O2 Sims, in my experience, never work. I can send you a programmer that will read & flash your ECU and we can look at switching off the P0420 and P0430 that way. You won't 'lose' your tune, and who knows, we might even be able to improve it a little bit

Long time no update, but these cats are still giving me a load of headaches. Starting to regret messing around with things. Didn't expect the Christmas tree of codes every 50 miles.
When I went into his shop, I was popping these codes with their top of the line $14,000 machine.
P219A
P219B
P0137
P2096
P0420
P0430
He cleared the codes, and then my OBD II is showing my these after we tightened everything up and went over everything:
P219B
P0430
P2096
I cleared the codes last night and in 30-40 more miles I'll see what pops up again. My guess is that at least a few will still show. The car has no clue what to do with these cats without a tune.

I recently put on those o2 sims and then had to take them off because I was getting those codes too. I took the sims off and the only remaining codes left were the p0430 and p0420 efficiently codes. After they cel came on, I cleared the codes with my scanner, and it went away for good. It has now been 1 week and I havnt gotten any check engine lights. Hope to god that it doesn't come on again. I guess my ecu adapted after various code clearing sessions. I think havin a tune has really helped integrate these cats into the sequence. Next week my pulley goes on and then I am done with my car in terms of mods.

Are you sure they did not install O2 spacers or 'cheats'?

Think you guys have Denso. We can switch off the cat efficiency codes with an ECU Tune - handheld programmer that you keep.

Is this possible without changing the tune? I have an ETG tune (5.0 XKR) but would like to just have the cat efficiency turned off
#73
Yes, we can go in and just change one parameter. However, it's not really much difference from our point of view, and I believe based on some F-Type files I have seen that we could improve upon your tune anyway

No spacers or cheats. Took a good look at the install at my friends shop and short of a few things that needed tightened up it looked all good to go. Even with everything snug and fit I'm still popping the P219A/B codes, although it seems to be only those two codes for now.

Happy to help if we can.

It's been mentioned many times but i'll put here again, do not put spacers/extenders on your downstream O2 sensors. The downstream sensors are also used to manage fuel trims, attempt to trick the sensors and you will have a heap of trouble...
Like this stack of codes...
P219A Bank 1 Air-Fuel Ratio Imbalance
P219B Bank 2 Air-Fuel Ratio Imbalance
P0137 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2)
P2096 Post Catalyst Fuel Trim System Too Lean (Bank 1) <<== hello!
P0420 Catalyst System Efficiency Below Threshold (Bank 1)
P0430 Catalyst System Efficiency Below Threshold (Bank 2)
If you just fit cats and do nothing all you get is the P0420 and P0430
As for why the P219A and P219B are still sticking around, you probably need to do a "hard reset" aka leave the battery off for a while, or do the "full vehicle reset" routine with SDD to get rid of them.

I just fit the cats and did nothing else and got my laundry list of codes. I have not done anything at all to the 02's. From your post you seem to be accusing me of doing something to them listing the codes that I had pop up, when I've said several times nothing was done other than the cat swap. It's annoying when I have said before that the only thing that was done was a CAT install which was perfect sans a small leak which was buttoned up.
The reason I'm posting here is to give someone else who may run into issues a chance of fixing them, or at least something to compare to. I'm hoping to eventually not have a CEL on every 30 miles.
For now, I'm still getting P219B's and a historical P219A. I'm okay with these until I can get some sort of tune.
