Thanks for any help/insight :) I (and lots of other GN owners) have successfully used the batch fire DFI box with P&H injectors. I always thought it was designed for them, though admittedly I never took it apart or called Accel about it. No problems thus far. If you want to mod it cheap, you could do like I do with the stock GN ECMs; take the drivers in the DFI box; replace them with the CS452/3s, and put the extra bias resistor/zener on perf board inside the case. If they're TO-220 cased transistors, you can put the Cherry drivers in their place and bend the extra pin up to connect 'em.
