Terry, would it be possible to use the JB4 with no bias on any inputs/outputs, solely as a boost controller? And would it be further possible to use the Req. Boost values (or wgdc) from the DME to set the boost control point?
In this way, would it be possible to run external wastegates either on a single or twin turbo N54, because the DME is getting the boost it asks for; just not in the way it thinks? And the DME could handle fueling/timing completely through the flash via Cobb/whatever. Understanding in this scenario that you'd be sacrificing any of the map-switching and auto-tuning benefits of the JB4, and you'd have to re-flash to change boost settings. Essentially, the JB4 would be doing nothing but replacing the idiotic stock boost control system on external wastegate systems.
Is this a mode that could be programmed and sold by you on the JB4?
