so i just went ka-t a few days ago and everything worked fine.Today i started my car and it ran rough. I look inside the car and the check engine light is on and the light on the ecu is also on.I have a chipped ecu from a friend for t25 and 370cc and stock maf. so i restart the car and the lights are off and drives fine. So i took it for a drive and with in a minute the check engine came back on and the car started to run rough again.
When i pulled back into my driveway the light turned off and the car ran fine again.I checked the boards in the ecu to see if they were loose and they were fine. Today when i got home i started the car. In about 2 minutes the check engine came back on and the car starting running bad again.I turned the car off than back on and the light is off and the car is running fine.So im wondering if its my ecu or something with the car.
