lnf ect/fuel

[cobaltssoverbooster]

i know there is an ect table we can adjust for timing but is there any tables we could have for adjusting the fuel to match ect condition. my lnf is stupid rich when its 30* but perfect once it passes the 70* mark....or am i missing the table completely

Try bumping up the ECT/spark table under the 30* area. It will help burn a little more fuel and smooth idle a little.

What about the IVT table, you mess with that at all?

Thats the warm up table. Its an open loop table. Dont know if the lnf has it though.

all i could do was adjust the ect spark as suggested but the fuel is like 11 flat on factory wb and external so its super rich. i did however find out that by leaving the dal at idle alone i was able to regain the afr back to the 14.5 area

What is the commanded afr when its at 11? If its above 11 then your ve or maf table (which ever one is being referenced at that point) is wrong in that cell.

it reads a solid 14.7 commanded but no matter how far i adjust the maf and ve table it never changes the actual. so since i found a spot where it stays 14.5 im happy its safe and leavin it.

Thats weird. Normally it should ramp from 9-11 (depending on temp) up to stoich as the car warms up. I guess we are not only missing tables but also arent getting all of the afr cmd pid.

well i just want controll over that function i know the lsj's get it, and since it is a commanded afr at startup i want to be able to adjust it. should help some in the future.

I wonder if they are completely done on our computers or if they will go back and unlock some more? Some start up tables would be good. Along with some more timing control. Ever try to advance idle timing to like 40*? it doesnt do exactly what you comand due to some other tables.

i idle at 10* but the main sparks at the load.xrpm value is commanded 25*
