I've been having a rough time getting my fuel nice and dialed using holley efi, mostly due to my lack of experience, so I let my nerdy side takeover (video to follow)

If you're in my situation then simply start logging, anywhere and everywhere.

I exported my logs to a .csv file and created a macro to determine where AFR under boost was 11.4-11.6. I then took my existing fuel map and inserted my good points from excel and used the "fill row value" feature to interpolate between them. I then smoothed the table a few times. I checked my work after smoothing reviewing the points I had previously used and randomly checking if my map was close to the known good points, it was.

It was a long shot at best but the result is shocking. With approx 20 good points my car is within a tenth of a point afr up to 6psi at the moment, which blows my mind because before it was very poor before. Long and short using a few GOOD points can do a ton for you!

Hope this helps someone!

 

What tuning system?

 

The only manual tuning I've had to do with a Holley system is in the idle and decel areas,the learning works everywhere else.

 

This is with a dominator. The learn does work well for fine tuning but I'm not big on letting it own my entire table
