Discussion and questions related to the course EFI Tuning Fundamentals
So I’ve done fuel pressure on the Y axis and battery voltage on X axis. Now for the short pulse adder the table is only 2d and cant modify that. Do I use my base fuel pressure to set the short pulse? Or do I leave it at 0? Is this a good option for the 1:1 raising fuel pressure with boosted engines, or do I leave it 2D the dead time and let the ecu compensate? Injector are 1700X ID and I used their supplied info for the G4+.
No one can tell me this?
If you want to use 3D deadtimes you need to use differential fuel pressure on the table axis - not fuel pressure. Provided the regulator keeps the differential pressure reasonably stable then there is probably not much to gain from using the 3D deadtimes.
As for the SPWA data it is in the link Plug & Play datasheet on the ID website: http://help.injectordynamics.com/helpdesk/attachments/4057295777
Yeah that’s what I did and I used the 400kpa data since my base fuel pressure is around 55psi. I’ll just use the 2d table then. Thanks Adam.
Good question I guess since it’s always been there I’ve been too lazy to change it
