Richard,
Is this a possible theory why the AFS are rich...
When you are at WOT, the ECU is in "closed loop". Who knows if it reading the MAF, or is just basing it's fuelling of RPM and TPS? I would think MAF would be read, it is a sophisticated PCM. But none of us yet know it's exact workings. That is another project.
Anyway, if the computer saw it was doing X RPM at WOT, and was programmed to give a certain does of fuel, because a certain airflow was "known" at the RPM... And 2 of the ports where stuck closed, so less than that normal amount of air went in, then it would be 2 rich.
You could have a double edged sword. Not enough air for the RPM, and too much fuel for that air flow anyway.
Something to think about.
Cheers,
Hymee.

Nice to have you back Hymee. We shall know more tomorrow. The fact that it got better leads me to believe that they are sticking. If thats the case then it would go rich like you say.
Hey BTW I'm trying to put your canscan in but my computer spits it back out. It doesn't like the flavor. Must be that Oz taste. I't's probably my comp as it has been shitty for months. Wouln't let me put in the photo scaner either. It hates me.
Tomorrow we will try and put it into Dana's wife's laptop so gaitar junkie can do is thing. Hope this nightmare is over then. Then I can start putting the SC in and start the electronic troubles all over again.
See what I mean? The world production would be better if they let me have a Weber and a distributor. Think all the man hours and runing around this has taken. All the people who have burned up brain cells trying to help. The world would be a better place to live. I would be easier to live with.

It hates me.Email us some information about the problems you're having to support@hymee.com... and we'll try and sort it out. We haven't had a failed install reported yet, so I'm interested to know what the problems are you're having.

Sorry I've been really busy at work. Almost took the day off. Maybe next time I can help you out. I'm in Orange County, that's South of you. I'm only about 50 mi. from Fanman in Glendale.
Weekends are best for me.
The way I look at it, if she ain't at 14.5 to one then I'm ok right? Also, if she's lean it means theoretically speaking I can get a fuel manage system to richen the system to get more power.
After all isn't that the problem with the RX8? It runs pig rich.
Maybe I should dyno it again with my intake mod to see how much richer it is.

again thanks, but i can just toast a cd. the problem is lack of money and no way to get the laptop on the internet...unless i wanna pay for a copy of internet exploder to get mailed out to me.
so anyway, 6pi and vdi are actuating randomly. i popped the vdi open and shoved somethign in there to keep it open and we did some runs on the street--consistant. ok, cool
--secondaries begin to open as soon as vacuum is appliesd, and fully open by about 7" or so. smooth as glass--not sticking at all.
--vdi was the same story, only fully open at around 10" according to the mightyvac.
--couldn't test the aux ports today, but i think they're fine because when they do open, it's a smooth transition.
alrighty then...so ruling out mechanical problems, we have to move on to the control system, which we couldn't do because me=teh noob and i couldn't figure out how to make that laptop's serial port work.
now that we've partially narrowed it down, we're left with:
1)computer
2)inputs that the computer is getting
3)actuators/solonoids not getting the outputs fromt he computer (wiring harness problem)
4)maybe the solonoid and 6pi motor are going out which i very highly doubt....most of the time they either both work or both don't...but that's most of the time.
during one test run, i heard some MAJOR popcorn!!! how in the hell do you detonate a bone-stock n/a? especially one running that rich? the lack of power may possibly be the computer pulling out timing due to the knock sensor picking it up...if i hadn't heard it i swear i wouldn't have believed it, but anyone who's detonated a rotary to the point you can hear it will know what i'm talking about. that drop in the pit of your stomach... lol
in the closest thing i have to a "professional" opinion, mazda needs to fix this **** under warranty!
i'll be passing right by the shop again tomorrow, so i'll bring my laptop and see if i can manipulate it to work. if we have the datalogging ability, i'll see what kind of info i can get from the computer.

gj28,
You can download a full version of IE6 to burn onto a CD by following these instructions:
http://www.compu-docs.com/ieadmininstall.htm
The .NET Framework is included as part of the sCANalyser installer on the CD - it will be installed automatically if it's not already on the computer
HTH

so i need that for the scanalyser too? not just the canscan?
*edit*
i just checked that out and all it does is download a setup program, then i think it downloads as it installs...
i get paid on tuesday...maybe i'll go buy that whatchacallit thingy for the laptop to get that online. i don't think anyone understands how much i dispise computers...i typw like 45 words a minute, but that doesn't mean i like it!!
