Well for my sins i bought the cheapest picoscope, and had a play with injectors but
My current need is to access the ecu and crankshaft sensor (easiest at ecu, if i knew pinouts). or an easy place for wiring access to back probe.
Is there a wiring diagram for a x290 or even how to get at the ecu.
My injectors are above the Fiat limmit for variance. I have scoped all 4 for voltage and current will eventualy post here when i know what im doing. I have access to an expert on diagnosing with a scope but he needs a waveform from the crankshaft sensor to tie in with existing traces to identify the one cylinder causing the others to compensate. I have also done a leak test and would like to complete scope tests before reacting.
While i'm asking questions if i remove an injector what parts need replacing with new? copper washer, high pressure pipes or connectors, leak off o rings.
how to clean up injector seat. Is there just one bolt clamping each injector.
