Hello, I think only using a clampmeter and a piezoelectric accelerometer connected to the supply of injector you can see the delay of opening moments with a scope,but you must spend some time with setup and positon of sensor for this. I will attch a file for this(image was captured on LC120 with a k...

I don't know if I can post wiring diagrams in here... It will be easier to explain. But, from the wiring diagram that I have seen, you have 3 feed wires and 7 ground wires to the ECU. E22, A31, B1, B8, B17, A21 and A30 are all ground pins on the ECU. E1 is a feed wire on the ECU, always hot. E2 is ...

Hello, Today I made new recordings with some amendments: -supply from main relay and ground to ECU was doubled -the voltage was captured at ECU side(using backing pins) -can't record the ignition primary current(every spark plug coil have his own amplifier)/this is the reason why I record ignition f...

Hello, Thank you for your answer. My question was why the same battery tested with the same hardware give different results(and diferrence is a big one). I am sure about the initial value of voltage because I measured 12,7 v with Fluke 233. I can't be sure about the standard of battery(is a Duracell...

I have added a 30hz Lowpass filter to you Green Channel (ECU Current) and added a RPM Math channel to try and paint a clearer picture. Victor Delete.jpg It appears that he ECU stops consuming current before the RPM drops ?? Add to that your suspicions that it is not drawing enough current to proper...

Hello, You can record in the intake/crankcase/exhaust pressure waveform at the same time with cylinder pressure? Maybe there is the answer for your question. :roll: Your engine have oil consumption(you can see this using an endoscope)?Only a liquid(oil in this case) pumpimg in cylinder will give to...

Hello, The same battery was tested by dealer and the result was 873 CCA ...in 30.09.2016 at 17*C. I think it was used a Midtronics tester. 145% and 117% was the results using Pico Diagnostics compared to 102%. I think you must recheck the math behind of Battery test.The test must check the initial v...

Hello,
ECU was faulty.
Thank you for your support.

Hello, I ordered a new crankshaft sensor. Today I made some new measurements:the ECU current and the SIL(K-line) voltage. I think is a strange to see ECU what need 2-3A only with ignition ON(not supply injectors or other sensors/actuators-MAF,injectors,VVT).Only air/fuel sensors preheaters can use t...
