Upgraded my 2.8 to a 3.1. Looking to add fuel at 4000 RPM and above, as above 4K it leans out and melts spark plugs. The VE table only goes to 3200 RPM. Where do I need to go to add fuel for 4000 and above?
Thanks

What ECM/Mask ID?
2.8 and 3.1 TBI are usually same size injectors, but I'm sure the bin is differant?

there is a VE adder table at 39E for dealing with fuel at higher RPMs.
not sure which XDF you're using, but this is the one i generated, has some more stuff than the common one.

Now it makes sense... VE above 3600 stays at the 3600 RPM value PLUS whatever is in the VE Adder table...robertisaar wrote:there is a VE adder table at 39E for dealing with fuel at higher RPMs.
