    knock threshold

    i see. changing load axis to MAP would give better protection given higher pressures can be achieved with relatively small throttle input. I'm not sure what number would be considered actual knock, and not noise. My last tuner said it would be a pretty obvious spike. I'll change that load axis, and rebuild the threshold table, thanks for the input Adam.

    knock threshold

    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. added boost.pclx spull.llgx
  3. Thanks for the reply. Which option do you think is more cost effective? I live in the US. I've seen the external e throttle available for around $350. What is the cost modification service? Do any dealers in the US perform this modification? Thanks again for the info Adam
  4. Planning on setting up drive by wire soon on my version 4 STi(link g4x4x). I've noticed some kind of modification is required to allow DBW to work properly. Anyone know what is involved, and the procedure to get this done? Is it a software, a firmware, or a hardware charge? I'm almost positive I read this ecu was capable of DBW when I bought it. Guess I misunderstood..
