Whats up everybody i jus put greddy kit on my 8 and i was havin some trouble with the emanage, and i have been searching the forums for some help but havent found much. Mazdamaniac has helped alot but i havent been able to pin point the solution to my problem. For some reason im overboostin by alot. It was my understanding that the kit was pre-set for 5.6 psi and im getting reads on my boost gauge of as high as 12 psi! Its really weird because i put the kit on saturday and since then ive only tried full throttle twice and both times the boost gaue shot up extremely high. This is my everyday driver and i chose the greddy kit due to what i have read about the reliability of it. Plus i figured with it staying at 5.6 psi it would be pretty safe cuz its running such low boost. As long as im at about 30% throttle it stays around 5/6 psi but if i press the gas any further it goes up. another thing thats crazy is as long as it stays around 5 i can really feel the turbo doing its job spooling and it pulls the car hard as hell. But once i get past about 6grand the boost starts to go up but i dont feel the car acclerating anymore. Im thinking that has something to do with maybe not having enough fuel at the higher rpms for the amount of air thats coming in.(thought the emanage controlled that too) Im scheduled for a tune next weekend but i would hate to detonate before then! I was also wondering if there was a way to maybe reset the emanage ultimate since i thought it was responsible for keeping the boost at 5.6psi. If anyone could help me out it would be greatly appreciated and if someone has already answered these question i apologize for wastin u guys time but could u point me in the right direction to that thread cuz i havent been able to find them anywhere. Got plenty of pics too if anyone wants to see the process of me putting the kit on, greddy made it kinda easy just a few tight spots.

Mazdamaniac would be the MAN to discuss this with. Sounds like the boost control is out of whack.

Do you have a boost controller?

Kjdakilla03

No i dont have a boost controller yet, just a boost gauge... I really dont wanna do anything to break my car so i didnt buy a boost control right off cuz i know the first time i lose a race i would just crank up the boost for a rematch! I broke my 89 tII that way! i figured about 6psi would be good for an everyday driver and still enough to kick a few butts. Could there be a problem with my wastegate or did greddy give the emanage full control of boost? How do i find the legend Mr. Mazdamaniac?

my friend had a similar issue, but then he bought the blitz i color and set his the boost to 5psi. After that the car seem to run pretty good. I dunno, im not too familiar with the technical aspect of turbos. You are gonna have to email MM cuz his pm inbox is full.

I think i got the problem figured out guys. Thanks alot for everybodys help.

mikeschaefer

Well what was the problem? It might help someone else out too when they go searching and find your thread later on!

Kjdakilla03

Ok this is gonna sound really stupid but my problem wasnt really a problem at all. Im a lil embarrased

to tell this story but here it goes... I got some really good friends at mazda and since i sale cars at a used

car dealership which is in the same auto mall as the mazda dealership (and owned by the same guy) i

always go down there if i have any trouble and they kinda let me take over a bay! anyway, we hooked the

car up to the scanner to see what the problem might have been and it showed that i had like 24 misfires

on one coil. So we put a new coil in (i can get the coils really cheap on my employee discount) and I still

kept getting the same jerking problems. then we hooked up a different boost gauge... We kept my boost

gauge hooked up which is T'd off of my blowoff valve and then hooked up the second gauge on a "T"

coming right off of the wastgate. We took the car on the hwy and my friend sat in the passenger seat with

his mac tools gauge and while i watched my gauge on the drivers side, he watched his (which we had

running off the wastegate up thru the passengers side window) What we found is kinda

embarrassing . As i accelerated, my boost gauge would hit about 4.6 psi my car would start

jerking (misfiring) and then my boost gauge (the one on my side)would shoot up to 10-11 psi. My friends

boost gauge, even thru all the chaos never went over 5 even while the car was jerking! We ran

this primitive test a few more times and realized that my problem was not really a problem at all at this

point. Especially without tune. It was hitting the fuel cut! Just like its supposed to do! The

emanage in this kit cuts fuel at 4.6/5 psi and that is a good thing but a very sucky thing also. We came to

the conclusion that my boost gauge was a POS! and it was. Folks at home i learned a very valuable lesson

here. Its not worth it to buy the cheap ebay stuff all the time. Especially with something as important as a

boost gauge. Not knocking ebay at all cuz i have gotten countless items from ebay but this was one that i

really regret buying . Once we realized what was going on we just laughed about it and took it

all apart. Knowing this kinda gives me a new outlook on this kit and on how bad i need to hurry and get it

tuned. I can honestly say i am slightly dissapointed but only in myself and for all the wrong reasons.

Greddy did a great job on this kit from top to bottom (in my opinion) in reference to what it was built for

and how it compares in price to the other kits that are offered for our cars. It creates low end torque that i

have never seen and it is very reliable in terms of bolting it on and just riding out. Not to mention it is just

overall a faster car now . Plus the fuel cut is pretty much saving my motor from overboost right now! The

only frustration i really have thus far is that u really have to feather the gas to keep it rom going into fuel

cut mode and misfiring. Especially if u are racing! The appointment i had crashed cuz my friend from atlanta

told me i should go to Top Speed. Im tryna set up an appointment at TOP SPEED so i can get this thing

tuned. I have left about 3 voice messages and i havent heard back yet but i will keep calling cuz i need a

tune asap and i hear they are pretty good. And oh yeah, this kit doesnt really make alot of top end power

anyway from what ive seen on other dynographs. So thats probably another scenario where the kit is still

doing what its made to do.

what boost gauge were you using out of curiosity? also have you checked out the accessport instead of using the e-manage?

Kjdakilla03

I dont even remember the name of the boost gauge but i will go in my shed and tk a look at it today when i get off. The access port is in my very near future. Rex u told me to get tha ap in another one of my post also! The only reason i am waiting on the ap right now is because i am planning on getting the MM upgrade. As a matter of fact i was on the virge of buying the upgrade last week and everyone (including u rex), was saying it would be better if i ran the upgrade on the access port rather than the eu. So since i only have enough for either the ap or the upgrade right now, what i chose to do was spend a lil bit now and tune the eu just to hold me over till my christmas bonus and then i can get both the ap and the mm upgrade at the same time. that way mm can go ahead and calibrate the ap for the upgrade instead of me getting the ap now and having it calibrated for the greddy kit then having to get it recalibrated for the upgrade a month later.

I see, good plan

your explanation of what was wrong sounds off . I'm pretty sure you didn't hit any fuel cut - perhaps just an overly rich or lean mixture .
Also - you should measure boost at the manifold - not at the turbo
Where did you plug in the vacuum line to the wastegate ? It should be on the turbo outlet - not the manifold ....

Kjdakilla03

i thought the greddy kit comes with a fuel cut at 5 psi thru from what i understand is controlled by the emanage ultimate. Thats what the instructions say anyway. And i measured boost directly off of the wastegate and off of the manifold. I got two different readings,shouldnt they have been the same? i also didnt mention that we hooked that boost controller up to another one of my friends cars. It is a boosted b16/eg hatch and it gave incorrect reading on his car also. I really wanna get whats was wrong figured out before November 21st cuz thats when my appointment for my tune at Top Speed is. I hear the tuner there scott is really good, he was on speed channel a couple of weeks ago. im looking forward to meeting him, but i dont wanna go up there with something screwed up.

im planning on upgrading injectors and after some research i was thinking about using two/four automatic injectors since they are 480cc. does anyone know anyone who has tried this? and would it be a good idea? i like the idea cuz there is nothing like oem reliability in my opinion. i couldnt find a thread on it either, can anyone help me out?

No fuel cut - just the wastegate spring; the jerking would be from an overrich mixture; or detonation.... the stock greddy timing is kind of ghey.

Just change the P2 injectors; you can change the others - but it messes with closed loop driving. You can scale them on the EMU; but I have heard mixed reviews.

I have stock P1 and Secondaries and 730cc P2's from MM that is enough for a LOT of power.

Stock Greddy on stock boost; there is no need to upgrade injectors.

First thing is to get a wideband - or tap into the factory one - pronto.

Kjdakilla03

thanks kane. I did a lil more research and found those same answers. MM had a really god thread on swapping the p2 injectors. i really gotta start searching before i ask questions that have easy found answers. im looking at getting injectors jus cuz i got a tune set up in a couple weeks and i figured to get the fuel pump and injectors before i go up there. so i can up the boost some. Detonation!? that sucks, i gotta get this thing figured out asap! hey kane what setup do u have? greddy?
