kotbehemot Posted June 23, 2014 Share Posted June 23, 2014 Strange thing is happening when i am accelerating:- 2nd gear / ~40 km/h- then full acceleration - boost gauge is showing steady 0.65 bar (not rising)- ... suddenly ~0.9 bar and fuel cut This "overboost" is not happening everytime. Do anybody have idea why it can happen?Where should i look for the reason of this situation?Westgate or actuator is jamming??Any suggestions will be appreciated. Car spec (EP82 with 4E-FTE):- standard CT9- standard fuel pressure- exhaust 2.5" with end muffler- standard TMIC + standard DV (as blow off now)- Apexi air filter mounted in front of the radiator- EBC => MAC valve + piggyback DET3 Piggyback is controlling boost level (0.65 bar) and spark advance (up to 5 additional deg in highest rev).It is not changing signal from ori MAP sensor.

5e colin Posted June 23, 2014 Share Posted June 23, 2014 maybe the ebc solenoid is acting up ?? Quote Link to post Share on other sites
mikey4410 Posted June 24, 2014 Share Posted June 24, 2014 I have always had manual boost controllers with no issue at allbought a brand new gizzmo for 200 quid and it kept overboosting, has put me off ever having another ebc.im sticking with manual boost controllers now, I tryed all the different settings on that ebc and it was fucking wack.waste of money.worst bit was I cant sell it as its useless.

kotbehemot Posted June 24, 2014 Author Share Posted June 24, 2014 Theoretically ebc solenoid is new ... but who knows. I still have few months of warranty. If i will have time, i will connect additional MAP sensor to vacum line that powers the actuator and check what is the pressure there while i have that overboost.If i wont have time, i will just make a claim and let "them" to check it (or most probably change to new one).thx I still have my MBC but for me it was pain in the ...I was not able to have the right setup for cold and warm weather, boost spike after gear drop was occurring, etc (planned boost level ~0.8 bar).Thats why i have "invested" and bought EBC solenoid. It wasn't so expensive upgrade (~60 Euro), because my piggyback has 2 power outputs (up to 5A).It would be a big waste if i wouldn't use those. I made simple map for it (work of solenoid depends from boost pressure and revs) and it is working ... almost perfectly ;) Quote Link to post Share on other sites
