Start-up Fuel and ISCV Tables
For 96530706 Try the above explanation using tables "Post cranking Transient enrichment vs coolant temp #1 and #2 "
these add fuel after cranking and decay over a few seconds per mrfred's explanation. I think you want to add time so that it continues to add fuel.
change the values in table # 1 for 45- 122 degree temp so that they are 120 or more tapering down ie 45= 120 etc 68=100 93= 80 122= 60. Leave the rest alone. Test and see if that helps.
If not then do the same for Table # 2
Test and see if it helps

Spent 4 hours in the car just fix that idle. The Idle wont go past 1000 rpm what ever steps i use , upon load with a.c and lights on it drops to 800 - 750. AFRs are like see saw, back n forth. Give some throttle and it goes lean and then back rich. As soon as i take rpm to 1300 every thing gets better.

The data looks the same as the 96530706. The temps however are displayed in Centigrade, but 96530706 is in Fahreneit. No matter, just change the data on teh right to what i suggested and TRY it.

Sorry for the revival of this old thread but does anyone know if the Post-Cranking IPW adder #1 and #2 tables can help richen AFR after the car has been started?
I have noticed that whenever my car is started when warm (operating temps) the AFRs are a little lean (high 15's to 17ish) for a few seconds. So i wonder if i were to increase the ms in the desired temp ranges if it would help richen it? Since they are 2 tables is one for the main maps and the other for alternate maps?
Thanks in advance
