It takes a lot longer than 30 minutes to reset the ECU... Try a few hours... Maybe longer. Though, I must say, resetting the ECU so that it could "learn" how you want the car to perform is somewhat of a fallacy. The ECU constantly "learns" for lack of a better term. Think about it... What are all those sensors (MAF, o2, etc.) for? You shouldn't need to reset the ECU after doing mods because the ECU adapts to the new mod anyway.

Hmm... That's interesting... It shouldn't happen, and you shouldn't need to reset your ECU. Hmm, if you followed the timing advance procedure from SE-R.net, I recall seeing a typo. It said to rotate the distributor towards the firewall to retard, and towards the front of the car to advance. It should be the other way around: Towards the firewall to advance and towards the front of the car to retard. I ended up advancing the timing on 3 cars (and did a cam install on a 4th car) over the weekend, and everyone felt a noticeable SOTP gain in power from the moment they drove off.
