impellerhead Posted February 3, 2009 Report Share Posted February 3, 2009 How exactly should the settings for staged injection be if I have 8 injectors of the same size and I have tuned the engine with 4 injectors and don't want to change the values in the fuel map when using all 8 of the injectors. As we understood Sec/pri ratio should be 1 as all injectors are the same size and then in the staged injection table we set 50%. But this didn't work. In the end after trying all kind of different settings we had to change the fuel map to get the fuel right because it always wanted to go richer when the secondary stage was activated. Would be nice to get some help. Another question: I am now going to run 12 1680cc low impedance injectors (methanol fuel), 4 on the primary and 8 on the secondary stage. How should I wire them? And I would also very much like to know when the firmware update for onboard logging is coming for the LinkPlus G3? Quote Link to comment Share on other sites More sharing options...
impellerhead Posted March 4, 2009 Author Report Share Posted March 4, 2009 Is it possible maybe to get an answer or two on the questions above? / Fredrik Quote Link to comment Share on other sites More sharing options...
Guest Dave Posted March 25, 2009 Report Share Posted March 25, 2009 On board logging is available for the G3 if the firmware is updated to G4 this is a dealer only option though or it will need to be returned to link them selves as for the staged injection it should of run the same mixtures but this depends on injector placement and deadtimes as well as fuel pressure also suddenly switching the secondary injectors form 0 to 50% is not recommended they should be bought on more smoothly As for the new 12 injectors what engine is this on and where will they be placed in the runners Regards David Heerdegen [email protected] Quote Link to comment Share on other sites More sharing options...
impellerhead Posted March 27, 2009 Author Report Share Posted March 27, 2009 Great! I have talked to my dealer and will send the box for upgrading. I will check the settings for the injectors and get back to you. The engine is a 4 cylinder volvo 16v, the injectors will be placed on the upper side of the runners, a row with 4 injectors closest to the head and a second row with 8 injectors behind the first row.
