..try to disconnect RESET pin after power-up .. ..

So, just cut it ... and paste it to another one ..
( - - here - -)

somethink like "All about Knock detection" in MISC section ...

couple of concerncs: - you forget about 'knock windows' no "windows" is needed - are you sure about the accuracy of your measuring equipment/software? my "measuring equipment" can be my ears .. (or eyes) ...and "software" is my stupid brain ... there are other sources of noise in the engine. - YES ...

...cause ... It is knock noise - detonation On screen is FFT analyze .. "first half" is normal slow engine rev. form idle to redline.. "second half" is the same, but ignition is advanced (+10deg) .. and detonation occur.. .. this is the one of method to "detect" detonation.... and it is the "basic u...

.....Just like Frankenso, it has HARDWARE for knock but no SOFTWARE to detect or respond to knock. We have a problem here that... people enjoy creating boards while not much firmware progress is made :( VEMS have the same TPIC8101DW chip, but it can't 100% work for some engine. (it can't work for m...

The best way to do "the self learning ignition table" is measuring "in cylinder" pressure.
(we need to do measure and recognize unneeded spikes during "fire cycle")

Other ways are angular acceleration measurement and/or Ion-Sense.

What kind of detonation detection method you can use ..?? KNOCK Sensor ..? Ion Sense ... ?? or angular acceleration computing for the best torque ..?? I don't know if that question was for me, but currently it supports 2 knock sensors for detonation detection, just like the Frankenso. This question...

...how about implementing something really smart for rusEfi? Like spark self-tune or smth

What kind of detonation detection method you can use ..??
KNOCK Sensor ..?
Ion Sense ... ??

or angular acceleration computing for the best torque ..??

..Voltages are from "my" gui, it's UR and UA voltages ...
no VCC or SPI voltages ...

SPI works from 0.7V to VVC+0.3V ...
..if VCC = 5.0V , then HIGH level for SPI can be 5.3V maximum...

Here is some prinscreen of my IMF WBO2 control program ...
..see voltage levels ...

I'm so busy at this time ... and have no energy to test new firmware and CJ125 WBO2 controllers. (on frankenstein)

The actual problem "in my setup" is voltage readings "by rusefi" ..
I will it explain tomorrow ..

Oh, how hard is to be an idiot... Finaly, it works. Now I know, that if it is 301 marking on SMD resistor, double check it is not flipped 10E one...

Which one is it ..??

..I have some problem..maybe...

Same scenario as my ...

Heater PWN grow to 80%, and then you will see "overheating" message .. right ..?

so ... you need to have backup battery ...

and then try to run "cj125_calibrate" command in rusefi console on cold lsu sensor ...
..after successful calibration try to "run engine" .. and see whats happened ...

Yes

..engine must run ...

try to use simulator - https://rusefi.com/wiki/index.php?title ... re:User/en

Another "reverse engineering" of my second LSU controller.

No DIAHG and DIAHD are used, no divider for UA and UR.

..so ... Have working SPI communication ... Have working Heater PWM ... (it heat the sensor) (and FET also ... no fun :evil: - wrong design maybe??) Have correct output UA and UR voltages measured with DMM ... but not with ST / rusefi My discovery board have added backup battery. I don't know "how t...

Wow ...

So,I have no working CJ125 board with frankenstein .. .. (also)

I can do that next time I test it in car.

This is the gauges showing something at bench(No sensor connected).

You have any progress .. ??

Wow .. it's lively there ... So, I'm read last posts, and see video also ... and not so happy, with board failure ... In my opinion... russian has wrong / low / undersized starting battery .. (or wrong starter, or wrong starter wiring - high transient resistance) If battery voltage drops below 10V w...

OK .. OK ...

so get it back ...

Is CJ125 "onboard" palned ..??
..or not .. ??

(it is one of "standards" for me)

It's not that bad in rusEFI: 1) We have "MAP Sampling Start Angle" and "MAP Sampling Duration" - very powerful instrument; 2) We have nice and smooth MAP averaging (isMapAveragingEnabled=true by default); 3) We have "Measure Map Only In One Cylinder" and "Minimum MAP samples" settings - specially f...

.. I saw it somewhere ...

rusEFI can measure atmo pressure ... from MAP sensor ..
.. on stopped engine, or when the ignition is powered on (and engine is stopped) ..

Right ..??

If you need any kind of MAP sensor, then try to use "stock" automotive sensors ...

Any type from BOSCH or Delphi / Delco can be used. (from cars)

Ahoj ... Look at this: https://github.com/rusefi/rusefi/blob/master/hardware/CJ125_board/bosch_lsu49.pdf Screenshot_20190705_231940.png Ja tomu celemu chapem tak, ze chipaku bosch povies, ktory "amplifer factor" chces pouzit... a on potom na zaklade toho "upravi" vystupny signal ... teda nastavujes ...

...I will try to connect SPI as andrejka have it on the prometheus board ...

Ok ... let's move ... This is my current testing setup ... DSCN4860.JPG Orange, Brown, Red and yellow wires are for SPI Single Green is for heater .. Blue and (another) Green is power supply for CJ125 Board Grey and Black are UR and UA outputs. Single White connected to power board is for heater +12...

..I will post more details tomorrow..

..What's wrong with this board...
.. it lost SPI comunication, when +12V for heater is connected ...


Edited: .. on frankenstein ...
