7.4 Installing the Six Shooter Acculink
Acculink Installations for Barry Grant Six Shooter®
Follow all the
normal instructions for the Acculink throttle position sensor
.
Install Acculink on the center carburetor only.
Remove the connecting rod from the front to rear carburetor and install spacers using longer bolts provided.
Re-use the original locking nuts.
Check linkage clearance at all throttle positions.
Install pins in ratio arm using Loctite®
Adjust the Acculink TPS so there is no play in the adjustable link rod. The TPS must have some preload.
Check the full stroke so to ensure the TPS does not mechanically hit the end of travel. This can damage the
sensor and make the COMPUSHIFT fail. The ratio arm has a long end and a short end. This will allow you to
adjust a stroke that will not damage the sensor. The long end UP makes the stroke shorter and the short end
UP makes the stroke longer. This moves the pivot point closer and farther from throttle shaft center.
7.5 Installing the AccuLink Refit Kit
7.5.1 Introduction
HGM Automotive Electronics thanks you for upgrading your cable throttle position sensor to the AccuLink TPS
system. We believe that great results can be achieved with a very careful installation of the cable operated throttle
position sensor. We have hundreds of people (including us!) who use it. However, the cable-operated system can be
difficult to get perfect. Some custom fabrication is usually required, and not everybody gets consistently great
results.
We studied this problem at length and came up with a solution that fits the most popular carburetors: Holley,
Edelbrock AFB, and Rochester QuadraJet. The AccuLink TPS offers the same or better performance with less hassle.
It is compact, and has a very direct linkage. Installation and calibration requires a few simple steps and no custom
fabrication.
Because the cable system and the AccuLink TPS use the same basic sensor and compatible wiring harnesses, we
can offer it as an upgrade. This manual describes the upgrade process.
7.5.2 Installation Planning
This manual assumes that you have an installed and working COMPUSHIFT system. Your system should be using
the cable operated throttle position sensor on a Holley, Edelbrock AFB, or Rochester QuadraJet carburetor.
AccuLink TPS is not suitable for other systems at this time.
This book describes the process of removing the existing throttle position sensor and replacing it with the AccuLink
TPS system.
The old system will be completely removed. Components from the old system will be removed and set aside for use
in the new system. The old system will not be reusable when the AccuLink TPS installation is complete.
7.5.3 Required Tools and Supplies
For installation, you will need, at a minimum, the following tools:
#2 Phillips screwdriver
