1.7 bar Is it safe..??

[Taylorrr]

Mine peaks at 26psi, then after 4k falls and still holds it just over 20psi, is this normal?

Both related

ECU reads 1.55bar, and the airflow measured will be that of 1.7bar, so the calculations won't match.

I did wonder if this was the case with the high readings with the maf.

Extra boost will mean higher g/sec seen by maff.
You really want to be careful here since none of you have done any vagcom logs to see the worth of this. Speaking from experience you will be running lean during the boost spike, Rods and clutch are being risked. The spike is a short lived power gain with no real world gain to offer. where you need the extra omph is near the red line but since the map has not been adjusted the n75 will open the wastegate and kill off any potential gain.
An uprated actuator and custom remap is a different story though and is the way forward.
At least log 031 if your going to persist.

I wasnt really after trying to gain boost out of it just trying to bypass the n75 for a system that is more simple and wouldnt keep going wrong like n75's do.

Right update i hit limp mode again on the way home for exceeding max boost again.

So ive removed the MBC for the moment until i have more time to play with it.

But ive also descovered that my shareware version of vag-com will let me run logs as long as i run them one at a time. but wont let me run more than one at once.

So could someone please tell me the measuring block numbers for

Requested vs actual boost,

Also the one for the Maf reading,

Please

Edit: Dont worry ive decided to check the vag-com section which i should of done in the first place and found it...

115 and 002

you need full version off vag-com to log boost and block 115
what boost level did it happen?

Im not sure what pressure it was but it was in 5th again.

It was fine today with the n75 connected think i just need to turn it down a bit more but i havent got time at the moment to make little adjustments and test it because im working so im going to do it on my next day off..

I will have a go with the logs and see what happends i need to do a TB alinement really and last time i checked it was only $99 for the full version of vag-com so its not that bad really.

i got the full version for 99$ had some 5th gear limp mode to.much logging and small adjustments and it will be okey
