I think I can handle that.
Interesting... we'll see what B3703 does.
Going to play with the calculators when some decent weather breaks. My cam has a good amount of overlap, so I guess I should see a change.
Got some data yesterday, but I goofed and logged LTFTs with and without cam sensor, didn't change the value at all. Will re-engage tomorrow and add STFTs as I ASSume you were after those as well. Fair warning, after yesterday's logs truck isn't looking so hot. Left side ran lean and stayed that way, right side didn't alternate enough so take it for what it's worth.
Yeah, we will need STFTs as well. If it does change anything, the change might be small and only show up on STFTs.
If the left side is significantly lean, you should probably investigate that before worrying about this experiment.
Wideband lives in the left bank and showed 15-16:1, truck got weird after I corrected CMPRET and did a CASE relearn. It's been getting quirky lately, there's definitely a mechanical issue waiting to be discovered. I really didn't expect the effect to be so significant, the root cause is buried deeper than just a bad O2.
By utilizing the 2 external inputs of my V1, or with the converted EGR and A/C inputs. Could monitor camshaft, crankshaft sensors as well #1 spark and #1 injector. Does the scanner support enough resolution to get something useful? What is the sampling rate? Kind of like picoscope output.
When opening a stock 97C5 tune file in hptuners the boundry value is shown and quite different from later values.
7.22 boundry and 4.78 normal(B3702)

Scantool logs pids at 10Hz for LS1A/LS1B/P01 and 40 Hz for E38/E67.
1997/8 LS1's do have various differences compared to later LS1's.
