  • New parts to work with Autronic

    I am happy to announce that we have preseries production on a range of products that is of interest for the Autronic tuning community.
    We have more parts that soon will be available, but will announce that later

    1) AUDI/BMW 55pin Plug&Play adapter
    Autronic SM4/SM3 adapter loom for applications on vehicles with 55-pin Motronic 1.3 ECUs, including Audi 200TQ 20V -91 AAN/ABY UrS4/UrS6/S2/RS2 / S4/S6 20v turbo 92-95, and a wide range of BMW vehicles, (including the V8 models), as well as a large variety of other model vehicles equipped with a Motronic 1.3 ECU.



    The adapter comprise an adaption circuit board (in box enclosure), which is strap configurable for variations in Mot1.3 pinouts depending on vehicle model, and a cable connecting the adaption board with the Autronic SM4/SM3. The cable will be available in at least two standard lengths. The motronic adapter could also have an ignition expander integrated.

    2) ImprezaMY98 64pin Plug&Play adapter
    Autronic SM4/SM3 adapter loom for Subaru Impreza GT 97-98 models with the 64 pin ECU connector.


    3) 5/6 output passive ignition expander.
    Autronic SM4/SM3 ignition output expander that handles applications with both 5 and 6 ignition outputs. Hermetically sealed 50 x 50 x 15 mm moulded box with 12 pin Mate&Lock connector, (which optionally can be fitted with water seal to achieve IP57 seal on the cable connector).
    (The passive *ignition expander is recommended mainly for
    dwell type ignition).

    4) 5/6/8 output fault tolerant active ignition expander
    Autronic SM4/SM3 ignition output expander that handles all applications from 5 to 8 ignition outputs. The active expander handles signal faults like, for example, spikes, ground induced false triggering, through use of digital signal error correction, thus producing clean & crisp expanded ignition outputs without false firing that is needed for use with CDI ignition. Controlled propagation delay on the ignition
    outputs between 1.0 < Tpd < 2.0 microseconds (pin to pin).

    First version is boxed in a 120 x 103 x 21 mm Alu casing, and sold preconfigured for either of the following modes:
    ***+VePulse
    ***-VePulse
    ***+VeDwell
    ***-VeDwell

    After some testing, a second model will be released, with similar specifications, but boxed in a 120 x 78 x 27 mm Alu casing, and featuring internal strap configuration for all modes +VePulse / -VePulse / +VeDwell / -VeDwell including different polatity on the outputs than on the inputs from the SM4/SM3. (Version 1 and 2 are pin compatible, and version 2 will replace version 1 in future).

    Pico Relay Sequencer

    Here is a summary of some product variants of the Pico Relay Sequencer:

    1) PWM fan controller
    Takes two 10 Hz PWM inputs, (f.ex from Autronic SM4 STEPPER/OUTPUT, INJ, IGN outputs), and controls two fans with high/low speed through relays.

    One input controls one fan so that a PWM duty of 50% turns fan on at low speed, and PWM duty of 100% turns on fan at high speed. The outputs will not switch simultaneously, keeping the high/low output switching separate by about one second, to allow the fan to soft start, and not draw excessive current.

    Pros:
    - Will use only two SM4 outputs to control two fans with high and low speed.
    - Soft-starts the fans, to avoid excessive inrush current on the fans.

    For example, the coolant fan on a Mitsubishi EVO6 will draw in excess of 56 Amp inrush current when starting from 0 rpm to full speed. Simultaneous start of coolant fan and condenser fan at full speed will generate voltage drops that repeatedly cause engine synch errors, and in rare cases can cause the fuel pump to momentarily stop.

    Product is implemented as a software configuration of the general Pico Relay Sequencer, and is tested and available for purchase immediately.


    2) SMC fan extender
    Takes the two fan outputs from, (f.ex), the SMC P&P EVO ECU and controls the two high/low speed fans on an EVO6 in a similar manner as the OEM control strategy. Coolant fan on will start on low speed if condenser fan is off, and if the fan is not turned on withing 30 seconds it will set fan speed to high. And if the condenser fan is already on, the coolant fan will go directly into high speed when SMC turns it on. Control of the two fans high/low speed will implement soft starting by separating the switching of the fan control relays with a timed delay, (as described in p.1 above).

    Pros:
    - Will allow SMC PNP installations to use the high/low speed coolant and condenser fans to its full capacity from the two
    available fan control outputs.
    - Soft-starts the fans, to avoid excessive inrush current on the fans.

    Product is implemented as a software configuration of the general Pico Relay Sequencer, and is tested and available for purchase immediately.


    3) Unipolar stepper driver
    From only two STEPPER outputs from the Autronic SM4, it will control a four pole unipolar stepper motor, (IAC), with four lowside drivers with a driving capacity of nom. 3.5 Amp. The stepper may be powered from any supply voltage, up to 42 Volts, that may be separate from the SM4 injector power supply. Internal coil clamping makes the control of the stepper motor relatively immune to voltage variations in the power supply, as compared to driving the stepper from p/p halfbridge drivers, where coil clamping is done to the supply +12 Volts, which generate stepper errors.

    Pros:
    - Will save two output pins on the SM4 when controlling a four pole unipolar stepper IAC motor, using only two outputs from the SM4.
    - Will allow controlling a stepper which is supplied with power else than the SM4 Injector supply voltage feed.
    - Will reduce stepper errors due to supply voltage variations.
    - Will be able to control a stepper motor at a higher frequency, than if it where controlled by p/p halfbridge outputs clamped to +12 Volts.

    Product is implemented as a software configuration of the general Pico Relay Sequencer, and is currently uder test and will be available for purchase later.


    4) PWM frequency rescaler
    Takes one 10 Hz PWM signal and generates a conditioned output PWM of the same percentage as the input PWM, byt at a higher frequency, (currently up to 4 kHz). Also generates an inverted complementary PWM signal with dead band control, for the application of either inverted PWM, or driving two pole solenoid actuators from one SM4 PWM output.
    It also generates one signal that turns on when the input PWM duty > 0% and turns off after a delay of 5 seconds after the PWM is at 0% duty.
    This can be used to control the fuel pump relay for a FuelLab PWM managed fuel pump, without the need for an extra output on the SM4 for controlling the pump relay.

    Pros:
    - A generic 10-30 Hz PWM output from either SM4 STEPPER/OUTPUT, INJ, IGN or PWM output can control an actuator needing a higher PWM frequency.
    - A two pole solenoid actuator, (like the BOSCH two tre pin IAC solenoid), can be controlled by a single PWM output of the SM4, and it need not be anything else than the generic 10 Hz PWM frequency.
    - A FuelLab PWM managed fuel pump will only need one PWM output from the SM4 to both control pump speed and pump relay.

    Product is implemented as a software configuration of the general Pico Relay Sequencer, and is currently under final development/test and will be available for purchase later.


    5) Road speed multiplexer
    Takes two HALL-level signals from ABS-sensors, (using a reluctor interface where no HALL level signals is available), and generates an output signal with either of min/max or average of the two as an output, that can be fed to an SM4 HSI input for road speed reference with traction control.
    Output frequency can be scaled as compared to the input signals.

    Pros
    - Saves one HSI input on the SM4 when using traction control.
    - Can generate a road speed signal for SM4 HSI3 on vehicles not equipped with a dedicated road speed signal.

    Product is implemented as a software configuration of the general Pico Relay Sequencer, and is currently under final development/test and will be available for purchase later.


    6) PWM to Frequency converter
    Takes a PWM input and transpates it to a frequency output. This can be used to generate spedometer output on vehicles where (replaced) the OEM ECU generated the specometer signal.

    Product is to be implemented as a software configuration of the general Pico Relay Sequencer, and is currently under development.


    7) Analog 0-5 Volt to frequency converter
    Takes a 0 to 5 Volt analog input signal and converts it into a frequency signal suitable for input on a SM4 HSI input, and thus usable as an extra analog input for the Autronic SM4.

    Pros:
    - Provides one extra analog input for the SM4 for each available HSI input.

    Product is implemented as a software configuration of the general Pico Relay Sequencer, and is currently under test and will be available for purchase later.

      Also a new GIA, "Ground Isolation Amplifier" are soon available.

      Will handle differences in signalground up to +/- 7 for 0 - 5 Volt, with a bandwith from DC up to 1,3 MHz. Fault less than 60 uV! Outstanding performance.


      Can be used with a Innovate lambda meter to Autronic SM4/SM3 & stock ECU. Maximum performance and the signalground on Autronic are not pulled to ground thru other components.

      Can convert reluctorsignal to hall signal.

      Can buffer eg. Lamdasignal to more units, can buffer signals from temperature sensors to both Autronic and stock ECU. Can use a VDO oilpressure sensor and output 0-5 volt signal related to Autronic sensor ground. Can use two pressure sensors and generate a 0-5 volt clean output, (testning pressure drops and more).

      Can be used with another temperature sensors and output "Autronic standard" signal so stock sensor can be used.


      Battery only for size compare!

      And much more things....

                      Here is a PnP adapter for Subaru 99-00, made as loom. Has even knock sensor support if fitted in Sm3/Sm4. Has auxiliary, lamda, optional air-temp and more.

                      We are producing a few before they will be replaced with the adapter type. To much work making a high quality loom adapter.


                      Ecu connector (wire side) will be sealed before shipping.

                          Toyota may be done in the future, from memory some toyota has components like iac powered from another source so they may need some active components added for a safe PnP.
