Guys please help.. i have a jdm f2b in my 93 delsol and here lately its been acting up. So i got the code 0, checked the thermostat ground and that was the problem. Solderd new ground, fixed. Then everything was smooth for about a week. Then no vtec. I got curious and seen if vtec was coming in when car is cold. And yes it is. Its on a h22a basemap. All stock didnt adjust anything. Other than the vtec checks. Only unchecked them to see of id have vtec. Once car warms up i have no vtec.. can anyone help me???
