'09 Inconsistent Engine Braking: Bad TPS? Bad Bazzaz Parts? Other?
Hello, I have a bit of an odd issue
Occasionally when I roll off to 0% throttle, it seems like the injectors aren't turning off and I have almost no engine braking. Turning my bike off and back on fixes it until it happens again, which seems to happen more during aggressive riding (though it's happened a few times on the freeway) or when it's warm out. FI light never turns on, and the bike only has 14k miles.
Unfortunately I'm awful at keeping records so I can't remember when it started, and I've added a Z-Bomb, Z-Fi, and Z-AFM in that order separately. I've asked Bazzaz and they say they've never heard of that happening.
It really makes me unable to fully trust my bike, at least to ride aggressively as I heavily rely on engine braking.
Is there any order or specific method I should troubleshoot? It's extremely inconsistent to test for as is. Could it be the TPS or is it more likely one of the additions? I have recalibrated the throttle in the ZFi.
TL;DR sometimes it feels like real world 0% throttle isn't being registered as 0% by the ECU, and it's fixed by turning the bike off and on
