Has anyone purchased an ecu from peeps@vems.ee?

Smacks of elitism and arrogance, with little substance to back the attitude of superiority.

Certainly, there has to be some everyday solution after 3+ decades of experimentation, and quantum leaps of technology since the 1980s, nyet?

No. You explicitly stated that you neither wanted or were able to learn the skills required yourself, OR pay someone who had.

Unrealistic (or at least, the far end of the probability curve)

Where are you smart guys?

the smart guys are figuring out how to do this ourselves on a MUCH smaller number of cars for a MUCH smaller total addressable market

The less motivated or able are paying the above smart guys who have the skills and are willing to share (e.g. taking it to a professional tuner)

the rest are complaining that no one is handing this to them for free on a silver platter

I truly do not want to have to do a Masters degree program just to get a car running, and I don't want to put someone on salary just so I can drive my car, and I really don't like the idea that I have to pay someone big bucks to "tune" my car.
Sooooo, is there such a beast as a simple idiot proof system that doesn't require continual and perpetual investment of time and money to get a turbo car running, and to keep it driving?

Somehow after several years of doing this project, I'm raising this question. Rather late, huh.

As far as why do his, first, I didn't want to rewire a bunch of plugs and stuff. His is plug and play, other than tuning. Second, he has been super helpful with ideas.

I would think there could be an appropriate "ready to go" tune for most of the popular applications. Stock compression 3.2 or 3.0 with .5 bar boost, stock CIS to fuel injection for example, both of which are fairly common in the P car world of boost. There are several supercharger /turbo kits for domestic cars that come with a baseline tune that's good to go unless someone wants to extract every ounce of power.

So, I’m not sure why many people think or envision this whole EFI thing as a plug and play situation? There are too many variables from engine to engine for this to be a one size fits all situation. Manufacturers spend millions of dollars in R&D plus production to find their one size fits all happy medium based on regulations and mandates. Aftermarket manufactures provide a happy medium to get you going and you tweak to your needs.. in essence, take the guys from this board, in most cases some of the parameters between your builds are gonad be different, so what you want is for the system to detect and compensate for that difference in build? Well, that’s where your tuner comes in. As far as the self-tuning or self-learning systems go, hmmm.. I got no answer for those (nor do I know enough about them) but I can’t see how they would be able to tune to optimum performance.. and I’m not sure that the manufactures have really made the kind of capital investment it takes for “real” machine learning or Ai technology at this point.. unfortunately I missed SEMA this year and it its available, that’s where you’d find it. Anyway just my random thoughts.

With VEMS, if I’m not mistaken, part of its beauty and value-add is in the out with the “old Motronic box and in with the VEMS ECU” to the factory harness (3.2 -3.6 ).. or is it a piggyback ecu? I think that’s great because one of the issues is installing or building a new harness for your given choice of ECU. The stock harness is not a bad piece to leverage considering it pretty much covers all your parameters to begin with
I may even look into the VEMS as well for one of my projects, a hot rod NA 3.4 - engine ran well before but was limited by the use of Motronic tune and MAF.

baloo, I've been around a quite a few of these type of self-tuning systems, and have been impressed at times with them and telling people to stay away at others.

You can easily bolt one of these on your 911 if you were to make a Holley 4150 style carb based intake.

F.A.S.T, FITech, and others make these systems. One of the ones I "tuned" (had cold start issues), had the best throttle response I've been around on a very large American V8.

They are VERY easy to program.

If you can fab an intake, you can easily drop one of these on a 911 for cheap.
