Do you have your calibration loaded in the software when you are tryging to make these changes?

Do you have your calibration loaded in the software when you are tryging to make these changes?

The thing is I am not sure if I am doing it correct. Can you give me a brief run down. By the way I rewired the sensor to kpro directly to analog 0 instead of the eld.

Ok so i figured out my issue just dont know how to fix it,im running a base a03 but if i load a cal for the a3 it does not allow me to change the selection, but if i load a type s cal it allows me to change the selection to external 02, dont know whats up with that.

You can only use the wideband that way on a PRA or PRB calibration.

From The help file: External wideband - uses an external wideband (connected to the KPro analog input) for closed loop operation. Used for PRA calibrations wishing to run from a wideband or PRB calibrations without a factory oxygen sensor.

Can I copy table values from the base cal an use it in the prb cal

[Spunkster]

Fuel values are different, but ignition values can be copied directly as long as the indexing is the same.

No sense in creating another thread.... I'm having this exact issue.

'05 EM2 w/ '02 rsx-s motor & ecu, using o2 sensors from DC5 cat with EM2 o2 plugs.. only have base 550 map, still not "tuned"..

I've already swapped locations of O2 sensors(up & down)...
I've already ck'd fuses...
Replaced both o2 with new Denso(motor had 80k, so needed to be done)
Not quit sure of which vehicle P1166 troubleshooting guide to begin with.

Again, apprec the assistance.

Try the ECU in a known working vehicle.
