I have a Euro Civiс Type R with PRA ECU with K Pro.
Mods: CAI, RBC manifold, IPS K10 cams, 4-1 header, catback.
What calibration should I use to tune it?

you can use calibration from rsx s
K20A2 with K2 cams, header, exhaust, CAI

but if you have good tuner, you can start tuning from stock calibration....

You cannot use the RSX calibration with the PRA calibration. THe car will not run well. Use the standard dyno tuned calibration and tune the car as soon as possible.

So we have two diffirent opinions here. Who knows for sure? :)
Can I use the RSX calibration or not?
Did someone already done this on PRA ECU with this mods?

I used over 5 differents calibration from RSX, and run very nice...
(dyno power testing, not road testing)

ofcourse needs tuning...

so if you are tuning very well,
it is doesn`t matter with which calibration you are starts, stock Euro CTR or RSX ..

starts from euro ctr ctock is little safely, becouse some rsx maps has aggresive ignition...

The RSX calibration have different ECU settings. THe PRB ECU itself needs a wideband to work. THe PRA uses a narrowband. I would never mix PRB calibration with PRA ECU. It could work but I think it is more decent to start with a PRA calibration. I guess you could copy-paste some maps from teh RSX calibration though.

Has anyone of you tuned CTR with IPS K2 camshafts?

I've tuned two PRA's with Toda N2 cams. Started with a calibration I have made for i/h/e K20's (actually an improved dyno tuned calibration). I might be tuning a Euro CTR with IPS cams in the next month. I would stay below 45 cam advance so keep this in mind.
