| + | * Fixed a bug in the ethanol-based interpolation between MinOct and MaxOct tables. Previously, this algorithm was incorrectly using the raw ethanol fuel correction as the interpolation value. This only affects you if you have __**both**__ the "Enable ethanol sensor" __**and**__ the "Interpolate between Min and Max octane based on ethanol content" checkboxes checked. | ||

| - | * Fixed a major bug in the previous 1G release (3.28.106) of ECMLink that caused the ECU to reset randomly while logging due to a stack overflow. To fix this issue, we had to make a huge number of changes to the base factory code to free up stack space. This type of change is risky! We've tested extensively, but please be aware of the possibility for more unexpected issues as more people exercise more functionality. | + | * Fixed a major bug in the previous 1G release (3.28.106) of ECMLink that caused the ECU to reset randomly while logging due to a stack overflow.

| * Fixed a relatively minor bug in the 2G that allowed non-zero MAFComp adjustments to randomly creep into SD operation even if you had the "ignore MAFComp while running SD" checkbox checked. | * Fixed a relatively minor bug in the 2G that allowed non-zero MAFComp adjustments to randomly creep into SD operation even if you had the "ignore MAFComp while running SD" checkbox checked. | ||

| - | ==== 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. ==== | ||

| * 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.
