Thanks.
I was searching the web during the afternoon including ebay, but missed this one. I also talked to a rebuilder who listed a unit for the RX8, but when I was talking to him he didn't even have the schematics to rebuild a RX8 ECU. He did give me some info on the numbers on the computer. Mine is N3H6 18881G - he said numbers ending 9 are dealer replacements - for what it's worth.

 

Here's my version showing the basic kit with Greddy part #'s and decriptions.

 

Ok I´ve been reading this thread over and over trying to get a grip of how to connect the hoses to my Profec B Spec-II boostcontroller.
As far as I see it, there are 3 hoses to connect... com-port, no-port and the hose from the main unit inside the car. Can someone PLEASE explain where to connect these?
Pictures would be great! Thanx alot.

 

These pictures should be pretty self-explanatory:

 

Yes they are.... The only "problem" I´m having is to find the point where to connect the hose from the main unit. In the manual it says "connect to the fuel pressure regultator" wich I cannot find. But when looking at the first pic you attached it seems like it connects to the hose where the bov connected. Am I right... The pressure is the one for the e-manage, right? (Just to be 100% clear)
Thanks for your help MM! Highly appreciated!

 

Yes. Just split the E-Manage pressure sensor signal hose with a vacuum "T". Sens that to the pressure sensor for the boost controller.
Hook the "NO" connection to a fitting as indicated in the fixes at the top of the thread.

 

LOVELY!!! Maybe I´m not as stupid as I thought... Thanks for helping out.
...and it really sucks being on this side of the atlantic when it comes to experties on 8´s.

 

Just for anyone who is interested,my car is now on the road with aGreddy kit,severed P2 injectors,Mad Dogs map #13 and the R flash.It idles well,runs well,transitions well to boost.The only thing I do not like is some backfire in the exhaust on the overrun.I am only boosting to 32kpa(say 5psi) but the acceleration is explosive by comparison.Now for a period of tuning and boost increase.

Ps I should say thanks to Mad Dog and Benny at Greddy who helped wth the Greddy Support Tool.

 

Wow. You have the R flash?

I thought that severing the P2's might help those with the R flash, but I think you might be the first to try it. Glad to hear initial results are promising. Keep us posted!

NOW this is getting interesting... I have te R flash as well and have had some smaller issues running it. Next visit to the garage I´ll definately cut off those wires! But of all the maps that has been posted, wich one is Mad Dogs #13?

By the way, I replaced the stock cat with the SR Motorsports cat, and it sounds freaking awesome!

 

It is post#97 on this thread.For comparison I am running the factory cat with the new Mazdaspeed cat-back.For those who suffer "drone' with the new Mazdaspeed catback,it can be solved by adding a turbo!

 

Wow I'm really surprised it works so well with the R flash. I thought Benny had said that required some kind of hardware change. I'm even more surprised that you're able to use the same map that was setup for the M flash. What are your AFR's?

 

I have not got that far yet.I spent my time trying to set up my home made cold air intake where the K&N filter can be cleaned without removing the front bumper---unfortunately it does not idle worth a damn so I have reverted to Airinx while I think about it somemore.
The weather up here is not suitable for testing yet,when I was out Friday it was about 35F and my Dunlops are dodgy under those conditions.
W hat I can say is it idles absolutely flat at 820rpm,lambda is 0.999+/-0.005,(that Mazda ecu is great!),my cruise control still works,drivability is very good,transition to boost is transparent(you need the gauge),I am developing significant boost at 2200rpm due probably to my recycle valve set up and then it is virtually seamless up to 7500rpm.My LTFT and STFT have not changed and are at 0%.
It is way faster than either of my TIIs were acceleration wise and drivability is about the same so far.
I will post lambda values when I do some real testing.

 

nice...

 

hmm perhaps it is time to get off the fence

 

R-flash shouldn't make much of a difference using the MadDog option.
The P2s are independant and the secondaries can't do much to get around that.

 

Just one other thought---I am running with a restriction orifice in the signal hose to the Greddy pressure sensor.From my TII days this device was essential for smooth operation--I just used a TII one I had in my bit box.

 

Do you know the size of the restrictor you're - I'm using .040" (#60 drill) on both the line to the GReddy sensor and the actuator.

 

Well I did not actually measure it ,but it is supposed to be 0.5mm,say roughly 0.020 inches.I only use one sensor for the e-manage and the e-01 boost controller.The boost display on the e-01 is very stable.

 

What the hell are you guys talking about? And what does this TII do? I did a search on Google and I’m more confused than before. Not that it takes much to confuse me.

 

The TII is a second generation RX-7.
The restrictor that is being discussed causes the vacuum/pressure signal from the manifold to the E-Manage and/or boost controller to be smoother and more predictable by reducing its volume.

 

Cool. Were do I get one?
Edit:
Did a massive search (exaggerating) and I learned that its also called a pill and an orifice, I still cant find a part # and exactly were this thing is installed and how does it work? Sorry for all the questions but I’m an information fiend.
Edit:

 

Just another fix - I'll post it elsewhere as well:

Switch the first rotary switch inside the E-Manage from "B" to "8" and all four ignition circuits become active.
This means, you can wire the ignition harness and control timing on the leading AND trailing plugs.
I don't know why I didn't try this sooner.

This doesn't seem to affect any other aspects of the E-Manage operation and the RPM is still correct.

 

..and in a few months we have made the emanage piggyback a standalone unit. Great fix Maniac! As soon as the roads are clreared of all snow, dirt and **** I´ll have plenty of emanage-stuff to do.

 

I finally did fix #2 a little less than a week ago, and am very happy with the results. Thanks guys!
