    Yes, the car was completely normal during this. Cortana comes with Windows 10. A quote from google... One of the standout new features found in Windows 10 is the addition of Cortana. For those unfamiliar, Cortana is a voice-activated personal assistant. Think of it as Siri, but for Windows. You can use it to get weather forecasts, set reminders, tell you jokes, send email, find files, search the Internet and so on. I haven't switched cortana back on to verify that the problem returns, guess I should for completeness...

    Has anyone experienced problems with data logging freezing/stuttering? Picture below showing what I mean (no activity either side of cursor). In my case, switching off cortana fixed the problem... (who wants cortana anyway?)
  3. Clint, how do you get EGT? Is this using the heater temperature if it goes above the regulation temperature of 780 C?
  4. Clint, you're a star, thanks for your help. The more I learn, the more I realise I don't know! With regards the overrun fuel cut, I use the filters on Mixture map to filter out any samples when this was active. I guess you don't approve of that method from what you say? Do you think I should keep 'IAT fuel trim' active during tuning (but all other corrections off)? As I see it, I need to compensate for inlet temps otherwise the tune will be wrong when the weather warms up? I always use V-Power or Momentum, so should I change my stoic value to 14.5, or keep it at 14.7 to cater for any fuel? Sorry for all the questions! Cheers Tim
  5. Clint, I'm confused... My fuel table uses MGP (to compensate for altitude effects) ? My Lambda target table uses MAP. I'm not sure what you are suggesting when you say: More getting the axis correct in revs and pressure, weather you use MAP or MGP or PSI makes no difference as both are only a math calculation of the raw ADC. My target table does not have many cells (it's not a complex map). It was my assumption that the ECU would interpolate the X axis as required anyway. Please could you expand on what you are suggesting? Cheers Tim
  6. I see, thanks, I will try that. Cheers Tim
  7. Thanks Clint, Are you saying I need to change my target lambda table from MAP to MGP and dimension it like the fuel table? Thanks in advance. Tim
  8. Hi, I have been trying to refine the fuelling on my Subaru Impreza STI 2.5. Please can I have some feedback on a couple of questions?... 1. Using Mixture Map to tune it, my fuel table looks quite spiky, despite using lots of samples. I've seen other posts where the table looks much smoother, should mine look smoother? 2. During cruise, Lambda is steady, but on a 'pull', I can't get it much better than shown, is this good enough or should it be better? Thanks in advance. Tune and log attached...

    Just a stab in the dark, try pressing F3?
  10. One thought, are you able to reload the old 'tune' to prove the problem can be reversed?
  11. An "electronic valve controller", sorry I never realised that. In that case, I guess you wouldn't want the Link ECU doing closed loop aswell. My mistake. Looking at your latest log, despite the oscillations they look pretty small in amplitude (it's zoomed in quite a lot). Bit stuck on this I'm afraid, apart from the fuelling on acceleration looking too rich. I could have helped with setting up Link boost control, but I don't think that's your problem now.
  12. I'm not sure what you mean by "EVC" ? I believe that you're basically running open loop, i.e. from the wastegate table. However, the Boost Mode is set to 'closed loop'. I don't think this is what's causing your "engine hesitation" problem, but it would be a good refinement to carry out at some point. From Impreza STI, 2.5 (2007), here's Target boost table: I think the first thing to tackle is the fuelling IMHO....
  13. I see a couple of things from the log that might be worth a look (pic attached) 1. It looks quite rich (0.68) at the start of boost, before stabilising later. 2. Boost Mode is set to 'closed loop' but the Target Boost Table only has a row for TP = 0%. It should include rows up to TP = 100%. Boost Status is shown as OFF all the time, due to the above I expect. Hope that helps?

    Knock and IAT

    Hi Adam, IAT in that region was around: 10 C winter 35 to 40 C summer

    Knock and IAT

    Hi... Please could someone advise on a Det query on Impreza STI? I spent a lot of time setting up knock control (frequency analysis, det cans, inducing controlled knock etc...) and got a really responsive setup and running completely knock free. This was in the summer months when it was 20 degrees C. Now it's colder (freezing), on occasion, the system detects a single knock event around maximum torque (5500 rpm, 240 kpa, see attached). Would you use the IAT Ign Trim table to resolve this? It's currently set to remove timing at high IAT only (see attached). Thanks
