Introduction

Post by Bartman »

Hello all,

I'll try to be short, I can be long winded. I have owned a shop for nearly 30 years and I am also an industrial controls engineer. I have used aftermarket ECU's that were pre-programmed such as FAST. In my controls background I have done programming in many types of distributive control systems and PLC's. I am working on a project and would like to use a BMW V12 either a M70 or M73. The decision between those 2 will likely be base on price and condition is my area. Any early advise? I'm starting from scratch, I don't even know what to use to communicate or program the RUSefi.

Thanks

Welcome!

https://rusefi.com/ is the starting point of anything related to rusEFI

https://rusefi.com/ has a link to https://github.com/rusefi/rusefi/wiki which has a link to https://github.com/rusefi/rusefi/wiki/HOWTO-quick-start

https://github.com/rusefi/rusefi/wiki/HOWTO-quick-start has a link to tuning software we use

There is a chance that we need to make the website less confusing :(

Hello Guys and happy new year 2022!
I think, it was a perfect idea of Bartman to create this intro-thread recently.
So I can just append my introduction as a newbe in this forum, which I discovered by chance just yesterday.
I am a retired automotive engineer. My professional background through most the years was more or less about all aspects of combustion engine control (both diesel and gasoline).
So from time to time I wander through the web to find out, what is going on on the DIY scene. And so I did yesterday.
There are always some interesting discussions and topics, where I might be able to help.

Welcome to the forum! Do you have any DIY EFI projects/test mules in mind?

Also some activity happens on Slack chat https://rusefi.com/forum/viewtopic.php?f=13&t=1198

...not really.
I didn't follow DiyEFI frequently during the last 10 years...
What is a "Slack Channel"?
Why should I join there?

Hi!

Slack is a tool for quick communication thats built with "channels" to focus conversation. Think of it as the messaging App for development, problem solving, and instant communication.

I highly recommend checking it out

...thx for clarification.
I will do.

Maybe I misunderstood AndreyB's question about my own DIYEFI project.
I falsely related it to DiyEFI-forum of Fred Cooke (FreeEMS).
Actually I intended to operate my Honda-motorcycle CB750K, a 4-cyl. 750ccm by a DIY-electronic.
Purpose1: MAP-based ignition, synching the carbs by steppers based on 4(!) MAP-sensors, Idle-speed control with stepper
Purpose2: Ignition as above, replacement of the carbs by an EFI; I already procured throttle-bodies with injectors and TPS years ago.

Purpose2 is highly ambitious (even with my background) because it will need an official release from german TÜV.
With Purpose1 I made an electronis based on Arduino for the synching and I am in the process of mounting it to the CB750K.

But my main purpose to join here is to consult and advice.
I joined engine development as an electronics engineer in 1983 and kept it until my retirement.
There is plenty of experience to share.

I would love to only need 4 :)

I feel bad for you having TUV so, I guess given the choice of TUV looking over my shoulder or 12 MAP sensors I'll take the 12 MAPs :)

I guess 4 is plenty when you ONLY have 4 cylinders ;)

Seriously though, very nice. It is good to see another sole who believes every cylinder needs its own MAP sensor.

Mine is here:

Congrats!
"Is there life without a Ferrari? Yes, but it doesn't make any sense." :D
I guess you gave your life quite some sense.

Did you tell your left cylinder-bank to stop smoking?
What was the reason? Cylinder-head gasket?

Thanks. yes its got head gasket problems....I'll update the thread this weekend once I know if a re-torque fixed it or I need to pull the engine anmd replace them. Teething issue

I'm just kind of chuckling seeing your setup as it appears we both saw the same issue, then went in opposite directions to try to fix it. I'm a mechanical guy and chose an ECU fix, you're an ECU guy and chose a more mechanical fix. This makes me suspect its a more difficult problem than either of us are admitting to yourselves. :?

Ciao!
Like always the truth is somewhere in-between.

What is the intent for your 12-channel pressure aquisition? Why are you doing it?

Same main reason you're doing 4 channel I'm guessing. I use it to to show me what needs adjustment. I have a display that shows % error relative to the TB the actuator is connected to, this make physically adjusting them easier (each has an adjusting screw just like your honda carbs). Then the ECU calculates global fuel based on average MAP but uses the cylinder signals to adjust fuel up or down in each cylinder to get a good mixture regardless of how well the TB are physically adjusted....so I am doing kind or the opposite of what it appears you are doing with you computer making on the fly physical adjustments, I'm making fuel trim adjustments to avoid needing better physical adjustment.

is this "introduction" still? is there a better topic to discuss this? if that's chatting maybe Slack would be better for chatting? if that's a discussion of something specific maybe it's time for a specific forum post?

Nope...You are perfectly right.
I propose to move this exchange into ./User Support/You and your Build/"Multi-Throttle Arragements" as new tread.

But...
...I also propose to make "Introduction" an own chapter of ./User Support.
This is the entry door for each and every NewBe into the board (at least it should be).

We recently had a chance to forum structure and at this point I am not open to think about this, forum would have to stay as is for some time. At the moment I am overloaded with existing ideas and commitments, in light of this new proposals are often hurting not helping.
