My son has a BMW e34 with turbo and ms2 system. It start easy with original injectors but when changing to Siemens deka 680 cc injectors it wont start at all. I have changed the flow in the setup according to the calculator. Shouldent the car at least start now? Rough idle mayby but it does not even ignite at all. If its not getting fuel at all. The original brain does not work on these injectors either. Tried the test program and cannot hear the injectors open . Neewbee needs some ideas

Have you tried firing them in injector test mode?

Yes, but nothing happend. We are going to remove and test them outside the car to see if they are destroyed.

With a multimeter measure the resistance of the injectors and report back.
