You say that like its a bad thing... Believe me it's not

.

 

You don't have a Renesis engine either, but we'll see if it only being a 4-port helps ...

 

Yes, the Renesis is the problem... not the Inter-X

.

 

It would be more accurate to say they don't seem to work well together ...

 

Like I said in my previous post it's been so long that I can't remember well what was the reason exactly. I Think the adaptronics and microtech couldn't control the throttle or something, and therefore it was reading from the intake manifold, combined with the supercharger rev draw I think that's what made me have the hesitation, since it needed to read the manifold pressure. Mind you though mine was the first auto rx8 Andy at adaptronics made a adaptronics ecu for so all these issues could have been ironed out already. Nothing special with transmission oil I just use a standard one that was recommended by the transmission builders

 

Shelldude had some Auto-4 port issues to work through due to the Adaptronic from 2012 being designed for the 6-port manual engine. However, nothing like you reported. He seemed fairly happy overall with his on a turbo setup. No hesitation issues etc.

 

Interesting to know Team, I know there was a setting on the adaptronics that had something to do with Throttle estimation or something along those line to smooth out the throttle issue. However Andy did not have time to work on it when he did my car. It was a very minute issue however.

By no means did i mean adaptronics is not a good ecu, it will definitely satisfy all the OP needs, but as i pointed out if given the option of using MAF tuning, I would definitely stick with that, in terms of legal requirements here and everyday functionality i am thoroughly enjoying the tune that was done by me by Brettus.

But as the case, OP should always work with what is in front of him. In terms of Inter X and Adaptronics that is a no brainer, go with Adaptronics, the Inter X is a dinosaur in my eyes and as far as i know the Inter X / Microtech LT 10 just does not work well with the RX8.

Currently my car drives like a higher displacement rx8, meaning my powerband is exactly the same curve as the factory rx8 but just higher at almost all points. It feels great, the tuning is spot on and i guess i have always chased after that feeling of it being factory, it idles great, handles all normal function load requirements, runs components flawlessly and keeps all factory features. Adaptronic was almost there and Microtech was a fair bit off.

Hope i am not confusing you but i boiled it simply down to this

MAF: Harder process to tune but a great complete finished product and cheaper to tune
Adaptronics: Expensive ecu, bit of work. Very good finished result, car will drive absolutely fine, easier for tuners to tuner.
Interceptor X: abit like putting a circle to fill a square hole. It will Fit(work) but there will be a few gaps in the corners. Easy to Tune alot of tuners here have experience with it (Rx7 crowd uses this alot here)

 

well said

 

Update!

BOV flange was welded on, and pipes, manifold and turbine cover went off to the coating shop yesterday. We are powder coating the entire kit, and Jet coating the manifold and hot side cover. Assembly should start next week. We also found a cat back exhaust (hiding in plain sight!). Next up is a mid pipe and injector installation. There was a problem with the BHR radiator, so we went another direction with it. New high performance dual pass radiator was installed as well, no fitment issues. The transmission cooler was lost in the process, but we will use both pieces of the ACS twin instead. Second oil cooled has been hung, and new stainless steel braided oil lines will be fabricated this week.

Scott and I also discussed water injection for cooling purposes. Living in Texas, I need all the help I can get. He thinks he has a throttle body spacer, so it should be an easy install. I am looking at the AEM kit, but am interested in members opinions.

We also discussed auto transmission fluid. I read the impressions of other members, and Royal Purple seemed to be the consensus choice. Phil with the Petit kit said he was burning up stock fluid in 5k miles. That's obviously not going to work!

Questions:
For those of you with low mount setups, have you noticed passenger footwell heat to be a problem? I think I read a post about carpet igniting, but that seemed to be a rare case. If heat shields are a "must have", I figure they should go in this week.

The cat back exhaust we found is a Borla. I am a little concerned about the four inch tips. Will I have problems with the shrouds melting? I know keeping the tips clean is a lost cause.

 

Some good progress ! Glad to hear it !
Dunno why you would bother with a throttle body spacer vs weld a bush in the pipe pre throttle ?

Yes .... heat-shielding of the turbine is essential ! My shield is really simple and does the trick . Just a small sheet of ceramic/AL weave shield material placed above the turbine housing (that shields both the firewall and the intake runners) and coming down to rest on the x-member.


maybe ... get the positioning exactly right and you will probably be ok .

 

Thanks for the quick reply.

My thinking was better to use a spacer, rather than tap and die a hole in a brand new pipe. Obviously I should have thought of this before we shipped it off to the paint shop.

Brett, if a heat shield works for your crazy *** 16 psi setup, it should be good enough for us mere mortals.

 

There are bushes available that you just drill a hole and put them in ... no welding or tapping . Scott would know where to get them .......... Way cheaper .
The other thing to consider is that if you go post throttle , you MUST use a shutoff solenoid rather than a simple check valve . .... more expense for no good reason .

 

Good points on both counts. Appreciate it!

 

Pics! Post some fabrication **** plz

 

any progress ?

 

Build is moving along nicely. I need to make a few decisions on the project, and am having a difficult time weighing my options. We should have some good pictures up in the next week, and it should be completed on schedule.

 

Hey guys

Its been a busy few weeks for me. My apartment flooded in a thunderstorm, I bought a ring, got engaged, and went to my little sister's wedding. Luckily, my better half approves of this little project. I will update more once my life calms down

 

Still at the shop or do you have it back ?

 

Still at the shop. Scott was cool enough to let me put it on hold until I got the finances together and had the time to make the decisions. Everything is sorted now and we are back on track.

 

Hate to say it but ................ you should have money in reserve to do this . Not be scraping it together like that .

 

You sound surprised?

 

It was an expensive month. Like I said, it was a temporary thing (one week until I got paid for a job) and we are back on track.

 

I don't like the pay as we go concept. That's how people end up dumping several times the proposed money into it. Then get fed up and demand the car back after they're double budget and the car is still not finished. So you have to find someone willing to take on that project of fixing other peoples crap. And that doesn't happen for cheap or never happens.

 

It has worked for me. We agreed on a total cost, and I pay installments as we reach milestones. Even with several unexpected additions, Scott was within a few percentage points of where we agreed. I would rather pay as we go instead of forking over ten thousand bucks and hoping it all works out in a month.

 

I prefer half up front and half when finished.
