Snowman,
If you do decide to get a J&S, my friend (his website) http://www.american-pi.com/corvair/corvhome.html
http://www.american-pi.com/safeguard/safeguard2.html
would be more than happy to tell you how it all works & how to hook it up & which one to purchase.

You can purchase it through my friend or direct from J&S website.

J&S features.
A new, faster microprocessor is used .



Nitrous retard is built in and fully adjustable. Also can be used with turbo engines to heat up the exhaust for harder launches and quicker turbo spool-up.



Cranking Retard is built in and fully adjustable. This is especially helpful for turbos, high compression engines or non-turbo engines which run large amounts of static ignition timing. It also makes for easier starting in colder climates and/or higher elevations.



Preemptive Boost retard. Fully adjustable start settings and rate with test points.



Electronic vacuum advance. Fully adjustable start settings and rate with test points.



Selectable Rising or Falling Edge Input Trigger.



Selectable Rising or Falling Edge Output Driver.



Magnetic Pick-Up Trigger circuit is now built-in and fully configurable.



Two SoftTouchsm Digital REV Limits are now built-in and fully adjustable.



New knock sensor is smaller and has a lower profile. You can mount it on any cylinder bolt hole location which uses a 1/4-20 or 3/8-16 thread. It is small enough to be mounted right beside and under the carb.
