My engine turns over at what seems like a slow rpm, always has. Always being at least since I put the IMI starter on many years ago now. I never knew exactly what speed til I put my current EFI system together. With the data logging I know now that about 182 rpms is what it sees before firing. I put this in this section since I figured folks here have probably logged cranking to sort out cranking fuel, cranking advance, etc on your EFI systems. If you know, post your cranking speed and what starter/ how much gear reduction it has. This is just a curiosity thing, I'm not trying to solve any issues.
Mine is an IMI with an advertised 4.44:1 gear reduction. Cranking speed 182 rpms.
