(it works on EGT also ... AD595)

...cause .. this is the cheapest Lambda display ... https://www.ebay.co.uk/itm/263849308282?hash=item3d6ea4f07a:g:HPoAAOSw0xhg5vGj

.. if we can have programed Out ... 1V = Lambda 1

..and two outs are planed for 0-5V OUT and 0-1V OUT
a.k.a. Lambda out .. ??- 1Volt = Lambda 1 (0.85V = 0.85Lam)
..or Narowband output ..?

..some stickers or flyers .. ??

...so .. car have flywheel form Renault 5 Turbo ..
and it looks like Renix 44-2-2 .. https://github.com/rusefi/rusefi/wiki/All-Supported-Triggers#renix-4422

No ..
it was 5 ..but it is not here ...

So, new build / project started. It is not my car, but I must start it. .... :mrgreen: Engine is Alpine 1.4 liter with turbo ... all wires and sensors must be produced and mounted. I have no idea, what kind of trigger wheel will be used .. ..full seq or pair ... "how to wire" ETB .. differ...

Bosch trims the sensor element itself on the LSU ADV. It works the same way, except there's no extra external (in the connector) resistor paralleled with the sense resistor inside the controller.

OK ..
precise laser cutter can do this job ....
..and the we can have same sensors ...

Do we know pinout of this sensor or is it obvious from wire colors?

Yes, it the same as LSU 4.2 / 4.9 has ...
..
but I have no idea, "how labmda controller" measure sensors parameters without Rcal ..

Flash memory is not used .. why? maybe proper route is to fix this defect in the code? btw we made the explicit choice to not support multiple devices per bus to avoid any priority inversion due to locking of the shared resource When I'm testing my addon borad, EGT and SDcard woks together on SPI3 b...

special edition of PCBs arrived ..

I have 20220126 .. and it have EGT option ..

EDITED: but I can't test it at this moment ...

..in latest firmware ... ???

this is for microRusEFI ... not for others ...

Free or Paid version of Tunerstudio ..??

Free version has disabled 3DView ...

..so 10 pcs mcu from china is here ..
and it looks like genuine ... ..now I waiting for PCB ...

Me ...

I'm found last 6 pcs of 072CBT, and now is gone ..

..5 was ordered via ebay, and I'm so curious for it ...
(what kind of FAKE it will be)

Small update ...

Mounting on "MRE + SD Card" version is soo easy ..
Just pick it into the MRE board and connect / solder two wires for CAN.

Oh .. sorry for my inaccuracy ...

It is SD card log .. one from stable 20220126 -without "green TPS line "
another is from previous snapshot .. with TPS

one from SD card another from TunerStudio

it can be different .. ?? I'm never try this before ...

I can adjust some values, but when I'm open log file, I cant see TPS values, VSS is wrong also ... maybe RPM ... (I'm rev my engine to 8t, but half values are in log file) log are onlie.... https://rusefi.com/online/view.php?log=685 https://rusefi.com/online/view.php?log=686 EIDTED: VSS must be set ...

I'm got this error .... chsys.err.png it occur when EGT chip SPI & CS pin are selected, no sensor connected (to MAX31855) and MRE is conected, or to be connected to TS (via USB or BT) MRE drop to FATAL, and engine STOP ... (it is not too safe, when you overtake and something cut EGT senror wire)

We can try tune idle ...
and I have no idea, how MRE initialize idle stepper ..

It must be:
FULL OPEN ..and then almost close ..
or opposite ...
FULL CLOSE and then open little bit ..
??

or this .. ( )

try this ...

Mmm... I'm found this thread this evening .. (too late) ... If we have siamese intake ports, we need full sequential mode .. (two injectors on a 4cyl engine with 2 intake ports) ... 1st injector for 1 & 2 2nd injector for 4 & 3 for 1-3-4-2 firing order This is the best setup for this ... ..t...

and I have completed first series MRE with micro SDcard ...

two can be sold ... immediately

two new solder pads for Crank HALL selector ...
it is easiest for users, than solder 0603 smd resistors

I'm not sure ... maybe NOT ..
I don't have any "free" HC05 at this moment ..

that's true ...U1A U1D (and .. ?)

I have linux ... picocom minicom or CuteCom ...

try to connect RX TX GND, run terminal ... and then connect VCC ...
you should see "+READY" message .. or "+OK"
