Thanks, My objective is to prepare sort of 'test bench engine' for my research group, where we can test and validate different parameter estimaton and control algorithm (its yet a long way to go with many unanswered things, but its on the move). Next steps (please correct me if i am neglecting somet...

Hello, A bit late, but i stuck in searching 36/2 trigger wheel from local scrap house and then executing the modification. New trigger wheel is now installed on the engine. I have included images step-by-step and engine is now running without trigger error. So, eventually ..... trigger is no longer ...

I am working in both directions, troubleshooting and installing an additional crankshaft position sensor (36-2 trigger wheel with VR sensor). I shall hopefully post an update here.

Thanks, rusEFI platform, once working, shall solve many of our issues regarding experimental validation and acquisition. Credit goes to the core team. On the test bench, there is lot to be done yet. Packing the wires and labeling the connectors, and perhaps installing a new crankshaft position senso...

Hello, A bit late response, once engine revolved ...... I took a day off. rusEFI frankenso rev 0.4 is now revolving the engine at idle. Here is a 40sec video of the engine, https://youtu.be/u_odg8fPzLI As i shared earlier, engine is not in the vehicle. My objective is sort of a test bench where diff...

definitely, i shall clean it a bit today ....... and will make some pictures and video.
will start tuning and developing the look up tables in a couple of days,

Engine started, idle for 20seconds.

hello, The trick worked, from youtube i confirmed that the mark on the pulley which i attached in previous response is correct one. Coils rcv 12V pulse (adjusted from the jumpers on rusEFI frankenso board), i dicsonnected CYL1 ignition coil from the connector and connected 12V 1.5W LED. TDC detected...

Thanks,
What if i take ignition pulse from ECU,
disconnect ignition coil, connect an LED/Light to it and put it at the dot on the pulley (in the image attached),

Maximum error would be equal to dwell time or less?
Am i right, or am i overlooking something? Please correct .....

hello, For TDC detection, I am searching for some alternative to timing gun .... bad-luck, Please confirm that my understanding is right, Once i have some mechanism wokring, i need to tune 'trigger delay' to attain the TDC at ignition time? Is that right? Please correct me if wrong, Apart from it, i...

Removed the plugs, furthermore i checked out every thing a to z, starter relay output contact was giving some noise at ohm meter, relay is now replaced. Trigger decoding is now fine (please correct me if my interpretation is mistaken), i rcvd the following output: 2021-04-25_14_58_32_299: EngineStat...

Now its fault on my side, i should have done it earlier
Battery will also run longer under low load conditions.............
thanks.

Battery is now drained, let me recharge it ........... meanwhile i shall have a thorough go through once again from all the observation i can get.
Thanks for prompt response all the time.

I think wire polarity is all fine, because upon swapping the wires once again ............ RPM is not detected again and stays at zero. Message output after I swap the crankshaft VR wires 2021-04-25_08_58_32_502: EngineState: TRG duty 0.000000000 486059192 2021-04-25_08_58_32_502: EngineState: TRG r...

I have updated the firmware, TS configuration is also updated using ini file in the new build. 'higher RPM' than expected is still persistent. Following is the output 2021-04-25_08_31_57_453: EngineState: TRG rpm=1458 time=497 index=0: gap=1.021 expected from 0.450 to 0.750 error=Yes 2021-04-25_08_3...

Sorry for inconvenience,
Earlier I donwloaded the rusEFI bundle for console, hex/bin file, and ini file.

How do it get updated firmware? Is there a specific download page etc, (regrets if my question is a bit odd)?

is it the link i should share?

I have posted the currentTune file at rusefi online,
Yes, 'use only rising edge' and ''display only interesting' both fields are already set 'true'.

Meanwhile, thanks for prompt response ......

Regrets, i overlooked checking the verbose output, it is here: 2021-04-25_07_14_01_163: EngineState: index=0 NaN gap 2021-04-25_07_14_01_163: EngineState: TRG rpm=0 time=42 index=0: gap=2147483647.647 expected from 0.375 to 0.625 error=No 2021-04-25_07_14_01_178: EngineState: index=1 NaN gap 2021-04...

For posting the tune online: right i shall post right after this reply. For verbose output, I tried in dev console and got the following output 2021-04-25_06_23_04_329: EngineState: TRG rpm=0 time=1127 index=0: gap=290.835 expected from 0.375 to 0.625 error=No 2021-04-25_06_23_04_329: EngineState: T...

Hello again, Thanks for a prompt response. 1) With the help of the example you quoted, i configured the build as '4 stroke without cam sensor', in dev console i receive trigger signal as expected but its not decoding the RPM. RPM field stays at zero. I have attached the figure from dev console(trigg...

Hello Everyone, rusEFI has become such a nice community. I do research kind of stuff on engines. Until my work was limited to engine dynamic modeling, model tuning and validation, I had data acquisition setup on an engine running with OEM ECU. I was able to acquire all the engine inputs and outputs....
