Reset ECU = idle problems

[jaktheripper]

Yesterday I unhooked my battery to reset my ECU, then when I drove it last night, everytime I pushed in the clutch or put it in neutral the RPMs dropped really low, then would raise a little but still be low (the tach looked like about 450 RPMs, but the SAFC was saying 580). Anyone else have this problem?

Give it time to idle relearn. Upon disconnecting and reconnecting, you can notice irregular idle and even sometimes the car will die when immediately driven. Idle RPMs can even dip to the low 200s.

It's normal.

Thanks for the info man. I was just scared because last time I reset it this didn't happen, I guess it's just sporadic though. Thanks again.

The reasoning for this is the ECU has to kind of "relearn" certian things and adjust to your driving and such. Its also a good idea to reset your ecu after driving long distances. Gives you a slightly more aggressive tuning as per say apparently. As long as your drive it hard after you reset it.
