Engine codes P2096 and P2098

Jordo! · 09-26-2016, 07:47 AM

There's a menu for turning of DTC codes in uprev -- make sure the one for 2ndary O2 is turned OFF.

See further p. 16 of http://uprev.com/UpdateFiles/softwar...er%20Guide.pdf

However, I would also make sure that you really aren't running too lean. Probably just the lack of cats, but, you might still be running a tad lean given the improved flow.

There's not many choices we have when we have 3 breather mods.... think you'll find here on the forums once you go beyond 2 breather mods you'll need a tune to make things right. The ECU can adapt somewhat but it's best just to do it right and get a tune.

I know that this has been almost a decade ago (crazy how time flys) but did the tuner delete the rear O2's or did he just do some tune wizardry to fix w/o deleting rear O2's (because from what ive seen, especially on newer cars, if you delete the rear oO2's then you still get an SES light) was just curious because I have an AAM CAI, Motordyne ART pipes, injectors and a Z1 ECUTEK tune, and im still getting this
Luckily did my state before hand, just wanted to try and get rid of the the SES light asap
