I wish to disable the power and acceleration enrichment mode and O2 sensor adjustments until I get the open loop map dialed in... If there are any other modes that may influence the base tune I need to disable, I would appreciate any forsight...
The 5K variable resistor I hooked on the ECT connector (an interesting troubleshooting device) in place of the ECT is not as good as I first thought....
next thought was to adjust Minimum MPH for PE set to 120 MPH?
Stabbing in the dark...
