Question about WOT table in $8D bin

[NRG]

Well I think that's excellent info Mark! Thanx a lot ! I'll go try to see what GM had in mind by using the formula to calculate the values from the stock .bin.  I'll report back with my findings :)

  Hi Edmond:  I will try and help you.
  This info applied to 165 ecm, using 87-88 code for F&Y body.  It "may" be the same for your app, if not it will
  hopefully send you in the right direction. This info is being carefully typed just like it says in my MT manual.

  "WOTR
  This table is percent change to Air Fuel Ratio used at or near wide open throttle conditions Vs. RPM.  AFR is based
  on 14.7:1.  The values from WOTC and WOTR are summed to arrive at the WOT Air Fuel Ratio.

  Approximate WOT air fuel ratios may be calculated using the method shown below.

  For the selected RPM, suppose the percent change to Air Fuel Ratio from the WOTR table is = -5.1 and the percent change
  to Air Fuel Ratio from the WOTC table at the selected coolant temp is = 22.7, then the approximate AFR would be:

  1 - (-5.1+22.7)/100 * 14.7 = 12.1:1 AFR"

  If you have diacom it will show you the "Commanded" AFR.  Keep in mind that this is an estimate.

  I am running a commanded AFR of 12.0:1 and I am sure it is leaner than that because if I drop the AFR a bit leaner the car falls down
  and detonates, but 12.0:1 would really be too rich.

  HTH's

  Mark

      Hey guys. I got a quick question. What does the "WOT change to Air/Fuel ratio compared to RPM" table in TunerCat for the $8D definition file ? I mean it's pretty self explanatory but the numbers arent. Mine has both positive and negative numbers. What is the relation between these numbers and the actual ratio ?
