N55 DPFIX!!
A little good news. BMS is BETA testing their N55 plug and play downpipe fix. It connects between the oxygen sensor and the DME and alters the signal as needed to keep the DME happy. This means readiness testing completes, no codes are stored, proper primary lambda calibration, and potentially improved idle for those of you using downpipes. Pricing will be $135.
Keep in mind this product is intended for race cars only and not legal for use on pollution controlled vehicles.
