1. Direct Injection ECU of third-generation
Data: 22/10/ Rev. 1
Direct Injection ECU of third-generation

2. Simplify the installation
Targets
Simplify the installation
Give to customer the possibility to make their own installation on new vehicle without the presence of AEB staff.
Reduce the gasoline consumption

3. What’s new – hardware side
New gasoline injectors emulation stage
Compatibility with electrical interfaces, algorithms and monitoring functions implemented on new gasoline ECU (Opel, Nissan, Renault …)
Full range (0 – 14 A) of the emulated current level
Potentially we have now the opportunity to cut all gasoline injected
New gasoline injection reading stage
Possibility to acquire the profile of the injected current
Ability to read both negative or positive signals
Different hardware configuration options available
Double CAN interface
High speed data transfer on dedicated bus (in development)
Expandable system
Dedicated output for timing advance processor driving

4. New injectors emulation stage – into the topic
Features:
The current on the original injector can be emulated in a precise way
Lower heat dissipation on Gas ECU
Reduced diagnosis possibility on original ECU
The ability to drive up to 14 A gives the opportunity to completely cutting petrol  reduction in fuel consumption
Note: to refresh the gasoline injector it’s possible to introduce dedicated injection (split fuel) in particular condition

5. New injection reading stage – into the topic
Current on the gasoline injector acquired using an oscilloscope
(green trace)
Features:
The automatic acquisition of the current profile allows the customer to convert new vehicles without the presence of staff AEB.
Automatic correction of the emulation profile in case of different managment of the gasoline ECU (after fw upgrade).
By reading also the positive signal the gasoline injection time is correctly measured even when the precharge time is variable.
Current on the gasoline injector acquired by the new hardware reading interface.

6. Double CAN interface – into the topic
OBD Plug
OBD CAN BUS
(as actual ECU)
Feature:
System expansion with external modules
Module 1
(Valves)
Module 2
(TAP)
Module n
(data logger)
CAN
Interfacce
Proprietary
CAN BUS
Features
Acquisition for an accurate problem solving analysis
Qualitative measures on the signals

7. What’s new – firmware and software side
Features introduced
Ability to manage 3 cylinders engine
Opportunity to acquire RPM from hall effect cranckshaft sensor.
Advanced gasoline pressure emulation management (read only, set maximum pressure on gas, ...)
Possibility to manage a correction for second bank 2 in two bank engine application
The calibration map for the of extra injected management no longer requires the programming of the ECU with a dedicated firmware, it’s just necessary to set the corresponding item on the software.

8. What’s new – firmware and software side
Advanced parameters acquisition with oscilloscope
Possibility to graphically see the signals changing.
Possibility to insert markers for easily identify particular operating conditions.
Possibility to manage cursors for time and values evaluation
Possibility to save, load, export and print acquired signals.
