Thread: At my wits' end with Atomic EFI

    So I installed a MAP sensor straight to manifold vacuum. I tuned the map and timing table myself, trying different tables & settings. It didn’t help at all. I don’t use the pills. Is there a chance that this intake won’t work efficiently with this EFI?

    Which intake are you using with this?

    I believe that's a single-plane intake with relatively long runners. If so, this has shown to be an issue with the throttle body, particularly at idle & startup. This type of manifold affects the MAP reading due to the way the air moves through the manifold. It's preferred to use a dual-plane intake with short/standard runners.
