Ive been logging my blm and setting now with my dfco off [i hope] and setting my ve tables.--- But i get the feeling my dfco isnt off, I was told to max out my dfco rpm min and max., and that should do it.---IF if it was off would you see a super lean condition when you let off gas ? [ wide ban reads top of screen] - IM using tuner pro and 7747 ecm.

 

no ideas guys ?????, as im having hard time getting lower map/rpm in line

 

When my DFCO kicks in my AEM wideband goes from "14.7" or whatever to "-.-"

 

not sure on that post ? It goes from 14.7 to ????

 

As I said, it reads " --.- " when DFCO kicks in. It goes right off the gauge and shows --.- to indicate that.

 

so if mine goes to max lean ,, when i let off gas then dfco is still not off when i let off gas. -- ive max out rpm min/max,, I wonder if maybe i have to do something with the map setting now ??

 

I guess there is know way of turning D,F,C,O --Off ??? tried everything i can think of. - any ides would be great

 

I guess there is no where to turn DFCO off ,, i guess ??? since no responce.--- yes or no would be great

 

Just set the CTS enable temperature high:

LD2F2: FCB 128 ; DISABLE DECEL FUEL Cut Off BELOW 75 c

°C = (N * 0.625) - 5

RBob.

 

thanks rbob, ill look for the stuff in tuner pro and try, --thanks again.--

 

I see on WB 14.7 on steady cruise and on foot off gas it goes rich as the sticktion of gas is pulled off the venturi/intake surfaces and enriches in log for a short while. Then I see that very lean spike. Now I run non DE(turned off/disabled) and I still see that result in log as fueling is now running off say 20 MAP at 3000 rpms fueling as an example .

 

yea, rbob, I POSTED late last summer on this and you told me what to do but i cant find thos you mention ??. --My tune is based off the ASDZ BIN and i use XDF FILE,,, 7747- MINE XDF ---Is there another xdf file i may need ???

 

I guess ill have too search some where else for a possable answer as to why i dont have thos settings [adress] in my bin to turn dfco off,, ??

 

per Rbob - 'DFCO disable below temp' is at address 2F2 in 7747 ecu

 

I think Carl sold his 1982 Z28. Sadly.
