Hi Installed EZ-EFI 2.0 with Dual Sync. 1971 Corvette 454 LS5 with TH400 Completed all the settings leaving timing at 20 degrees and adjusted IAC and so on. Vacuum and MAP numbers seems OK - Vacuum measured on Manifold Starts and idles and is drivable - BUT "LEARNING" never comes on ? Called Comp / FAST - holiday? Any ideas? Timing?
