So command 4-3 is the default (high boost) then right? Command 4-2 is lower boost.

Might be overboost.Did not have that issue on 25 tho with the same mods,fuel etc.
Will be doing both solenoids replacement to try to improve my boost targetting and consistency...
GetBmwParts have them is stock for $111 a piece.

Why would you replace the solenoids unless the vacuum line test shows you are not getting full vacuum at 100% PWM?

If you just want to spend money it's OK but I highly doubt you have defective solenoids. That is *very* rare.

What is the minimum vacuum levels would justify replacment ???
What about a sticky valve that works one time and one time does not. I do build 18psi eventually on 4 gear,but way under target 2-3psi in 3 gear from 3k rpm up.

Refer to the "how to test your vacuum solenoids" thread for any additional info or questions on that procedure.

Hitting higher boost levels on small factory turbos takes a lot of heat/EGT in the system. It's normal not to hit higher targets until you've been under boost for a a few seconds.

BCEagle,

are you running the BMS backend flash? if not try that before you go to the upgraded fuel pump as it helped my car with fueling issues.

Also, I am seeing more boost in 3rd gear than in first and second as well.

I think it's totally normal to see more boost in third gear due to more load, I've actually seen on other platforms over boost issues in fourth gear and up.

Same thing here. Car went from lazy to crazy. Boosting again to 17-18 PSI quickly. What a difference from 27.2 . No more overboosting and jb4 switching to map 4. Anybody still on iso26...or 27.2 needs to update asap.
Looks like finally a successful iso update. Great job Terry.

I admit I refrained from following all the latest ISO version discussions as I am still happy with ISO 25 -- which helped to cure the low throttle oscillation issues I saw before.

However I am seeing comments from Terry on new FW releases on page 1 like "Corrected a bug ..." for which I would appreciate if it could be mentioned as well at which level the bug was introduced, just to help especially the infrequent followers here to better determine if trying a new ISO level might be worth it or not.

You can always load the latest and greatest and if you do not like it....... reload your older file.
Just remember to do a screen shot of your previous settings, if your the type to play around with them.
Only takes a few minutes to change hex files.

You are right cause it seems all updates since 25 had problems with bugs and stuff. I almost thought it was my car but apparently its not the case. How else do you explain the fact that the car runs strong and smooth on 27.3 . On 26.6 and 27.2 the car was laggy and weak. I had either underboost or overboost at times causing jb to switch to map 4 and stuff.The 27.3 looks like a champ so far tho.

You probably just had a setting wrong, etc. As I've said 10x times. There have been no performance changes since ISO19. This is all low throttle, rattle, transition/shift, type stuff.

I too was having issue's with 26.5 and 27.2 check engine and switching to map 4 with a 335is w/DCT.
Not the case with 27.3, it's smooth off throttle and through the gears whether in drive or sport mode, pulls 16-17lbs boost with no codes, no issue's, no check engine lights, loving it.
Terry thank you for working so much to make your product the best for everyone...well me anyway, just awesome.

I don't know anymore. But the car runs fine now on 27.3 same settings as before and problems with under or overboost have stopped.
