Will a Injector driver box help drivability on 1600cc inectors?
I will be running FIC 1600cc injectors on E-85. I was trying to find a solution to help with drivability other than going dual injector setup or the ID2000's.
Will a injector driver like AEM or FJO help?
Anyone running them?

The driveability problems are due to the injector, there is no fix for it. The driver will help consistency for sure, but you still have the same problems with very non linear fuel flow. This graph explains it pretty clearly.
The red line is the 1600cc injector. If you look at your datalogs, you'll see that idle and light load stuff is all between 1-2msec, right in the middle of the non linear flow.

The old Bosch is a pintle type, and I believe is what Deatschworks and such sells. If what the OP has is not a Bluemax (and purchased recently), that is what he has. It served as the staple 1600cc injector, and suffered from poor part throttle performance (probably due to the reason depicted in the graph above). I advise avoiding this injector completely, especially where E85 is used (they are prone to fouling).
The Bluemax injectors are an entirely new, ball type unit, and are incomparable to the old Bosch injector (which should be given a permanent burial).

Try to avoid the Bosch 1600 cc injectors. They were not intended to use with fuel.
I got some really strange afr readings below 2.0 ms and the graph from Tony1 explains why.(tried with and without driverbox)
Save yourself alot of hassle and stay away from Bosch 1600 cc. Try the new ID2000.
I have ordered a set myself.
I am currently running Bluemax 1450 cc which are good, but seems like I need alittle bit bigger injectors, so I will try the ID2000.

I don't care what ecu you're running the 1600's with, Haltech, Motec, whatever. It's not going to be right. The ecu can't fix the pintle bounce on the injector that causes the disruption in flow between 1-2msec.
Mike, I know you love and sell Haltech, but it's not a miracle computer. The idle quality may seem 'perfect' to you, but it's far from it, it can be much better with a better injector. On that topic though, does the Haltech not have peak and hold drivers built in? You really have to run an AEM injector driver on top of it?
It's not that there are 'issues' with the 1600's, it's just that you're not going to get a predictable and consistent a/f ratio between 1-2msec pulsewidth. Even on E85, you're going to idle and cruise at light throttle in that PW range. The graph clearly shows what happens there, no computer can change that.
