Default b58 port injection? - 05-08-2019, 08:57 AM

I've searched a little and have come to the conclusion that the b58's fueling upgrades is limited currently to WMI, LPFP, and TBI. We saw the coming and going of the TBI method on the n5x/S55 platforms and replaced by aux port injection with a "sandwich plate" between intake manifold and head. Is there an obvious reason this hasn't already been attempted by Fuel-It! and other companies? On the n54 platform, port injection aka "PI" is controlled either directly by JB4 or by primitive third party "AIC" units. If I'm not mistaken, the AIC units only need access to rpm, boost, power source, ground.

What's the hold up?

Fuel-IT is testing on a CPI solution, and there is also our WMI kits. Port injection in the traditional sense isn't practical due to the manifold design.

The JB4 supports and maps both of the above solutions.

What about the manifold design would prevent such a sandwich plate? Awkward fuel lines/fitment of fuel rail/injectors?
