VAG 1.8T 20V tunning file problem

[BRASTY]

487850I have a stage 3 BJX engine (bigger turbo,camshafts and injectors). i have problem with boost pressure, i can't go higher than 0.8 bars. the tuner told me that he has setted up boost pressure to 1.2 bar but still can't go higher than 0.8 bar. can somebody check my file to confirm that my map is ok???? i need 1.2 bar boost pressure

you have any logs from car? you get any dtc or limp?

[BRASTY]

how to get logs? i have wow clone (wyrth) and i borrowed kess for a few days to read my map

[ivanrojo]

vagcom or me7 logger, probably you have a problem on your turbo or your n75,

[maajkii]

N75, DV, boost leak, underpressure.... a lot of parts to check :)

i have cheked everything. i even swaped all sensor form a car that works fine ,i cheked wiring. i'm almost sure that the problem is in ecu, can somebody confirm that the setup of my map is 1.2 bar? with vcds i read 0% duty cycle at 0.8 bar

Hi, i mean file is good, i have same problem with car like you.... In my case is bad fabric blow off valve (spring have small pressure for valve, when you boosting, your boost leak back to filter...

I think problem is in KFLDRL, please test this file

it is not turbo bro, is turbo control in sw

[Pyromaniak]

to n75 come vacuum, no pressure. DON´T WOORY YOU LEARN IT :D

If you have tested n75 from ok car, maybe is vacuum leak on your car

are u sure u have the correct connector from n75 on the n75 not the connector from n249

your dtc from n75 is off :-)

than why all rpm so high ??
bad idle or what ?
tell us what injectors ,hfm , inside ?
i think deka 630 and s3 hfm
what turbo is inside ?
test how many boost u now have i have also enable n75 dtc

your problem is with your intake something ,check map sensor or n75 valve ,can you check spark plugs which color are ,if are the white color the problem is in fuel system no fuel as well

is not intake system . problem is software or wrong plug for n75 or n75 defect . n249 and n75 has the same plug that is why i say check this. i have many car with reversed plugs
