I picked up 4 new Bosch injectors (ECS super sale price). Most injectors I have worked with before had two 3-digit fuel calibration values stamped on them; you use a suitable coding tool (like ISTA or equivalent) to tell the DME/ECU what those values are so it can meter fuel correctly based on each injector's tested output.

Three questions:
1. Do these N14 Bosch injectors need to be calibrated for the DME/ECU? Or are they "plug and probably ok"?
2. If they do, I don't see an obvious pair of values on these injectors - any hints?
3. Can my Schwaben Mini scan tool do this task, or do I need to bring in my ISTA guy?

 

The answer, according to ECS and another source, is "no". Plug them in (use the correct seal compressor tool) and the DME will "adapt" to the injectors.
