yea u can do it manually, drive your car around till it warms, like 15 mins, then turn off. find the fusebox under the hood and it should have a diagram of wer the ECU is. Take out the ECU for about 10 minutes and make sure u have the windows up, car, radio, and air turned off. after about 10 mins, put the chip back in and turn the car on and let it run for another 10 mins, do not push the gas pedals or anything else! then turn the car offthen back on and take it for a spin.if you did it rite then all the info will be erased and it will have to start again, so drive aggresively, like redlining and w/e so it can get some info. sounds to easy rite?
