Importing a Fuel map from another product

Post by gjestico »

Hello,
I have a project running a Holley EFI system. I plan to swap it for an MS2 unit. The Holley VE map uses Lb/Hr for the values in its cells , But otherwise the map is laid out like the MS (Rpm on X and MAP on Y).
As I understand it, The Megsquirt table values are percentage units of the Req Fuel calc ? Any way I could equate the holley Lb/Hr units to that so I could get the Megsquirt VE map close right off the bat ?

If you really want to go that way I would fire it and warm it up on the MS and adjust the idle VE to match the typical idle AFR of the other set up. Then you will have something to scale with.
VE%(idle rpm/map) : Lb/hr(idle rpm/map)

Your probably going to use VEAL to correct the map anyway, so why not just let it do it's job on the standard map and save the messing around.
