Hello, I just installed the Greddy Turbo Kit... 10 to 12 hours my *** (maybe if the instructions didn't suck and we weren't using jack stands... oh and if my hands weren't so damn big)!! Anyway, I was hoping some of you people that are far smarter than me could answer some questions to help me solve my CEL. My kit is the stock Greddy turbo kit with the e-manage ultimate. It was ordered from Greddy back in April 08. I have followed the instructions as best as possible and have not added anything else to the rx. I have 6500 miles on it.

1. When installing the waste gate actuator hose, the Greddy instructions said to use one of the 2 plugged holes on the side of the intake manifold. Well, on my 07, those were no longer plugged, instead they had hoses connected that went to a T connector then to the oil fill tube. Not knowing what to do, my friend suggested we use the two ports as suggested by Greddy (second one for boost gauge) and put a T connector on one of the hoses that gets connected to the Greddy intake tube and connect it to the oil fill tube. Was this the right thing to do? My friend worried that since there was no apparent PCV valve that it wasn't a good idea to route the boosted intake manifold air in to the oil fill tube.

2. The air filter box had a green connector connected to some stuff on the back of the air box that had something to do with air flow, temp.. who knows. Anyway, this connector is just hanging there not connected to anything... is that correct? Would it be a bad idea to take the components off the airbox that the connecter was attached to and re-connect it all again?

3. Unfortunately, I do not have a scan tool yet, so I can not tell you what code it's throwing, however, if I disconnect the battery and clear the code, it will not come on again no matter how long I let it idle. It comes on under relatively strong acceleration (full 5.5 boost according to the boost gauge). Any ideas here would be greatly appreciated.

4. One last question unrelated to the CEL I'm getting, has anyone not put their e-manage inside the cabin, i.e. left it in the engine bay? I can easily put it in a fixed, well padded, water resistant container next to the batter and intake element. Would this be a problem? Is the a heat concern? I was going to drill through the fire wall, but the other side (inside the cabin) seemed very busy and I wasn't sure with all the stuff and padding, if I'd drill into something or not.

Thanks in advance for any good suggestions and for reading this long *** post.

OK... I guess I'll be the first to reply to my own post! I've been on vacation, so I haven't had much time to work on my 8. However, I have routed the emanage into the glove box as Greddy recommended. It wasn't as bad as I thought it would be. I also reset the CEL by disconnecting the battery. I tried the odometer reset and break pedal technique, but they didn't work. I installed one of the stock screens between the Greddy air filter and air intake tube. After reseting the CEL I drove about 15 miles at various speeds on a hot Virginia day, never at WOT, but at max boost several times and the CEL never came back. However, this evening after returning from vacation, I took the 8 out and in my first 5 minutes of a not even close to WOT drive I got a CEL. Tomorrow I will try to read the CEL I'm throwing. I wish there was a way to read it without the scan tool. If anyone has advice on what could be causing this CEL, I'd really appreciate it. Thanks.

Autozone will read the codes for free. Thats the easiest way to go. You can buy a scanner at autozone for like $30 and be done with it, and then you can turn the light off manually.

1. best source for the wastegate is to modify and place a vacuum nipple on your outlet pipe (hotside intercooler pipe) that connects to the turbo you can find this info on the greddy fix's thread
2. you can leave that connector loose its for the vfad which you will not use anymore
3. sounds like you are getting a misfire at WOT, best way to find out is to rent or purchase a scan tool which will only take 2-3 minutes to scan
4. best location is in the cabin away from heat, you will have enough other issues with the emanage my advise is if your budget allows get the cobb ap from MM and you can actually scan your check engine light codes at the same time

Good Luck

I bought a scan tool today and the code I'm throwing is P0661 (SSV Solenoid). Having a hard time locating this thing. I have access to the online workshop manual (removal/installation procedures) diagram and I'm still not sure how to get to it. This 8 is new with only 6500 miles on and with no prior problems, I just can't imagine the SSV solenoid has gone bad. Rather, I believe it is possible that a hose or connector to this solenoid is loose or off.

Possibly another symptom, is even with the CEL cleared if I try to get to red line, the fuel seems to cut out above 7k RPM and if I keep my foot barried in the pedal, it will eventually throw P0300 (random missfire). This doesn't occur normally, only if I keep my foot on the pedal above 7K RPM. Is this normal with the latest standard turn key Greddy kit or a symptom of an SSV problem?

If anyone can help me locate the SSV solenoid and trouble shoot it, I'd appreciate it. Thanks

the ssv solenoid is located as one of 3 attached to the plastic upper intake manifod located torward the firewall(you would have to have big hands!), it is vacumm triggered stock --not sure on your setup. But 1st just manipulate the arm on the valve itself to see if it is stuck for some reasson--probably not since it is a new car.

The GReddy E-Manage, as it comes wired from GReddy, opens the SSV in boost.
This freaks out the PCM because it didn't ask for it to be opened, but it sees that it was.
You will just have to live with that. (Until you graduate up to a better engine management solution, anyway.)
You will, eventually, get P0300/301/032 because of the way GReddy wires the e-Manage harness.
You will probably get a P2097 at some point as well.

Gregs answered your other questions, but you should read my GReddy threads since you would have had answers to all of these questions there.

So, if I understand this correctly, the SSV solenoid error and the not being able to get much past 7K RPM is normal with the latest greddy turbo kit? I read through your fixes, but didn't see one that addresses the SSV solenoid CEL specifically... I"m not that bright though... so maybe I missed it. I'm taking it to a reputable RX shop to have it tuned properly, will they be able to fix this long term with a conservative tune?

There is no fix for the SSV, unless you want to go to the trouble to build a "spoofing" circuit like I did.

Tuning the Ultimate is very, very tricky. I can't suggest any particular shop to tune it for you.
I have several E-Manage Ulitamate tuning files on my site, but they require that the harness be rewired to my specs as outlined in this post.

As far as not going past 7k, I don't know exactly what you mean. You should be able to get to redline just the same as before, though you will probably register some misfires and the boost will fall off at that point.

The GReddy is designed for only 6psi of boost. Add that to the fact it can't provide enough air at higher(7k) rpms your boost will drop to about 5-6psi above that point. Nothing should restrict you from going over 7k rpm with the GReddy. If there is something isnt right. The GReddy can run strong and be a really good setup providing you have the right engine management. As stated above I recommend you get the Cobb AcessPORT from Mazdamaniac. There is no tuning required as it reprograms the car's mapping system for you. That in turns eliminates any real issues that can't be solved in a matter of a few minutes if you have the maps from MM. I am intalling my turbo kit now so I know the frustrations. Mine is taking too long because of minor pain the *** crap. I learned a lot from MM and BHR as well as other people on here, most have posted in this thread. Good luck and keep reading, this place is very informative. I didn't know donkey crap about this car before I became a member a few years ago. Now I am pretty good but still need have questions at times.
