I have this setup in my car:
-Cams IPS K2.
-dual valve spring Crower and titanium retainers
-chain tensioner Toda Racing
-TWM ITB 52mm setup
-Toda Racing header and Supersprint catback
-Hondata K Pro with PRB ECU
-headgasket Hondata
Engine K20A2
The car is idles good, but the power on the dyno shows 160hp, but before TWM I had about 240hp.
Throttle response is not good at idle and engine rev up not really fast. It seems like ECU is retarding the ignition by 10-12 degrees, but we cannot find where and why?

Well may be, the MAP sensor is placed like here:Razathorn wrote:Sounds like your alpha-n settings are wrong and it thinks the engine is far more loaded than it is perhaps? What base map did you use? Does this itb setup have a vacuum manifold on one cylinder?
and has not got any vacuum manifold, but it reads fine (some mods has been taken), also I have used MAP based calibration, but nothing changes.
As a start calibration I've tried all Hondata's ITB's calibration and my own which I used with the RBC manifold - nothing happens.
I have datalog with AF ratio @ 13.5:1 - no bid difference though. about the ignition - this comes with hondata calibration for ITBsrensoyka wrote:You seem to be running very rich above 6500 rpm, is that by design? I noticed that all of your high speed ignition tables are identical, is that also by design?
