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.

Ofcourse it's priced $50 bucks more than the n54's.. I hope the price of the dps won't increase since the Dp fix is coming out..

So even if you have a JB4, this is still recommended? Is that right? "Sorry Noob Here"

Question

{flame suit on!}

Sorry guys - I haven't been on in awhile and should do a search!!

For a noobie wanting to eventually get a DP once my warranty is up - what exactly is this product and what's the purpose of it (ie, what is it fixing). I'm gathering that guys that have a DP installed might be experiencing IDLING issues? Or other issues that this module is supposed to help a ton with? Let me know. Thanks Guys! -WoW

They are still doing BETA testing and have not expanded it beyond local customers yet.
