You are not as informed on this subject as you think you are. Your statement is false.

Let's face it, the rotary needs to be force fed to make HP & torque on par with its looks and handling, not to mention with its competition, which is beating the stuffing out of it, sales-wise.

Microtech =$$ and that's sans harness.

A used and perfectly working microtech can be had for 600-900 easily.
How is this expensive? Isn't the interceptor $1800?
In fact, I know someone selling a brand new in box Microtech LT-8s with harness for $900 shipped.

so $900. Then you have software at $100-150. Then if you want to have map switching capability like the UTEC, you need the hand held controller $100-150.
So why not get excited about something that can do the same for $2-300 less. It's all moot anyway, because there's no product for the 8 as of now, so it's probably not coming at all.

The ecu comes preloaded with a map, but you must buy the software to tune it yourself.
You sellin' Microtech's or something? The Utec is cheaper (or would be if it existed), and is therefore worthy of looking at instead of the Microtech. This argument is silly, and I'll take no further part in it.

Well that's too bad the official site lists the software seperately. Lots of online venders and on Ebay has the software included in the package, for a good price.
No I'm not selling Microtechs, I'm just trying to show people there are more options out there than they think. Which also includes Haltechs, Megasquirts, Wolf 3D, and so on.
I wasn't comparing to the Utech either, since theirs isn't even out and we don't know how it will perform. I was talking about the Microtech versus the Interceptor.

well please explain then. As far as I can see, and as I stated before, your EMS options are:
1. Complete standalone unit such as a Motec (expensive and not very practical since you lose several features such as Radio, Powersteering and A/C)
2. Reflash - several options are being worked on, none available yet.
3. "piggyback" - ranges from the emanage at the low end to standalone's such as the microtech "Interceptor-x" which control some key engine functions, but still use the stock ecu for others, hence the term "piggyback"

Why don't you go on to quantify your statement since you apparently know something the rest of the planet doesn't?

You're wrong too, you need to think outside the box 
for starters, the Astra Racing ECU is neither an external piggyback, standalone, or flash. That's not what I was referring to, but it proves my point.
not sure why you're panties are in such a wad about it though
if you want to say that I'm FOS and don't have a clue that's ok but there's no reason to take it so personal
if you think you understand everything RX-8 related known on earth you're kidding yourself though, even I'm not foolish enough to think that ... this site is good but it is not the all inclusive definitive knowledge bank for all things RX-8

I'm using the term piggyback very loosely to define any PCM modifcation that does not involve a reflash or all out replacement. This may be causing confusion. I don't know a better metaphor for allowing the stock PCM to control certain things while the "piggyback" device controls other key features.
I went to the astra racing site, but I can't find any info on their ECU, therefore, I don't know their ECU strategy. I'm not sure how any modification could fall ouside my three broad categories, but I never claim to be an expert.

And here's a direct quote from HFAlex himself:

About tha MAF sensor, i read a lot of people think it is the mai problem, but i don't understand why since we had no problem to manage absolute pressures up to 2 bar just only with a few little changes.

I don't know what is involved in removing the CPU, but I doubt it's that complicated. The worst case situation would be desoldering the actual chip from the board. Best case situation is the CPU is on its own board and you just disconnect that board, close a jumper and the board itself is then used to program the CPU with whatever map you want. Getting that map right = the trick.

its not exactly a flash though because they are not altering the OEM fuel tables - instead placing their own code in the processor to overide the factory fuel tables...
... from what i gather anyway

Okay, so rather than start a new thread I resurrected this one...has anyone actually used or know of anyone that has used the Utec? It's cheaper than the interceptor and appears to have the same capabilities...
