BMW M60B40

[pepifebles]

Hi guys,

I have bought other Emu to BMW E30 with M60B40 engine (4.0 V8). Does anyone have a base map for this?.
In Poland there are many Volvo with this engine

Thanks

[pepifebles]

Anybody??

Hi!

First of all you need to connect crank sensor, IAT, CLT, TPS, injectors and coils.
You need to connect two coils in one output.
The firing order of your engine 1-5-4-8-6-3-7-2 with cylinders numbered 1-4 from front to rear of the LH bank, and 5-8 from front to rear of the RH bank.

So the coils should be connected:
1 together with 6 and to EMU ingition output #1
5 together with 3 and to EMU ingition output #2
4 together with 7 and to EMU ingition output #3
8 together with 2 and to EMU ingition output #4

Next connect timing lamp to cylinder 1 and try the following trigger setup:




If there will be no spark check if the gap of 2 missing tooth on the EMU scope looks correct. If not change the trigger edge from falling to rising (it depends how you connect the sensor to EMU)

Hi,
I'm sorry for steling the thread, but we have similar setup and I thought it is better to collect the 8 cyl. engine questions. First, I found there is great lack of 8 cyl information in the manual. Yesterday we tried these settings on our 8 cyl MB engine but the spark was still missing. Our last try was trigger tooth 0 and trigger angle 66 deg. We use 1.8T VAG smart coills paired according the showed above example but with the MB firing order and the setting is for coils with built in amplifier. The paired cylinders are 360 deg away. The scope showed good clear trace with good missing tooth gap.
So, please,, we need advice or setting samples of:
1. How to set vag smart coils for 8 cyl engines?
2. How to wire and set 8 injectors?
3. Do we need synch sensor/signal?
........all else you could imagine that would help for the first start
Thanks!

If your firing order is 1-5-4-8-6-3-7-2 you need connect the coils as follow

1 with 6
5 with 3
4 with 7
8 with 2

For VAG coils connected in pairs you need for each pair a pullup resistor (to +12) about 1K
However I suggest to use OEM passive coils instead of VAG coils.

The same with the injectors. You need to connect them in the same way as injectors.

Only crank sensor is required.

Hello Jadzwin,
Endless thanks for your support. Just two more things:
- please, can you provide simple el. schematics/drawing how to wire the 1K pullup to the +12V when VAG smart cois are paired? I just don't want to mess up the things. These coils are so popular these days so it would be of great help for anyone using them. (The OEM coils were not available with the engine)
- in the injector settings I can see only 6 inj phases. How to relate these to the 8 ign. events? I.e. 4 inj.pairs(phases) to 8 ign.events? Do I need to check "squirt twice per cycle" box? Our injectors are paired just as the coils are.
Thanks again!

[Jadzwin]

Here is how the pullup should be connected:



For wasted spark and paired injectors you can use sqirt twice per cycle, so each injector will provide fuel at every engine revolution

[vagman]

Nice! Thanks!
So, if we take the firing order 1-5-4-8-6-3-7-2 and the coil and injector pairing is:
1 with 6
5 with 3
4 with 7
8 with 2

How would look like the inj. phase table?
-Like that?

[vagman]

Anyone? Please...

[pepifebles]

Hi, My wiring its almost finished. This week try start the engine. It's possible get base map?

[pepifebles]

Finally anybody have base map for this engine?

[pepifebles]

Hi Jadzwin, my injectors and coils wiring are finished. Could you tell me how connect crank sensor and throttle body?

[SUKHOI]

Are you using stock harness or making your new harness?

[pepifebles]

I'm making my harness. Throttle body, crank sensor and knock, each have 3 wires

Strange, it looks very hard getting support on this forum. Not to mention the connection problems we had. So far 2 emails were sent to Jakub and 2 times asked here about simple thing! - injector phasing table on a V8. I start to think it was great mistake buying a market newcomer. Sad...

[pepifebles]

It is normal. we are many asking for help at a time and they are very few. This is relatively new and is what you have. I am confident that eventually we all benefit. We have to be patient.

I find the support here is the very best you can get, especially when you have very little knowledge. The problems of some users must be very stressful for Kuba and his team. Some users know nothing and just want to install the system and map it without any previous knowledge. Every day new features are required.
I find the ecumaster team is doing a very good job. It is important to set the priorities correctly. No other software company is known to me who so quickly responded to requests for changes.
Except maybe Autotune.

[pepifebles]

+1. Completely agree. Normally other company tell you that asking to your local dealer. Here they answer practically all. This is the reason that I Say we have to be patient.

There primary job is to support dealers but still they help and support as many others as they can!
None of my hundreds of customers has ever had to contact EcuMaster, they contact us and we fix it. Have you even tried to contact your local dealer?

[Welshman]

bare in mind as more people use the ecu and become familiar then more people can give advise and support can only get better
