  1. LTFT desired values for idle, light throttle, WOT

    Hello,

    I am not sure what the desirable long term fuel trim values are
    for (manual transmission, 2000 LS1 engine, F-body):

    1. car fully warmed up, car at idle for several minutes
    (when...
  2. Q about mixture menue: Hot PE vs Normal PE table

    It is not clear to me when, in the fuel mixture menu, the hot PE table is used. Clicking around it looks like it would be used only above
    ECT = 255 F, a condition which never exists unless the...
  3. Seeing identical values for MAP and MAF readings

    Hi,

    not sure if this was covered in the past:

    I noticed that while logging MAP and MAF (lb/min) both
    have identical values under all conditions, for example
    at WOT both have 29.8. I...

    conversion of gram/cyl

    I find the gram/cyl scale for the spark tables not very
    intuitive. I worked for a long time with lb/min.

    Is this conversion right:

    40lb/min of air at 6000rpm -> 3000engine fillings with air
    ...
  5. How is a larger throttle body accounted for?

    I am not sure how to tune for a larger throttle body which would have
    more flow for the same throttle angle as stock.

    Thanks,

  6. Prior to installing V7.2.2 - registry modification?

    I suppose it would be useful to know what to look for -
    that is what should be the numbers for spark, a/f, etc.
    during throttle changes,
    and then compare to what one gets actually.
    Once the...
  8. Crisper throttle response with tuning possible?

    I am happy with my tuning so far for the most part.
    However, I am wondering if there are specific tuning
    steps I can take to make throttle response crisper,
    both from idle and when at part...

    Blacky,

    I used lbs/min for years and know the numbers at different
    conditions off the top of my head - going to lbs/hour now requires
    dividing by 60. Flow of 2400 lbs/hour is 40lbs/min which is...

    I have been thinking about how to adjust the VE table based

    a bit...

    joecar,

    that's what I thought - there is more flow rate at idle than there is at
    WOT -> of course this is compensated for by the pulse width actually
    applied to deliver the right fuel mass into...
  12. Injector flow rate table - clarification sought

    Just wanted to be sure about the injector flow rate table.

    It shows injector flow (lbs/h) as a function of manifold vacuum (inHg)
    As the vacuum increases the flow inceases because the total...

    Blacky,

    thanks for the clarification. I had added my name in the
    registration field assuming that this was a common registration.
    It works now after leaving it blank.

    Thanks for the explanantion. The two included PCM licenses will obviously suffice in my case. I'll put the third PCM on ice for study by future
