Working on a cammed 05 5.3, tuned the maf and ve seperatly in ol using wb02 with everything +-3%. Set tune to CL with ltfts enabled and the afrs are way lean and when it goes to closed loop. Wot is fine still. Cruising is okay. Idle is weird. Stft are -2 to 3% in the short log I ran. Nb02s look lazy at idle and if I highlight and average them they are in the higher 500s. When restarting the truck its in the mid 14s until it switches over. Switchpoint is at 450mv across the board. The tune is work in progress but I wanted to get it running decent at for a friend. I will post a log and copy of the tune when i get a chance to log it again and set up my pids and dash alittle better. In tge mean time, any thoughts?

1st tune- open loop ve
2nd-ve ol
3 final tune trims enabled
4.log before my battery died on the computer (ntk wideband disconnected) afrs were from his aem wideband which I didn't have any expressions for which is why I used my ntk for the tuning

Tune isn't finished but just got it so its driveable. The tune was originally a tune from black bear but it was kind of a pain going back and forth and waiting for revisions so I decided to tackle it myself, so most of the trans tuning is theres.

I didn't do any calc vet etc, figured the results would be the same in the end using the wideband and tuning seperatly in OL

I'm still looking... so FINAL_TUNE.ctz (https://forum.efilive.com/attachment.php?attachmentid=18751&d=1440749938) is the current tune in the PCM...?

Can you log these pids instead, see attached, copy attached file to Documents\EFILive\V7.5\PIDs

and then on PIDs tab in scantool, open that file (to select those pids).

Do you want the truck still set in closed loop? Just as it is?

Will I need to make some calc pids to be able to use these?
