hi guys!
i have ep3 with k20a2 engine
ECU is PRA
specs:
- injen cai
- toda header
- supersprint exhaust

i find calibration in kmanager archive for rsx (k20a2, PRB) with same specs and rewrote all maps manually

everything works, dyno says about 225hp

but there are two problems:
- i got knocks on 4-5 rev
- i loose on hi-revs

maybe AF is too lean, cause i got it from PRB calibration?
trying to overall fuel on 7%

anyone can help me?

Those cam angles are crazy man. LOL. 40* @ 2200 at WOT? 30* at low cam Xover and 50* at high cam? The gear cant move that fast...You can see in the datalog the gear trying to catch up...

You need to buy a Wideband sensor such as PLX devices or Innovate LC-1 and wire it to your ECU pin E15. Then set Wideband input in KManager (Options > Settings > Wideband Input). Then you will be able to fully tune your car.

Also as Keto06 mentioned, you have to choose cam angles carefully. How to do that is best to see Hondata KManager training DVD or at least watch the videos on Hondata website and read the documentation.
