)_SpLim_250_CHK(ok).bin
“TGV off” refers to a type of chip tuning that involves disabling the tumble generator valves (TGVs) of a vehicle. TGV valves are components of the intake system of a vehicle that are designed to improve the airflow into the engine. They work by creating a swirling motion in the intake air, which can help to improve the performance of the engine by increasing the air-fuel mixture’s homogeneity.
FANCorr – adjusting the fan on temperature
Suffixes: [FANCorr], [FANCorrect].
Example: EA1M220F_80323C7107 Stage1 E2(EGR(off) FANCorrect CHK(ok)
“FANCorr” stands for “fan speed correction”, and it refers to a type of chip tuning that involves modifying the speed of the cooling fan on a vehicle.
Checksums
Calculation of checksums can be performed or not (required to be performed when writing by means of the loader).
Suffixes:
- [CHK(ok)] – checksums recalculated,
- [noCHK] – checksums not recalculated . If there is no suffix – consider that it is not fulfilled,
- [CHK(fix)] – сhecksum verification disabled.
Example: 37805-RZV-E530_Stage1_E2(EGR_off)_CHK(ok).bin
Calculating checksums involves performing a mathematical operation on the data stored in the ECU in order to generate a unique numerical value that represents the data. This value, known as the “checksum”, can be used to verify the accuracy and integrity of the data. If the data has been modified or corrupted in any way, the checksum will not match the expected value, indicating that there is an error in the data.
AdBlue / SCR off – disabling selective catalytic reduction
Software disabling the selective catalytic reduction system and associated DTC codes.
Suffixes: [Adblue], [SCRoff].
AdBlue is a brand of diesel exhaust fluid (DEF) that is used in some diesel-powered vehicles to reduce emissions of nitrogen oxides (NOx).
“SCR off” refers to a type of chip tuning that involves disabling the selective catalytic reduction (SCR) system of a vehicle. The SCR system is a emissions control device that is used in some diesel-powered vehicles to reduce emissions of nitrogen oxides (NOx). It works by injecting a small amount of diesel exhaust fluid (DEF) into the exhaust gases of the vehicle, which helps to break down the NOx into harmless water and nitrogen.
