What is more interesting (to me anyway) is the programmable ignition control. I'm now running 5 BTDC at idle and currently 32 BTDC at WOT on 99 RON octane. Impossible with original SC ignition. This essentially means you can fine tune the otherwise very conservative SC ignition curve to match your specific engine and present day fuel quality. That may account for the 10-15HP gain. |
Thanks for the reply.
I read the info on Classic Retrofit's website, but I'm not clear on how it controls the advance curve. I thought that happened in the distributor? Perhaps that's different in a '78 than it is in my '73?
