| **__RUNNING WITHOUT AN IAT SENSOR__:** You can run speed density reasonably well without an IAT sensor at all if you have to. It is absolutely better to have one, no question about it. But if you find yourself in the situation where you simply can't get an IAT sensor installed but you need to enable speed density operation anyway, go ahead. Just make SURE you go into the Direct Access tab and zero out the **SDTempWeighting** table. Doing so basically tells the ECU to ignore the IAT input when running SD. | **__RUNNING WITHOUT AN IAT SENSOR__:** You can run speed density reasonably well without an IAT sensor at all if you have to.

| You wire up a pressure sensor much like you wire up any other aftermarket sensor for logging. The details of which can get complicated because there are several different inputs you can use and several different sensors. So it's hard to write up a COMPLETE how-to on this. | You wire up a pressure sensor much like you wire up any other aftermarket sensor for logging.

| If you have our GM MAF cable already, GREAT! You can use the breakout points provided on that cable to connect your MAP sensor and IAT sensor directly to the car's wiring harness. Our [[gmmafiatbaro|GM MAF IAT/Baro page]] describes how to do this. | If you have our GM MAF cable already, GREAT!

| Because you can connect your MAP sensor to any number of ECU inputs, you have to tell the ECU where it can find this sensor in order to use it for SD operation. You do this on the ECU Inputs tab in the "Pin Assignments for ECMLink Functions (ECU-side)" area. | Because you can connect your MAP sensor to any number of ECU inputs, you have to tell the ECU where it can find this sensor in order to use it for SD operation.

| Tell the ECU to ignore incoming MAF data and calculate it from speed density data instead. You do that on the MAFComp tab by selecting "Speed Density" as your Base MAF type. | Tell the ECU to ignore incoming MAF data and calculate it from speed density data instead.

| - | **NOTE:** If you have a REALLY old version of V3Lite, then you'll find a checkbox on the SD tab labeled "enable speed density" instead. If that's the case, pleas consider [[v3firmwarehowto|upgrading your firmware]] because your V3Lite ECU is seriously outdated. | + | **NOTE:** If you have a REALLY old version of V3Lite, then you'll find a checkbox on the SD tab labeled "enable speed density" instead.
