easiest way to reset ECu

Well like it says... Will disengaging the battery do the trick or do I need to do something else... Unplug ecu from car?

It's the 7.5a fuse. You only need to pull it for 30 seconds. Put it back in, start the car & let it idle until the fan comes on twice.

Or 10 minutes. If your radiator is too big for your engine

Re: easiest way to reset ECu (Spade)

if your car is surging in idle will your ecu reset properly?

Yes and no. It will be able to get rid of all of the old codes and then will generate new ones once the bad devices talk to the ECU.
