v3litefirmwarechangelog [2014/03/30 11:42] twdorris [NOTE: We have identified what appears to be a bug with this release. It's probably related to the internal code structure change mentioned below. Regardless, we're going to do more testing and try to track this down before we release this version again |

| + | ===== 3.46.225 (07/04/2023) ===== | ||
| + | |||
| + | |||
| + | * Fixed relatively obscure bug that could stop engine operation on MAF-based cars if the MAF signal was lost | ||
| + | |||
| + | |||
| + | ===== 3.36.63 (02/09/2018) ===== | ||
| + | |||
| + | |||
| + | * Added option to prime the fuel rail by running the fuel pump for some amount of time after key on. The option is located on the "ECU Config→Misc" tab. It should default to 0 seconds to simulate stock behavior and you should be able to increase this in half-second steps up to, I think, 30 seconds. When you turn the ignition key on, the pump should run for this many seconds as long as the ignition key is on. If you disrupt this time by turning the ignition key off, the pump should stop immediately and then restart the full prime time again when you next restore the key to the on position. | ||
| + | |||
| + | |||
| + | ===== 3.33.114 (11/27/2016) ===== | ||
| + | |||
| + | |||
| + | * Added airflow and boost-based fuel cut options. You'll find these in the ECU Config→Fuel tab once you have updated [[https://www.ecmtuning.com/downloads.php|your laptop application]]. | ||

| * Added support for a user-editable minimum injector pulsewidth. This value can be used to prevent the ECU from attempting to operate the injector outside of its linear areas of flow. Also added functionality to disable fuel trim lean out when you've already reached the minimum injector pulsewidth. Defining the minimum injector pulsewidth somewhere just below the pulsewidth typically seem at idle on a fully warmed engine seems to help smooth out a number of transitional cases where IPW momentarily dips into non-linear areas of operation as happens sometimes when rolling to a stop with large injectors. If the injectors are large enough, it's even possible to get into a situation where you're operating the injector outside its linear range even at idle! So you may find that you need a minimum IPW so high that your typical idle is at a constant (minimum) pulsewidth. | * Added support for a user-editable minimum injector pulsewidth.

| * Made some **significant** changes to internal code structure. Although this provides no obvious changes to functionality, it does warrant mention simply due to the wide-sweeping impact this change could have on any number of other functions. A lot of testing has been done to ensure that nothing has been broken, but do keep in mind the potential is there for unexpected behavior and/or bugs. | * Made some **significant** changes to internal code structure.
