| ===== Release date ===== | ===== 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. | I know the first question coming is "when". As soon as we know, we'll post it. I promise.

| ===== V3Lite ===== | ===== V3Lite ===== | ||
| - | As promised, we have released [[http://www.ecmtuning.com/product/v3lite|V3Lite]] for the 1G and 2G DSMs. We have posted a [[prodcompare|product comparison table]] for review. | + | As promised, we have provided [[v3litefirmwarechangelog|RPM-based fuel and timing adjustments]] in V3Lite to match the functionality people loved so much from the full version. We have also added full MAF compensation so you can make use of the [[v3mafadjcombft|Auto MAF Adjust]] function. Both of these functions were immediately requested by all the V3Lite users. We never knew how much people liked those controls until we released a version of our product without them. We've corrected that mistake. :) |

| - | We do already have a few changes in mind for this product. In particular, we expect to move the injector compensation from direct access into the ECU Config area because unlike most other direct access tables, changes to the deadtime table and even to the global fuel scale are just more convenient in the ECU Config area where they can be made as the engine is running. | ||
| - | And by **popular** demand, we are moving the RPM-base fuel and timing sliders into V3Lite. We were simply not aware that so many people found those sliders so useful. They work great and they're super easy to use, so I guess we shouldn't have been too surprised. So expect those to be ported into V3Lite very soon. It's actually at the top of our todo list. | + | ===== Full V3 ===== |
| + | We have nearly completed the release of individual deadtime control. If you're not familiar with this, we have a video up of some [[http://www.youtube.com/user/ecmtuning#p/a/u/1/cO7fPmAxG50|sample results]]. Basically, you can dial in different deadtime values for each injector. This lets you fine tune the behavior of injector sets that aren't match perfectly at idle pulsewidths. Most places are not able to properly test injectors with our ECU drivers and at our typical idle pulsewidths. So while the injectors they ship may be well matched at 100%, 80% or even 20% duty cycle, they can still be VERY different at idle due to variations in deadtime from one to the next. | ||
| - | ===== Individual deadtime control ===== | + | In addition to controlling individual deadtime, we have increased deadtime resolution as well. The factory 1G ECU runs with a resolution of 24usecs and the 2G runs with 15usecs. ECMLink normalizes these so that both are 15usecs, but even this can be too coarse for large injectors. Running 1750s with 15usecs "jumps" in injector pulsewidth at idle is just too much. |
| - | We've tested the idea of doing individual deadtime control and we really liked [[http://www.youtube.com/user/ecmtuning#p/a/u/1/cO7fPmAxG50|the results]].

Running 1750s with 15usecs "jumps" in injector pulsewidth at idle is just too much. | + | We have increased this resolution to 1 usec (!!) to match the code inside the ECU (hardware limitations still limit this to 4 usecs, but the code tracks pulsewidths down to 1 usec for increased precision). Doing so makes for much nicer idle quality with large injectors. |
| - | We will increase this resolution to 4usecs to match the hardware limitations inside the ECU. Doing so makes for much nicer idle quality with large injectors. | + | In addition, we are toying with the idea of working on boost control logic inside the ECU next. We hear the stock EVO8 has some nice functions and features in it that we may just have to port over to the DSMs... |
