Whilst the transition might be a little crude....

What about killing 12v to the secondary injectors, all wired as I mentioned,, 2 inj per cylinder pr ecu output, so fully sequential.

But then have the ecu turn on the trigger point to energise the secondary injectors..and then you'd have to try and adapt the fuel tables to suit, or perhaps at the same time switch MAP1 to MAP 2 ?

The transition may not be totally smooth though, but could maybe be done at lower loads so as not to affect racing ?


or Alex could re-write code to allow 6 x sequential and 2 outputs as batch ? lol

Drag use? If so, will it idle ok on 1 inj / cylinder? If yes - could you just have switchable power to the 2nd injector so you fire up, burn out and back-up on 1st injector then switch on 2nd in pre-stage / on the stutter box - similar to a fuel motor that closes off the fuel return? It will go rich but a raised idle speed should help at that point?
Just a thought?
