Lol ! I look like a teenager ? I am 35, and I don't think I am quick. I just discovered the PCB tools.
I go to work but I can't see my friends because of lockdown So I have much time.

Re: [info] rusEfi Scheduler Performance & Accuracy
Okay :D Thanks, There is some H7 without dual core and with a lot of ram. I see that microrusefi come back from F7 to F4, i don't know why, but the ram is the same, so the frequency is certainly useless. The power of a stm looks completely crazy compared to others. And the frequency of an engine is ...

There isn't a lot of options with smt assembling :cry: :cry: I discovered that the 2 layers of the middle are only 0.5OZ, I will think different if I do others boards.

Re: [info] rusEfi Scheduler Performance & Accuracy
As interesting as it sounds, I have to agree with Andrey that it probably isn't feasible for us right now. The DMA controllers are already both quite loaded - 3 ADCs, UART, SPI (SD card logging!). I just don't think it's necessary. The jitter requirements of an engine are actually pretty generous. ...

Re: Full JLC PCB
I finally find the MAX31855 on JLC <3
It's a extended part, but look easy to install. There is a little place on the left of the stm.
Here it is.
I should have let more room for the mosfet... But some of them are for lights on dash

I see in the signature of "OrchardPerformance" that "Now keeping MRE and Proteus in stock in the UK, PM or slack for details."
Maybe you can see with him.

Re: microRusEFI
Hello,
I have an other question, I believe that I am right but not sure.
Does an AT input can detect ground contact ?
My clutch pedal goes to the ground, I just want to be sure if there is no risks. (maybe, must I plug a resistor before ? )
Thanks,

Re: FrankenFerrari - V12 Ferrari 308
If you want a 0-5v signal to dash, you have to use a high-side output. If you want to control the ground, you have to use a low-side output. The microrusefi, for exemple, allow a 12v output, on the high side via jumper, perfect for tacho out. image.png But you have to pay attention to the power, hig...

Re: Hello from my VW 1200
You can use one coil by cylinder and go wasted, no problem, some manufacturers are doing this with COP.
Have you a picture of what you are talking about for the sensor ? My english is very bad
If you put a sensor on the distributor, you can go full sequential.

The dificulty is to have a crank signal. You have to put a toothed wheel on your engine with a VR or Hall (or optical) sensor. I think that have been done a lot of times on VW 1200, and there is certainly kit. A fully prebuilt ditributorless kit already has all you need, with correct tune. With ruse...

Re: Full JLC PCB
Thanks !
I hadn't see the BTS3028, they look better and shorter.
The MR and AR, mean Main Relay (for fuel pump) and auxiliary relay (for fan relay).
It's design for relay, and I want them small.
The 100k is a protection for stm, just in case, as the relays are inductive.
Am I wrong ?

Thanks for the answers.
But... I have others questions
I see there is flashmemory on the MRE, I also see that it can be accessible by the rusefi plugin, but how can we activate the logs, is it automatic ? Can we choose what to log ?
And what happen when the memory is full ?
Thanks,
