So i temp. hooked up my Wideband O2 sensor, disconected the ECU's one as i only hace one bung till i get my new DP in.
Im running Pig rich, is this just the fact my o2 sensor is not leaning out the mix, or would it be the Walboro 255 ?
Makes me wish i had the TD05 on anyway...

Hmmm, thats interesting.... What are you reading for afrs?
I have a zeitronix that simulates a narrowband to the ecu.... I would try to get that stock o2 in there as well and see if that changes anything....

Belive it's a PLX Wideband, it's reading just RCH on the gauge and is all the way clocked at 10...

That's your reason. The ecu has no live feedback of it's fueling, so it errs on the side of richness.

Figured all it be seeing was O2 rich air and would just be pumping gas in. that was my thinking, just wanted to check.

are you using the PLX's narrowband simulation?
