One is a 0-1v narrowband simulation and another is a 0-5v wideband output used for datalogging more precise A/F ratio data. You would typically run the narrowband output to the ECU's front O2 input so the ECU could run normal closed loop off this signal and then run the 0-5v output into a different ECU input for datalogging purposes. text/html 2010-03-11T15:38:01-05:00 dmertz http://www.ecmtuning.com/wiki/aemwb?rev=1268339881&do=diff A number of people have various problems with the AEMWB display routine. There are a number of reasons for this, but most seem to revolve about the AEM's weak analog driver circuitry. It's simply unable to properly drive a number of ECU inputs. text/html 2010-03-10T09:54:48-05:00 twdorris http://www.ecmtuning.com/wiki/announce?rev=1268232888&do=diff We're constantly working to improve our products and roll in various requests from our users. This page will contain some updates on what we're spending our time on. Release date I know the first question coming is “when”. As soon as we know, we'll post it. I promise. I'd rather wait until we are sure about a release date than to keep posting made-up dates and missing them. The very minute we feel comfortable enough with a release candidate to schedule a date, we'll post it up. text/html 2010-03-08T07:33:36-05:00 twdorris http://www.ecmtuning.com/wiki/sdveadjsdratio?rev=1268051616&do=diff This page describes an adjustment tool in the ECMLink application that helps to dial in your speed density (SD) VE table based on data collected from a mass airflow sensor. If you do not plan to run speed density mode with your car or you do plan to run SD but do not have a mass airflow sensor installed for dial-in, then this page is completely useless to you and you should ignore it. text/html 2010-03-02T05:47:03-05:00 twdorris http://www.ecmtuning.com/wiki/externalsensorinput?rev=1267526823&do=diff Note that the following lists out all the available inputs on the 1G and 2G DSM ECUs. Most of these have special cases associated with them to be useful as a general purpose analog input. The most freely available inputs are the EGRTemp input on a 1G ECU and the RearO2 and MDP inputs on the 2G ECU. The rest have special cases to consider with them. Some may even require a buffer circuit to be driven properly, depending on which sensors is connected to which input. text/html 2010-02-27T06:45:01-05:00 twdorris http://www.ecmtuning.com/wiki/linearitems?rev=1267271101&do=diff Using pre-defined sensors In order to datalog an aftermarket sensor in the ECMLink application, you must first tell the application where to find the sensor (which ECU input pin it's connected to). You do that in the “Pin Assignments for Datalogging (PC-side)” section of the ECU Inputs tab shown to the right (click to enlarge). text/html 2010-02-27T06:41:13-05:00 twdorris http://www.ecmtuning.com/wiki/externalsensorlist?rev=1267270873&do=diff The lists below detail which sensors the ECMLink application supports for datalogging. Others can be added fairly easily, but honestly doesn't happen all that often. The V3 application allows for user-defined sensors. The full process for defining 100% custom sensor display modules is not documented yet. But the process for logging custom linear sensors is documented on the linear items page. This lets you log or tweak the logging of any linear wideband kit, boost or fuel pressure sensor. text/html 2010-02-26T13:13:16-05:00 twdorris http://www.ecmtuning.com/wiki/fuelsettingshelp?rev=1267207996&do=diff This page describes the basic usage of the Fuel tab in the ECU Config section of the ECMLink application. This page is just a dump and reformat of the same information provided in the help file with the ECMLink application. Fuel Adjustments Table The Fuel Adjustments Table allows rpm-based adjustment of the air fuel ratio relative to the ECU's stock operation.  Moving a point up (or increasing the adjustment value by typing in the numeric table) makes the mixture richer; lowering it makes… text/html 2010-02-26T13:12:07-05:00 twdorris http://www.ecmtuning.com/wiki/engineandecu101?rev=1267207927&do=diff It's simply impossible to give a full account of engine operation and ECU tuning concepts in a couple paragraphs. So please don't take the following as a complete summary of everything involved. It's not. This section is simply intended to orient the reader's mindset in the right direction with some high level concepts. text/html 2010-02-26T13:11:16-05:00 twdorris http://www.ecmtuning.com/wiki/baseinjectordata?rev=1267207876&do=diff These values were gathered from various sources. These may not match exactly with the values you've seen elsewhere, but they should be fairly close. The problem is that each injector can behave a little differently from another of the same size and manufacturer. So there's some variation that simply can't be accounted for in all cases. Start with the values listed below and fine tune from there. text/html 2010-02-25T08:28:55-05:00 twdorris http://www.ecmtuning.com/wiki/prodcompare?rev=1267104535&do=diff By popular demand, we have released V3Lite for the 1G and 2G DSM platforms in addition to our regular V3 package. This page summarizes the differences between these two products. UPGRADE NOTE: Keep in mind that the V3Lite package is upgradeable to a regular V3 package at any time. You simply purchase a V3Lite conversion off our website and download a new firmware file for your ECU.
