Yes they are the same thing, one is in liquid form and other is paste. Get which you prefer to use. Liquid takes less time and effort slightly. I tried with a machine, used a Biloxxi for some time but the result by hand for any wax/polish is more satisfying for me than the machine. Machine only feels suitable to me if compound is needed.
About resetting the ECU, if a mechanical problem is there this solution might not help in my opinion. A mis-tuned engine, dirty throttle body or dirty fuel filter won't be cleaned by resetting ECU. So i think first the phenomenon of physical things needs to be catered for Sir Jee. To be honest i have never gotten such a resetting ECU thing done, that scares me like: what if it goes totally wrong.
