yupp makes sense. so between 12-14 afr is safe depending on rpm? Also timing what would be a safe place for timing under boost, im curious because iv seen some engines come into the shop that have been detonated because of too much timing.

Between 12 and 15 is good - you will see some spikes here and there from on and off the gas... I set up conservative timing in the base tune we did. The COS pulls timing under boost based on boost, so that is set already... Always better to start timing low and raise it on the dyno when you can see what it is doing to torque/power...

hey umm what do i do with this calc pids.txt file?
hey in my datalogger i dont have afr from lambda or anything ben related. what do i do?damn noob i know.
You put the calc pids.txt file in my documents/EFILIVE/V7.5/user configuration folder. Then you will have the pids you are missing... I'm not going to be able to help more until tonight - no tuning software at work... I LOL'd at the chair wielding smiley!

After you copy the calc_pids.txt file to the User Configuration folder (see what BLK02WS6 said in post #105), you restart the scantool and you will now have the following pids:
CALC.WO2BEN (correction mulitplier based on wideband)
CALC.LTFTBEN (correction mulitplier based on LTFT's)
CALC.SELBEN (correction mulitplier based on LTFT's (CL) or wideband (OL))
you can select all of them, and then use the one(s) you need;
each of those pids is dependent on other pids (on the PIDs tab, on each of those pids do rightclick->More Info so see which other pids you need to select).
Ok so i put the pid file into the user config file and it only gives me 10 pids to choose from on all pids. Any ideas why it would do this?
i figured it out just a stupid mistake...

Hey guys
I datalogged from my road to the highway. afr was alittle high so I didnt log much. I notice when idling, or have light throttle the afr is lean, when i get into a tiny bit of boost it smartens up.
first drive 427 turbo.efi427 cos base_0000 (1)_0001 jun 3.tun
Good call - it was lean... Here you go - try this one out...

hey, i only took my truck to the end of my road again.
It goes into a lean state when slightly on the throttle. when i let off its back to a safe afr and when i get into the fuel alittle and add boost it is at a safe afr.
here is the log,
