Anyone have a used 3b chipped ecu, or 20vt eproms for a reasonable price?

[Ned Ritchie]

Patrick & all,

Alex's comment "The 3B's ignition system is simply not up to the task."
needs minor clarification:

While it is true that the 3B ignition is not up to the task of the higher
pressures that the 3.0 Bar transducer allows all hope is not lost.
 
IA developed a modified ignition that prevents those bent connecting rods
that were experienced by all tuners, and even Audi which led to the
development of Audi's use of individual coils.  This ignition modification
was not provided on the IA 2.5 Bar packages, but only on a few of our later
rare 3.0 Bar packages.

Yes we bent a few connecting rods using the 3.0 Bar package before this
modification allowed for the higher boost.

I ran this modified ignition with pressures at 97 inches of Mercury on my
personal 3B powered 5000 from 1986 while pulling a trailer up mountain
passes!

Yes, it is proprietary so don't ask. 

Ned

Ben, I do not know enough about these things to answer those questions so I
forwarded this string to Alex at IA to see if he could provide any input. He
wrote up the following and asked me to post this to the list as he isn't
subscribed. 

>From Alex at IA:
The best way to describe the VMAP is as a Bosch Emulator.  It converts the
value that its transducer is seeing into what the Bosch unit would normally
output.  It does not "truncate" anything.  It is exceptionally well built
and only after testing have we added it to our product line.

You can get more information about the VMAP here:
http://www.moreboost.com/

The VMAP, like all electronic devices, is susceptible to ESD (Electro Static
Discharge).  The effects of ESD might not be obvious immediately.  In many
cases ESD simply shortens the life expectancy of a given product.  I would
caution anyone installing it (or any other component) to do so with the
proper protective environment.

On the subject of 3 bar transducers. . . .

Several years ago Ned and I tested the 3.0 bar units with the 3B (in my 4k
race car).  After six months of trying to overcome the issues of extra boost
we determined that the extra power was not worth the risk, problems and
extra wear and tear.  The 3B's ignition system is simply not up to the task.
In the end, we went back to the 2.5 bar transducer and arrived at what now
is (basically) the IA Stage III+.

It proved to be a smart choice.  The car was run in 3 enduros (2 @ 6 hours
and one 8 hour), SCCA sprint races, numerous QCUSA track days (with multiple
drivers, there were days it was only shut off for fuel and lunch) and still
continues to turn laps for the current owner.  All it does is run on the
track and continues to do so after (literally) hundreds of hours.

Lastly. . . .

To avoid any conflict with the list rules, I don't post here (or on other
list or forums), to quote:

Please note that for sale ads of any kind(parts, cars, etc) and ebay auction
announcements are NOT permitted under any circumstances. Please make sure
you understand the Audifans posting guidelines before you post a message to
the list.

Frankly, after reading a few posts, I am a little confused.  Please clarify
the lists position on Vender (or Vender's Agent) posts.

Thanks,
Alex
