Discussion and questions related to the course EFI Tuning Fundamentals
im having some weird issues with a surge type feeling also sounds like a mis-fire at the same time this happens at random rpm under 3000, i was wondering if i changed the injection angle to be injecting fuel in while valve was open instead of it all sitting on valve.
any help would be appreciated
What engine, what vehicle, what mods, who tuned it, post some datalogs
