Title: quick 2.7t swap Post by: ktm733 on April 04, 2015, 09:20:36 AM Hey guy's i just bought the 2.7t engine and stuff needed for the swap into a b6 a4 1.8t. Question is i want to have wideband 02 sensor installed. I bought the 2.7t from a 2001 a6 2.7t not avant. Could i just use the 4z ecu from alroad that had wideband?

Ive heard of some aftermarket stuff but is there anything we can wire in to the ecu and be read in block data with vcds or even me7logger?

Quote or just weld another bung in place and add a second sensor. The most common solution. Also, there are several threads on NEF about wiring those into unused ECU inputs for logging.

Still have building wiring harness as the guy sent me a wiring from a b5 not b6 1.8t urghh
