Car: 89 Turbo Trans Am and lots of non-3rd gens Engine: 231 SFI Turbo's, LT4, LT1 Transmission: 2004r, 4L60E | How to lean out Cold Start Open Loop on $8D ?
There's 1 table I see thats directly related to "Open Loop" and Coolant temp for "cold" starts, called "Open loop Change to A/F vs. Coolant Temp" in TunerCat.
If I want to lean out the mixture a little for cold startups, is this the table I should be tweaking and how?
Current values are:
85.7
51.0
20.9
10.7
6.0
1.0
1.0
1.0
1.0
1.0
1.0
1.0
1.0
1.0
1.0
1.0
1.0
It changes to '1' at 20 degrees C, which is 68 F. My guess is making these '1.0' a negative number would do this, can that be done or is this correct?
I'm guessing the colder it is the richer the mixture will be with this table. | | |
