[QUOTE="mrose75, post: 14481701, member: 7655"] I'm remote tuning to get my new 2.3 Whipple dialed in. I ordered a 9-pin mini din cable for my XCal2 and it came in today. Cut the cable in two, broke out the multimeter and Analog 1 was blue and Ground was red. Hooked up Analog 1 to the gray wire from my AEM UEGO sensor and ran the ground to a ground. I used the equation (v*2)+9.75 and started logging. During my pulls the A/F gauge read consistent, as in around 11 and dipped into upper 10's near redline. But when I look at the logs, Analog 1 was all over the place. Bouncing back and forth between 9.xx and 19.xx. At no time did it jump around like that on the gauge. I even checked on the excel version of the logs and it was the same way. All over the place. But when I look at the average it sat at around 11.3. It seems I'm doing something wrong. I would expect the Datalog to more consistently match the gauge reading. [/QUOTE]
