I disconnected the TPS tonight, went for my usual 20 mile test ride, & that made a minor improvement in decel popping.
The real benefit though was a more stable AFR on acceleration. The bike starts and idles well, too. Cruise AFR is just as stable as before, if not more so. The bike seems to pull harder at lower RPMs, also.
So far, no downside to running the full advance, full time. I might even get a block-off plate for the TPS, as I like the disconnect so well that I doubt I'll use the TPS again. So far, disconnecting the TPS is all good.
