hi i got an 1999 audi a4 and i belive there is no MAP sensor and my ecu go in to limp moode where it get ower 10 psi boost and i would do a Diode to control the voltage to send ecu low voltage so it wount go in lipm mode but i cant.
My question is is there any other way to fix that problem so i can have about 18 pounds of boost and my ecu wount go in to limp mode would like to have it done cheap way thanks contact me at vodolaz19@hotmail.com if you have any info that will help me thanks

If your ndbw car is going into limp it is doing it because there is another issue.

Did you check for engine codes?

 

will this work on the 2.0 B7's as well or have you heard of anything similar without buying a chip and VAG COM?

 

What is the FPR?

 

i did check for check engine codes and i dont have any and no light is there any other way i can do something to have it run good thanks

 

Not a fan of buying no-name stuff from overseas on ebay but has anyone who've done this mod looked into something like this? For their EBC & gauge?

hi iv just joined the forum and have been looking this thred. Wot i know about audis you could wright on the back of a stamp lol..iv seen you talking about the boost settings. and they seem very high. my nissan skyline runs 320bhp and the turbo boost is 0.7 standerd and with boost controler i run it at 1.2bar..are you saying its safe to run a standerd audi turbo at over 1.bar psi.. as i think youll be asking for it to give up on you. but like iv said i know nothing about audis..ps iv posted a few things i need help with but not one reply....am i posting in the right place..im new to the forum and not very good on the old computer.... thanks

 

Nearly all of the chips out there for the A4 1.8t run 1.1-1.45 bar, my custom tuned K03 setup ran 1.8 bar(26psi).

 

If you diode the map and turn up the boost how are you adjusting and monitering A/F ratio?? This mode sounds cool but, unsure how safe it is?
seeing that the computer is getting false signals.

 

The ECU does not use the map sensor readings for tuning, it is just there as a safety in case the turbo over boosts.

When you turn up the boost the ECU will see a higher reading at the MAF sensor because of the increased amount of air flow.
