BMW 330 turbo EMU black

HI.

I'll going to install my Black EMU system to my BMW e46 330 turbo.

I was thinking of using DBW system, but do not really know how to go into the box with the cables from the pedal, etc.
There are 6 cables from the pedal, but I have no idea which is which.

As I understand, then these four go to the box from the pedal?

POS
SGND
POSinv
And last one +5v

I'm working on one in Canada.

DBW works. but you must use G2 and G10 as the throttle motor drivers.

TPS is also wired as the pedal + position sensor. this is also necessary.
select your other three inputs and you should have a working DBW.

the throttle response will be strange so you will have to play with the maps.

use two aux drivers for the idle control motor.

Thanks.

Do you know the wire color from the pedal, what color is the POS, SGND etc.

I might.. if your original ECU(DME) is a DME MS43 I might know. The wires themselves are also often numbered at each end when colours are common - so, colour is occasionally insufficient information. if you have cut the original end connectors off the harness and have lost the printed numbers you may have a great challenge in front of you.

If it's an original MS43 and the plugs are still there I can tell you which wire on which of the five ECU(DME) connectors apply to your drive by wire.

The WDS at BMW planet has the wiring diagrams.
http://www.bmw-planet.net/diagrams/release/en/

To install the ECUMaster Black,
I started at the BMW computer, made a list of conductors to connect and to delete
and after the list was complete proceeded to connect and delete them.

It was a lot of work and my boss owns the information but i'll try to help as much as I can.

I believe my boss will be offering a plug-n-play adapter for your application but that's a couple of months away.

one more little tip dont use AUX 1or 2 for the idle motor since thay dont have the flyback protection (no flyback enables 1&2 to be used for injector drivers during an 8cyl sequential install)

Can`t use anything except Hbridge 1a and 1b.

EcuMaster Sweden

DBW Throttle body must use H-bridge 1A and 1B
Idle motor can use any aux driver.
best to use flyback protected aux driver.
mine are on Aux 5 and Aux 2 - I added the diode.

I will build a new wire harness to the engine, so no pnp needed here

Yes i think the original is a ms43, and i have not cut off the connectors (yet) from any wire, only removed som connectors to sensors etc to build the new harness.
But the connector from the pedal is still there.

The idle motor have i delete from the intake system and
i will control the idle by the throttle body.

Det ser ut och lira bra PSI

(it looks like it works well PSI)

Nice drift there Karel

Do you know how to control the e46 electric fan? So far I have heard/read that the frequency is 100Hz and it works with PWM positive signal. But I haven't tested this yet.. If you know better, please share.

Are you using e46 original injector and ingition power paths (+12V from the stock wiring and stock fuses)?

Teriksson · Post by **Teriksson** » Fri Dec 16, 2016 8:00 pm

magelius. No i have not install my fan yet.

I'm using Bosch Bosch ev14 1300cc injectors and VAG ignition coils.,new wiring new fuses. &

Are you using ONLY the throttle body for ALS air bypass, or do you have bypass direct to manifold?

Yes, i used the DME Main relay and DME power distribution relay and fuses.

Mine works.
I used an Aux input and selected PWM for the CLT parameter.
the fan control module on the fan is expecting 100Hz.

same as the M3 E46 fan. See this link.

i did say IDLE motor... sorry bit of OCD kicking in

E46 guys. Did you install the EMU to the original DME location, which is located in the engine bay next to the brake booster and ABS unit?
All the wirings from the chassis is already there, so it seems to be convient loaction. Just thinking is it too hot place for EMU for optimal performance?
Other option is to install the EMU near the glove box and then the temperature is more stable (15-25 celcius degrees when driving). Any thoughts?

i installed it in the stock location.
I ran an upgraded signal and power ground from the block as required by the instructions.

it is an awkward location to work in because it is close to the hood hinge.

next time i would use the "flying leads" to save HOURS of work.

some of the E46 vehicles have a fan for the DME to prevent condensation.

I believe it is a suitable location and the ECU Master Black is a more robust ECU than the one offered by the factory 15 years previously.

if there is a critical failure in the 15 years that follow i suspect it will be something other than the ECU.

The DME cooling fan was new info. I checked and I don't have it in my setup. I think I will install the EMU some where in the drivers footwell area because I have flying leads kit anyway. I just use the stock E-box for original fuses and relays and install the wiring through the E-box.

Btw, you can find the "e46 Bentley manual pdf" easily from google. Lots of good stuff in the manual. MS 42.0 and 43.0 DME pin assignments etc. In case if you don't already have it.

Only mystery for me so far is, where to get +12V ignition signal from the stock wiring to wake up the EMU? Where did you guys took the signal?
I want to keep the original EWS. Is the original DME waked up (+12V ignition signal) with the signal from the EWS to the DME (pin 33 at 40-pin connector)? It uses the rolling code method and the codes should match between EWS and DME, sot that signal can't be used for EMU because it is digital data signal.

Do you have A/C working with EMU?
It seems that originally when you press the A/C switch button the signal goes first to the heater unit, and then the heater unit send message via CAN to the DME, "Activate A/C clutch", then DME controls the A/C clutch and A/C is on.

How this works with EMU, if the A/C on request is controlled via CAN?
