Yes i am still having this issue. It has a part throttle stumble hesitation. Sometimes when you floor it , it sounds like detonation. the only way i can recreate the sound is to drive along part throttle and then floor it. sound like there are little rocks in the motor. Haven't figured it out yet. I will be visiting a rotary specialist in my area to see what we can figure out. My greatest concern is that the system is locked so there is no adjusting it.

Loube, you best give Greddy a call. That definitely sounds like detonation. You really don't want to drive around too much with detonation or you may very well blow the motor.

RX-8fan01

is that the problem ...that greddy is having wiht the first batch perhaps ?

loube

How many other people are experiencing this problem? I thought maybe it had something to do with the CEL that i had BEFORE the greddy install. I was speculating that i had weak fuel pressure before the install and now with the turbo it is obviously compounded. Has anyone contacted greddy and if they have what has been their response?

loube

Also i do not drive it all the time and i am very careful about how i drive it. We will be testing fuel pressure here sometime this week. I will let everyone know how it turns out. Oh by the way who do i contact at Greddy?

dont tell me that, iam not even finish with the kit.

Ok where do i start found a local rotary shop and he found some vacuum leaks and an oil leak. Also plugs 2 and 4 were fouled (imagine that) so we replaced them with colder plugs, car runs 95% better. Also have the unlocked maps from greddy installed on the emanage. That is great because now we can tune the vehicle. I think im going to get a boost controller. More work than i ever expected but worth it.

1) Why would you replace fouled plugs with colder plugs? Should use hotter plugs to prevent fouling.
2) You have unlocked maps? How are you programming them? The current maps that have been available are for the 1.40 version of the Support Tool which isn't available to the public yet.

loube

The plugs were fouled from before the Turbo install. I had a non rotary shop install the turbo. But fortunately i have found a local rotary tuner that has a lot of rotary experience. This is my first rotary car so i am still learning the nuances. I am a converted nissan man. I am looking into getting a 3rd Gen RX

Jeff...are the older firmware E-manages that most of us have...compatable with the new software?

No.

Well, I put my kit in this weekend. It runs like a hunk of ****. Put the new map that philodox posted in and ran 50% better. Still detonating and real choppy. I have to re retune this thing. I cant beginn to think why they would lock this map when they cant get it right.

my car is having the same thing it loses power is weird. I called geddy and talk to Benny and he told me that was normal in these car. I need help in these thing, the E-manage is locked how do I unluck it

Fanman

Well, we had a really bad power loss right before boost, and at 3500 rpm we hit detonation on the dyno. We called Greddy and talked to Benny & he told us to send back the unit, and they needed to reflash it. After he sent it back to us it ran much better. Still has a slight hesitation, but better & it seems to get better now that we have driven it about 40 miles. No detonation problem anymore on the dyno.

I suppose this goes back to the same sort of variations that were seen by those who installed the CZ version of the E-Manage on their N/A engines.

There seem to be two distinct groups of RX-8s - those that are forgiving and adaptive and those that aren't.
Why, I don't know, but it seems that it can be worked around.

I am fortunate enough to have one of the forgiving models.

I am experimenting with the MAP that is delivered with the Greddy kit and I am about to rewire my injectors using the format employed in the kit.
I don't have any problems with my own tuning - it is, seemingly, perfect - but I am curious about what is going on with this problem some of you are experienceing.
Ultimately, I think it might be worthwhile for some of you to rewire the injector control on the E-Manage and use one of my maps instead of the Greddy tuning which is causing you problems.

army_rx8

^^wasn't the first batch of e-manages sent out with the kit messed up. i thought i read that on a thread here a week ago or so?

Broke_Apex_Seal

The first map I got would not let you go full throttle. It would fall on its face. with the new map you can give it some gas but soon it will detonate. I am starting from scratch and ditching the e-manage.

army_rx8

ouch that doesn't sound good at all...detonation on a rotary i hear is very very bad (well on any engine for that matter). i wonder why yours is doing that....this is the first i've heard of this problem..granted teh kit is fairly new.

what are you gonna use in place of teh e-manage?

RX-8fan01

I hope the second batch has no problems ...i dont think it will b/c greddy will get a bad rep if they do another bad batch

MazdaManiac

iTrader: (3)

Well, not exactly. For some people, the initial shipment works just fine.
It depends on your car.

I believe the E-Manage will work on everybody's car. Then again, I'm magic. :p

jeff, can you call me man. I need your help!

that's just wierd...i wonder why that is. i know every car is a lill bit different. But they can't be that different. i thought greddy used a very conservative tune to avoid this sort of thing and make it a universal kit.

Fanman

Mine ran fine on the street. It is when we dynoed it that it ran into detonation. I hope people know what to look for when they are driving their cars with this kit on it. The re-flashed ECU had no problems the second time we went to the dyno. EGT was around 8 the whole time.

OK.

Just got done applying one of my maps to the E-Manage on Ryan's Greddy turbo install.
Seems to work fine, though it may actually be a bit too rich. But, like they say, you can never be too rich or too good looking.
He will drive that around for a few days and see how it nets out.

Attached is that map - try it at your own risk.

It is intended for the blue E-Manage and the v1.13 Support Tool.
You will need to initialize the E-Manage, which will ERASE THE GREDDY FACTORY MAP.
