I want to adjust my cold fueling in my bin, and i always read where it says adjust the A.F.R. , V.S C.T.S TABLE ? ----- The only thing ive been able to find is , O/L A.F.R. VS TEMP,? -- And it has a address of 045A, in tuner pro, with a 7747 ecm. ---Is this the same correct one to adjust for cold afr adjustment ??

 

For open loop AFR there are two tables used. One is vs vacuum, the other is vs CTS. The one you listed at $45A is the CTS based AFR value.

The vacuum based table is at $41E

The code does a lookup on each table and adds the values together. The result being the commanded open loop AFR (along with after start adjustment if any).

Thanks Rbob, The reason im asking is i want to lean out my cold fueling as when its cold, and you attempt to give it gas it falls on it face, with to much fuel [you have to feather the gas on accell when cold to avoid it] ----- Also if i put my pump shot at stock settings it does not do this, but then im lean on accell when its warmed up and get lean back fire in intake.---So i was aiming at cold fueling [choke] ????? -- Im a crossfire, working off the asdz bin .

 

heres what i got,- When veh is warmed up, it has a pop thru intake [wide ban showed this lean] last year when it worked ! --- But when veh is cold, has a major rich condition if you get on the gas. [have to feather the gas] I can even stall it with too much fuel on accelleration. ??. Ive raised the pump shot up [map/tps, to get rid of lean condition which helped some ??, BUT IF i leave it at stock setting, [asdz bin] the accelleration flooding goes away ???, Im just lost as to what to change in the bin to possably remedy this. - Ive leaned out my cold fueling, and it had no affect.
