2018-19 Front O2's

[mikengail]

Need to replace the driver's side front O2 on my Gen3 Coyote A10. Any brand better than the OEM replacement? Any recommendation for a vendor? Thanks...

OEM Ford, White Bear Lake has a good online store.

I used NTK on my 2015 after burning up multiple 02s. Not sure if they're making ones for the 18+ yet. But after the switch, I no longer had any issues.

How did you know it needed replacement? Code?

P0430 code. I don't get it any longer. When I was going through the process of finalizing my E70 tune, I would get this code frequently and clear it with my tuning device. Of course, it would reappear, until we eventually got to the final tune adjustment. Now though, my AFR's are extremely rich all the time staying between 10 and 11. I just want to make sure that the upstream O2's aren't causing any problems, before any further tuning adjustments. What I also really need to do is change the placement of my front O2's on my headers to an angled down position relative to the ground so that any moisture buildup drains out of the sensor...

Just get them angled and call it a day. You'll save yourself from the headache.

P0420/0430 are cat efficiency codes, related to the cats and rear O2 sensors. Not the front O2 sensors.

An AFR of 10:1 on E70 doesn't sound all that rich. What is the target AFR?

 

[mikengail]

Perhaps, I'm not familiar enough with AFR's on an NA Gen3 E70. This is not WOT. It's idle and cruising.

I'm not either so I'd run that by your tuner first and see what the target AFR's are before replacing any parts. Beyond that if your code is P0430 you should be looking at rear O2 sensors and even beyond that, why your tune has the rear O2 sensors reading at all since you have longtube headers.

This doesn't always stop 02s from burning up. It helps be its not the end all solution.

You're right. You run the risk of burning out sensors when using different fuel. However, angling the sensors is the only sensible, proven solution as of now. I'm still waiting for a permanent fix, lol.

Angling the front O2 sensors won't have any effect on a P0430 code.

Well, my tuner said that the targeted AFR for my combination is 10.7 on E70, which is right about where I'm at. No worries then. Thanks for all of the comments.

Going to a dyno day this Saturday. My last dyno at 2k miles got me 470rwhp at 5530' altitude. I have 12k on her now, so I'm just trying to see whether or not there will be much difference with her fully broken in. Weather will be a little cooler than last time as well. I know that SAE is supposed to correct for altitude, but that formulae becomes less reliable beyond 3000'. Also, I had some warranty work done on the 10r80 with the replacement of the entire front support assembly. Known problem with the early batches of the '18 GT's. Feels much tighter now. Should be interesting...

What gear did they dyno in? Your power seems about right (470-475whp for A10s with longtubes and E85 vs 485-490 for manuals) but torque seems low. Should be more like 430-440

I don't recall for certain. I think it was 7th? I know that there have been problems with the 10r80's slipping in 7th on high horsepower forced induction applications. Realistically, I'm guessing any difference would be within an acceptable margin for error anyway. Lol...
