im having some work down & the mechanic said he can use the VAGCOM to scan my whip. ive been having some boost issues with my KO4, as im only boosting to 15psi. I tried swapping in a N75F & it worked great- 20psi- for a week but then went into a "type" of limp mode even though i have a AEB. I put the stock N75C back in & im back to 15psi. I know the cold could be a variable too. Ive checked plugs,MAF, O2 sensor, DV, hoses, pressurized system etc....i can go on :)
anyways ive read about different blocks to check for regrading boost etc.
block 115 - requested boost vs. actual
block 032 - see how much the ECU is trying to adjust furl trims
block 003 - what type of reading the MAF is getting
block 011- coolant temp reading - going to check this since im there
block 015-016 - ignition coils
block 002 - MAF readings - i checked this & it works fine...
bock - - O2 sensor - i checked this and works fine.
ive read about a "throttle body adaption" to make sure its opening the correct %. how do you do this? I assume i can just have the mechanics put all this data on a flash drive or something. he said hell scan whatever & i can do anything i want with the info.
Are there any other blocks i should check for? i got some more reading up to do to double check everything. i want to have everything scanned that i would need to have. THANKS :)
