The problem with mapping the K20 is most tuners aren't familiar with the analogue adjustability of the cams, with closed loop control.

The honda requires many more maps than a static cam engine. For example the fuel tables consider load index, revs, cam angle, and high / low cam, in addition to the usual coolant temp, intake air temp, tps......

They are reputably difficult to map without experience, and from what I've read, many of the standalone ECU options can't exploit all the features of the engine.

By the way, you don't need to remap to get a stock K20A2 through an emissions test if running Hondata -the stock map is a very close approximation to a UK OEM Honda ECU calibration, and runs a stock engine absolutely fine. A few of us have put our cars through the test using the basemaps.
