Newbie w/cam swap idle issue
Hello-
Over the couse of the past year I've been customizing my 1999 GMC 4x4 stepside. This past week I installed a Z06 cam. At startup the engine idle speed swings from 2000 rpm to 500 a couple of times then dies. After a couple of these attempts, the engine finally settles down around 800 rpm.
I'm new to using the efilive tuning software. I've made some program changes in the past and I have looked over the idle tuning tutorials, but a little overwhelmed by it. Are there any changes I can make now to get idle somewhat controlled at startup, till I can take more time to tweak it in?
The truck has a 5.3L engine with a Radix Magnacharger, OS is 09379910, transmission is a 4L60E. I am attaching latest tune file . Any help would be greatly appreciated! Thank you,
