Lean Condition? Trim Pegged out? -
05-11-2020, 02:53 PM
Hi team,
Been recently getting booted into Safety Map 4 due to lean AFR. Thought maybe the O2 sensors were getting fowled since I was getting "2C7B Lamba probe behind converter 2, signal" Have replaced the bank 1 and 2 post O2s, still getting booted to Map 4 for lean AFR Looks like my Trim is pegging out at 50. Thoughts? Running BEF for Hybrid Turbos, Map 1 91 Octane Upgraded IC and DP Fuel It Stage 2 Bucketless Recent data log attached. Booted to Map 4 just after this pull. Thanks for the help!

There isn’t a pump flash for hybrid Turbos - so you are likely using the wrong flash.
If just using 91- load the PUMP Stock turbo flash. Log map 1- see if that helps trims / AFR Home of the JB4 the worlds most popular turbocharged tuning system!

Right, my bad. I've been running map 1 and haven't been logging for a while so I've forgotten a few names etc
Last BEF was Pump. I haven't changed any settings since then, everything was running great, was even getting good results with Map 6 and 7 per your guidance. Then recently I've been getting Safety 2 in map 1. As I said, thought it was the O2 sensor based on the code, but after putting in new ones and resetting the adaptations, I'm still getting Safety 2. I'll double check my settings and BEF, but as far as I know I haven't changed anything

I’d do an o2 reset see if that brings the AFR back to normal at least temporarily- if they start to get wonky after the reset (or nothing changes)- you’ll know the primary bank 1/2 would need replacing Home of the JB4 the worlds most popular turbocharged tuning system!
