Well, in your logs the boost doesn't go above 0 psi until you are only a few hundred rpm away from the stall speed of your converter (> 100 kPa at about 2400 rpm; you posted the stall as 2850), so you are starting to get some engine loading at the same time the boost is coming up. This makes it easier to build boost, with or without your assist scheme, and makes it more difficult to see the effect of just the launch assist. Listing the possiblities: your launch assist may work as you have it configured with zero load (auto trans in neutral or manual with clutch pushed in), it may work with some retuning, or it may not work. Inquiring minds want to know which possibility is correct, and it's a trivially simple test to perform.
The only problem is that this is getting way off topic.
Beings that I have source code, I can do whatever my imagination can create. I can run a WB closed loop for any situation or condition, I can do anything I want with my timing, and cyl fuel drop.
The intial topic was about having to go to a distributor because of HP gain, and then the original poster talked about the other strategies that were EST limited.
I wrote, and then looged to prove what I had to say.
As far as a standing still WOT, at full RPM, no I won't do that. It's not about the code, it's about the type of car and useage. Let's see Eightsecv6 drive his car for 70,000 miles. It's not designed for that.
The *original point* was that the aftermarket guys could generate code to allow boost, launch, and rev limiting, **WITHOUT HAVING** to interupt the EST line.
The **problem** is the aftermarket ecm locking others in, on items that only take a few lines of code to change, and/or option flags to allow using various strategies.
My car runs just the way I want. I have the source code, and can do whatever I want, once again the point of my postings, were about getting the aftermarkets not to force people into buying megabuck updates, having to rip out things, and refab others.
It is interesting in that the *pro* tuners, and vendors, are just so dead set against anything that's different from the *established norm*, or what they just happen to get handed in the way of a product. In doubt?, look at how long the Gen VI was sold with about 0 in the way of updates. If you really want to see how behind the aftermarket stuff is, get a GM race ecm from the late 80s, and disassemble that, and see what good code does. The latest greatest commercial stuff I've seen so far that's reasonably priced is still 20 years behind, code wise. And it's not that difficult to do, once one's dealing with source code, like they are. If as customers folks don't ask for better, then they'll rarely see it.
