updated 21.12.2021

- replaced D3 D4 D5 D6 on bottom side

VLND5090TR can be replaced with BM2LC120FJ-C or BM2LC105FJ-C
..
but 3A current only ...
..it is still enough, I hope ..

and I'm not sure for IPD30N06S2L-23
Vishay SQD30N05-20L -- LOOKS BETTER ???

Nice ...

VSS Tested and calibrated this friday ...
it works at 140kph with no issues ..
"no more space" to test it at 200
..or higher ...

6teeth and 0.54ratio (coef)

......., I will add a display to show the current values. ....

This is good Idea for the future ...
"Standard" 0-5V output will be welcome ... in my case ...
(and "1V" output also ... LAMBDA 1 = 1Volt)
(to use "standard Voltmeter" for lambda readings)

Processor ...

...taký lepší VEMS ...

It works well...

No modifications needed.
My VSS is Hall type 12V .. and works. (Grounding signal)
Signal wire is connected to 22- AN Temp4 directly without any pull-up/down resistor or divider.

EDIT:
...and 24 - AN Temp3 works too ...

OK ... I know all that things. ... but.. I have one cheap "chinese" tester, works good, and it has something UNF or NPT thread .. similar to metric M 10x1.0 ....presure sensor has M10x1.0 thread ... I can screw any M10x1.0 sensor to hose, use any kind of LOCTITE 243 glue ... a it has no pr...

GD32F190Cx .. looks good ...
except pins 35 and 36 ( PF6 PF7 )

(it will be a BIG problem, when one is connected to GND and other to VDD permanently .. )

I have a plain to use mck1117 firmware .. this one https://github.com/mck1117/wideband/blob/master/for_rusefi/wideband_image_with_bl.bin I'm not (good) programmer ... :roll: It's too hard to find some MCU everywhere .. SOLD OUT ... (corona crisis .. or what ... ) I have ordered last 6pcs of STM32F07...

new git repo:

new version for STM32F072C6Tx or STM32F103C6Tx MCU in LPFQ42
https://github.com/JRDMcLAREN/mre_addon_board_v2

and old one was renamed to:
https://github.com/JRDMcLAREN/mre_addon_board_v1

...buy any compression tester ..

..buy any pressure sensor ...
https://www.ebay.com/itm/265124922381

..and mount it together .. ??

I have one question .. about F103 wiring. ...

F072 and F103 in LQFP-48 has same pinouts ...

Has "planed" F103 LQFP-48 controller same wiring / MCU pinouts as F042 (F072) ..??

because I have these boards in production, ant it can be used for both MCUs

PCBs arrived ... and microSD card fit ..

version with STM32F072C8T6

(somebody must answer the question, "will it drift.?" )

OK..
but "my addon board is in progress" ...

I'm found some STM32F072CBT6 MCUs in LQFP48 ..
Will it work ..??

has CAN
instruction set M0

Well

still waiting for Godot ...

Thanks.

Is able make EGT option "visible" in any future release ..?

due to: https://rusefi.com/forum/viewtopic.php?p=43270#p43270

Added K-Thermocouple - MAX31855KASA

this is question for mck1117 ..?? maybe ...?

ESP32 or a BT module?

I have no problem make it for all ..
BT and ESP32 ...

I gave up on BT modules. Terribly unreliable.

It is depend on each module.
I have "original" HC-05, and it work fine. Many years in VEMS.
Some cheap "BEKEN" are crap, some are good. (firmware..?? )

another idea...

Thanks ...

I'm not sure, if it will fit into aluminum case, I have plastic one.
And Molex Microfit connector is not waterproof.
(it is not problem in my case)

Has anybody hint for small waterproof one ?

NOW .. on GITHUB ...

https://github.com/JRDMcLAREN/wideband_controller_mre

It started as a wideband controller form mck1117 on small board with 2x5 pin header, and headers for (rusefi) wideband module and ended as a compact addon board for microrusEFI. ..but due to lack of goods, and some kind of communication in this thread - https://rusefi.com/forum/viewtopic.php?f=4&...

1st - I have plan make any sample ..
2nd - OK you are so busy, it is not problem for me ..

Nice trip ...
