Starbuck Posted September 13, 2011 Share Posted September 13, 2011 When running off the spring (TIAL EWG) the car will boost fine with no issues. However when i turn on my Profec spec 2 and floor it, under low and high boost settings i get a stuttering. Under Low boost it starts about .7bar but will eventually (sort of) clear the stutter and get to the low setting of .8bar.Under High boost it hits .7bar but won't clear the stutter and get to its setting of 1bar.I'm running Emanage Blue and have only started getting this in the last couple of months.Not the clutch as ive just had one fitted.Any Ideas???

Starbuck Posted September 14, 2011 Author Share Posted September 14, 2011 Noted. CheersAny other suggestions? Quote Link to post Share on other sites
Socks Posted September 14, 2011 Share Posted September 14, 2011 sounds like fueling... remember. if your emanage is mapped to 0.7bar if u turn it up on controller to 1bar. it'll underfuel... and run lean. vice versa. if its mapped to 1.0bar and you run at 0.7bar it'll be over fueling...?

TrisK Posted September 14, 2011 Share Posted September 14, 2011 spark plug gap, standard is 1.1mmanything over the standard boost and youll need to reduce that to like 0.8 Quote Link to post Share on other sites
Starbuck Posted September 14, 2011 Author Share Posted September 14, 2011 The blue was mapped at 1 bar IIRC. But ive been running it since Japfest 1 with no issues on both settings of the boost controller 0.7 and 1 bar. The Plugs were changed earlier in the year as well again with no issues. Its only been happening in the last month?? Quote Link to post Share on other sites

Socks Posted September 14, 2011 Share Posted September 14, 2011 hhmm. yeh try ignition side of things...see if unplugging your lambda makes it worse... Quote Link to post Share on other sites
Starbuck Posted October 3, 2011 Author Share Posted October 3, 2011 Changed the dizzy and rigor. Still doing it after fitting..... So thinking about the boost solenoid as mentioned before I checked the vac lines and adjusted one dubious looking bend. Boosted it to work this morning and it hit .8 no probs..... Tried 1 bar and it reached it better than before but still with judder. Adjusting the bends a bit more, so ill know tonight if it was relocating the solenoid that caused it.....
