    lmao...

    Garry - Hill's and heal-toe. I can hit most every spot, and I don't worry about the rest.

    Hill's and heal-toe.

    Never tried the heal-toe method. Not sure if the missus would like it. Have you tried the mistle-toe method. Works great under trees but not good on hills.

    On a more serious note. After having completed getting my BEN's real close I transferred the VE calibrations to my original tune and set about disabling the MAF and going out to log my LTFT's to see how they looked. I added the two PID's for LTFT and started logging data. The problem is, I can't get any readings. My LTFT's are showing zero. I know the LTFT's are enabled in my tune as I checked the parameter. Since this was my original tune and the only things I changed were the VE table values,spark low octane table & disabling of the MAF why am I not getting any LTFT readings?

    Vet,

    Did you enable B3801 and reduce the temp on B4205...?

    B3801 is enabled and B4205 is where it was before. B4206 is disabled also (use 02 with open loop table). Should this be enabled?

    Is it possible that the 02's are just not working and that's why I'm not getting any LTFT readings? When you disable the LTFT does this shut down power to the 02's or is it just that the voltage is not reported back to the PCM?

    When you disable LTFT's, the O2's are still powered (my LC-1 is powered this way)...

    the PCM just ignores the O2 voltage output, and assumes the value of zero for the LTFT's.

    O2s aren't ignored with LTFT's disabled, just long term learning is disabled. O2's are still used for short term fueling, aka closed loop operation, assuming his enablers allow that to happen.

    Justin, yes you're right, just the learning is disabled. I think he has both long term and short term learning diabled also.

    Time to get more coffee....
