ECMLink 101 - Sanity checks
On this page, we're going to assume you've already run through the install procedure and have gotten a good connection established with the ECU. If you have not, please review the Installation page first.
Verify
Pull up the ECU Config tab and verify some basic settings. You should see something like this.
Base MAF type
In the MAF Comp tab, check your Base MAF type. This should say something like “Stock”, “3G/EVO8”, “GM 3in”, etc. You want to make sure this matches what you actually have installed on the car. If you have a GM MAF translator, then you'll want to select “Stock” because the translator is supposed to provide a signal to the ECU that more or less simulates a stock Mitsubishi airflow sensor.
Global fuel
Go to the Fuel tab and check the global fuel adjustment slider. This one is a bit more complicated to explain simply because there are a lot of things you can do to your car's setup that will affect this value. These thing include:
- Changing injector size (of course)
- Changing base fuel pressure
- Changing fuel type (gasoline, E85, etc.)
To help with this, there is a “calculate” button on the Fuel tab near the Global fuel adjustment area. Click this Calculate button and enter appropriate values for your specific setup. The following screenshot shows a “typical” FIC 850 configuration on gasoline with a 2G ECU.
1G ECU will default to a different base fuel value (37psi). Adjust this only if you've installed an aftermarket fuel pressure regulator or you know your car is running some different pressure than the default.
There are a number of pages available to provide more help in this area.
You're basically on this tab just to convince yourself that the global fuel adjustment value is appropriate for your configuration. This is VERY important. Do not gloss over this. The deadtime value isn't nearly as critical until you start trying to fine tune your fuel trims.
