Had my r18 tuned recently, and found out changing 2 step and obd2 stuff doesn't work.

2 step will always default to stock limiter of 3800-4000
Disables kind of work? Disabling primary o2 sensors doesn't throw a CEL but it stops my wbo2 from working. Haven't tried any other disables

Also, I've made sure that my cals are uploading properly, and they do seem to. So I'm not sure what I'm doing wrong

ECU: 37820R1AA040M1
Software: 37805-R1A-3050 (this might be something)

What are you changing the 2-step to?

Disabling primary O2 would stop the primary O2 from operating, so sounds like it worked.

I tried different numbers with none working. 4700 restart, 5000 limit was my first try, didnt work. Tried a lower number, 2500 restart, 2600 limit. Didn't work.

And for the primary o2, shouldn't it throw my car into limp mode if its disabled?

I'll take a look.

No. It just won't use it for feedback because it's disabled.

Any updates? Also do you mind showing me the table dropdown list you have where the ignition, wot maps, etc are located?

No updates.

At the top left of the tuning table (Left side of the toolbar above the table) is a square for the drop down. Click it.

Any chance the R18 will get a fix for the 2step? Or will it just be shelved due to the new 11th gen coming out?

It's still on a list of things to do.
