I've read a few threads where people have mentioned this, or having a low/mid/high type switch but never heard how they get on. Its really quite a tricky system when you dig into it with some aspects definitely targetted for emissions, however its also attributed to its nice thick torque curve at lower RPM also. More interestingly they can essentially run without throttle bodies at all and the OEM config implements this to good effect. Read the other day (can't remember where) that at about 13% throttle and upwards they run near wide open throttle blades with the VVEL doing the work ... they snap them closed when you come off the throttle to provide vacuum.

@Zedute I am going to run the stock ECU for the time being as the goal (and budget) is to get mobile first then see where things are at. Unfortunately there were no eureka moments and all aftermarket options came with a significant cost and subsequent tuning effort (i imagine). The Nexus looks like a really great option, especially in the EH as it will take care of all power which isn't in the car at present ... supports twin DBW out of the box also. Are they still using the factory VVEL module with the Nexus like the Elite does ? Seems a bit of a cop out but can totally see why they went this way. I'm working on running my engine on the ground to prove out my wiring 'solution', spent way too many nights getting to grips with it all from the Nissan FSM's !! Amazing resources to have available ... wish my mysterious BMW had the same

@Drexal Did you ever make and progress with this ? I was just on chat support talking about the exact combo you have (VQ37 and G4+ Thunder). I pointed them towards the Haltech documentation which shows how they deal with the VVEL control, with the factory module over CAN by the looks. I am just about to start my project (VQ37 in E46) so need to solve the same issue ... hoping to go with a Link (supports 2x DBW but no VVEL) over Haltech (supports VVEL but only single DBW). But would need to swap to cable throttle bodies on the Haltech.
