with the old...
Here is a picture of the 60-2 trigger wheel that came
with my Esslinger power pulley modified for use with the Electromotive
ignition. This wheel is intended for use with a magnetic sensor to
create a crank angle or crank position signal.
However, I have since changed plans a bit regarding
computers. Originally, I was going to use an Electromotive TEC-3,
but for reasons I won't go into here, I wouldn't recommend Electromotive
products to anyone.
Then I decided to go with a Haltech E-11 and an MSD
DIS-4 HO Ignition... A GREAT computer system, but I've decided the
MSD system is not reliable enough for my tastes (road racing vs. drag
racing), and I wanted to go with a single vendor solution.
I am currently awaiting delivery of an Autronic SM2, Model B Exhaust Gas
Analyzer w/ NTK UEGO sensor, R500 Ignition and 2 Hall Effect Devices.
It's the last component that necessitated getting a new
crank trigger wheel. While I COULD have chosen to use a magnetic
sensor and a reluctor adapter, I decided that changing the wheel made more
sense. It eliminates an electrical component from the system, Hall
Effect sensors are digital, and properly installed, a Hall Effect sensor
delivers a better signal.
