i have an all motor b18b w/ forged internals, head work and hondata.
I make 180whp and 140torque at 7000 rpm. my idle is all out of wack at a cold start, will go up to 3000rpm from start to warm. When the motor is warm it ussually doesnt go below 1500rpm. this just happened recently that it wont hold a good idle that the hondata had set. wtf, im living in newhapshire from newyork and this is a real headache. please tell me someone knows what is up. just bought a crx for a beater , taking my b18b civic off the road till i know whats up.

I need to check hondata connection to make sure that straight
