Title: Audi A4 B5 1.8T Post by: MADMARX on October 10, 2012, 11:51:16 AM Hi all
Wonder if anyone can help me with my audi A4 B5 1.8T 2000 model. I have upgraded the standard turbo to a T3 turbo with internal wastgate and upgraded the standard injectors to Audi S3 injectors. Now the car runs fine when cruising but as soon as i slam it down on the throttle it feels like the car is holding back or going into limp mode. I have been looking at maybe flashing the ecu if that would help? and what file would be the best to use? Oh i have disconnected all the sensors on the airbox, will that create a problem? bring on the insults, im new to all of this lol. Thx Madmarx Title: Re: Audi A4 B5 1.8T Post by: byzan a4 on November 10, 2012, 02:54:09 PM So you are running with no N80 and MAF and no tune at all on a t3 turbo of somekind ?

It needs more caution while tuning the fueling and someone who knows should do it. Without injectors calibration (you run 4bar with s3 injectors), with maf unplugged etc it really make me think once more that 20VT are very tough cars :D Yes ecu remapping is needed and i dont think there is a ready file for your car to flash it right away. You know how to flash it? Those ecu may be stubborn with nefmoto tool. |
