Throttle Cutout
I just completed a LS swap and I opted to tune with HPTuner. To get the car in the ballpark I also ordered a base tune through PCMofNC. Long story short we took it out to make a few pulls to test the tune and it seems that the throttle completely cuts out mid pull randomly. The setup utilizes a drive by cable system so I know that the throttle blade isn't actually closing however the data recorded suggest that the TPS is at zero percent when this occurs. I have already replaced the TPS and MAF sensor. Has anyone had this issue or can anyone make a suggestion. I have attached data of the problem area in and excel worksheet as well as in the HPTuner form. On the HPTuner data-log the issue occurs from 600 frames to roughly 800 frames.
Side notes
- I am not letting out of the throttle
- VSS is not hooked up
- O2 Sensors are disconnects
