[QUOTE="Magnetoman, post: 109335, member: 2806"] Tormented for over a month by knowing Cyborg had a newer model AFR sensor than me, I had no choice but to address that unacceptable situation. So, in the spirit of nothing exceeds like excess, I upgraded my perfectly fine AFR system to the next level. In addition to having the latest Bosch wide-band sensor, I'm now instrumented to log, for up to 566 [I]hours[/I] (vs. 44 [I]minutes[/I]) continuously if so inclined, the AFR, throttle position, rpm, acceleration, and exhaust gas temperature. I have one unused position on the data logger so could add road speed with another sensor, but that [I]would[/I] be excessive. Or, would it? Hmm... Oh, and I have a separate, Canadian-made, aftermarket knock sensor controller I'll be testing to see if it provides useful information. It turns out the head-steady lug on a Gold Star couldn't be a more perfect location for mounting the sensor even had it been specifically designed for that purpose. This weekend I installed the new "instrumentation package" on my Gold Star Catalina, whose Monobloc I already had jetted to be [I]perfect[/I] using the old school method of "feel." However, in addition to testing the new instrumentation, this week should see the jetting get even perfecter. Unfortunately, no instrumentation upgrade comes without collateral damage. Now I'll have to spend time learning how to export the 566-hours of data to Excel as well as write a program to plot AFR vs. throttle position rather than slowly extract this information manually. I already know from my previous measurements that the AFR at a given throttle position depends on whether the bike is accelerating under load, at a steady speed, or decelerating on a downhill stretch, so I'll want my Excel program to incorporate data from the accelerometer. A scatter plot of AFR vs. throttle position is [i]exactly[/i] what is needed to understand the jetting over the full range of operation. See what you've forced me to do, Cyborg! The weather looks like it will cooperate for a few jetting runs this week by dropping to the low 100s. Unless something gets in the way I should be able to make my first runs on Wednesday when the high will be only 101 oF. [/QUOTE]
