verify with Protune the occilation of the voltage of the lambda probes (0.5 V to 1.1 V approximately)
to make a reset of the ECU adapter map
I cleared the adaptive maps and the fault history. Lambda readings, front & back, were in the neighborhood of 0.73 V and very reactive. Looking good. Thanks so much to you, GLLOQ and Rog G. User forums like this are fantastic resources.
I put everything back on and went for a brief spin. I f*g love this crazy car.
