Tuning for Increased volume
Hello
I'm hoping someone can lead me in the right direction.
My current chip was modified for top-end work. I'm still running this same chip with what is now a 396 bottom end. (was a 350)
I'm a experiencing pings when rapidly pressing the accelerator. (WOT at full load)
I have all the software and hardware to burn and modify chips. The questions is, what's the best approach to tackle this issue?
Thank you
Hank

Change the value for cylinder volume in the ECM constants
Maybe remove some timing in the upper 90-100 kpa regions.
Add some fuel in the PE% change to fuel/Air ratio vs. RPM table.
Adjust your VE tables according to BLM values.
Verify changes through road testing and Dyno.
