  1. Fuel Trim table 4 missing

    Excellent tech support as always, thank you. I hadn't got as far as programming ECU as I wanted to be 100% happy with what I was setting up, hence the reason for seeking your advice... As you probably guessed, I'm not an experienced tuner, so apologies if my query was a daft one!
  2. Fuel Trim table 4 missing

    David, yes that's correct, I was seeking to monitor the fuel correction on my closed loop lambda setup (out of interest and to lean about it!). Thanks for the tip. Probably my inexperience, but I had assumed that the fuel trim tables were populated by the ECU as the CLL system made fuelling corrections. I'm still unsure why I couldn't add the fuel trim table for cylinder 4 though.
  3. Fuel Trim table 4 missing

    After reading a thread about using the Fuel Trim tables to evaluate the accuracy of fuelling (ie table should contain all zeros if perfect), I tried setting this up. I successfully added trim tables for cylinders 1 to 3, but couldn't add the 4th table, screenshot attached. I tried the same process on another 'random' pclr file and this worked as expected. Bit puzzled, please can you advise? Fuel trim 4.bmp 350. Fuel trims added.pclr
  4. Closed loop boost during FFS

    Thanks again Adam, I have tried your idea of a 2nd boost table and the results are great. Pic attached...
  5. Closed loop boost during FFS

    Thanks Adam, that is a great idea, I am confident that will work, I'll post my results when I have them... Many thanks for your speedy response...
  6. Closed loop boost during FFS

    I have closed loop boost control setup, which works perfectly, until I use Flat Foot Shifting. During a FFS gear change, the P and I terms of the control system become 'active' and attempt to correct the drop in boost. As I see it, I have two options: 1. Somehow disable the P and I terms during gear change, or 2. Maintain target boost during gear change. Please could I have some guidance?
  7. Throttle blip on Impreza STI 2007

    Thank you for the advice, much appreciated.
  8. Throttle blip on Impreza STI 2007

    Is it possible to configure a throttle blip on down shifts with standard H pattern manual gearbox? I previously had this feature on the standard Subaru ECU using EcuTek RaceRom which worked quite well.
  9. Closed loop boost control on Impreza STI

    Thanks to both Adamw and Brad for your replies. I mentioned my wish to experiment with closed loop boost control to my trusty tuner, Martyn Jeffery, who promptly returned my .pclr file with closed loop enabled and the various parameters set to a good starting point. Having progressively done a few logs, the results are far better than I could have hoped for. Nicely in control and no overshoot. Thanks Martyn, great job! I will continue monitoring under various conditions, but I am confident that it is running safely and in control.
  10. Closed loop boost control on Impreza STI

    Thanks for your speedy response, much appreciated.
  11. Hi, I have been researching closed loop boost control and came across a previous post that has deterred me, please could you comment on the following?... Andre Simon's post: I've mentioned this in a previous thread here, however I'll just caution you that the current closed loop boost control in the G4+ is problematic. Particularly if you're fussy, you'll find it impossible to get 100% accurate and repeatable boost. Link are aware of this and there is an update in the pipeline. Until then personally I'd use the passive closed loop setup discussed in the course.
