are you able to adjust the rev limiter and vtec crossover by using a labtop or is using the button the only way? i cant seem to set my vtec or my rev limiter correctly and cant figure out the problem. i do exactly as the video and manual say but its not working. any help would be appreciated. thanks

 

it depends on what ecu you are using. obd-1 and later ecus can set the rev limits on romeditor but i havent' figured out how to do it with obd-0 ecus yet. maybe in the next edition of rom editor. maybe try switching the position of the plugs at the hondata blue box. there is another post floating around where the box was labeled wrong. the clutch and set buttons were labeled backwards.

 

im using a p28 obd 1 ecu in my 90 hatchback
