texci77 Posted February 7, 2007 Report Share Posted February 7, 2007 Hey guys, can any help me out with the tuning changes needed for the 42# green top injectors? I have changed the IFR vs the KPA, is there anything else that needs to been done to get these running right? Thanks. Quote Link to comment Share on other sites More sharing options...
Krambo Posted February 8, 2007 Report Share Posted February 8, 2007 To do it properly, you will need to scale your table due to FP variences during a WOT blast. I would suggest a WideBand to hone in on commanded vs. actual. What values did you enter in your IFR table? Did you reference the "RedHardSupra" IFR sheet that everyone tends to use? Here is his website ----> Good tuning links Go to the injector set-up and enter in your values of the green tops at the rated FP and then add your FP and the sheet will do the calcs. I am not sure if you will need to adjust anything with Idle or not using these injectors. Going off what others say, no, but I am not a pro tuner,...just a shadetree mechanic. I have a set of green tops sitting in the toolbox awaiting install as well. Quote Link to comment Share on other sites More sharing options...
texci77 Posted February 8, 2007 Author Report Share Posted February 8, 2007 Yeah, I used that excel spreadsheet of Supra's for my reference point. Thanks for the time on the other things too. Quote Link to comment Share on other sites More sharing options...
