I agree with Slashee, unless you for some reason absolutely have to use ABS you're probably better off with other materials. Even though I managed to get good prints with ABS most of the time, the hassle just isn't worth it. Apart from the fumes it also ate the TFM couplers in my printer with the high temps, and while I most of the time had good bed adhesion with glue stick I still never trusted it fully.
I use PLA for probably 90% of my projects. The only time I use something else is when I need flexible prints where I use PEBA-S or sometimes TPU, and prints that need to resist heat a bit better where I use PETG. As a last resort I'd probably try ASA, but I'm never going back to ABS unless I have to.

I don't think it can be done in Cura. A post-processing script could do it (although you'd spend AGES waiting for it to heat up and cool down at least twice a layer), but it sounds far more like a hardware issue. Unless the flow rate is different for the infill (can be changed in Quality > Infill Line Width, Infill > Infill Layer Thickness, Material > Infill Flow, Speed > Infill Speed and Speed > Enable Acceleration Control > Infill Acceleration, so make sure all those settings are the same as the walls) is different to the walls, it should print just as well.
I've printed ABS with a Bowden extruder and it went about as well as printing ABS goes in general (%#*@ing annoying). Your temperature seems pretty low though - I ran mine at about 255° (for the whole print).
You might want to try calibrating your E-steps, and I'd also make sure your plate is level and your Z offset is set correctly if it's having trouble only on certain parts of the print.
My favourite advice though? Don't bother with ABS unless you have a really, really good reason to. People say it's stronger than PLA, and it is, if you're mass producing parts using injection moulding, but for FDM printing about the tangible difference is that it's a bit less brittle than PLA. I don't think it's worth all the hassle - it barely adheres to itself, it warps if you so much as breathe in its direction while it's printing, and the fumes are poisonous.
