Ok, someone please excuse my lack of knowledge with this stuff....
Between 25 to 35 % TPS, I get up 4 to 6 deg KR.
RPM is from about 1700 to 1900.
I can make it do this anytime.
I saw this using my VCM scanner. I tried to save the file, but the scanner froze!
For the fun of it, here is a screen shot of the scanner, as I idled in my driveway.
Thanks
