CHAPTER 1 INTRODUCTION
Zipper’s Performance Products and Thunder Heart Performance Corporation
have joined forces as the “J1850 Alliance” to create products that are “J1850
compatible” for 2004-later Harleys. Thunder Heart’s cutting-edge technology
combine with Zipper’s expertise in performance to provide the rider with the
best products possible.
The latest product of this alliance is their Digital Ignition Module for 2004-later
carbureted Harleys
Users can program the module by either using the module-mounted
pushbuttons and digital display, or using the (sold separately) Smartlink
Software and Interface Cable. Users can also “offset” a pre-programmed
curve up to +/-5 degrees without having to link the software up to the module!
The ASM5075 has three additional outputs to control a “2-Stage” rev limiter,
a shift light, and an analog tachometer output for use with most aftermarket
tachometers. It’s a great way to configure the ZAP on your 2004-later
Harley!
