[V8] ECU, IA chip, and Speed Limiter

[cobram at juno.com]

That kinda sucks!  Is it built into the ECU?  If Ned's chip doesn't
disable it, where did Audi hide it, and is it hardware or software?  I
stand corrected.  I've heard nothing but positives when it comes to Neds'
chips and mods.  I remember Keith mentioning an ECU swap or something
along those lines to get better performance from the 4.2 US version, but
couldn't find anything in the archives.

I live on a one-way street that's also a dead end. I'm not sure how I got
here, or how I'm going to get out.
