Nope. 12V_MREL is on in all three states. To archive this you need 12V_KEY to be connected to IGN-1 on picture above.JRD McLAREN wrote: ↑Tue Jan 11, 2022 5:28 pm.. I'm assume:
12V_MREL ON - stopped engine
12V_MREL OFF - cranking
12V_MREL ON - run / idling
RIGHT .. ?

Re: microRusEFI
YES, you right ...
my meaning is wrong ... sorry for effort ...
Some cars have two 15 lines (15 and 15A) form ignition switch ..
and some has "main relay" for whole electricity in the car - drive by ECU PCM or PMU

Re: microRusEFI
...picked from SLACK ...
Automotive companies avoid to use small (tiny) SMD components
smallest smd (0402) can be shorted by humidity sooner ... as bigger 1206 ...
I have same old ecus ..and the smallest one are 0603 ... 0805 is standard ...
"bigger" caps are 1206 ... etc ..
(many OEM ecus has no protective film / paint / glaze)
Will be good to use "automotive grade" passives for the future.
C0603C104K3RACAUTO - for explame
..and on the other side ...
avoid to use "BIG electrolytic CAPs" ... it can be broken by vibration ..
(it is glued if it is necessary)

Re: microRusEFI
Pic of Ford or Hyundai not sure which one probably Hyundai
R22 is probably 1206?
I think I see at least caps smaller than 0603. Four sizes on the same board a bit insane.

Re: microRusEFI
Hi guys,
just looking through MRE. Looks really nice for 4-cyl applications.
You decided to use TLE8888 for it.
Did you find a reliable distributor for the procurement of this chip?
I only found Digikey, who seem to be willing to sell small numbers of it.
Is there any other second source?
kr, sepp2gl

Re: microRusEFI
It was designed before the chip shortage
yes magic part dependency was a risk then and is a bigger risk now

Re: microRusEFI
this is probably offtopic here
nothing particular. just saw a usb connector, which reminded me of some pronounced ideas of moving to can bootloader (still under construction?)
besides, when recently my brother was chip-tuning his diesel citroen, the garage guy soldered some wires to the ecu directly. he said he could flash it through a normal diagnostics connector, but in that case he won't be able to make a backup.
K-line or LIN might be too slow for this purpose, but the bandwith of CAN (a second one?) should be enough. However, with TunerStudio supporting only serial connection, there isn't much value in all this...

Re: microRusEFI
Just a reminder that we have a working prototype of CAN-to-serial-to-TunerStudio bridge just need to figure out if there are defects there or not.

Re: microRusEFI
these parts have pretty similar specs why do they even have two different parts? is that a trade off between speed and resistance or something else?

Re: microRusEFI
Different rdson resistance. Pick the lowest one since it makes less heat while on.

Re: microRusEFI
where do I read more about that CAN-to-serial-to-TunerStudio bridge? If it works fine, it might be a good idea to implement it on board, so that the ecu can be completely sealed?

Re: microRusEFI
GD32F405 GD32F4 experiment failed: have a discovery board with GD32F405 - while openocd have successfully flashed rusEFI and st-link equally happy connects to this chip I do not even have LEDs blinking. Experiment goes on the shelf since zero priority.

Re: microRusEFI
Now shipping microRusEFI 0.6.0 with on-board SD card.
For the last two months we were experimenting with $299 pricing at https://shop.rusefi.com/ but it gets back to $450 on Aug 15th.
