Boom! Another one has his car running better! I bet my lunch there are tons of N54's out there with miscoded injectors.

Has anyone gotten INPA to work with Win 7 64bit (Home Premium)?
I've tried on 2 different laptops following Vasil's excellent instructions, but still get the Battery "On" and Ignition "Off". Anyone know what's causing the Ignition to remain off or how to fix it? I am able to go through and see the injector codings, but when I try to change them, I get the explanation points next to the numbers |

There has to be something not right with the injector readings. Either that or your injector are way off and not even coded at all ever! INPA works fine with windows 64. Ncs will not

They were coded correctly before, but I got the exclamation points after I installed new injectors and tried to recode them. It's like the new coding didn't take.
My guess is it's a result of the Ignition light not turning black in INPA. There's some communication since I could read the injector coding before, but apparently not a good enough connection to code the new injectors. |

No error codes from INPA. Car starts and idles ok, haven't driven it though.
Any tips how to get the Ignition circle to go black when using win 7 64 bit? I got the cable from the same link as Vasil and windows found the driver. |

Yeah, the decimal separator is not where it is supposed to be.

Can you see whats written on the injector without taking them out or replacing them? I know that a while ago, 3 of my injectors were changed but I dont know if properly coded, so can I check? Can I check without changing or removing the injectors?
Thanks Also what are the simptoms of badly coded injectors? Poor idle and misfires with tunes? |

Correct. The stampings are on the top part of the injectors, clearly visible when the engine cover is removed.
