Can someone confirm that the "plug-and-play e-manage" from a Greddy Turbo kit will also work on a N/A RX8? Does anyone have this setup?

I think it should work. Just clear the "turbo map" and load a new map.

 

the car ecu will change what ever setting you put in .it not worth it.

 

- raises BS flag -

 

Check out the canzoomer. Its basically a repackaged emanage for NA cars.

 

RAISES FINGER

 

Rx8on19 also you can call greddy they are getting ready to switch to the new emanage because they had many problems with the older units. from what i heard they say they needed to add something to the harness and then they should start to ship with all the new greddy kits.

I had the canzoomer and after a while the car changed all my setting done by the tunning shop and loss hp sad but the cars ecu is really smart

 

Not really true. Have you done some data logging to conclude this? Speculation or butt-dyno isn't the best way to know for sure. From my experience with Canzoomer/E-manage, the ECU only tampers with lower RPM changes you've made. For the most part, low RPM adjustments didn't prove to be worth the trouble. The car runs funny at times, faster at times, and then you start noticing loss of MPG. My car was running too rich since I kept leaning out the low RPMs every time I see my charts going rich again.

The high RPMs, however, were more supportive of my adjustments. The ECU doesn't compensate to try and cancel my open-loop maps. If my street tune charts showed a lot of inconsistency from time to time, while running the same map, that's a sign of the ECU compensating for my adjustments. That wasn't the case for my car.

 

if it would have been tuned correctly you wouldn't have had that problem... its funny how i keep hearing otherwise yet after a year I still haven't had to change my settings and have gained a substantial amount


as someone else mention, if you are just looking to do this on a NA car check out a canzoomer unit which is a repackaged greddy with ignition circuit that has the correct harnass and boxed so it fits under the stock ecy cover

 

Thanks for your feed back guys. I just want to know if some else out there had tried to use the Greddy harness on a N/A RX-8. If not, I'll try it out and let you all know my results. I didn't want to re-invent the wheel.

 

Yes i have 6 dyno pulls and the also used the new scanylizer,and the shop hook up a senser on my manifold. also i was one of those people who argued with everyone on this forum when they said there no gains from the canzzomer until i started logging my data and lost about 6 to 10 hp yet my butt dyno thought i was quicker you will not lose the tunning overnight i say about 1 week .

 

Sorry to hear about your experience smrx8. My logs have been taken almost twice a week for the past 3 months now. This is the longest time I've been active about logging my car with CZ on. Nope, not overnight at all.

I also thought the CZ was ruining my adjustments as time went by before. The dealership found out that my plugs were fouling little by little. I didn't know about this until I was having random misfire. The new plugs have solved the problem. For me, the loss of power had to do with other things, and not the ECU's compensation.

Three straight months and my car has been running way better than before with the CZ on.

 

Xyntax,

What performance mods do you have on your 8?

 

just make sure you don't do anything under 5500 rpms to the fuel map and your maps will be set for as long as you want them.

One thing to note, the greddy rx8 harnass will only be good for adjusting the fuel map. On an NA car its also helpful to adjust the engine timing, which to my knowledge requires a homemade circuit added to the greddy ignition harnass to adjust the voltage and keep from cooking your ignition coils. You should be able to find on this site how to do it from MazdaManiac...

 

r0tor,

Good ponits. So guys with the Greddy turbo kit can't adjust timming? That Sucks... Why do you say not to add anything under 5500 rpms? Will that trigger a CEL?

 

The general deal on tuning an Emanage is this...

The 8's ecu is a run of the mill "adaptive fuel strategy" unit. It contains a fuel trim map to adjust its own map for how the car changes over time (sort of like what the e-manage is). Basically, in closed-loop control (generally under 5500 rpms)the ecu uses its orignal fuel map, then looks at the O2 sensor to doublecheck the a/f ratio, then adjusts the 2nd fuel trim map for any errors that it will use next time it reaches those conditions. The part that makes it adaptive is the ecu can only adjust the fuel trim map in closed loop conditions, but the part of the map in the open-loop areas (above 5500 rpms) is actually linked to the closed loop area of the map - so a change at 3000 rpms will show up in say the 7000-8000 range.

So the bottom line is that is you keep your adjustments above 5500 rpms, the ecu will never be able to undo your adjustments. If you make adjustments lower then that, the ecu will figure out something is fishy when it does the doublecheck with the O2 sensor and correct for your adjustments... hence you here so many complaints about the ecu wiping out their adjustments.

You can get away with slight timing changes below 5500 rpms though, but i haven't seen any advantage with them.

The unit is installed and working. Thanks

 

Glad to hear it worked out!

 

Any "butt-dyno" reports? What kind of tuning have you done? I assume you've only modded it above 5550.
