QLCC info (for starters)

[kavanagh@kodak.com (David Kavanagh staff)]

I'm posting the mods to the standard Mac-11C code from my car. I think
it works with Mac11B and Mac14 ECUs as well.

This is the readme file I keep with my other files to help me keep things
straight.  I've been running what is called 1.2 since September '97. It is
not clear to me that the increased duty cycle at WOT is necessary (or doing
any good), but I felt that a little rich is better. When I get off my but and
monitor the O2 sensor, I'll get a better feel for mixture. (Or I could use
that thermocouple meter I have to monitor exhaust temp like the big
boys do!)

PS. I have some other useful info that I started with from Scott M and Orin,
but they didn't sent it to the list, so I won't (unless they are OK with it).

Mac11-C modifications:

audi.* = original code
	code as dumped from prom.

========================================================================

audi10.* = version 1.0 modifications (11/96)
	1. modified boost fuel cutoff curve (raised limit to near 1.95 bar).
	2. modified desired boost curve (so wastegate will help us get there).
	3. modified wastegate modulation based on RPM.

diffs between original and version 1.0:

========================================================================

audi20.* = version 2.0 modifications (Under development)
	1. increased boost fuel cuttoff to actual 1.95 bar.
	2. increased O2 duty cycle for WOT
	2. increased desired boost curve so max is 1.90 bar from <3770 - >5180 RPM.

version 1.1 contains 1, 3
version 1.2 contains 1, 2, 3
