1. Overview of OSCAR-N SAS controllers an their functionalities.

OSCAR-N MINI SAS

•Very fast Central Processing Unit 120 MHz.

•Built-in petrol injection emulator with resistance 100 Ohm.

•Full feedback diagnostic of gas injectors circuits (system

signalizes an error after detecting an circuit intermittence and

automatically goes back to petrol).

•Possibility of: connection and reading the parameters of one

Lambda probe -version LS or connection of separate wire

from ECU harness to cut-off petrol fuel pump circuit after

changeover to gas with programmable time delay -version FP.

•Possibility of starting the vehicle directly on gas by holding switch button.

•Feature of filtering petrol injector pre-pulses (extra-injections).

•Software makes possible to adjust parameters of fuel supply system in very large scale.

Besides the correction due the vacuum in the intake manifold, installer can adjust gas dosage

regarding to PM level, gas temperature and gas pressure. It is also possible to adjust

mixture dosage for each cylinder separately and possibility of preheating the gas injectors

before first changeover to gas.

•„Exit from cut-off on petrol” feature (from too high gas pressure during cut-off conditions).

•Calculation of the multiplier value corrections can be done by a single click on the

„Calculate adjustments” button in the software after collecting petrol and gas maps.

•Auto-adaptation feature ensures that during the driving on gas multiplier line is being

automatically corrected within desired ranges (tolerance in %) in places on the map where

petrol and gas lines are not close enough to each other (works even without connected PC).

•Feature of „full-injection opening mode” for chip tuned cars with petrol injectors constantly

opened during very high loads.

•Possibility to force gas injector to be opened at minimum opening time value (to avoid not

full gas injector opening when too slow injector has been installed).

OSCAR-N PLUS SAS

•All features present in OSCA -N MINI SAS are

included in OSCA -N PLUS SAS moreover it has all

features mentioned below.

•Possibility of connection and reading the parameters of

two Lambda probes at the same time.

•Separate wire from ECU harness to cut-off petrol fuel

pump circuit after changeover to gas with

programmable time delay.

3/42

OSCAR-N OBD CAN SAS

•All features present in OSCA -N MINI and PLUS

are included in OSCA -N OBD CAN SAS.

Moreover it has all features mentioned below.

•Built-in datalogger circuit activated by holding the

switch button during the driving makes possible to

Helpful to diagnose a malfunction when the car is out

of workshop.

•Possibility of erasing OBD errors plus monitoring

and making corrections of gas injection opening times regarding petrol injection Fuel Trims

separately for both Banks for OBD CAN protocols and for older OBDII protocols directly

from ECU harness (no OBD adapter necessary).

Improvements in SAS controller firmware version 10.92 / software version 1.10

ATTENTION:

All new features in OSCA -N SAS software version 1.10 will work properly only if the SAS

controller has been programmed with latest 10.92 firmware version.

Software 1.10 with firmware file in version 10.92 included, can be used to update any of SAS

controllers with older version of firmware (eg. 0.89).

In case of establishing connection with controller having firmware version older than 10.92 via

software version 1.10 it is highly recommended to run the update procedure as described in last

chapter of this manual.

After upgrading controller's firmware from version 0.89 to 10.92 it will be no longer possible to

work with that controller with software version older than 1.10 nor downgrading the controller

firmware to older version.

HINT:

When the mouse cursor will be held over a particular software functionality for time period

longer than 3 seconds a balloon tip will appear there. It will be containing short description how

given functionality works.

List of new key features an improvements in SAS controller firmware version 10.92 /

software 1.10:

1) PM signal can be read out directly from the petrol injector (no need to connect PM signal

wire)

2) Gas leakage occurrence is being indicated and registered in ECU's memory when the gas

pressure before engine start is lower than the value of "Minimum gas pressure".

3) Automated self-connection via the Bluetooth interface during software start-up.

4) Automatic information about the possibility of upgrading software through Internet.

5) Automatic scaling of calibration map range depending on the maximum injection time

achieved.

6) Active „Calibration map” assistant (using the Up and Down keys when mapping, changes the

value of the multiplier for actual petrol injection time).

4/42

7) Active „ PM / injection time map” assistant (using the PgUp and PgDown Up Down when

mapping changes the enrichment in the active map area).

8) The program automatically starts to record the oscilloscope signals at each start-up.

9) Possibility of introducing parameters of self-defined non-standard gas injectors.

10) Automated "Mazda leaning" feature (when car switches the injection control strategy from

Sequential to Semi-sequential).

11) Possibility of mixture extra-enrichment during rapid accelerations.

12) Exit from cut-off on gas through reducing the gas injection time during big pressure growth

for a defined number of injection cycles.

13) Possibility of hiding from the end user temporary switchover to petrol.

14) Buzzer signal during switchover between fuels.

15) Protection of multiplier settings after calibration against changes caused by pressing

"Calculate multiplier" button.

16) Opportunity to protect controllers settings with a password.

17) Overlapping fuel cycles when switching (for a set number of cylinders cycles are given

simultaneously petrol and gas).

18) Integration with vehicles equipped with Start & Stop system.

19) More precise method of petrol and gas maps collection.

20) Support of gas and reducer temperature sensor NTC 6.8 kOhm.

21) More fluent sequential switchover between fuels.

22) Possibility of automated emergency start with gas without need to hold the switch button.

23) Possibility to read and view the controller's settings and to preview oscilloscope from the

file without necessity of establishing connection with the controller.

24) Possibility of saving in the controller's memory the size of mounted injector nozzles and five

most recent service maintenance inspections.

25) Constantly visible indicator of the collected calibration maps quality in the whole range of

engine loads.

26) Support of for new switch LED-7 model with built-in buzzer and plug (no need to solder

the harness wiring).

27) Possibility to set separate neutral OBD points for the engine working on idle and at higher

PM. (feature available only in OBD CAN SAS)

28) Support of "inverted" OBD corrections. (feature available only in OBD CAN SAS)

2.3. Proper installation of OSCAR-N SAS ECU

During the installation of OSCA -N SAS sequential gas injection system it is suggested for the

wire set to point downwards. It is also suggested that it should be placed in such a way to avoid the

negative impact of high temperature and humidity. It is highly prohibited to spray ECU box with

water jets or expose it to long lasting contact with water.

The +12V ignition key red-white wire from ECU harness needs to be connected to the place in

which +12V voltage appears from the moment of turning on the ignition key to ACC position, do

not drops below +9V during engine cranking and remains stable during all the time of engine's

work. Voltage should drop to 0V shortly after turning off the ignition key.

It is recommended to check that the circuit of vehicle's element to which we've connected to doesn't

became temporarily powered off during engine's work like eg. air-conditioning compressor power

supply wire.

It is highly recommended to connect +12V ignition key red-white wire from ECU harness into

original vehicle's +12V ignition key circuit.

2.4. Selecting proper type of EG2000 GOLD LABEL injector accor ing car's

horsepower

The injectors efficiency should be selected in such way so that at low and high engine load

conditions the petrol injection opening time on gas should be equal to petrol injection opening time

on petrol. Tables given below should help to make right choice.

You might also use “EG2000 Assistant” available in OSCA -N SAS software.

In case of using standard valve type injectors like AIL IG1 You can use the “Nozzle calculator”

available in OSCA -N SAS software.

Attention:

Algorithm assumes that reducer's differential pressure has been set at 1 bar (for LPG reducer)

or 1,8 bar (for CNG reducer). Calculated values are only approximate values and it is

recommended to start drilling the injector nozzles from a diameter smaller from calculated

one by 0,2 mm and depending on the communicates during autocalibration eventually

increasing it by step of 0,2 mm. Table given below should help to make right choice.

2.5. Usage of changeover switch mo el LED-5 an mo el LED-7

2.5.1. LED-5 mo el escription:

Fuel state io e -the yellow diode located in top right switch corner show current fuel status. It can

indicate 5 following states:

1) turned off -system is in petrol mode

2) blinking at 1Hz frequency (once per second) -system awaits for reaching min. reducer

temperature

3) blinking at 2Hz frequency (twice per second) -system is in Auto mode and awaits for

reaching other conditions required for changeover (eg PM, preheating injectors etc.)

4) blinking at 4Hz frequency (4 times per second) -system is signalizing an error (eg.“Low gas

pressure error”), which is causing instant changeover to petrol

5) emits light constantly -system is in gas mode.

Gas level status io es -4 diodes shows amount of fuel level left in the gas tank. 4 diodes emitting

light simultaneously indicate full tank. All 4 diodes turned off means that the gas tank is almost

empty.

Fuel type selection switch -every single press of the button changes the type of selected fuel.

For an emergency start of gas -without usage of petrol (eg. when the petrol fuel pump has been

damaged) it is necessary to:

1) press and hold the switch button before starting the engine,

2) move the ignition key to ACC position,

3) wait for opening of solenoid valve,

4) start the engine on gas,

5) release the switch button.

Attention:

In OSCA -N OBD CAN SAS pressing and holding the button for 5 seconds during driving

on petrol or gas will enable/disable registering the system data parameters to the controller

memory. Later on recorded parameters might be downloaded to the PC with diagnostic

software.
