cpx4656 Posted December 27, 2018 Share Posted December 27, 2018 So from the sounds of this, cobb used 05-06 lgt to develop the kit for all 4 gen (05-09) but 07 - 09 are different in some of the connections ? Link to comment Share on other sites More sharing options...
Winrahr Posted February 2, 2019 Share Posted February 2, 2019 So is anyone else on Cobb FF yet? Just got tuned by JrTuned and apparently I am the first FF Legacy he's tuned. Link to comment Share on other sites More sharing options...
Code Posted February 2, 2019 Share Posted February 2, 2019 So is anyone else on Cobb FF yet? Just got tuned by JrTuned and apparently I am the first FF Legacy he's tuned. Were you tuned at Moore this past weekend? I couldn’t make it due to work. I have a kit that is ready to go but I not be tuned until April due to scheduling. What’s your setup and what did you put down on 93/e85? "Striving to better, oft we mar what's well." - Bill Shakespeare - car modder Link to comment Share on other sites More sharing options...
Winrahr Posted February 2, 2019 Share Posted February 2, 2019 Yep Moore/SixStars. Got tuned just yesterday actually. BNR 18G EWG. Stock headers. Put down 280/300 on 93 and 340/350 on E. Pump wasn't getting enough power to push 50psi base and car goes lean. Link to comment Share on other sites More sharing options...

How mush quicker does it spool on e? "Striving to better, oft we mar what's well." - Bill Shakespeare - car modder Link to comment Share on other sites More sharing options...
Winrahr Posted February 2, 2019 Share Posted February 2, 2019 AEM320 but needs upgraded wiring, car's running lean. It spools about the same on both, tuner doesn't want to push it too hard on lower rpms. My car's probably just weird lol, don't think it's that far from other VF40/18Gs though...

Code Posted February 2, 2019 Share Posted February 2, 2019 Ahhh I missed that it’s a 40/18 hybrid. I have the same pump and an iwire fuel pump wiring kit to install.

TheMonaLisa Posted June 25, 2019 Share Posted June 25, 2019 Who is running the 08-19 STi Cobb flexfuel kit on an 07-09 Spec.B? Link to comment Share on other sites More sharing options...
Code Posted June 25, 2019 Share Posted June 25, 2019 I’m running the 5-pin LGT (what Cobb incorrectly calls 2010+ LGT) on my 2009 LGT, which is identical to the Spec B under the hood.
