Firmware upgrade page
This page is ONLY for the full V3 package. If you have V3Lite, you need to refer to the V3Lite Firmware Changelog instead.
This release is a major revision change. Please note that you must be running at least v3.18.205 of the laptop application before you upgrade your firmware.
This release adds a number of major new features to the ECMLink device.
First and foremost is speed density support. SD operation is explained in a lot more detail on the following pages.
If you've wanted to run more than 4 injectors, here you go. You basically configure a set of conditions to trigger the mode and then configure how fuel should be adjusted when the mode is active. You can even dial in a delay between when the mode is technically triggered and when the adjustments actually go active. This can help with installations that use a mechanical relay, for example, to activate the secondary injector bank inputs to their injector driver box.
Want to see what this roughly looks like? Screenshots are provided below.
Yes, we're finally adding the concept of switchable maps. These are complete copies of your fuel and timing maps that you can switch between at any time. You can either have these switched on automatically based on a set of criteria you define (for example, to switch in a set of aux maps when nitrous activates) or you can define an input into the ECU to have active control over the switching function yourself with an external switch of some sort.
A screenshot is actually part of the AuxMaps shot posted above.
Having control over the fuel pressure solenoid output has been used for several years to do all sorts of things, even some we never envisioned. But the need exists for additional control, so we're adding the same type of functionality to the EGR output as well. You can use this output for all the same stuff you could with the FPS output. You can control your cyclone manifold, for example, or your BOV bottom-port pressure or activate nitrous or water injection, etc., etc.
We have entirely redone the output control logic. Now you can configure RPM, LoadFactor, TPS, speed and knock sensor windows to do just about anything imaginable. Parameter "windows" provide more flexibility. You can have them trigger above, below, or in between whichever activation points you have an interest in.
A screenshot is below of the new FPS controls. EGR output controls are identical.
