I was having an issues with my car dying when I came to a stop because of the VSS. I recently got my VSS hooked up (but reading high) and now it want's to surge when cold starting and when coming to a stop. I tried using some Russ K Base Idle Airflow .cfg but it didn't seem to work for me. I was reading it could possibly need adjustments in the throttle cracker/follower but since they are based off the RAF I shouldn't touch them until I assure that they are correct. This motor is a complete stock GEN III 5.3 with 80lbs injectors. The cold start is not included in this log as I tried the Russ K .cfg and never safed it.
The other issue I am having is that the car keeps wanting me to subtract around 20%-25% fuel at idle. When I do this and reload the tune it again will settle and want to subtract another 20%-25% of fuel at idle. It is just that my injectors are already running at the minimum pulse width at this time or should I keep taking away fuel and see what happens? They are fairly large injectors for my application.
Please take a look at my tune and let me know if you see anything odd. I am still trying to get everything dialed in as I learn but also stay on the safe side to not cause problems. I've done a few minor WOT pulls and it seems I need to start taking some fuel away to hit my correct AFR.
