[@wackydriver]

This is cool, thanks for your open-source contributions. Technically speaking I could also make it work with your older BMW PnP boards? I have one of yours for M42, it works flawlessly, but it would be cool to also have CAN bus in E30 (with Gauge S) :)

[@pazi88]

It should work just fine on any speeduino v0.4 based board.

[@Pedro-ke6xp]

Thank you very much for your work! This is awesome! Could this new chip allow us to have more inputs and outputs?(soldering new connectors) On old boards? Or we would need a whole new ecu to take advantage of the higher i/o of the stm32 chip?

[@pazi88]

The number of IO has never really been a problem. Even the Arduino Mega has way more IO than you need. The Speeduino boards just don't utilize those well (and earlier there really weren't features that would have benefitted from that). So not even half of the IO is actually being used. I have designed my newer boards to have more IO than other Speeduino boards have to be able to use the new features easily. Problem in Arduino Mega has been lack of timers to do more than 4-cyl full sequential, but this board solves that problem. And also the Mega doesn't have enough external interrupt enabled pins to be able to use all features that require those. Like VSS, dual CL VVT, flexfuel etc. But this board solves that too.

Nice work 👍👍👍

[@rsxjackal]

Thank you for your amazing work, keep it up! Also i have a question, will we be able to setup basic traction control (i.e. rear wheels speed > front wheels speed or external signal to lower engine power)? I have an a idea to use BMW's DSC mk60 (it's kinda standalone for ABS) on my E30 and it would be great to read signal from DSC to ECU that it should reduce engine power to gain traction, it's might be hard to implement on cable-driven throttle body, but i should get away with spark and injection cut.

[@AXJoFE]

I have the PNP Ecu for the m52/tu from DIY-EFI, can i replace that main board to this STM32 version?

[@pazi88]

Unfortunately no. It doesn't use the standard Arduino Mega board, but the Core4. So this doesn't fit that.

[@BMWE30RESTORATION]

very interesting, I'm currently soldering ms 41 rev2.0, after that I'll try to order this board on psb. After installing it, do the jumpers need to be disconnected for bath fire and wasted spark?

[@pazi88]

The jumpers between wasted spark/sequential and for injection too were on the rev2.0 because of the speeduino FW limitations at the time. With current FW versions, you can leave those open and assemble the board with 6-cyl sequential fuel and spark. Then run the custom 6-cyl sequential injection FW in the Mega and use wasted COP mode for coils and it will work. And if you later upgrade to this processor, you can just switch to sequential ignition in TS.

Hi. I’m interested in using this with an NO2C board to improve stability with a dash screen (mega has slow refresh & crashes). But I use modified firmware to get 4 channel injection (sequential). Is it possible to upload custom firmware or do you modify the speeduino firmware to work with your custom board?

[@pazi88]

Yes, should work fine.

[@evanleonardomirandacruz6031]

Would you mind to explain to me why it allows the original speeduino to run up to 4 extra cylinders? I'm new in this learning field and I'd like to know more about mods for these chip Ecu's

[@pazi88]

In speeduino the Arduino Mega only has 9-timer channels left for inj/ign outputs. So it can run up to 4-cyl as fully sequential. But with this, there is plenty of timer channels to run 8-cyl as fully sequential. Or even 12-cyl with some code changes.

[@潤武井]

I am using STM32_mega for a motorcycle ECU with a Ducati engine. I am not using it on a real car yet, but it is working fine on an engine emulator. There is a discussion about "SD logging" on the Speeduino forum "STM32 development". I have a few questions. 1. What exactly does it mean that SD logging is experimental? Does it mean that SPI mode is used for data transfer? 2. Why is the SD logging menu disabled? 3. How can I get SD logging? Any information would be appreciated.

[@pazi88]

It was experimental at first, because it was working for me only and no knowledge thst does it work for others. But AFAIK, it works fine currently. Change the MCU to STM32 in the project config in TunerStudio and it should be enabled then.

[@潤武井]

@@pazi88 Thank you for your reply. I understand that it should work. I think there may be a problem with my hardware or software. Thank you for this project.
