VS V6 Enhanced 60lbs injectors won’t pull enough fuel

Post by jmsmotorsport »

Trying to tune a Vs V6 using the enhanced pack and a ostritch but down low can’t get the injectors to pulse low enough to pull fuel. Above 2000rpm it’s fine and adjustments alter fueling, I even lowered the injector size to near 0gs and nothing changes. Am I missing something a idle fueling control table? Seems very odd as I believe plenty of people use a 60lb injector on a hot NA v6?

Not sure about enhanced tunes, but I know in 12P there is a min pulse width scalar which I had once a problem with. I have FoMoCo 6 hole 40lb injectors and the default was 6.XX ms and it just drowned the engine no matter now low I set things, found that min pulse setting and changed it to 2ms and it fixed the issue.
