Ecumaster forum

could anyone help me out ? Updated ECU firmware, downloaded latest version of software where it says that e46 CAN VSS is supported now. But my ECU still doesnt see vehicle speed. dashboard works fine by CAN... but no VSS. What is wrong with settings ? What CAN ID to use ?

Hello,

Would like to get my vss work throught can module. Anyone done it yet and can help me with CAN ID and CAN ID byte idx values ? maybe someone can share screenshot of VSS settings with CAN Module on e46.

problem is that throttle body even when ignition is off, is a little bit opened, so its mechanical 0 position is not fully closed see attachment, throttle body by its self is always little bit opened, and i need EMU to rotate it backwards to fully closed. My tuner who has a LOT of experienced with e...

So i have issue with e46 DBW, basicly throttle body wont fully close, and IDLE is 1600 rpm, basicly home position of Throttle body (when no connected to EMU) is little bit opened about 2-3%. When i try to invert dbw output in EMU soft and hit throttle pedal throttle body is fully closed. But as i le...

Try changing the first colum in DBW characteristic to 1 or 0

There is no point changing that, because my actual value stays always in column with 5%. So red crosshair is always above the 0 column...

Anybody knows how to set up M54 dbw ? i have idle 1400 when it should be 900 i have problem with min position of throttle body, it is 4% but target is 1%, when i turn ignition off throttle body 0 position is not fully closed, and as i understand original ECU can change polarity of throttle body and ...

So got problems on my m54 engine, EMU switches main relay as i put battery wires on. Even when ignition is off and car key is in my hand emu turn main relay on and as i use original bmw wiring main relay is also chargins some sensors and ignition coils so my ignition coils start to melt ... already ...

Will start my M54B30 in a few weeks so will need base maps to make it easier, if somebody has base maps please share

right now i have connection as follows : EMU - CAN BUS module - Car CAN. And everything works great CAN is working Can Dash (bmw e46) working, check engine light working and so on ... Where should i connect CAN BT module and where to put resistor in it ?

So i have can-bus bluetooth module dont understand this thing : 120 Ohm resistor must be present on each end of the bus between can-h and can-l. I have only 1 resistor with my module, so i have to put it between two wires of Can-h and Can-l ? or there should be two resistors on both ends between two...

When i turn ignition on i have same noise as on this video.

Use D8 I used D8 as TPS in and D7 as sensor ground for pedal position sensor, When i turn ignition on there comes whistle sound from throttle body is that ok ? Also i have VDO 408238424001 throttle body, when i choose it and sellect all inputs in software, when i turn ignirion off and turn it on ag...

Hello, Have a problem wiring my DBW module, actually DBW is not a problem to connect, problem is in accelerator pedal signal to ECU , as i understand i should connect signal wire from accelerator pedal to ECU TPS in pin. But i have two signal wires from accelerator pedal. So how could i do now ? In ...

Thanks for so quick reply !

Ok so if i have only one solenoid per cam i connect as standart VVTI system with diode (diagram), not like double vanos ? Also if you already answered me do you know if m54b30 has ignition coils with or without amplifier (picture) ?

Im right now working on wiring of my M54 stock wiring loom to make in capable with EMU. I saw that some BMW has build in diode in vanos plug and needs to change polarity. However in my plug(on picture) there is only two wires entering plug and no diode in there, i have pretty same socket as i have o...

What is your PWM frequency ?

Sorry me for my bad english, do you mean EMU must be powered with diode ? Or EMU must be connected to fixed 12v not ignition switch 12v ?
