BMW E46 Plug & Play ECU MASTER Engine Management
The BMW E46 M64 has two ECU types. DME43 or DME45 DME45 came into production July 2003 but there will be some cross over so we advise checking. Either check the ECU itself or check the MAF. DME43 have a 3 pin MAF DME45 have a 5 pin sensor. (We still advise checking the ECU itself but this is a good guide)
BMW E46 ECU Master PnP ECU Kit for the M54 E46 including the EMU Black. The EMU Black controls fuelling, ignition and auxiliary systems on 1-12 cylinder engines including those with drive-by-wire throttles and VVT.
It can drive up to 6 passive or 12 smart coils directly and does not require external amplifier/power modules to achieve this. Sophisticated drive-by-wire strategies provide a wide range of throttle control along with advanced plausibility (fault/error) checking for safety.
Free, easy to install firmware upgrades further improve system capabilities (e.g. new strategies, trigger patterns, CAN data streams).
The EMU Black features more built-in value than any other aftermarket ECU. It easily matches the functionality of other stand-alone management systems with multiple inputs and outputs. Unlike many other ECU systems, the EMU Black has built-in wideband lambda input (Bosch LSU 4.2, and LSU 4.9 sensors wire directly in), MAP control connector (4 bar MAP sensor on board), 2 EGT probe inputs and an input to directly connect a Flex Fuel ethanol content sensor. All of this provides greater flexibility, reduces costs and negates the requirement for external or supplemental signal conditioning control systems and the associated wiring that other management systems require.
Technology:
The EMU Black is assembled according to IPC-S-815A standards to ensure high reliability of the product. The device is manufactured on an automated assembly line with optical inspection, automatically tested including burn-in. The PCB board quality and design, special surface coating and IP60 enclosure keeps the device operational in the harshest environments. The components used allow continued operation in a very wide temperature range (AECQ-100 GRADE 2 (-40 to +105˚C).

Ordered before 1pm, fitted this weekend.
In-stock parts ordered before 1pm are dispatched the same day. UK and Ireland typically arrive next morning, worldwide as quick as three days. Times do vary, but that can mean the part is on the car within a few days and she is back out blasting the roads by the weekend.

Straight answers
The questions you were about to open a chat about.
How do I know it will fit my car?
Send us your chassis code or your reg in the chat and we will confirm before you spend anything. If you order and it turns out to be the wrong part, we swap it.
“Had a mix up with the item description (order wrong part) they was quick to email me and see what part I was meant to order and substituted it for no extra cost!”
Bradley Page, verified customer, 31 Jan 2025
When will it actually arrive?
In stock and ordered before 1pm, it leaves the same day. UK and Ireland is usually next day, occasionally 1 to 3 days. Europe 1 to 5 days, rest of world 3 to 5 days on express.
If something is not in stock, we will email you right away with an ETA and any available substitutes. On the rare occasion it does not work out, we will happily refund your order.
Will I get stung for customs or import VAT?
No. The price you pay on our website is what it will cost to be delivered to your door. You will not receive any surprise surcharges after ordering.
What if I change my mind?
30 days on all stock items, full refund on the parts. If you ordered the wrong thing we will help you get to the right one for as little money as possible. We have been there.
What warranty do I get?
Everything on our website is covered by the standard manufacturer's warranty.
If you ever need to claim, we fight your corner. We will do everything in our power to make sure you are looked after, rather than leaving you to argue with a manufacturer on your own.
Can I pay it off over a few months?
Yes. Klarna and Shop Pay Finance are both at checkout, so you can spread it without putting the build on hold.
Can I just ask someone what to buy?
That is the bit we are actually good at. We run our own race team and workshop, so you are talking to someone who has fitted it, broken it, and fitted it again. Hit the chat and tell us what the car is doing and what you want it to do.
