I am looking for a free tunning program for my b16. have used several different progams for example hondata, chrome, and uberdata. all but one chip i wrote was pretty much bad and the one i'm running with still isn't great. the one i wrote with uberdata when i would hit 8000 rpm my cel would come on and it would go into limp home mode and the 2nd time i did it, it went to 7000 my cel came on and it went into LHM any ideas or possibly better stock jdm b16 programs i can down load and use?? I'm running a p28

 

did you tune on a dyno or wideband? all the freeware that you listed are pretty much considered leading edge, since its being developed all the time.
