e1280s ECU De universele diesel ECU voor pompverstuivers en commonrail systemen
De mogelijkheden van de e1280s ECU zijn bijna onbeperkt als het om toepassingen gaat.
Deze ECU heeft alles in zich om ook dieselmotoren van verschillende fabrikanten te kunnen laten werken.
De hardware van deze ECU is geschikt voor het bedienen van maximaal 20 injectoren of 12 injectoren in mulitibust injectie modes waarbij 3 pilot 1 main en 3 post injectie gegeven kunnen worden. De inspuit hoeveelheid en inspuit hoek kunnen per cilinder ingesteld worden.
We hebben de mogelijkheden om de timing signalen van de motor te kunnen programmeren waardoor er geen aanpassingen nodig zijn aan de motor.
Naast de grote hoeveelheid analoge en digitale ingangen beschikt de e1280s ECU ook over 4 hi speed ingangen die optioneel gebruikt kunnen worden om het turbine toerental te kunnen meten en in de programmatuur gekoppeld kunnen worden aan de inlaatdruk regeling.
Deze ECU beschikt over minimaal 8 en maximaal 16 uitgangen waarmee de kleppen van de dieselmotor aangestuurd kunnen worden, zoals debiet/hogedruk pompen en brandstof druk regelingen en kleppen voor de turbodruk regeling en niet te vergeten de gloeipluggen en EGR.
Ook beschikt deze ECU over 2 seriële ingangen waar digitaal communicerende lambda en temperatuur sensoren op aangesloten kunnen worden. Deze optie is ideaal als er roetfilters gebruikt moeten worden en er bij een te lage uitlaatgas temperatuur het roet filter geregenereerd moet worden.
Uniek is ook dat U zelf door middel van de soft ware SEKUKU via blokdiagrammen zelf het programma kunt schrijven.

First test run of the 4.2L FSI Audi engine running on the 1280 Super ECU.
No modification were made on the engine and all functions are controller by the 1280ECU including direct petrol injection fuel pump(s) pressure control and drive by wire and VVT.
We used 2 direct fuel injector drivers board to operate the fuel injectors.
The direct fuel injector driver boards can be used for running direct fuel injection engine in conjunction with the e1290s ECU or can be used for testing injectors or educational purposes as a part for trouble shooing direct fuel injected engines.
The injector driver boards can be special produced for testing various types of injectors with a selector switch to match the injector characteristics.
Injector driver boards can run on 12V or 24V DC
Beta testing a Subaru MY06 drive by wire valve with a Adaptronic 1280 ECU
Pre testing DBW system with the special boards that can handle more power than the Aux outputs of the 1280ECU.
The board can drive DBW valves and other servo devices.
It can also be used to drive up to 2 fuel pumps.
All the testing is done in preparation for the direct petrol injected engines where we need to control the fuel pressure as well.

1. New Product Feature - MAP Prediction for the e420c!
Throttle response is one of those areas which has traditionally been hard to get right. It's been hard because it is the sort of condition that affects different engines very differently, depending on throttle size, plenum volume and engine capacity, as well as dynamic variables such as load and engine speed.
Most ECUs (including the e420c until recently) had options for additional enrichments based on the throttle opening, or a rate at which the throttle was opened, as well as options for additional fuel pulses out of the normal injection sequence. The enrichments often prove hard to get quite right, because a certain enrichment at one condition (such as opening the throttle to 10% off idle) doesn't give the correct amount at another condition (eg, full open throttle off idle).
The reason for this is actually fairly straightforward when you think about why an ECU actually should need throttle pump settings. It's because of two things:
Firstly, the MAP sensor doesn't respond immediately to a change in manifold pressure. It is possible to make the MAP sensor more responsive, but that can lead to unstable MAP readings, depending on plenum design and the pick-up point for the MAP sensor. So if you suddenly fully open the throttle off idle, the MAP sensor will still indicate 33 kPa absolute, where the plenum actually has a full atmosphere of air in it (100 kPa absolute). To provide enough enrichment to cover this problem, you would need 200% extra fuel! Clearly this is the wrong tool for the job. Instead of an enrichment, we should have a MAP signal the ECU can use which changes immediately the throttle is opened.
Secondly, unless the injection sequence is set up perfectly, there will be a lean spot as the injector pulse width changes within the ECU. This is because if the ECU delivers a pulse to the injector before the inlet valve opens, and the throttle is then opened before (or while) the inlet valve is open, the ECU can calculate the next fuel pulse as fast as it likes but it's already delivered the pulse for that stroke! So we need a way to give another injection squirt out of the normal injection sequence. Previously on the e420c (and other ECUs), this was done with a separate table of the milliseconds to deliver to the injector as a function of engine speed and/or load. Rather than doing that, we can now look at the change in the injection duration and give an extra squirt of the difference. For example, if the engine is idling with 2.2ms, and the throttle is suddenly opened, requiring 7ms of injection, the ECU can deliver an additional injection squirt of 4.8ms.
Setting this up is quite straightforward; all you need to do is tell the ECU the MAP value at different RPM/load combinations. This will be made adaptive (automatic) in future software/firmware versions.
Of course you can update your existing e420c with this new feature. Please visit our downloads page to download the latest software / firmware and start experimenting!

1. New Product Highlight - the e1280s Super ECU! Finalists in Engineering Excellence Awards 2009 and EDN Innovation Awards 2009!
After years of development and testing, the e1280s Super ECU is now released. This is without a doubt the most flexible ECU on the planet, short of designing your own from the ground up. This is because the way all the calculations and controls are performed internally is based on a series of elements which you can string together to perform any function you like. If you want a 3D table to provide an auxiliary output based on road speed vs ignition timing, for argument's sake, you can add it. The tables can all learn values as well, allowing adaptive closed loop fuel control, idle control and so on.
This patented technology has helped this product become a finalist in both the Engineering Excellence Awards (Control Systems and Communications category) and the Electronic Design News Innovations Awards (Best Application of Field Programmable Logic).
It also features:
12 switching mode injector outputs, with 720 degree end of injection programmable timing (by default, tuned against MAP vs RPM, but you could change this to anything you wanted. Injection duration is by default VE based, but again this can be changed)
8 current source ignition outputs for driving factory and aftermarket ignitors
8 current-limited, push-pull auxiliary outputs, all PWM capable at arbitrary frequencies (for example, you could make a 4-cylinder tacho output on a 7-cylinder engine by setting the PWM output period in ms to be 30000 divided by the RPM)
2 serial inputs for peripherals (eg wideband oxygen sensors, EGT probes etc)
2 knock inputs
Headphone output for listening to knock sensor inputs
16 analogue inputs (separate from knock inputs), of which 4 can be configured for temperature sensors
8 digital inputs, with programmable pull-up or pull-down resistors
4 vehicle speed inputs (for each wheel), configurable as digital or reluctor
5 engine trigger inputs, configurable as digital or reluctor (one crank, 4 cam, for up to 4 VVT channels)
USB connection to PC
USB host connection for datalogging to USB thumbdrive
Internal datalogging
Serial connection for Vidigauge
Standard 6 cylinder Nissan connector and pinout to suit R32-R34 GTR, R32-R33 GTST
This huge amount of I/O, coupled with the unique and patented flexibility, makes it the most flexible ECU on the market. It's ideal for custom installations where additional control is needed for functions not supported by our other products. It's also ideal for developers of alternative engine technologies, including different fuel types and induction configurations which all have their own particular control requirements.
Our team of engineers is currently developing base maps for various different engines. Please contact our tech enquiries for particular installation queries.
2. Product Review - Innovate Motorsports LC1 / TC4
At Adaptronic, we're always on the lookout for complementary products that work well with the whole car as a system, and can help the tuner or driver. Innovate Motorsports have developed a series of "modular" tuning devices which can be daisy-chained to provide several useful parameters.
The LC1 is a "lambda cable", which is a wideband air-fuel ratio sensor that works over a wide range of air-fuel ratios, and can either be permanently installed or installed only during tuning. By connecting its serial output into the serial input port on the Adaptronic e420c or e1280s, the tuner can see the wideband air-fuel ratio on the laptop along with the other gauges and parameters, and use the ECU to "close the loop" and provide fast self tuning.
The LC1 is well constructed, and provided you follow the heater and free air calibration steps, very straightforward to use.
The TC4 is another piece of instrumentation from Innovate, however instead of monitoring air-fuel ratios, the TC4 is an interface for four K-type thermocouple sensors. These can be used to measure anything that gets too hot for a thermistor, including turbine inlet/exhaust temperature, EGT, cylinder head temperature and so on. This interface is even more straightforward to use than the LC1, giving a very convenient means of monitoring several high temperatures simultaneously. As with the LC1, Adaptronic ECUs can read this serial output directly and display it on the laptop gauges, along with any other variables.
Perhaps the best feature of Innovate's product range is the MTS, or modular tuning system. This means that you can connect an LC1 and a TC4 at the same time, and monitor both air-fuel ratios and EGTs, using only one serial port.
Currently we are working on the development of the e1280s ECU for direct fuel injected.
Adaptronic pakt uit en heeft de eerste stappen ondernomen om de ECU systemen ook geschikt te maken voor direct ingespoten brandstof systemen voor zowel diesel als wel benzine motoren.
