I removed my maf sensor and only have my MAP sensor. my fueling is over rich afr is targeting 10.6 instead of 11.2 on my fueling table. Since I cant scale my mass airflow anymore what tables do I calibrate to get my fueling in the correct spot on ecuflash and romraider. Tuning a subaru sti 2012

Stephanus,
That ECU doesn't have a traditional speed density model in stock form.
Swapping the ECU out for a quality plug and play standalone would allow for VE and MAP based tuning as well as other features
Some people use patched open source ROMs on the stock ECU with mixed results, but it's not something I'd be comfortable recommending.
