Expand VE table to allow boost

Post by Breathial »

Hello, all, been lurking for ~2 years now, working on '99 Vortec 454, adapting 6-71 GMC blower to use EFI intake, 0411 computer, 4x reluctor, etc.

I'm using the 2002 Chevrolet Express Van L31 5.7 liter 4L80E bin as a base file to modify...

I've tried to make sense of the Hex editor, to understand how to increase Main VE Table to include MAP readings up to 0.5 BAR (7.2 pounds of boost). Would like to continue increase MAP readings of 5 kPa per row, i.e., 10 additional rows, from 110 to 150 kPa. Still trying to get this worked out while the engine is at the machine shop...

As I said, I'm completely lost on how to figure this out, there seems very little discussion on this issue... :oops: Can anybody help? If the bin file Main VE table could be modified to add the additional rows on that generic file, I can do the rest...
