I have a 2006 RSX Type S, as we may know in order to install the KProV4 we need the RSX-S 02-04 ECU and the O2 wideband sensor since the 05-06 ECU and O2 sensor are not compatible with the KproV4.
Which of the base Kpro calibrations should I start with since the 05-06 RSX-S comes with the K20Z1 engine instead of the K20A2?
From what I understand, the K20Z1 and K20A2 are not much different mechanically. I don't think it will matter much. Besides the ECU and 02 sensor, will you need to swap engine harness or other sensors as well? If not, I wouldn't be too worried about using either calibration. It may be something to ask Hondata directly if you are still unsure.
