Yeah, only takes one time of doing that and hearing a zap to never do it again lolI’ve owned IDS and AE, but not the ForScan laptop version. What is missing in AE and ForScan is the uncompensated injector balance test.
However without having IDS, you should be able to turn off individual injectors and still see how the engine reacts; the same or worse, which would tell you what injector is bad with either AE or Forscan laptop.
You also could do that manually by lifting the injector connector cir-clip or removing it entirely off each injectors connector and lift the connector off. Myself, I would probably do that without the engine running then the engine started to assess. I personally don’t like to interrupt the live circuit.
