Pure Turbos stg2 (similar): Help with AFR in base map
Please, can someone help with a log analysis?
Car: BMW 335i 2011 E90 N55 PWG Upgrades: Hybrid turbo (made in Brazil, but similar dimesions of a Pure stg2) BMS intercooler 5" BMS Intake Pure inlet pipe N20 TMAP sensor JB4 / bluetooth Problem: While runnig the base map (also made here in Brazil) the car runs fine, but as soon as i try to sustain higher boost lvls at high RPMs with jb4 map 6 the car starts to fail momentarily around 5000 RPMs. I beleive it is because the base map is aiming an AFR too rich for this engine ( in the log shows around 11.5, check the logs below ) Log: https://**********/u/alebler/dino-bo...18&zoom=24-352 OBS: in this log the car is running on a dyno and only with the base map ( JB4 map 4 ) I already saw some N55 engines with pure turbos with +-21 PSI logging around 12.5 AFR with E30 (similar to our gas here in Brazi that is around E25 E27,5) under WOT. Question: Can someone pls help to check if this AFR in the base map is OK or its too rich? |
