Hello. I have an Autronic SM2 that I'd like to install on an LS1 and it requires cam and crank triggers. Is there an easy way to install cam and crank trigger sensors on an LS1?

Thanks
Ben

What is an SM2?

Can you just take signal from the factory sensors or does the crank signal need to be converted to 4x or something?

The autronic needs 4x crank signal, which it looks like the FAST decoder box can produce. The #1 crank trigger needs to be 60 deg. BTDC. (60 degree trigger angle)

the cam signal- can be hall effect or magnetic. I'm not sure what the stock signal is. Anyone know what the stock signal is like?- when does it trigger? Is there only one signal per camshaft revolution?

Also- the cam signal has to be between 50 degrees BTDC compression stroke and 20 degrees ATDC combustion stroke

Thanks again Pro Stock John

1. The FAST decoder box converts the factory 24x signal to 4x.

2. The factory cam signal is hall effect.

3. You should email Kurt @ W2W, his email address is kuperf@aol.com. He can get you the crank box and help you install it.
