87 TII, TECgt, T04-R....DGRR '09 build!

I use the liquid teflon tape.

That way an errant piece of the tape can't accidentally get into the lines. I have had that happen before.

[classicauto]

The fittings at the cooler, and at the engine, sure. Don't use them on any of the 37* flares though......unless the flare is damaged and leaking, the threads at those fittings are only there to provided positive pressure to the flares to make the seal, so teflon tape or pipe dope there won't do anything but bung them up.

[classicauto]

Well, she's JUST about road worthy. Going to drive it over to the shop tomorrow, throw it on the hoist and mate the downpipe, waste gate dump, and exisiting exhaust.

I've been fighting a couple issues though this week.

1) My heater fan began crapping out intermittently last year. When I pulled the dash off I found a lovely gift from CP racing, the previous owner. The logicon harness haad been molested to no end. Wires just cut with fuses placed in them, wires cut and looped back to other wires, teeing into wires that lead nowhere.......I cleaned it up and put it "back to stock" but when I put the dash in and tried the fan, no go. Grabbed my known good S5 logicon - still no go.

Somewhere, I have no idea where, there's a massive short. I have continuity to ground through both wires on the heater fan. If you try to jumper power to the + side of the fan (without disconnecting the stock harness) you just blow the fuse on the jumper wire. For now so I can defrost if I need to, I'm just jumpering power to the fan with the stock wire cut off......I'll ahve to tug the dash again down the line and really comb this bitch over......I hate finite little issues like this, I garuntee when I find I'll go "no shit that was easy" after 3 days of work

2) My laptop. Brand new acer asipre One. I bought it for the SOLE PURPOSE of tuning my car. It works absolutely flawlessly, until you're online with the ECU. Then randomly it'll go to a blue screen for 2 seconds with a bunch of stuff about terminal error, dumping physical memory - then it shuts off and restarts.......absolute BS and PITA. I'm going to resurrect the old trusty rusty unit and load the software and see what it does.

I've spoke to electromotive and they told me its a laptop issue, not specific to the WINTEC software

My luck continues!!!

AN fittings are supposed to seal though, I mean they cost enough...they should seal. It is only after everything is installed that you find the leaks and then it takes exponentially more time to fix/tighten.

No, plumbers tape or plumbers spooge (as I call it) is a BAD idea on an fittings. The 37* flare seals the line, not the threads like NPT. Thread or spooge can only muck things up.

Nice, let the finger pointing begin. Gaurunteed if you called the laptop co they say it's a software problem Either way its better than my laptop. POS takes literally 7 minutes to load the Motec software. I can't justify a new laptop though. I usually just leave the thing booted up too. I hate that thing

Good luck Joe, let us know how everything turns out

[need RX7]

lol spooge...

[classicauto]

Well I've got a few miles on her.

Wish I could tell you how many, but it appears I haven't clipped my speedo cable into the cluster all the way

Fixing that right now. The laptop *seems* (knock on wood) to be working ok, and the tune is actually going well. Had only gone about 20kms by the time I got most of the vaccum stuff dialed in. Now I just need to burn off the rest of this old fuel, toss in some Ontario High-test and start lighting the wick

PS: The TEC drives the tach slightly more accurately then Mazda did!

[classicauto]

Alrighty!!

I got back from the road trip and from DGRR, AMAZING event that everyone should attend always! DJ, I'd have come out saturday night but kevin had me all pumped up for a sunrise run (4:15am EEEEK!) then left us hangin' so we went alone I was all set to drink loads american beer too...........next year!

Some interesting data I found while on the road trip (OH BTW didn't blow any engines this year -yet- so please please hold the applause! ) for starters, gas mileage.

50 Liter fill up, all highway driving, 525km's. In otherwords roughly 9.75-10L/100kms. For my 'merican friends - approximately 23MPG.

I was freakin' blown away.

Now obviously, this is an extreme highway test. we would litearlly fill up the car, get on the highway, lock in cruise at about 75mph and run until the tank was empty. If I boost the car......well, lets just say that I get viper fuel mileage! soudns faster!

That was running above 16:1 ratios as well. Its kind of wierd, but my wideband only reads to 16.00:1....so tuning those areas was "fun". I had to bascially do it blind and just run by what the car was telling me/how it feels, but I was surprised when it was still driving well that light loads/cruise areas were pegging the wideband full lean. The actual ratio couldn't be much more then 16.25 though, I just can't see that getting close to 17's would be enough fuel for it to run.

After usingthis ECU for a while though I have to say I really really like this software/way of control. Save for the stupid go$*D0vsaj mother%*$*$&ing laptop crashing on me its very nice.

In other news I've gotten my AFR's up top cleaned up all the way to redline at spring pressure - about 210KPA ABSOLUTE, or 16ish psi. The spring is supposed to be 0.9bar, but I just goes to 15 and gets real happy? I don't know. I can't wait to try frigging around the gain control though - this thing seems to come online pretty good with no help at all, that should really wake it up.

Any profecB experts out there have any advice for a guy wanting better RESPONSE, without much higher peak pressure? I do intend to have a *kill setting* though but I'll figure that one out myself

[FC3S Murray]

does the Profec have a "GAIN" setting? My Blitz SBC i-d has this setting which increases reponse OR spool time. A little goes a long way BUT too much and you spike.

[classicauto]

Yes its got a gain setting, I'm just curious as to how much that will help if I have the actual solenoid duty cycle really low. Wanting to boost at or near spring pressure but increase response. raising boost AND response should be pretty easy.

I'll just start fiddling around I guess thanks

[classicauto]

Its so much fun. Apparently my car thinks so too!!!!!!!!

I popped a seal. Again! w00t

Call me a sadist, but I'm actually a little excited about this one. I'll get into that in a sec, but first off let me list for you guys what the "classicauto solo" rebuild has stood up to so far:

1) Installed with the E6(HEX!)X when it was still having trigger issues.
2) The first 10 mintues/10 kms the engine had on it were (after a short idle) done at 15psi
3) Over 45 dyno runs
4) Somewhere around the 40th dyno run - the fuel pump fuse blew (clogged filter) and STONE COLD SHUT HER DOWN at about 18psi/5500RPM
5) New EMS, larger turbo....
6) "tuned" by me
7) Driven to the gap, "tuned up some more" by me with Masin behidn the wheel
8) Ran the shit out of it on the gap.....
9) Drove to the keys and back home......(over 7000kms)
10) Ran the shit out of it around here "tuning it some more"
11) Had the water injection off for the last tuning session, and forgot to turn it back on after
12) Blew to bits at 20psi (yes 20, from the T04-R) at around 7,000RPM

All in all, about 17,000kms of shitty tuning and hard driving. Its a hell of an improvment over my previous history of popping them in vaccum, or at 2psi while passing a truck.......on freshly rebuilt engines.

I'm excited about this for the following:

1) I get to inspect my first entirely solo rebuild
2) Inspect the coolant jacket mods I did
3) Inspect the EGR elimination to the sleeves I did
4) I get to install my NRS ceramics!!!! w00T!
5) I get to give up trying to be a tuner, I'm a body man for fuck sakes!!

I'll post pics of the carnage when I get it apart, but let me just say it blow'd up real good. Much better then before, there was only about 300C of EGT on the rear rotor....

I'll never use anything else but a rotary..........in my rotary car The skyline GTR that I don't own yet but will one day can stay inline 6 though

EDIT: I'm in touch with Logan from Defined autoworks, waiting to hear back a few things but I'm planning to use his mountains of skill (and dyno) to do the tuning on the new keg. I may be hard headed on getting and keeping this bitch running on both rotors, but damn these new seals are pricey. I'll let a real master do his thing.....

[JShiz]

lol. good luck

[need RX7]

Damn dude, are you sure you never pissed off any gypsies or anything?
At least you're staying positive about it. Good luck with this one.

[classicauto]

Thanks guys. Before I'd say I might have pissed off gypsies - just because the failures were random. But its actually satisfying to have a "regular" failure.....at least, one that can be explained to an extent.

[TehMonkay]

Newer laptops can be a bitch with that stuff, thats why i bought an older thinkpad with a serial port.

Yea I flip flopped between buying an old refurbished dell with a serial port vs. the one I have now.....the cost was the same for new vs. refurbished so I went the route I did (it has XP though, no vista for me) but sometimes shit happens....I *think* i've got it figured out though with registry fixes and a few little things that my friend did that I do not understand at all

Damn Joe, sorry to hear that. WTF is up with our luck? Are we just cursed? Did we burn down city hall and rape the mayors wife in a former life? Maybe torture some animals or sell kids into prostitution? I don't get it.

I think most people would have by this point. After my motor blew, and after we pulled apart the donor and saw the clusterfuck ahead of us I just started blurting out everything that we needed to do and the parts that I needed to buy, A very good friend who helped out alot looked @ me and said, "jeez Bri, you just don't know when to quit do you."
Without even thinking I responded with, "Nope, and it's a strength that most don't have."

Looks like you have that strength too Joe. Good luck and we demand pics of the carnage

Yea I was reading your thread yesterday and caught some wind of an overheat or something? I have no idea what it is, I think maybe if you're the type to never give up, life gets pissed off and throws all kinds of crap your way. But I'm sure you'd agree that rotary failures do not equal life failures - and in life I'm a very lucky man.

And you shall see pics of the carnage for sure. Just have to get at 'er...

It is nice to know that your blow out was from a simple brain fart and NOT some unknown mechanical bad joo-joo failure. Much better luck 4 you given your past head aches.

I have come to the realization that this is what comes with DIY high HP rotary tuning/building. Deal with it or go home.

Good luck with this build bro.

Cracked iron! Dayum, thats new territory for me. I'm more of a chipped seal and or completely missing seal guy But I hear ya, thanks for the kind words.

good to see you are too down about it. so what do you think caused it? no water at 20 psi?

Thats what I told the car when I put in the TECgt!! But like I said I'm alot happier about this type of failure then the previous ones. And on the note of the ceramics.......

I just measured up all my housings this morning that I'm using on the build (used, but almost new) and I found a couple of things thats making me lean away from playing my ceramic seal card. One housing has a *TINY* little sliver of a crack just starting around thespark plug boss....and the other housing has a nick in the compression section from the blown engine in florida last year. They will work fine (I've had both inside engines already) but I don't want to waste my ceraimc seal on a housing that won't bed into the seal fully. Apparently, thats what happens - the housings break into the seal, not the other way around like normally

And I don't currently have the bread for OEM housings so I think I'll just stick some more OEM seals back in this and save them for another build. This engine lasted a while on my shitty tuning and with a lot of BAD things happening to it. If I get the rest of the season out of another OEM seal engine with a solid tune - I'll be happy.

The failure I think was yes, mostly attributed to lack of water. I think though, that I damaged something when I got my car running at full boost/RPM when I got back from the road trip though. After that night of tuning I was driving back and noticed a little bit of a miss when cruising. I thought it was plugs (and they were shot.....) but they didn't make the miss go away. And after that, I'd ran it out at full song maybe half a dozen more times before it popped......maybe I'd cracked something, and then it completely fell out later on. But, lets count:

I tuned some (not much) boost aroudn here
We tuned all around the dragon
I tuned on the way to and from florida
Tuned once around here
Tuned twice around here (when I think I damaged something)

And you know what my tuning is like masin! *floors car, takes off, engine floods with 9.00:1AFR* Repeat, and the same happens, but this time 500rpm later I'd cleared it up about 90% around here, but still - thats alot of stress to put on the thing. There's probably 4 tanks of fuel used just hammering it trying to sort out the fuel......

With the water though it may have still been running - who knows. I can't fault my build though, I had sworn up and down that thing was blown 3 or 4 times before when all the fuel pump fuse crap went down.
