Resetting Base Idle with WDS

XJ-S
1

I have the 1996 XJS with the AJ16 engine.

I have been able to piece back together a fully functioning WDS. It lets me reorient oxygen sensors and reset the TPS, however when I ask it to reset the base idle adaptations, it wants me to input some CO readings, in either ppm or %.

I came across a product called “Gunson’s Gastester”. This device is made to measure CO readings from a tailpipe, for the home enthusiast! Reading up about it, it isn’t terribly accurate, but maybe close enough?

I then thought, what if I just take the car down to my indie garage and have them run an emissions test on the car and use those readings? That would be perfect, and they should only charge me the going rate for a state inspection!

Does anybody have any other ideas or suggestions? It would be pretty amazing if I were able to pull this off with the WDS.

just curious , is not resetting the tps same thing as resetting idle adaptations ?

They are both distinctly separate options in the WDS. They are under the same sun-menus, so they absolutely cannot have the same function.

I’ve successfully used the Reset TPS option. The base idle required CO readings.
