Did a search for this, and to my surprise, didn't find too much. What I did find wasn't very conclusive.

I looked through a $32B hack, and found this...

; >>> Air Injection Managment Tables & Param's <<<

;**************************************************
LC305: FCB 00 ; if in Pwr Enrich for >= this time then divert Air
; Max Air to ports, (Sec) E * 10
LC306: FCB 10 ; Divert if If RPM Cont > LC30B FOR TIME > this
; Num = Arg * 10, (1 Sec)
LC307: FCB 170 ; If Filtered o2 > 0.752 vdc for LC309
; Then divert
; Num = Arg * 226
LC308: FCB 56 ; If Filtered o2 0.247 vdc & in closed loop
; > Then divert
; Num = Arg * 226
LC309: FDB 0200 ; 20 sec Rich or Lean o2 Divert timer, (sec * 10)
LC30B: FCB 177 ; Divert if cont > 4000 RPM & time >
LC30C: FCB 10 ; Enable air to conv If > 1 SEC since last neg delta LV8
> is <
LC30D: FCB 25 ; If LV8 < 25 then Divert
LC30E: FCB 100 ; If LV8 > 100 & MPH > Divert Air
LC30F: FCB 60 ; If > 60 MPH & LV8 > then divert
LC310: FCB 64 ; Enable air to conv if in open lp & 100 Msec Drop in LV8 <
64
LC311: FCB 73 ; If Cool T < 14c, (58.5f) then divert
LC312: FCB 254 ; If in Open Lp => 25.4 Sec after
; closed loop then

Now, I don't have a testbench to try this out, but I'm sure some of you guys have tried this at some point. Raising line 311 to 254 would disable AIR correct?

 

Yep, setting the temperture to the max will force divert.

Thanks. I wanted to be sure, since I didn't have a means of testing it easily right now.
