Well thinking about the "new ecu" idea, i think that it would be very limited in what timing curves that it could produce. With many people here running different turbos, and custom setups, the "new" ecu may not give enough room for adjustment. This is where the adjustability, and versaility of the J&S can come into play. If this unit does indeed let us run a "user adjustable" boost pressure point for open loop operation, that will be THE answer to all of this. We can then adjust the amount, the exact psi, and when to pull timing when in open loop mode. IMO, thats what we need. Yes??
