bmw325i 0 Report post Posted September 19, 2009 Just had an idea... Has anyone tried or know what the outcome would be of putting a m3 or mayb even a 330 airflow sensor in the 328? I know from old days in the silvias, if you put a rb20det airflow sensor in a sr20 you get a power and response increase through tricking the motor into sucking more air/more fuel etc, so thought id see if anyones done it to a bm. Let me know Jase Quote Share this post Link to post Share on other sites
*Glenn* 854 Report post Posted September 20, 2009 The sensor must match the DME to operate correctly. Getting a remap by Gavin will achieve more Quote Share this post Link to post Share on other sites

Let me know Jase It is also the same with Silvias. You have to map the ecu or get an aftermarket one to run an R32 or Z32 AFM on a SR20. Quote Share this post Link to post Share on other sites
