Motronic

[John Hess]

Let me interject something into this discussion.

I spent several hours, last week in the company of Steve Cole (The 
Turbo Shop) in Compton, CA.  Steve makes some products that he sells 
(Mastertune and Mastertune Plus) that allow one to read and modify the 
mapping and other settings on your EPROM.  He has other products under 
development that cannot be discussed at this time.

The point I would like to make is...if he gave the settings he uses, 
they might or might not work for your application (and might not work 
at all!).  He sells the tools for you to use to not only remap your 
PROM;  but, to LEARN.  If you were given too much free information, it 
would stagnate your progress.  There are some things you need to learn 
on your own.  The basic information is available;  but, don't 
denigrate someone who has been helpful simply because he won't 
broadcast the source of his/her livelihood to the world over an open 
internet forum!

Take what information they will disk out and use it wisely.

On the other hand, I DON'T TOLERATE THE RANTINGS of a supposed expert 
whose intent is to discourage and belittle!

I respectfully disagree.

Interesting.  The only people who I have found that want to "share it" 
are
those who the info cost them nothing. Nothing, as in no expense, no 
sweat,
no long hours pouring over code or ECM hardware. In other words, they 
got
an illegal copy of say, a GM calibration document and have no problem 
passing along someone else's effort.  The info is not valuable to 
them, as
they "paid" nothing for it.

In Jim and Todd's case, I fully understand their reluctance to put it 
all
that effort out front, and most would not understand it anyway!

I have seen "read-it-in-a-magazine ECM experts" on various automotive 
mailing lists, who must have never seen a line of code, telling others 
how
things work.  Their mis-information is sometimes amazing.  I responded 
to a
TPS question once, and got a "Clearly, you have no knowledge here"
response.  It was because of the "common knowledge" that these experts 
continue to purpetuate.  It takes a long time to stop urban 
legend....

Even book authors and magazine writers can put out mis-information.  A 
popular book says "Rotating the TPS counterclockwise increases the 
voltage
and results in a richer air/fuel ratio......"  This is in error, but
because it is published, I guess it is considered truth.... ;-)  Or a 
recent magazine article that said "The oxygen sensor .... is the 
primary
input to the fuel delivery system."  Another serious error.

Jim and Todd have taken the considerable time and effort it takes to 
really
find out how the BMW/Porsche boxes function, (and did not read 
magazines to
get there) and most here do not understand the time and serious effort 
involved, or their level of expertise at this.  (Just ask the person 
who
said they had 1% of code commented and gave up.  The only real 
difference
between Jim/Todd and this person may be that they did not give up!

I like Jim's offer of help to those who would help themselves.  It is 
admirable and shows true class in my opinion.... YMMV.
