Jim C S/W Upgrade & Check Engine Light

[Josh <eurosprt@xxxxxxxxxxxx>]

>I have approximately 1000 miles on my 1996 328ic after getting my computer

The software upgrade doesn't inhibit or interfere with the dealers
diagnostic tools or procedures.

Your dealer will not be able to detect your software upgrade unless they 1.
drive your car past the disabled speed limiter of approx 140+mph or 2. if
the dealer drives your car to redline in all five gears and notices that
the rev limits are slightly different.  Being a former tech at a BMW dealer
I would have to say that the chances of this happening are highly unlikely
unless there is a mechanic at your dealer who is interested in loosing his
job.  The $100,000 DIS diagnostic tool cannot detect your modification.
Even if you told them that you have a software upgrade and they overwrite
it you can still have it re-written for free through the original Jim C
dealer (I believe that I sold it to you).

The only loss would be time (approx 48hrs down time) and cost of shipping.
