Ok, cant sleep for thinkin about this.
Ive got two 2d systems, one pre turbo and one at the manifold (which looks like its not needed).
One is wired into cylinder 2 and the other cylinder 3 injection pulse.
I propose that i place both jets together before the turbo but another 12 or so inches further back. Use matching jet sizes for each (i.e two 0.5's or two 0.6's), they will inject alernately giving a move even flow into the inlet charge and give a finer spray, both desirable.
Finally move the ecu inlet pressure combined temp sensor to just before the throttle to allow maximum temperature reduction to be recognised by the ecu.
Added advantage if one pump failed or had a blocked jet, the other would still be injecting reducing the chance of sudden detonation.
Did i mention that my ecu uses independant cylinder knock detection
And maybe, like Bill Shurvinton said, remove the IC altogether...........
