Installing a 2009 k20z3 into my buddies 2002 ep3 si USA as an upgrade over his stock k20a3, and he has Kpro v4, but the tunes via flashpro for the 06-11 si are diff than the kpro rsx type S a2 and z1 tunes. Translating the flashpro factory z3 tune over to kpro doesn't look plug and play like I thought. Instead I was going to throw a rsx type s tune on it as a starting base and take it somewhere for tuning, but after reading about timing and such I'm weary. Even the a2 and z1 tunes are slightly diff on the type s than the z3. If anyone has a k20z3 tune from 2006-2011 and can post up the basemap or convert it over from flashpro to kpro so its plug and play that would help so much. Going to be using all the ep3 parts so no throttle by wire or anything like that to make it completely plug and play. I orig thought the rsx type s tune would run it, but it sounds like more of a project as far as the tuning goes. Hope someone has that k20z3 basemap, but already converted in kpro!!

Thanks for your time and any help!!

This will need to be tuned on the dyno for maximum gains and to be safe.

I understand that, but I just want the 06-11 si I tune thats in the flash pro app, but in kpro

That is not possible as they use completely different code and cannot be swapped from one to the other.

Start with an RSX Type S base calibration and adjust accordingly.
