    That is what I thought, but in your documentation (pg 17 of COS using 2/3 bar) it indicates "several other STFT values may require adjustment:" {B4108} STFT Idle Disable. This value would either be...

    Ok - another question: why would you want to SFTF Idle Disable (B4108)? Don't you want SFTF since the O2s are giving feedback?
  3. LS1b semi-closed loop operation question (B3647)

    EFILive has the LS1b has the B3647 Commanded Fuel/RPM,which when set to 14.63, will cause the ECU to go into a semi-closed loop state using the O2 sensors to keep idle and part throttle AFR @ 14.63....
  4. Since I can't update my existing software, my...

    Since I can't update my existing software, my only option is to download. Will downloading delete any saved tunes in the bin folder? I am also assuming all license info is stored in the V2 interface...
  5. Yes, you are correct, I am using B3647 table...

    Yes, you are correct, I am using B3647 table which is the gasoline table. I think that if I specify an AFR of say 14.0 in table b3647 then the computer looks at what values are stored in the main VE...

    B3649 is a custom operating system that I am using in a GM 2002 Trans Am. It is shown on page 17 of the EFILive Custom OS upgrade tutorial documentation for LS1.
  7. How does table B3649 work if 14.63 is not used

    Table B3649 is a semi-open loop table that uses the O2 sensors to update the AFR only WHEN 14.63 AFR is inputted into the table. If you put any other value into the table it indicates that the PCM...

    When I click on Save, it goes to EFILive/Config. Should i save the file "Settings.dat" there? Also, should the file name be "settings.dat"? By navigating down on the V2, do you mean Scan tool/data...

    Greg,

    How will I know if the MAF is accurate to around the 70lb/min mass airflow value that I will need for the blower? Is the loss in resolution stemming from the scaling percentage employed to...

    Can EFILive change the MAF hard limit of 512g/s...

    Can EFILive change the MAF hard limit of 512g/s in the PCM? This would really be great because for those cars that have a blower, we would not have to try to scale everything or go to speed density.

    Scaling MAF for Supercharged GM LS1

    Has anyone tried to scale the MAF to be used in a supercharged application on a LS1 (with 12psi boost it does peg it early)? I would really like to increase the limit of 512g/sec but I think it is a...
  17. Idle A/F ratio rich, OK when put in drive, LS1 Trans AM

    I have a 2002 Trans AM, speed density tune, with 02 enabled (maf turned off). When the car is idling in park, closed loop, the A/F ratio is around 12.6 but as soon as I put the car in gear, the A/F...

    OK, so if I enable the MAF again, then the O2 & MAF will enable good AFR during my normal driving. When I get into the throttle, and the MAF gets pegged, then the PE table takes over (Boost VE table)...

    So when the car is running in closed loop, where do the LTFT values get stored (I assume that the PE table never gets overwritten). How does OLFA (Open Loop Fuel Air - I assume) When the engines...
