Many 7M, 1JZ, 2JZ & 1UZ Proven installations around the world, gives all owners of boosted cars an option when wanting to control larger injectors, ignition timing, fuel delivery and so much more.

Not every customer wants to replace their proven factory ECU, nor do they have to. With the ECU Master DET 3, you maintain your factory computer and install this as a true piggy-back device. Meaning your factory computer controls all the entire car as usual, EXCEPT you now gain control over all the parameters below to off true tuning in an easy to use graphical user interface.

This unit comes with a built-in 2.5 bar map sensor so you have the ultimate piggy back tuning device. Easy to use, easy to set-up with an amazing amount of engine control.

Proven on cars up to 800HP running factory ECUs. We have wiring diagrams for our customers for 7MGTE and 1JZGTE, so you're not left hung out to dry.

The ECU Master is produced in Europe and is sweeping the Continent by storm. For Supra owners familiar with the HKS VPC/GCC alphabet soup combination that powered many Supra's to 800HP, this replaces that type of device and then blows it out of the water with finite control of not only fuel curves, but also ignition!!

Features that boosted car owners love on this unit, "launch control", "boost control" "MAF to MAP auto conversion" The features that impress Supra owners the most in the ECU Master Digital Tuner III are:

Internal Logging

Amazingly Accurate Boost Control

Launch Control (Active 2 Step)

Close Loop O2 Feedback

Incredibly Accurate Timing Control

Large Flexibility of Inputs/Outputs

Speed Density Conversion (MAF to MAP)

Automatic Air Fuel Ratio w/ Closed Loop O2

Replaces all GReddy eManage devices, MAP ECU, APEXI AFC, etc. From the leaders in global Lexus and Supra performance SupraStore! This is a tuning device, not an AFC with a few knobs, so you will need to read the 45 page manual, understand the processes and then have at it.

Note: If you're a 7M owner and want to delete the AFM, then you will need to purchase an intake air temperature sensor (IAT) from the drop down menu. The ECU Master Tuner III will need this input.

For those interested in automated boost control, then the ECU Master Tuner III will take an input from a boost control solenoid and control boost! We have made this process simple by offering a boost control solenoid kit that you can wire into your ECU Master Digital Tuner III!

Can I store maps for various applications? Absolutely!

FUEL DELIVERY
Digital ECU Tuner 3 is capable to influence fuel delivery in several ways :

*The first one is to modify MAP or MAF sensor analog signal. The device is able to change signal in step of 0.005V. This fact as well as internal signal interpolation allows incredible control over fuel delivery.

*The second possibility is to adjust frequency of MAP/MAF sensors with resolution of 1Hz. *Other alternative is to use additional injectors controlled by 3D table based on RPM and user defined load.

*The last option is to direct control injectors opening time using both high current outputs. This feature allows to control injectors with extremely high flow and will be available soon.

IGNITION ANGLE CONTROL
Device is capable to alternate ignition timing in wide range of ignition systems. Due to the state of the art ignition input, device is able to modify inductive signals form VR sensors (differential and single ended) with adaptive threshold and true zero cross detection as well as unipolar signals common for Hall and optical sensors. Moreover the device is able to control ignition amplifier driving signals (dwell time is considered). Actually Digital ECU Tuner 3 supports most common ignition patterns like 60-2, 36-1, 36-2, Multitooth, Ign modules signals, EDIS SAW signal. Due to upgradeable firmware new patterns will be available soon.

BOOST CONTROL
Using 3 way solenoid and one of PWM 3D table, the user is capable of controlling boost (solenoid DC) vs RPM vs user defined load and 2 correction tables (eg. TPS scaling). Using VSS signal there is possibility to scale boost according to vehicle speed. PID controller based Boost Control will be available soon.

DIGITAL SIGNALS
Using digital input, user has wide range of tools to influence frequency of the signal. The signal can be modified using 3D table (load vs RPM) in additive or non linear additive way. The range of supported frequency is 1Hz-4Khz, what is enough for most signals that can be found in automotive industry (MAP, MAF, VSS). Signals can be clamped for minimum and maximum frequency. Digital input can be used as load or correction what opens new possibilities in car tuning (like speed dependent boost, frequency MAF based load, etc.)

TABLES
Device has four 16x16 tables (load vs RPM) for fuel modification, PWM and ignition. Each table has additional two correction tables 16x1. All table's values are interpolating according to load and RPM value what gives very smooth control over the engine. Tables can be modified in real-time when the engine is running, so tuner is able istantly to see what is the engine response. Load can be assigned to any analogue input as well as for frequency one. Due to integrated DataFlash there are two set of all maps. The user can switch them using Map Switch input. The switch time is less than 5ms and doesn't influence engine running. This feature is very usable for different fuel types, different boost settings, etc. Tables also can be covered with AFR (each cell has corresponding AFR value from log).

MAF TO MAP CONVERSION
The device has unique feature that enables automatic conversion between MAF sensor and MAP. Based on logged data during learning process the device generate output 3D table that convert MAP sensor voltage to appropriate level for given engine load. This feature works for analogue MAF as well for frequency one (using analogue MAP sensor). This feature is very useful in cars where MAF sensor is an orifice. It allows also using atmospheric BOV valve in turbo cars equipped with MAF sensors.

DATA LOGGING
Digital ECU Tuner 3 has a very powerful data logger. Logger is the main tool used for perfect mapping of engine. Each parameter like RMP, analogue inputs, accumulator voltage, PWM, ignition angle, all outputs are recorded and the can be used for further analysis. Log can be save to file and send to techsupport when there are any problems. Data can be retrieved by Windows Client or stored into internal DataFlash (up to 16 hours depending of required logging frequency). It is extremely important in sport events, where data can be analysed after each race.

To make reading logs easier, user can assign appropriate scale to each signal. Due to this fact user can see AFR, kPa, percents, etc. instead of Volts.

ROAD DYNO
During mapping engine, it is important to have a tool that can indicate if we go into right direction. Using road dyno we can compare car performance during mapping and we can analyse power and torque according to absolute pressure, AFR and other logged parameters.

LAUNCH CONTROL
This feature is very important in racing and drag racing cars. User can define RPM limit, ignition retard, and fuel enrichment for launch control procedure.

PARAMETRIC OUTPUT
Digital ECU Tuner III has a parametric output (4A) what can be activated when user defined condition is meet. As condition variables can be used all device inputs.

FUEL IMPLANT TECHNOLOGY
Fuel Implant technology is unique feature of Digital ECU Tuner 3 device. It turns the device into fuel Stand Alone system! DET3 directly controls injectors (batch or bank fire) calculating fuel dose based on Speed Density or Alpha-N algorithm. Due to this unique feature it is possible to take full control of fuelling, disabling ECU auto-adaptation. Fuel Implant technology simplify modification by allowing main ECU controlling tasks like idling, ignition timing (ignition angle can be modified by DET3 device), fuel pump relays, etc. DET3 in stand alone mode shares sensors like IAT, CLT with main ECU what decreases installation costs. There is very advanced implementation of Speed Density algorithm with all required parameters like acceleration enrichments, warmup enrichment, afterstart enrichment, barometric correction, etc. Due to this fact modified engines are driveable as well as factory ones.
