Speeduino DIY standalone EFI (M60 V8 content)

[Northern]

Some Questions after I read that 10 kilometer long forum that Pazi wrote above (its quite confusing because 1000 different things are discussed in one...)

1. I read about Teensy 4.1 is 1000 times faster than 2560. Can I use that for Pazi88 M60 Speedunio?
2. Injection is only with 4 channels but I read about 8 direct controlled injectors. Is that possible with Pazi and Teensy 4.1? I dont want to squirt 1 out of 2 times against a closed valve
3. With Pazi standard components is it possible to go directly with the standard BMW ingnition coils?
4. I hate soldering (because I am not good in it) so to avoid stupid mistakes can i buy Pazis board somehow tested and completly finished?

I have good basic understanding in electronics but no experice with arduino or similar... If you help me I promis i will create a Documentation for dumb guys (like me) that everybody can do it afterwards by his own. First without turbo/compressor, later I will add that :)

Thanks

1. Pasi was going through his Speeduino boards and slowly updating them to use Teensy but I don't think he updated the M60 board. (Teensy uses 3.3V instead of 5V so stuff needs to be added to allow the car's 5V sensors to be used).
   He now makes an STM32 processor board that is a direct replacement for the old arduino in the speeduino PNP board
2. Not sure, might depend on the PNP board
3. That is how it is intended to work, but you can modify to use others.
4. Currently no, unless you find someone else willing to do it.

And one more thing.... Pazi you have a VNLD5090TR-E on your List. It's not available anywhere.... is there an other way? It looks like just a protection, the VNL5090N3TR does the same and has almost the same spec. but the pinout is different and there is no status check and only one channel. looks like a global problem so we need a solution there otherwise nobody can assemble your board

I'm surprised that that is the only availability issue right now given the current shortage.

I will like to ask if this speeduino will work on m62 or m62tu engine? I have one of m62b35 and another it is m62tu b44
but want the speeduino for m62b35.

Check the harness pinouts in the ETMs of the M60B40 and M62B35.
Harness is likely different, connector may have a different socket, some sensors are likely different.
You might need to repin the harness at minimum, maybe convert to an M60 harness (if that is possible like the 24v engines?)

Hi everybody

I love that Project! And I work at a very similar thing at the moment. Engine is a M60B40 (with body of B44 and steel sleeves with 92outer diameter and 89 bore so its again a M60B40 but ready to turbo oder supercharge). 50% of the mechanical stuff is done so its time to take care about electronics....

I'm glad to see open source alternatives to MS are easily available now, I'm looking forward to the day when I get to tune one of these for someone. Still haven't seen any cars running RusEFI in person.

In my speeduino PnP design I use ISL9V series ignition drivers. Those work great and can drive stock bmw coils easily. Even the mighty IGN-1 coils are not problem for those.

[bmwman91]

Wow, I am very impressed. This is a super cool product and project. I remember when I first heard about Speeduino, I was pretty skeptical since the processor was much less capable than the one in MS3, at least on paper. It looks like there's more to things than clock speeds and core bits! Then again, the M42's all ran on 1MHz 8b 8051's to begin with, so this is a huge step up from that, and I'd imagine that it is also a faster setup than what most of the M5x engines ran on, too. I am super happy to see something other than Megasquirt coming together for the DIY community!

There are a lot of posts in that thread, and I was looking for ignition coil driver info. I gathered that the drivers for the factory "dumb" coils are on the custom mainboard...are you using BIP373's or similar?

[pazi88]

BTW I have designed speeduino PCB for those bosch motronic ecus that m60 also uses: https://speeduino.com/forum/viewtopic.php?f=16&t=2638

You can just assemble that inside stock m60 ecu case, use stock unmodified wiring harness and also use stock coils.

Okay, ordered a kit from Great Britain, found a real cheap m60b30 ecu online for use as a case, and ordered a set of ls1 coil packs on ebay. All in all, I am under $300 for enerything! What I like about Speeduino best is it has 4 output channels - Megasquirt 2 has only 2 (at twice the price).

Now I just have to build the ecu, and then go through the existing wire loom. This is a looooooong term project, so I am in no hurry. Just downloaded Tuner Studio and will install.

[M60b30twinturbo]

Thanks for your build info. I am working on a low compression M60b30 with n63 twin turbos, Ferrari 348 intake manifold, and solid lifters. The exhaust manifolds mostly bolt right up with only a few modifications. I am getting closer to the controls work, and luckily I found your post.

I was looking into Megasquirt and found that the Speeduino unit is only a fraction of the price. Your tuning info looks pretty straight forward, and I think I have the skills to complete my build. Thanks again for the great work and documentation.

PS - the engine is eventually going into a kit car as I have adapted a Porsche 997 tranny. I am also planning on adding an EV motor from a 760, and I just need to get it calibrated. Too much fun!

Nice. I did that on my Datsun 620--chop chop and hardwired Speedy into the loom, then removed the extra wires

[Mykk540i/6]

I ended up cheating and hard wiring the speeduino directly to the engine wiring harness. It is totally possible to maintain the 88pin connector if desired. I just didn't see a need to

[eduTechnic]

Very cool build man! I'm just getting started with Speeduino on my Datsun 620. I have better plans with the e34 for Speedy as well. Can you toss up a pic of how you went from the back of the stock DME connector to the 40-pin Speedy connector? I've got a bunch of Dupont cables but they're so thin.

Nice to see the DIY EFI stuff is running now - kindof funny that it uses msq files, but hey, if it works, it works!

Great looking build too. how do you like the DIY EFI?

[Northern]

This is really cool. Thanks for taking the time to document it so well!
