Software revisions

Version 1.1

• This software version uses the following RPM map choices:

RPM Map

Switch 7	Switch 8	Start Retard RPM	Full Retard RPM
open	open	2900	3800
open	closed	3200	4000
closed	open	3500	4200
closed	closed	3800	4400

Version 1.2 - 3/24/01

• Changed to a slightly less aggressive set of RPM maps::

RPM Map

Switch 7	Switch 8	Start Retard RPM	Full Retard RPM
open	open	1500	3400
open	closed	2000	3600
closed	open	2500	3800
closed	closed	3000	4000

Version 1.3 - 5/11/01

• Added the Jackson Racing/Moss/Sebring 15K resistor trick option.

Version 1.4 - 8/14/01

Changed the RPM display to precision tachometer. Modified the air temperature-to-retard mapping. Now, as air temperature increases, the ACU adds more retard independent of airflow and RPM. Previously, extra retard at high temperature was added only at higher RPM and airflow.

Version 1.5 - 12/20/01

• Adds a percentage of timing back in (via less timing retard) at higher RPMs, based on the amount of total retard the ACU is programmed for. This is of benefit to both forced induction and naturally aspirated cars.
