Hondata

before i rebuilt my engine, i used alpha-n setting to manage a set of itbs.

now, engine rebuilt with toda vtec killer cams, 12.2:1 compression ratio..etc...

if i upload a calibration based on stock map sensor, engine runs ok, but if i change to alpha-n setting,it starts or almost starts and suddenly the engine switches off.

any idea at hondata?

thanks

here are the kals.
