I'm starting to tune on 93 after upgrading turbo, intercooler, e-throttle, and external wastegate on my version 4 STi. it was previously tuned on e85, but we never got around to the 93 tune. Ive got the VE table close to my liking at spring pressure(12ish psi). now adding some more boost to the mix, ive noticed knock levels rising over threshold, no huge spikes, and not too far above threshold. im wondering if its normal for 93 octane to be a little "noisier" than e85, and if its recommended to set threshold on the 93 tune, and assume it will be plenty above the e85 "noise" levels? lmk your experience with knock theshold, and modeled multifuel strategy.
attached current work in progress 93 tune, and a log of a mild 4th gear pull.
