Let’s start with the stock set up and go from there...... With the stock tee all the air was pulled from one meter and so the Idle circuit being on one side was not a issue as it read "all the air coming in". The reason the JWT kit had to have a low speed kit was because it was only looking at one side. Because the idle circuit stock is only on one side, this causes all or most of all the air to be pulled from the one side the meter is on at idle. Reading almost all the air at idle makes a rich condition and causes the need to split the idle air circuit with a low speed hose or a tee in the idle circuit to basically finish splitting the air system. The biggest issue is as you open the throttle a little, the air is still being pulled through the idle circuit and changes are occurring that are less than ideal when looking at only one side causing the need for some voodoo tuning to get it to work. It was a quick and dirty fix that never was perfect, but it did get the job done when nothing else was available. The Selin translator removes the stock tee and connects a sensor to each side; this allows all the air to be metered JUST LIKE STOCK DOES. Think about it................. The ECU can only read one signal.....So the translator reads both meters that are reading 100% of the air and it sends one signal back to the ECU just like one meter did stock. Are you getting it yet? When the Selin translator when selected is add, it simply adds both signals and translates back to the ECU the total air being pulled in and we get the exact same reading as one meter and the exact same chip works exactly the same. Here is the bonus part...... When you select average and the Selin translator reads all the air coming into both meters and after adding them together, it sends exactly half that reading back to the ECU so that a dual pop chip can be used and now the ECU can support double the stock horsepower. It does not matter if one side pulls more or what the idle circuit does, because it measures "all the air" and depending on the switch position gives 100% reading to the ECU or a 50% reading to the ECU.
