Dig's '749 $58 WB Patch


Note: Use at your own risk. I am not responsible if you
melt your engine. Go slow when tuning. . .


This patch allows the ECM to read the DIY-WB Vout via 
pin F14 and report the AFR value out the ALDL link.

The DIY-WB AFR is reported in the 'Commanded AFR' byte.


Files Included:

	DIG_WB00.txt:	This file
	DIG_WB00.asm:	Source code for patch
	DIG_WB00.lst:	Listing from assembler
	DIG_WB00.s19:	Binary patch file

	s19_pat.exe:	Patch utility to patch bin



How to apply patch:

Copy your current bin to another file to be modified.

Enter the command:

	s19_pat DIG_WB00.S19 0xC000 file2patch.bin

Note the last argument is the name of the file that you want
to be patched. This utility patches THAT file.


Calc the checksum, burn a EPROM and test drive!

; A note from that site: "Dig was explicit about the use of this 
; code. It is NOT to be used for any purpose of monetary gain 
; whatsoever. This code does NOT make the stock ecm use the Vout 
; of the controller to actually CORRECT the A/F ratio. It merely 
; displays the readings in appropriate reference point in the
; ALDL serial data. VERY important for tuning."
