Thread: Learn Table

  1. #1

    Default Learn Table

    I've been working on cars with carburetor's for 40 plus years. In 2018 I made the switch to Holley EFI with a Dominator ECU. It was tuned on a dyno in July 2018 and ran great, but part throttle driving needed some tweaking. At first I contacted my tuner and he was going to look at it and make some changes remotely based on datalogs. I decided not to do this and started tweaking things myself based on what I read in this forum. As I refined the tune I noticed that the Learn Table would swing by about 20% plus or minus. It was noticeably lean or fat when at no boost part throttle. It now runs much better and the Learn Table is not making huge adjustments. Here's my Learn Table from this weekend Overlaid with a datalog. As you can see, the ECU is adjusting the tune by 0.1 to 5.9%. Wondering how this compares with other boosted applications on E85?
