it's nice to have both. PE for really heavy TPS (when you stomp on it) and low vacuum regions of open loop for really heavy load (where you need more power and need to keep combustion temperature down, but you aren't necessarily trying to accelerate rapidly)This being my first experience with open loop, I began to wonder if there's any point in continuing to use PE with an OL tune. Why not just tell the AFR table what you want, where you want it?
the knock sensor isn't there to prevent you from cracking a piston by making horrible decisions with timing advance; it's to allow low quality fuel to be used while maximizing performance with higher quality fuels. it's not a very good tuning aid, and railing up timing until the knock point is a bad approach to maximize power, imo. just add timing until it stops making more power (or less vacuum, if we aren't at WOT) and call it a day. this is super easy with eehack's timing skew feature.I think you're close to converting me. I just have a bit of a hang-up on not wanting to risk cracking a piston with detonation.
