 +One of the biggest issues in getting started that was noted there was how to send the ECU a crank signal.\\ 
 +The solution presented on that page was as follows: 
 +<code> 
 + 
 +So in review, the GM Series II & Series III 3800 engines will run just fine on the Holley system, with LS coils and using the factory crank & cam sensors. 
 +You will need to set the Firing Order to 5,4,3,2,1,
 +Use the Custom Ignition Type: 
 +Crank - 1 Pulse/Fire - Digital Rising 
 +Ignition Reference Angle 75° and using the 3x reluctor on balancer. 
 +Cam - Single Pulse - Digital Falling 
 +Inductive Delay - 100

 +A later post on that page mentioned it would also be a good idea to synchronize timing in Holley as well.
