Here is what has happened. gen 3 ecm and all related sensors install on a 5.7 Mopar Hemi..(called Hemitronix conversion)
Car was running very well with LTFTS adding +25% fuel. Good power,idle,throttle response. Has been on the road all summer
Decided to tune VE to get ltfts in line.
Failed MAF and other fuel adders, added 15% to VE Primary ,Reset Ltfts . Engine ran very lean ,hard to keep running
Added another 20% to VE and still lean.. Added 40% still lean. rechecked fuel pressure Just over 58psi. no intake leaks or exhaust leaks
Have my LM1 hooked up. narrow band o2s disabled for tuning purposes. Attaching tune file and log files, I tried to upload the 40% log
but it would not upload. still ran lean .didn't make much or any difference. Was hoping some one could check these out before I put the old tune back in and enable the narrow band o2s etc. Still new to HPtuners so I apologize if it takes me a bit to figure things out
