Maybe not as easy as hitting a button on the IBE, but you can change maps via laptop.

 

to the autronic via a Binary input to tell it to switch maps??

 

So was that you with the black EVO at H20?

 

Nope. Don't do the car show thing.

 

I was at the show with some friends.

 

You dont have to do Autotune.
You get the Autronic to control Boost.
You can still set it up to have a Hi/Lo boost switch.
When you tune it, you tune all for higher boost levels.
That way when you have lower boost, the correct fuel map is already there, Autronic uses Throttle position and MAP sensor input
as primary load base calculation, so you can play with boost what ever you like and the MAP sensor input will work out what air is there.

 

Most standalone systems run on a MAP sensor Mike.

Since you haven't played with a stand alone, i will explain.

MAP, stands for Manifold Air Pressure.
This senses what Absolute Air pressure or Vacuum you hace into actual Manifold.
The ecu is setup up with Basic engine Parameters,
from the Air Pressure reading and size of engine and basic base tuning, the ECU can accurately determine what air is present in cylinders.
If you have all you Fuel Mappings done up to say 2 Bar of boost say at 3 psi intervals, you can easily swith from no boost, to 10 psi, 15 psi 20 psi with out any retuning.
And the same goes with ignition maps.

And now i have gone to a MAP setup and revoved MAF, i believe its the best thing I have ever done, dont have to play with MAF sizes, linear air flow readings etc.

 

You can tune multile Fuel map and ignition map
Via LOAD (ie throttle position and MAP Sensor) and VIA RPM.
IE 3D MAP.

Other features include:

1. a. Eight injector drivers for full sequential operation on engines up to eight cylinders. May be set for 'semi-sequential' operation on engines having more than 8 cylinders. e.g:- 12 cylinder engine using 6 groups of 2 two cylinders.
b. All injector types catered for (0.9 ohm to 16 ohm coil resistance). Specify unit fitted with optional high current injector drivers for 0.9 ohm or twin injector applications.

2. User choice of manifold absolute pressure or throttle position as engine load input. Internal absolute
pressure sensor for simplified installation 0 to 200 kpa (0 to 29.4 PSI) and 0 to 300 kpa (0 to 44.1 PSI) available from stock. 0 to 450 kpa (0 to 66.1 PSI) available on request.

3. Single coil distributor, twin coil distributor or muilticoil distributor-less ignition configurations are possible on most engines.

4. Closed loop (feedback) boost pressure control for turbocharged engines with multiple calibration curves selectable by switch input or road speed (eg:- lower boost curve for use in low gear).

5. Closed loop (feedback) idle speed control.

6. Exhaust oxygen sensor input for sensing air/fuel ratio. Connect either a Bosch narrow band O2 sensor or for more demanding applications a Bosch wide band O2 sensor and Autronic Analyzer. The low cost narrow band sensor requires no interface adapters or expensive air/fuel ratio meters, and offers moderate accuracy and tolerance to leaded fuels. This function can be used to monitor air/fuel ratio during engine tuning or can be used for feedback control of air/fuel ratio for applications requiring exhaust catalytic conversion (feature available on request).

7. Diagnostic/Error indicator of sensor or ECU fault conditions with memory for detection of intermittent fault conditions.

8. Measurement of end correction for exhaust back pressure (applicable to turbocharged engines).

9. Control of engine cooling fans and coordination with air conditioner operation.

10. Programmable on/off output for solenoid or relay driving that operates according to engine speed and load (eg:- can be used for gear shift control or light, over rev indicator, inlet camshaft timing selection or control of a supplementary electric fuel pump that augments mechanical fuel pump delivery at low engine rpm only).

11. Precise spark advance control strategy for both static and dynamic operating conditions.

12. Unique calibration strategy allows accurate control of fuel delivery under both acceleration and deceleration.

13. User selectable spark and fuel delivery strategy for abnormal engine operation conditions to minimize possibility of engine damage whilst still maintaining engine operation.. (eg:- over heated or over boosted).

14. Comprehensive limp-home functions with user selectable default settings that ensure engine operation can continue after sensor failure has occurred.


15. User defined proportional output function that can be used for additional functions as outlined in 10 above or for a more sophisticated control function such as servo control of auxiliary butterfly for turbocharged applications requiring precise throttle control and minimum turbo lag.

16. Full compensation of engine control parameters for engine operation at any altitude (fuel delivery, ignition timing and boost pressure).

17. Adaptive learning (with memory) to minimize the number of user setups required and to provide optimal control of air/fuel ratio, boost pressure and idle stability.

18. Rev limiter with soft characteristic that uses a combination of fuel delivery and spark control.

19. Fuel pump safety shutoff. Pump stops 3 to 4 seconds after the engine stops.

20. Bi-directional input/output line for simultaneous connection of remote adjusting unit.

21. Standard unit is ultra light weight/compact yet has sufficient drive capacity for high power continuous duty applications. (one unit OK for all applications from motor cycle to large capacity twin turbo engines).

22. User configurable data logging of up to 17 channels with the selected channels being sampled as fast as 50 times a second. With 32k bytes of non volatile memory.

23. Optional interface unit to allow sequential operation without the need for separate crank/camshaft sensors or special multi-sensor distributor.

24. Fuel used pulse output to electronic or electromechanical counter with resolution of 0.1 liter (or use with trip computer).

25. Remote monitoring of all functions using telemetry adapter, ECU can perform simultaneous logging and telemetry.

26. Water injection/intercooler cooling for intake charge temperature control in turbo/super charged applications.
