Part Throttle tuning for MAF (was MAF tables have a max of 255)

[Daniel Collins]

Yeah we had some initial problems with 808 reliability , this seem to have
been solve on the replacement ecu 16183082 not having seen or used a 730 I
couldn't comment but it just seem complex from the brief look I had at
cattuner.
By that I mean it seems easier to map the engine by setting the volumetric
efficiency correctly then the spark and a/f ratios for these load points. I
get confused with all the spark adder /power enrichment tables.
I haven't looked at MAF yet but I am hoping to try it soon on my Pontiac
using a 165 calibration then later progress to a sequential MAF like they
use on our later VT Commodores here in Australia . Need to learn how to
access the code to find the table locations first though.
I have a later version of scantool that reads the 16183082 at higher bauld
rate but it so far is of no use to me until I can find the tables in the
later ecu's.
