Right, but your not completely deleting the ECU's memory unless you pull its power supply. Pull it, let it sit for a couple of hours and then put it back on. Make sure your car (assume it is an auto) is in Perf mode, and then rev out every gear when you accelerate a couple of times. And it will then learn to go to redline on your gears on full acceleration runs, and give you your best acceleration times. good luck, Nick B Visit SPOC National at http://www.spocnational.org
