do you still have these bin files? before and after the work... should be easy to track down if you do.Back when I was a HPT customer the only way I knew to fix the problem, was to send the bin in and have them "fix" it.

When that happened, more then likely the car ran super lean. What I have noticed when turning the codes to X Not Reported, the car didn't fault into Speed Density and still used the MAF table for partial fueling. I have mine in all the cars set to 1 Trip/No MilOriginally Posted by jnorris

Could someone please explain this? Is he turning off DTCs or actually changing the pcm (0,1). This reminds me that I am - the analog man.Originally Posted by jnorris

TOL (thinking out loud):
This means calulated engine torque is around 150/170 ftlb at idle...!!!
This points to the calculated airflow being wrong (i.e. VE table or some other table is off or way off...).
Just a thought.
If the MAF is unplugged/disabled for SD tune, the pcm cannot get an accurate calculated engine torque. So, in SD mode how does the pcm compensate for this and figure line pressure?Originally Posted by joecar

I'm not sure (...I never am any more... ), but I suppose engine torque is calculated from calculated airflow (and other things), and then PCM uses calculated torque to lookup base line pressures, and I don't know if this applies at idle.Originally Posted by Ladyredhawk
IIRC calculated engine torque is looked up in a table that is not visible in EFILive. Maybe we need to make it visible so you can make the PCM's calculated torque value mimic "reality".Originally Posted by joecar

Can you please send me your file?.
I'll make the change here for you to test with and if it fixes it we'll get some new 1998/1999/2000 cal files out with the fix available.
It's basically another enable/disable type table that looks to another pressure value if the DTC is set, in the 1998's the DTC's that will cause it to do that are TPS and MAF, in the 01 file I checked nothing will do it??. Thanks to all that let out some hints on what to look for, I always figured it was just the full line pressure faults causing it.
