Was that a serious question?

Do you have warranty and tech support on the motor you build, or the turbo you port the wastegate on?

I suppose there are different levels; people who build things, and people who buy and install things. You seem to be implying you're the latter; and that's fine. But if that's the case, you expect to pay more for that luxury. There are those of us out there who prefer to save the money, and do it ourselves. And given the fact that I can crank out a few Megasquirt ECUs for less than the price of most anything else out there, and that once built, nothing is ever likely to go bad (speaking as an embedded systems programmer on similar industrial solid state electronics), I'm not too concerned about a warranty, and as I have Google, I'm not to worried about tech support.

There are plenty of people out there who, even given the circumstances and available tools & materials, would never fabricate a part for their car. The Megasquirt is not for those people.

On a completely separate note, DIYAutoTune has released a kit designed to mount a Megasquirt into a stock S4 or S5 ECU case, and use the stock wiring harness... pretty much a PnP setup. I haven't played with one yet (mostly, I like replacing the stock harness with my own, much smaller and neater one), but it seems like there might be a market for these pre-built.

WTF does that have anything to do with aftermarket EMS and support of them?

BTW, I stand by 100% behind all my paid builds and any other work I do.
Since you mention it, I back all my work with a LIFETIME WARRANTY (yes, until I die) - any defect or failure due to my work will be taken care of by me at no cost to the customer.

You seem to have a pretty twisted view on how things work in the real world in terms of economics.
People PAY for (tech and service) support.
People PAY for warranties and guarantees - think INSURANCE.
Warranty / guarantee / insurance is a bazillion dollar industry.
Tech and service support isn't too far behind - think Best Buy's Geek Squad or Sears home repair.
Hey, YOU were the one that was asking why your MS isn't doing so well...remember?

There are plenty of people out there who, even given the circumstances and available tools & materials, would never fabricate a part for their car. The Megasquirt is not for those people.

Sure, and you're talking about a teeny tiny minority.
I can count on one hand the number of you MS experts for RX-7's...
Care you guess how many RX-7's run AEM / Autronic / Electromotive / Haltech / Microtech / MoTeC / Wolf / (insert YOUR favorite aftermarket EMS here)...?
(Don't read too much into how I listed those brands, cause I tried to list them in alphabetical order - that's all.)

Clearly, you're not getting the point I'm making. I'm saying (quite clearly, I thought), that the same people who will build an engine with no second thoughts would never think of building their own EMS, and for a very DIY hobby, I thought that that was somewhat strange.

You seem almost personally offended by the concept of a DIY EMS. WTF does economics have to do with it? Yes, people pay for those things. Hell, I work in field service for a national provider of cash registers... and ATM machines. Field service/warranty work is the biggest chunk of their profit. What I'm saying is, it seems less likely (assuming you know what you're doing, obviously the MS isn't for people who don't) that your EMS is going to blow up and need a warranty repair than your engine, and many many people build their own engines.

If you're compromising for the MS because of money then I think you should wait longer and save more for a system you'll be happy with and won't want/need to upgrade later.

We should have a Beginners Guide To ECU Tuning thread....i know I'd benefit from it greatly.

I would agree with that; if you have the know-how, you can save a lot of money with the MS. Even buying one pre-built is almost dirt cheap... $425 or so for a new generation one with a wiring harness (you have to wire the harness in, but still, that's very little labor in comparison). But if you're going to be tuning it yourself, and you don't know what you're doing, you need to be using a brand with customer service to help you out when you get stuck.

The people who give the MS a bad rep are generally people who got it because of the low price point, and have no idea what to do to get it running. Any competent tuner should be able to sit down with the controls, familiarize themselves with how things work, and be tuning in a reasonably short time-frame; the features are all there, it's just the button names that change, really.

This just reinforces my point that you have no clue what reality is.

You're ASSUMING that just because you have no problem doing this that others would not have a problem also.
BAD ASSUMPTION.

If I assumed what I can do would be easy for others to do, I would NOT be able to sell my services and products to others.
I can do automotive electronics in my sleep - I still charge others to handle stereo / alarm / EMS wiring.
Other people are willing to pay for such work and service.
NEVER ASSUME.
I tune Haltechs on cars also.
I can do this in my sleep, and it's automatic for me.
I can explain how to tune EFI in a couple hours to anyone who has a good grasp of EFI theory.
Why do people still pay me to tune their cars?
NEVER ASSUME.

What does it have to do with economics?
SUPPLY and DEMAND, period.
It involves money - you are touting that MS is cheaper, right? - and when it comes down to it, your only advantage with the MS is MONEY.

Reply if you want, but my replies to you ends here, cause it's a lost cause.
It's obvious by now that you don't get what I'm saying at all.
