Getting bosch 1600's to idle

[mark4g63t]

Yeah, they're definitely harder to get fuel trims in line than compared to my last injectors (650's). E85 did help a lot as before on 92 octane my car wouldn't move more than a foot before it would die. After I put in the E85 I was able to drive around the block with only global and deadtime adjustments for the fuel change.
I don't have a problem tweaking things every now and then as I always drive with my computer (car has been more than unreliable lol)
What would you suggest I set timing to? I've heard that E85 requires a little more timing advance than pump gas does.
