Turbo XS is coming out with a UTEC for the RX-8! It will have the ability to control rev limit, ignition timing, fuel, map conversion, etc. and it will only be 899$. This will be a complete plug and play system and will definitely be the new standard in our kit not to mention the ability to control things like water injection, nitrous, etc.

After speaking with Turbo XS they said they will be available sometime this spring.

 

old news

unfortunately it's just another system that's not allowed in a number of racing classes

 

How does this compare with the Interceptor, other than being less than half the price?

 

btt for Sapphonica's question...

 

As I understand it, it operates the same why the interceptor does, it simply cuts out control of the afor mentioned functions from the stock PCM and controls them itself. There website gives some decent info on their other products.

Unless you are going to rip out the whole PCM (not recommended) all ECU mods are going to be a "piggy back" unless they are flashing the stock PCM.

The problem is, people associate "piggy back" with the emanage MAF alternation technique, which is doing an injustice to the interceptor and devices like it.

 

How does this compare to your super secret ems?

 

It's not that secret. I think you know who I'm working with. I've just been asked by them not to de-cloak yet.

It's been hell waiting to find out how well this approach works out...or not.

What I do know so far is that it idles as smooth as stock, and we have complete control of fuel & timing. We're initially going with stock boost and running high octane fuel for the first round of tuning. Once I've driven the car like that for a week or so, we're going to hook up the boost controller & pressure sensor to the EMS and go for more power.

 

Be careful with the higher octane. Once you go back go the 91, you will notice a LOT of detonation. At least that was my experience. Timing for the interceptor had to be retarded much more than expect for those of us in CA.

On a different note, with the new EMS, is the check engine light on all the time? Does it retain cruise control?

 

Does it retain the knock sensor?

 

This is great news (if it pans out along with any hush hush products to come) for the RX8 comunity and for us poor folk who can't fork over 1.5K for such a product. If this is not just for Turbo/SC but can help find Inter-X like HP for NA, I'd now be willing to buy it.

Thanks to everyone that continues to make the aftermarket for the RX8 better...AND CHEAPER!

My first mod's might be EMS, REVi, RP Supercat, and Borla exhuast (not set in stone)...that should give my NA Rotary a pretty good boost in power (20-30HP).

This is music to my ears...thanks for posting!!

 

With the R flash, I doubt you'll find 20-30 HP with those mods. Besides, you'll drop so much coin on those mods it won't cost much more to get boosted.

 

yah..i would definitely tune to what gas you or everybody else will be 99% of the time be using...I have found detonation as well using your tuning technique when dropping back to "regular" daily driving fuel...in this case 93 for GA...

Now i'm not saying DON'T tune to higher octane...that will give you a "track" tune and then you can run that out and perform a daily driver tune..that's what i do...

but//i'm not you...so...just my $.02

 

REVi (3-5HP) $300
High flow cat (5-10HP) $400
Exhuast (1-3HP) $600 (this is the one I think is HIGHLY overpriced)
New EMS (10-20HP) *based on the Inter-X found $950 (if this thread pans out)

So, that gives 19-38HP, while I'm well aware those are maybe numbers and can be fantasy. I'd say with the above Mod's 20HP shouldn't be that far fetched but admit it might just be 12HP.

I'll have to go read up on the R-Flash since I've lost track to the flash I was on, I got a 2005 RX8 built in October 2004.

While true, the Turbo gives you better bang for your buck...I'm weary of going Turbo since I have no experiance with it. With that said I might do it one day but other than the REVi the above mod's would help the Turbo anyway so...you got to start some place.

Don't mind me...this is more dreaming than anything else considering my modding days are far...far away.

 

Just keep in mind that mods will give a cumulative effect, and that 5hp you got from the highflow cat, could very well negate any benefit of a catback system. It is not always 5 + 3 = 8. Sometimes, it is 5 + (claimed) 3 = 5.

 

I prefer to tune around 87 octane gas. That way anyone can use whatever they want and not worry about it. The car definitely isn't any slower this way and even if it did make less power, it would be so small that no one would ever know it. Getting more performance and lowering the cost of fuel is a win/win situation.

 

Yeah I know, I'm just going by what they claim...of course we know that is not always true (K&N 9HP air filter comes to mind...wink wink).

Regarding the thread...a cheaper Inter-X would be MOST WELCOME!

 

If you tune for 87 then at some point you have to add higher octane to your car for <insert reason here>, will the car be OK or ...?

rx8wannahave, I'm sitting at 20 HP gain from my mods. It's OK to mod for NA power. You don't need neck snapping power for a daily street driven car. The 8 is fun as a NA car also.

 

Hey Nem,
Are you still using your Canzoomer? I tuned mine to about 15 HP gain - documented on the dyno. I know I could have gotten a few more out of it if I would have installed a WB02. I could never get the CanScan to work right.

15-20HP < (Used CZ + WBO2) = ($250+$350) < $600

Still the best return for a NA 8.

-MD

 

Yep - still living the CZ dream for now

 

Thanks for the encouragment...there is little NA love around here...lol

Hey, I thought CZ was found to be....ummm, lacking???? Didn't the 8's PCM learn to stop letting the CZ work or something????

 

Would this ECU be able to change injector sizes?

 

Did you dyno +20 HP before/after with the 'R' flash?

Also, in what RPMs do you get the HP gains?

As we all know, this car is gutless down low...the 'torqueless wonder' as someone on the group said. This lack-o-torque negatively affects drivability under part throttle conditions.

Do your NA mods do anything noticeable for torque?

 

I don't understand why these EMS systems are so exciting for people. Sure they are "plug n' play" but so what? Why wait for someone to come out with something like that when you can easily go buy a Microtech, leave the stock ecu to control the manifold stuff, and use the Microtech for everything else?
