Our option used to be stand-alone ECU for $1,500+ or nothing. Now at least we have the e-Manage for $250-500, although, of course, it's far less capable. People are now getting into the Megasquirt in the Miata community because they don't feel like spending $1,500-3,000 to have full control over their fuel, timing and boost control.

I'm not a programmer, but from speaking to programmers there can't be anything magical about Mazda/RX-8 code. As for why the Miata hasn't had it, maybe the community hasn't complained enough to the right people? There are certainly enough Miatas out there to warrant a flash. Also what kind of power gains are we looking at here for Miatas? Like 50hp from a Jackson Racing unit? In other words, maybe there's nothing because there isn't a large enough demand for a lot more power within the Miata community? Many of us have come from RX-7s or other more powerful cars, there is a definite demand within our community.

There's definitely a desire for power in the Miata community, but I think you're right that we've never complained to the "right" people

I'm 6'3" and just barely fit in my car
Check these sites out: www.brperformance.com , www.flyinmiata.com , www.bellengineering.net , www.fastforwardsuperchargers.com , www.racingmazda.com , www.biggulp.net ...trying to think of any others. The little Jackson Racing M45 supercharger was the first positive-displacement blower for Miatas, but it only flows enough air for ~190rwhp on a good day, so not many people bother with them anymore.
There have been quite a few 400+rwhp Miatas (relatively speaking) and even a couple 500+rwhp Miatas, but they were all one-offs that didn't really share any parts with the kits sold by the aforementioned vendors.

I agree.... I suspect that the Miata community hasn't complained to the right people. I remember seeing something about the Mazda6 and Mazda3 communities trying to get something from SCT as it shares the same basic engine (and platform) with the Ford Fusion and Ford Focus (respectively). I think it turned out that the ECU's are different between Mazda and Ford though.
Anyway... it is obvious that there is a market for flash tuners for the Mazda community. If only people will stop wasting resources on standalones and piggybacks, and get their **** in gear on flash tuners. At least Cobb is taking a look at it now and seems to be making progress.
RB's flash. If they are still sticking with their original plan for people to ship their ECU's to RB for flashing... that sucks to say the least. To say more... it's impractical and below the industry standard bar.

No, the thought never occured to me. We just conected the crankcase vacuum hose to the inlet side of the supercharger. There is always vacuum there even when the manifold is positive. Same goes for the power brakes. Same goes for the vacuum actuated inlet tuning devices.

dont think blowback will be a problems at your boost level? I admit i am not as knowledgeable about the renasis's crankcase vent system as I am about recips, but people are already having some problems with blowback/blow through on NA engines. Sealing--who knows? Just a though. Some of us)including myself) had had this and we have installed oil catch cans between the oil filler neck and the intake(after the maf) before the engine recirculates that crap via our intakes. Some of us cap off the intake connector and make the old style downdraft tube running under the car. Our engines have responded very well. Not speaking of access to vacumn. Talking about crap in the intake air. i know I know emissions and all, but heck we dont even have a pcv on the 04-05!
something to think about.

The thing I have noticed is oil coming out of the air filter so I investigated and there is not much oil vapor or pressure in the case of this engine. what is happening is during an oil change or when topping off, if you pour the oil in too fast, it overflows and drains down the vent tube into the intake and with the K&N it is all downhill and drains out the bottom of the air filter.
Remove the tube or use a long spout funnel and the problem is solved.

Since we don't have a crankshaft rotating in the crankcase (hence the name), we don't have any windage issues. A vacuum pump wouldn't do anything for us.
On forced inducted rotaries, it is not uncommon for the pressure in the combustion chamber to leak past the oil seals in the rotors and pressurize the crankcase. Many RX-7 people use catch cans and believe me they do get used. The other option is to blow all that oily mist back into your intake. I'd definitely use a catch can for forced induction.

I have heard real good things about the Access also.
And they were always super friendly on the phone.
