 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. ​ 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.

 ===== 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. 
  
  
-===== Individual deadtime control ===== 
-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]]. ​ 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. 
  
-In addition to controlling individual deadtime, we will be increasing 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 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.+===== 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.

 +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
 + 
 +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...

 +We will be using this connector on our GM MAF adapters to finally provide a true plug-n-play solution for 2G DSMs.  The 1G guys already have this because their mating connector already exists. ​ We're finally catching the 2G guys up.  :-P

 +Prior to this connector we (and everyone else) had been using a Delphi equivalent that just happened to sorta shove into place but was seriously lacking in a number of ways including the lack of a locking tab, improper fit and no sealing mechanism at all.
