  1. I'd be interested to hear if anyone else has laggy software as I posted a comment a while ago about my issues... my laptop is pretty high spec and came with cortana. When switching this feature off, PCLink performance issues went away! I have not exhaustively proven this theory, but my laptop has been fine since... Ref:
  2. Dave, I initially thought that, but it is logged. See below... It's a bit strange though, if you type Batt in the parameter list, it doesn't appear as you'd expect! However, if you click on Batt Voltage, it's there! I can't explain that.......
  3. I would use a volt meter to measure the battery voltage (at the battery terminals) first. This should be around 12 V with the engine off and no electrical loads. Then start the engine and check that it goes up to around 14.3 V (as part of your log shows). This will narrow down where the problem is very quickly. Hope that helps...

    Logging status

    Hi, I've been working on a custom display and found that the ECU Logging status doesn't behave as I expected. When the memory is full, the logging starts overwriting the oldest data, but the logging status does not change state (from 1 to 3) to reflect this. Please can anyone enlighten me?
  5. I've also had a look, and have some comments in addition to Adam's... Would it benefit from tuning the wastegate table in open loop so that the control system has less corrections to do?

    Can lambda help

    That sounds right, I looked up this from the help file: For info, here's what my CAN settings show for CAN Lambda: Not sure if that help?

    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?)
  9. Clint, how do you get EGT? Is this using the heater temperature if it goes above the regulation temperature of 780 C?
  10. 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
  11. 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
  12. I see, thanks, I will try that. Cheers Tim
  13. 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
  14. 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...
