Hello Henk and thank you for the feedback, it is much appreciated and a great theory too. What is interesting is the pulsations in the spill rail align just before the trough of the spill waveform! Again, more research required as any potential expansion of the spill hoses has been eliminated with ...
Hi Steve, Thanks for your thoughts, as you say, not really a "that must be it" explanation. A while after I posted the question it suddenly came to me that it could well be that what you see is a delayed pressure pulse after the injector fires. We have to take into account that the back leakage/cont...
I don't know if it the intention of this forum but that will be told by some administrator. Obviously you need an answer quIckly and if you haven't solved the problem yet; you may want to look at a false lean situation, leak in exhaust system upstream or near lambda sensors 1.1 and/or 2.1.. ECU will...

A block of text is normally needed to describe a situation, don't think there is too much nor too little info given, don't yap just for yapping Robski, in Spain they call that being "pe...
What am I saying, this is not piezo, this is ordinary coil so then it must be a driver problem, too much reading about piezo injectors I guess, anyone?
Hi All, Anybody seen this before, I have to decide (preferably without changing injectors locations), if this is a driver problem or an injector problem? DTC on arrival, injector 1 outside regulating limits. Sometimes ran on 3 cylinders even after restart and @idle. Started discarding probable cause...
OK, forget that last question. Already saw that I can select +-1V/div and then zoom in on the 500 mV (ambient pressure with this 1000 kPa sensor) area, with the 2204 best resolution here will be 1/256 (8 bits) of 2000 mV (+1 to -1 V DC) = 7.8 mV, correct? On screen slightly different though, signal ...
Hi Steve, Thank you for that challenge as every day I study here at Pico, and I too, like us all, are learning about such techniques and features. Whilst digging and delving into the pro and cons of Vertical Resolution I found this great short video on our PicoTV channel on YouTube https://www.youtu...
Let’s continue the story a bit. The client called me this week that he had fitted all the new stuff, electronic pickup/reluctor, new coil specified for this car using resistor wire, new resistor wire, new distributor cap and rotor, but that the misfiring remained the same so that those parts apparen...
