8 injectors on m400?

[heds]

Hi, I know the M400 only has 4 injector drivers but is there anyway at all to run 8?
I have 4 large injectors installed but id like to add another 4 smaller injectors as primary.

Any input would be greatly appreciated.

Cheers

I would guess you could do batch fire with staged primaries and secondaries using only 4 outputs.

2 for the primaries and 2 for the secondaries, 2inj per output

i used 8 primaries on 4 outputs with a m400. 8X1600 sequential 4 cylinder. never did try to stage them in though, i guess you could with a simple relay.
