So I went Eurodyne stage 2, 91 this morning...
Lean code from 2nd O2 is still there...will email Eurodyne but I dont think there is a fix.
I will probably order a new o2 sensor next week when I order the colder plugs from ECS.
My advice to anyone is, dont go catless on the 2016+ cars (Was not a problem on my '15 GTI)
No one is disabling a "code", the tunes are designed to eliminate any CELs caused by running an aftermarket downpipe. That is not unsafe, it just removes that annoyance. If you need to hear that from a Tune provider for it to be valid, give them a call to ease your mind.
Your code is likely the computer saying "I think you're running lean because I'm seeing a high amount of hydrocarbons" because you have no cat. If you're not actually getting a lean code from the primary o2 sensor, there is no real lean running condition, only the catalyst monitors responding to WAY TOO MUCH EMISSIONS.
Put on a downpipe with a catalyst that claims no CELS, get a stage 2 flash that will remove the chance of CELs from running an aftermarket DP, or put on your stock downpipe. Not sure why anyone would run a catless downpipe in the first place, but that's just my 2 cents you probably don't want.
Getting the lean code sporadically again...with the new O2. The first O2 was fine....but who needs money anyhow?
I now think it may be the vband clamp coming a little bit loose everyday....will replace it. Another freaking 80 bucks.
The faults are triggered when the car runs in open loop so on cold start and light throttle. In general the lambda distance from the primary plays a role as well as how far the actual probe is from the exhaust gases.
Just rereading this.
Cold start, everything looks ok.
I kinda got used to this problem, as I have had it a while now. It is now irritated me so much I am going to drive around all the time logging it under the circumstances George describes.
