- serial number of your K-Pro: 4991
- KManager version: 1.5.1.0
- what sort of vehicle you have: Civic Coupe -95
- what sort of ECU you are using: PRA
- anything about the car which has been modified from stock which may affect the ECU: A custom engine harness.

Is it possible to load a PRB calibration to a PRA ECU?
I am using a wideband lambda, but in the datalog the A/F is 14,7 all the time, but the short trim is running up and down.
I just want to see the correct A/F value. I am running in closed loop.

A PRA cannot use a factory wideband. If you use a aftermarket wideband it must be able to output a narrowband signal to the stock O2 input as well if you want to run closed loop off of one sensor. You must wire the wideband output from the wideband controller to the ELD input on the ECU.
