    thanks for sharing your findings! Those Knock sensor changes in some of the tunes are quite interesting! Def. very useful info when deciding what tunes to go with.

    Very interesting research! I enjoy this type of video a lot.

      @@mygolfmk7209 I've been reflecting about this since I saw the video, do you think that the knock values on the more aggressive tunes (Sneaky, EQT) were affected by the fact that they recommend colder plugs? Do you think that the results would've been the same with the recommended plugs or did you do the dyno/pulls with different plugs for these tunes? It still doesn't change the fact that the knock sensors treshold is modified but I am curious to see if this changes anything.

      @@RSXengineering I had 2 step colder plugs installed while comparing these tunes.

    Jeff, I really appreciate all your work on the mk7 platform. Your website is an invaluable resource for owners and enthusiasts. The data and analysis presented have been very helpful in planning my own build.
    I was disappointed to learn that 034 was not willing to submit their ECU software to your testing. Consequently, I will be switching to a Stratified tune. I had been running 034 due to the perception that they offered a relatively “safe” tune (but who knows without verification?).
    According to 034’s TH-cam channel, they don’t defeat any of the OEM safety measures, which after viewing your analysis likely means not raising the knock retard threshold like EQT or SneakyTune does. Like COBB, this results in a little less power compared to other tunes, but I figured was worth it for better reliability. However, I thought it was interesting that Stratified achieves more power without numbing the knock retard either.
    I wonder if this evidences a more skilled tuning capability by Stratified than say EQT or SneakyTuned who do numb the knock retard (assumedly, in exchange for more power). Perhaps that’s an easier way to achieve more power, but there are risks.

      Thanks for the feedback! Sorry for the delay in responding, I've not done well with following up on the content I post on TH-cam.
      I believe numbing the knock sensors is a simple approach to addressing the issues that arise when increasing power output, and gives consumers a false impression that they are making power safely. My guess is that choosing to raise the knock threshold is primarily done for marketing reasons.

    It's interesting - I would love to hear the tuners responses to the change in threshold. Without knowing much about KR, I could see that with the other variables changes, there would need to be some changes to the threshold to avoid "noise" caused by the other changes. As in, are they perhaps safely addressing false knock created by bumping up boost, timing, etc?

    • @mygolfmk7209
      @mygolfmk7209  9 หลายเดือนก่อน

      Increasing boost and timing are a couple methods for increasing the cylinder pressure, which is what leads to more power. I'll be putting up a post tomorrow (4/8/24) that shows the effect of adding some E85 to the Stratified Revised tune. That tune had a bunch more KR than the OTS tune, so if there is just more noise, and no more knock, the amount of KR will remain the same.

    Thank you so much for the information. As an aviation technician who has worked in the research and development side of things, I know how important it is to have data instead of guessing. May I ask you, which stock mounted intercooler you'd recommend. I went to your website and the amount of data is great, but I felt overwhelmed.

      For the weight, airflow and thermal management, these are your very best options:
      APR
      DO88
      Mishimoto
      Unitronic
      This is verifiable not just with Jeff’s website, but by reading through hundreds of threads in the Mk7 community where folks living in brutally hot climates were able to keep their power output and IATs consistent and in a safe range. 👍

    • @mygolfmk7209

      It depends a bit on your application. I've been using the AMS IC a good deal because it cools very well. I also like the APR IC. I think the difference between almost all of the stock location options is negligible for an IS20 or IS38 application.
