What am I missing? Hex editor help
I was trying to figure things out and wanted to check my injector constant using a hex editor. Also wanted to verify the ecu was doing the math right. Used two different ecu's and they read the same so I assume they set my constant right.
AUJP, Super8dm-1.ecu, TunerPro, Hex editor that Traxion uses, XVI32 or something. Haven't really tried to use winbin yet.
Went to $41C as listed in the ecu and anht hac.
Number reads 01 in TunerPro hex editor and my other editor.
$41A reads 01 also when it's supposed to corelate to 14.7 or 465h or 460h. Ones the stock 24lb constant and the other is the stoich constant listed in the hac. Don't recall which is which. I understand my bin won't read the same since I changed my constant to 36. But the 01 in two places that I think should read 46xh has me lost.
I made a wrong turn some where. Help please.

Both of those terms are double byte values. Need to read two locations and add them up.
$41A will be $01 (as you found), $41B will be $BD. Take the $01 found in $41B and multiply it by 256, then add the value in $41B to it:
$01 * 256 + $BD = 256 + 189 = 445
Same for the Inj flow rate term.

Code:
L841A: FDB 0445 ; STOCH AF RATIO 14.7 ; (ARG = 6553.6/RATIO) ; L841C: FDB 0460 ; SEC/GRAM PROD OF INJ FLOW Rate
$01 * 256 + $BD = 256 + 189 = 445
Same for the Inj flow rate term.
