Car: 2010 CTS-V
Stock blower, stock injectors
Using HP Tuners Pro with the inputs on the left side
Hooked up an Innovate LM2 - followed the directions on configuring the analog output in the innovate software
Innovate being powered by cigarette lighter power adapter
O2 sensor in tail pipe using innovate exhaust clamp
wired and Configured the analog input #1 correctly in hp tuners. min 7.35 max 22.39, denominator 0.332, 7.35 on the right side
Inserted into vcm scanner chart
Displayed on chart view in vcm scanner.
Now here is the problem.
When i start a scan, the wideband analog input signal is extremely noisy. It flips from 10 to 19 several times per second and is unusable. I tried running an additional ground from the battery negative terminal twisted together with the signal ground from the innovate into the hp tuners. That didnt help.
Is this something that has been seen before on this forum?
i searched and saw almost the same question here:
