| - | You no longer need a GM MAF translator to run a GM MAF with a DSM ECU. We have included our own translation function inside the ECU itself. You simply select which GM MAF you have on your car, connect our optionally-available cable between the GM MAF and the car's MAF harness and you're set. Our cable also includes break out connections for the unused intake air temp and baro pressure inputs on the factory connector. You can use these to easily connect up your own sensors in their place. | + | You no longer need a GM MAF translator to run a GM MAF with a DSM ECU.

| **NOTE 1:** I absolutely must make mention of the fact that GM MAF outputs WILL vary from car to car. Most variations should be minor and easily corrected. However, it's not at ALL unusual to see a GM MAF installation require up to 30 or 40% adjustment from our base configuration! It's simply the way the GM MAF works. If you vary the size of the piping around the GM MAF, its output is going to vary accordingly. Our test platform used a 2.5" IC pipe with flared ends to 3" just before/after the GM MAF install point which was about 6 to 8 linear inches from the throttle body. If your setup varies from this, you can probably expect variations in GM MAF output from the base values we provide in ECMLink. There's a [[v3mafadjcombft|MAF adjustment]] function provided in the ECMLink application to help with this. | **NOTE 1:** I absolutely must make mention of the fact that GM MAF outputs WILL vary from car to car.

| - | In addition to having a multi-tab interface, the PC application has many other new features, some of which are mentioned here. Measurement units are selectable, so it's easy to switch between Imperial and Metric units, as well as absolute and gauge pressure, and lambda and air/fuel ratio. Each displayed item has an individually-adjustable display range, allowing the graph to be scaled to display the details of interest. Auto-scan, auto-connection and connection polling allows rapid connection to the ECU, making setup a simple task. | + | In addition to having a multi-tab interface, the PC application has many other new features, some of which are mentioned here.
