[mikeag96]

Running e33 on a custom jb4 map and this fault code just showed up today with about 1/4 tank of gas left.. any ideas?

I got this code after finishing the custom tune on jb4. Cleared it and it never came back.

I’ll get the code after filling up. Once I clear it, it won’t come back until I fill up again.

Too much E.

JB4 can't actually control fuel, mixture, or lambda tables. Clear it and see if it comes back.

If it doesn't you're fine. If it does, you need to use less E.

which firmware are you on? from the changelog for v21:

2) Adjustment to AFR safety system to prevent false alarm trigger.

Recently got a JB4 installed. On map 3 with e30. Noticeably faster. Would a custom map be worth it? If so, what’re the boost levels in custom map.
