LSPI (low-speed pre-ignition), full disclosure: who started it, and when? 1950? Nope... well, a little. 2009, to be honest. That’s when small turbo direct-injection engines took off, and the problem showed up with them. So what’s the calcium reaction behind that rogue LSPI spark? Truth is, nobody knows for sure. Calcium is the prime suspect, but the science is far from settled. Let’s get into it.
