Boost drops from 1.1 to 0.6 at WOT in 6th gear
#16
I've tried to lower wastegate actuators rate (stock actuators)as MARKSKY said..but Nothing ..NO luck.
I' ve tried -1 mm on the actuators nuts..NO Luck , so -2 mm more (- 3 mm total) still NO luck..NOW my actuators are regulated as stock 30mm see this link http://forums.rennlist.com/rennforum...stments-2.html..BUT Boost is a little lower only in mid range and in lower gears (from 1.0/1.1 drops TO 0.9/1.0)BUT in 5th and 6th gear boost is still 1.1 and the problem is always the same: in 6th gear at 6400 rpms boost drops from 1.1 to 0.6 and remain at MAX 0.6 (limp mode) until i stop the car and turn off the key

I' ve got an X50 with Cargraphic/Rs tuning exhaust and flash to 1.1 bar.
Car runs great in all conditions but i've a strange problem: When i push at WOT in 6th gear and when the car hits 6400 rpms and 190 Mph boost drops from 1.1 bar to 0.6/0.7...This is limp mode because when this happen the car only boost 0.6/0.7 in all gears until i stop the engineand turn the key off.
My tuner has replace N75 valve and set wastegate actuators properly but the problem is NOT resolve ?!?
The strange thing is that the car goes in LIMP mode always when it's at WOT at 6400 rpms /190 mph in 6th gear ..
NO CEL and NO codes...?!?

The ecu use speed vrs rpm to calculate what gear you are in (thats how 1st is limited) If it is only in 6th it just maybe as simple as the tuner left some stock limits in place. One sure way to do that is to data log and run it on a dyno. If not you can just keep guessing away you may or may not fix/find it. GL

Just a question: How do you have understand that was time to replace your MAF to resolve the problem ? ..At How many miles did you replace it ?..and did you use oiled air filter when your prevous MAF has failed ?
Onestly my MAF seems work well ..my car has 40K miles and i've never used oiled air filter ..BUT for only $ 250 i think that to try to replace it is a good job in any case..
I will let YOU know if the new MAF solve the problem of boost as in your case
Sorry for my english

as the flash file is from Rs Tuning /Cargraphic that is a reputable company, before to go to another tuner i'll try with this new MAF hoping to solve this annoying problem

Thanks John ...i also thought this BUT my tuner has already checked the ECU map two times and he says that it is allright so he hypothesizes the problem is some failing sensor like MAF or O2 sensors But NOT having error codes he says that we must do attempts ..

Uno puo portare un cavallo al'aqua, pero uno non puo far bere il cavallo se non vuole.
Sara perche ti hanno detto di comprare un cavo Durametric e di registrare cosa succede con il motore quando ti casca la pressione in sesta.
Io lo facio ed e molto interessante vedere i dati. Tante volte uno puo scovare quel che non funziona. Ciao.
