If it's a Blueprint engine make sure the vacuum advance is disconnected and your max advance is around 34 degrees and you should be good to go!
Hi John,
Thanks for the review and the input. My engine is a Ford Performance Boss 302 that Forte built for me that included an Edelbrock ProFlo4 EFI so I am not sure if the the tuning recommendation you are providing is applicable or not. Once I got the fuel pressure set correctly at 58 psi, I then used the Edelbrock app to make sure everything was configured properly. At first I could not get the engine timing adjusted (could not see the mark) to the set up app's requirement of 16 degrees and the engine idled terribly (worse than before and would some times die). Being a newbie, I stopped and shut everything down so I could research what I was seeing as I figured I was doing something wrong. After searching the web, I discovered that the Boss 302 (also called 302HO) has the same firing order as the 351 and not the stock 302. I reran the configuration utility setting the correct firing order (351) and was able to easily set the timing as directed (12 degrees advance). I set the idle target to 700 rpm (some what arbitrary choice as I have no experience to set it any differently) and after finishing the setup, the engine idles very nicely (better than the first start idle) and starts right up on the first crank. Let me know if my idle target is too high or low or if you see something I have missed.
Best Regards, Andrew
