Many are used for critical engine operation, but some are available for datalogging aftermarket sensors. The problem is that some of these inputs are incompatible with some aftermarket sensors. In particular, the 1G EGR temperature input and the 2G baro input have pull up/pull down resistor configurations that some sensors are not capable of driving properly. text/html 2025-10-19T07:50:39-04:00 twdorris http://ecmtuning.com/wiki/sdsetup?rev=1760874639&do=diff ECMLink - Speed Density Setup This page describes the basic process for getting your car setup for speed density operation with ECMLink. If you need a more general speed density tutorial, then the Speed Density 101 page may be what you're looking for. In fact, we're going to assume you already know everything off that page as we discuss items below. So it might be a good idea to read over it even if you're already pretty familiar with SD in general. text/html 2025-10-18T02:47:04-04:00 twdorris http://ecmtuning.com/wiki/ethadapter1g?rev=1760770024&do=diff Ethanol Sensor to 1G SD Cable Adapter MAF connector wires The adapter we provide to connect an ethanol sensor directly to our SD cable has two free pins that need to be installed into the MAF connector end of the SD cable. For a 1G-style MAF connector, you must first remove the orange locking tab. This is done by simply prying on the small hole in the locking tab using the connector housing as your leverage point. Then you simply push the pins (and seals) into place and reinstall the locking t… text/html 2024-03-15T10:57:55-04:00 twdorris http://ecmtuning.com/wiki/connectionproblem?rev=1710514675&do=diff Connection Diagnostics Port currently owned First, verify that you have the correct COM port selected in the Edit->Options menu as described below in the “Which COM port” section.

This is not practical for a laptop used by a shop or general tuner when connecting cables from multiple customer cars. text/html 2023-07-04T17:12:33-04:00 twdorris http://ecmtuning.com/wiki/v3litefirmwarechangelog?rev=1688505153&do=diff ECMLink (V3Lite) Firmware Changelog Firmware upgrade page This page is ONLY for the V3Lite package.
