evry mod - no constant boost at low rpm
evry mod - no constant boost at low rpm
Hi, just did the evry and installed a boost gauge. At lower RPM the gauge shows that boost is not Constant and i can also hear the turbo not spooling up in a line...hope you understand. Without evry everything is good. Also boost is lower when evry is in....is that normal is there a fault?
(08-23-2015, 10:34 AM)Repetitio you also do not have the stock turbo running in your car right? I will make a picture tomorrow and post it.
Yes, your correct but your turbo is vac controlled so it shouldn't mess with it??
I have no wastegate and there is no flutter etc
Anybody else with a stock c250 turbodiesel only with evry having not the problem?
i checked my solderings again...everything is fine, i think it has something to do with the boost control...The car builds preasurre to 1,5bar, then stops, goes down to like 1 bar, and goes up again. Until i reach like 3,5k rpm, then its constantly at 1,1 bar or something like that. is there a way to trick the ecu?

My brothers 250TD (completely stock) does the same "pressure change thing" at lower turbo pressure levels, so that seems to be normal.
At full throttle a jump to 1,1bar, then down to 0,7bar and then leveling at 0,9bar

thanks a lot volker for the info, now i know that there is nothing wrong with my car!
If I connect the vacuum line directly to the actuator the turbo builds up more than 2 bar. Thats too much. Could this be reduced by something like a boost controller? like this: http://www.ebay.de/itm/Boost-Controller-...5679b0e628
Or anybody got another idea how to control my wastegate the easyest way?
ok so it seems like some poeple have this problem...anybody got an idea how to solve this? i would like to get constant 1,5 bar or something like that.

Now: Q7 V8TDI 240kW, 320d 150kW, 335d 210kW
Yes you could set pressure with that valve by leaking vaccum from actuator but I dont think you get full bottom end performance. Your wastegate will still have to by slightly open and that affects spool up. Simply said no, you would need to fit some pressure operated wastegate turbo to get steady boost and good spool.
