Here's the drawing for the 3rd connector type (1473244-1 + 1746979-1):

The third option for 81-pin female connector is TE 1473244-1: 81pin-female-connector-TE-1473244-1.jpg AKA "Komatsu PC200-8", "60D98D", "60D/98D", "3601115-98D-60D". It's more like "german" type (368376-1) and doesn't fit the "asian" male pc...

please, show us the enclosure! ;) There're several options. First, ME7.8.8 enclosure with 81-pin connector: enclosure_me788.jpg It's compact, cheap and can be waterproof sealed. Here's an example of OEM sealant: enclosure_me788_oem_sealed.jpg Another option is Bosch M7.9.7 enclosure with 121-pin co...

The assembly process is very simple, only through-hole headers and modules:
Now it's ready for testing:

Итак, чтобы двигаться дальше в изысканиях с ion sense, нужно продолжить работы над нашим новым ЭБУ на базе rusEFI, которое будет способно делать программный процессинг аналоговых сигналов в реальном времени. В этой ветке есть несколько фотографий плат: https://rusefi.com/forum/viewtopic.php?f=4&...

It is rumoured that a new interesting rusEFI ECU is coming...
More info to follow soon...

But we have to wait for cam sync to begin fuel and spark or does it switch to crank sync? In fast spin-up mode, we wait for crank sync. Ignition/injection will start right after the first sync point of the primary trigger. Please be aware that this mode works only for certain trigger types (e.g. 60...

I have read some lines about rusefi having fast start features
Can we switch to wasted spark and batch fuel during cranking?

Yes, that's true. If you enable this option, it will use batch fuel/wasted spark right after the first sync (until fully synced):

Hello and thank you for your interest in Prometheus!

You may use this excel file as a starting point for DigiKey BOM: it has most of DigiKey part numbers filled in (except for small passives):

Был произведен первый запуск двигателя "Рыжика" на новом ЭБУ Deucalion: https://www.youtube.com/watch?v=-Vm4fQnetag В целом, плата оказалась рабочей, но по части обработки триггера нужно ещё постараться, пока что планка гистерезиса фиксированная, а нужно попробовать сделать адаптивную. Так...

Now we have the real first pressure sensor + ion sense data on running engine! 8-) https://www.youtube.com/watch?v=JeyfxoiJhus The engine was idling at ~1200-1300 RPM with the short throttle acceleration up to 3000 RPM. Here's the saved oscilloscope waveform for those playing at home: running_pressu...

PN is 03L905061F see more info right above :) Here's our first real data from the pressure sensor installed in a car, cranking (no combustion), 3rd cylinder: pressure04.JPG If we measure the peak pressure moment, we get 208ms for 252ms period, it's 360*208/252 = 297 degrees from the sync. point, or ...

I've seen a video on youtube, tell us more! Also, let's clarify that stm32 is now what, optional?! And Kinetis alone is capable of running limited? not limited? rusEfi? https://www.youtube.com/watch?v=-Vm4fQnetag Yes, some progress has been made! :roll: You're right, this board config does have som...

Maybe we have the first video of the sensor output?

** Part II ** Now we have the analytical transfer function defined and we want to find the best PID controller coefficients for it. But first we need to define "The best". There are two types of controllers: 1) "Servo", the set-point is ever-changing and the controller changes t...

Let me try to explain the main idea behind this autotune method. ** Part I ** Let's assume that we want to find some working PID coefficients for a real device ("plant"). I'll use @Russian's Miata alternator as an example. The plant has an input (the PWM signal which controls the alternato...

I believe our issue is with the TPIC8101

Oh, that's unfortunate, as there's actually TPIC8101 on Prometheus:

.. on stopped engine, or when the ignition is powered on (and engine is stopped) .. Right ..??

The option is called "Use fixed baro corr from MAP".

Is it normal that it will not respond for the first request? Here's the "normal" behavior of HIP9011 on Prometheus board (no XTAL issues whatsoever): enabled=Yes state=1 bore=87.50mm freq=6.54kHz PaSDO=6 band_index=39 gain 1.00/index=-1 output=PC0 integrator index=-1 knockVThreshold=4.00 ...

without complex piping your only sensing the MAP on one throttle and that fluctuates badly. 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=...

So with ITBs this getTpsEnrichment will not wok, since between two engine cycles i will never have a tps movement that bit to detect it rusEFI firmware works with ITBs just fine, including speed-density and TPS-TPS enrichment. Have you tried setting "Fraction Period" and "Fraction Di...

The idea behind KE1xF Kinetis in Deucalion is a combination of several features: 1) 5V-compatible inputs/outputs; 2) High-speed 168 MHz clock - so we have STM32F4-comparable performance guaranteed (most other 5V NXP chips have lesser freq); 3) 3x high-speed hardware analog comparators + 3x ADCs - ve...

What exactly makes MKE1xF special? What does S32K148 not have what MKE1xF has?

HS-mode 168 MHz, which is preferable for realtime multichannel analog signal processing (trigger + knock/ion sense).

Can anybody post me, "any range" of working UA and UR values..?? 4.2: EngineState: cj125: state=5 diag=0xFF (vUa=2.119 vUr=0.916) (vUaCal=1.501 vUrCal=0.909) EngineState: cj settings: offset=0 P=0.02441 I=0.00762 D=0.00000 dT=1 EngineState: cj status: value=0.53 input=0.90/target=0.91 iTe...

autotune is trying to catch the correct values. Autotune in TunerStudio often tends to "saturate", when there's a big difference between actual and target values. So I'd recommend to restart it more often. If you see that Autotune has stopped responding and cannot change the VE values any...

How did you managed it? AlphaN algo ?

Speed density + TPS-based VE table + TPS-based advance table. But it also worked with pure speed density, just not as good as with hybrid MAP+TPS-based setup. As for the MAP, I've enabled option "Use minimal value of = 4" (for 4-cyl).
