Fabio Posted January 18, 2023 Report Share Posted January 18, 2023 Hy everyone, I am in the process of installing a Link ecu on Impreza gc8 211cv, I wanted to start tuning on modelled straight away,does anyone have a VE table already dyno mapped that want s to share? Thank you Fabio Quote Link to comment Share on other sites More sharing options...
Confused Posted January 18, 2023 Report Share Posted January 18, 2023 The Monsoon base map will give you a good start - every single vehicle is different, even if fitted with the "same" parts, so you'll want to do a full proper tune anyway to make the most of it.

Adamw Posted January 18, 2023 Report Share Posted January 18, 2023 The VE table is the most simple part of the tune, you dont need anything anywhere near correct to get running. I have run engines with a single cell VE table as a demonstration in the past. You could use the V11 WRX VE table as a starting point, or just wack 80% in the whole table and it will run well enough to tune. Quote Link to comment Share on other sites More sharing options...
Fabio Posted January 19, 2023 Author Report Share Posted January 19, 2023 Thank s to everyone, I will do that for VE tuning, would you advise to use auto tune? Could you advise me on stock impreza v3 knock settings as well? Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 19, 2023 Report Share Posted January 19, 2023 If you have a G4X I would use the knock settings from our V11 base map. This uses normalised mode which adapts from engine to engine well and works very well in our test car (EJ207). Leave that until after you have tuned it though, otherwise it will just work against you. 5 minutes ago, Fabio said: would you advise to use auto tune? If you are doing steady state tuning on the dyno yes. If road tuning where you cant hold it nicely centered in each cell then you are probably better using the mixture map or quick tune function from logs.

Fabio Posted January 19, 2023 Author Report Share Posted January 19, 2023 What about IAT fuel trim table? Do you think I should set it off? I don t understand if the air density vs temperature formula is already in the equation, I mean if i set all IAT corrections to 0 does the equation still adjust for air charge temperature? Thank you Fabio Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 19, 2023 Report Share Posted January 19, 2023 In modelled mode IAT trim should be off and warm up enrichment zeroed out. Air density is calculated using the charge temp approximation and fuel charge cooling coefficient. Quote Link to comment Share on other sites More sharing options...
Fabio Posted September 19, 2023 Author Report Share Posted September 19, 2023 Hi everyone, I am in need of help for knock settings I would like to make my engine knock at low revs low loads to see if the knock is picked up by the link g4x I ve tried 2k rpm and maximum allowed timing but no knock occur How can I do this procedure safely? Or someone has settings already tested and working? Thank you Fabio Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 19, 2023 Report Share Posted September 19, 2023 I doubt you will be able to make it knock at 2000RPM with no boost. Maybe if you cover the intercooler to get very high IAT or use the lowest octane fuel. When testing our V11 sti I had over 45deg advance, 3000RPM, and maybe 120-140kpa MAP to make it knock. Try the knock settings from our V11 base map, it is a EJ207, but will likely work for an EJ20 ok. Quote Link to comment Share on other sites More sharing options...
Fabio Posted September 20, 2023 Author Report Share Posted September 20, 2023 Is this the correct expected result? Could I use this settings in ignition trims that is (for me) easier and more comprehensive? Thank you Fabio Quote Link to comment Share on other sites More sharing options...
