Next, let’s take a look at the “RPM Offset vs TPS” table. This table is used to provide better drive ability in stop and go traffic. What this table does is raise your idle by the set RPM depending on how much you press your throttle. So basically, once you attempt to move your car from a stop the idle will be bumped up to a higher number so that you have more engine speed and not stall your car. Some vehicles just leave this all at 0 and have no problem getting the car to move, but for ease of driving you can set your table to something like the picture below. Just make sure that your slope does not start going until your throttle value is above your idle value. In other words, if your TPS resting position is 2.3% make sure your upward slope starts after 2.3%.
