Sudden surging after downshifting
I hope I can get some help on this.
2014 Suzuki V Strom 1000 DL, ECU update and in Traction Control setting 1 (TC1)
I've noticed on downshifting my bike say, 5th down through the gears to either 2nd or first, combined with braking, that I sometimes get a bad surge of power, almost like the throttle is goosed. It's noticeable and concerning on a 90 degree turn, which is where I experience it. In a straight line, like stopping at a light, no problem. It's on a 90 degree turn, slowing down from 55+ mph with braking, downshifting, getting down to a safe speed (say 15-22 mph), and setting up for the turn that this brief surge kicks in. It throws me back in the seat.
I'd almost think it's software . . or I'm doing something that confuses it, or the ABS is interacting with traction control . . . local roads are clear, dry, hard pavement. And it's in the turn too. This would not be a good track day bike (I realize that track days are not its main purpose anyway, but you'd feel it acting up in those circumstances.)
Is it me (bad braking/downshifting technique), software, I'm in wrong traction setting . . . I will say, I don't probably always use both rear and front brakes prior to a 90 deg turn . . . mostly rear. Would that do it? I gotta get a handle on this issue.
