   In message <m0pz9lg-000AVPC at knuth.mtsu.edu> , you write:
 
| In case anyone hasn't seen it before (i've seen it posted to r.a.t),
| this is the basic equation GM uses for its speed density systems:
| 
| OT = (BPC * F/A * VE * BLC * DFCO * DE)/2 + AE
| where OT = Injector On Time
|      BPC = Base pulse constant
|      F/A = 1/(desired AF ratio)
|       VE = Volumetric efficiency
|      BLC = Block learn multiplier/128
|     DFCO = Deceleration fuel cutoff
|       DE = Deceleration enleanment
|       AE = Acceleration enrichment

Can we get a good description of these terms and qualities such as
how much enrichment etc...
