a2z24 Posted May 30, 2016 Share Posted May 30, 2016 I've got a issue I can't track down. New to tuning but got a pretty good understanding of most of it. According to both the manifold AFR and my downpipe innovate wideband, I'm running about 13.2-13.6 AFR at idle and same goes for low load cruise situations. Even on the CL compensations, it should be looking for about 14.2. Is there a map I'm missing for this? 2007 spec b Stock intake w/ k&n drop in GS EWG up pipe w/ tial 38mm GS Intercooler Invidia downpipe utilizing rear 02 port for innovate wideband Link to comment Share on other sites More sharing options...
solidxsnake Posted May 30, 2016 Share Posted May 30, 2016 What are your fuel trims (AF Correction and AF Learning)? If those aren't pegged at a large negative number, then your car thinks it's hitting target and it's time to look at the tables for compensation or similar. If those are pegged, you could very well have mechanical issues. Link to comment Share on other sites More sharing options...
NSFW Posted May 31, 2016 Share Posted May 31, 2016 Others have reported running rich after removing the rear o2 sensor. If you put it back, I bet that solves the problem. I had a WB bung welded onto my Invidia DP bell mouth. Link to comment Share on other sites More sharing options...
a2z24 Posted June 1, 2016 Author Share Posted June 1, 2016 My live view shows about 8% max af learning. I do have my rear O2 removed. The downpipe does have 2 bungs but I chose to utilize the stock location for the wideband as to not burn up the sensor. Guess I'll re route the factory rear 02 plug to the Bung behind the turbo n stick it in and give that a shot. Link to comment Share on other sites More sharing options...

When you read manufacturers saying 18" after the turbo, keep in mind that some Subarus have an extra two feet of exhaust tract before the turbo.

a2z24 Posted June 1, 2016 Author Share Posted June 1, 2016 Swapped the rear o2 back into stock position. Moved wideband up to bell mouth. AFR is perfect now. and Learning is around -.78 ish. Amazing how confused the car gets without a 02 sensor. I appreciate the assistance guys Link to comment Share on other sites More sharing options...
solidxsnake Posted June 1, 2016 Share Posted June 1, 2016 Which learning is at -.78? Did you reset the ECU? Because just because the number is low now doesn't mean it won't change more, FYI. If you reset the ECU, all four of your learning ranges start at 0%. Link to comment Share on other sites More sharing options...
