How detailed is the installation? I was thinking about installing this kit myself, but saw on another thread that the kit needs to be tuned. What does the "tuning" involve? I thought that this kit was a bolt-on?
Any help with be appreciated.

Thanks

 

I think if you are having issues understanding tuning I'd say stay away from installing it yourself Turbos are complex and take a skilled technician 6-10+ hours to install...

 

I, along with some friends, are going to install the kit ourselfs. I really dont want to pay an extra grand for installation. All I need is someone to tell me what the tuning involves. I could install the kit myself and have a local shop tune it. So, what does all the tuning involve?

Thanks

 

no, seriously, 3rd power is right...do not attempt to install it yourself and then drive to a shop. You could destroy the engine before you got there. Plus, you don't want to take the car and kit to a shop and say here tune it when they have no idea how the whole kit came together and what it includes...please just work some kind of deal out with a reputable tuner on the install and tuning...

 

Ok, so I guess I could shellout the extra cash and have it done. But, I am still interested on what goes on in the tuning process. Could someone explain it to me? I would just like to have more knowledge on this kit and what it requires. I thought that the Greddy TT kit came with a new preprogramed ecu, does this not take care of the tuning part?

Also, I have read on other treads how, many people installed the kit themselves without tuning and then drove the car to a shop for the tuning and the car drove fine before tuning.

Thanks

 

thawk408, I can give you some tips. Tuning pretty much involves a dyno and a wideband O2 readout to double check to make sure the A/F is in acceptable limit between 11.5 - 12.5. The Greddy kit does come with an e-manage that is pre-programmed to operate at 5.6psi in conjunction with the pre-set wastegates (5.6psi). I've done my own install of my kit over a 2 week period taking every precaution and am satisfied with the install. Keep in mind the Greddy settings runs pretty rich. Installing this on your own is do-able but make sure you know you're way around a motor. Happy boosting..

 

Thanks 350Now for the info! That helps me very much on my quest for more knowledge. What did you do for tuning? Did you just drive it over to a nearby shop for it?

Thanks

 

Yeah I drove it to a shop that I know and are reputable. Tuning was just a dyno run with A/F check. You can definitely drive the car once you install the kit but don't push it until you have final tuning done. You want to make sure the e-manage Greddy gave you is functioning by supplying the correct amount of fuel, so tuning will capture this.

I want to emphasize, make sure you are comfortable working on your car because if you are not, definitely pay a reputable shop to do it. This is not an easy install ask others that did their install. There are plenty of information on this board unfortunately you might have to search for them.

Also try to install a boost guage ASAP to double check that you are not boosting some extreme amount of pressure.

 

350Now, could one hook up an OBD II monitoring system with a laptop and do a self tune?

 

Nope.. OBDII monitoring will tell you some info but there is no way to find out what your A/F is unless you get a wideband O2. Also you will want to tune on a dyno to get some A/F when the car is on load. In theory you can do this on the street but you have to know how to tune the fuel curve and timing. Also the Greddy e-manage only can hold 1 map which is the one that greddy provided. If you re-initialize you will erase the greddy map and start over.

 

How much would it cost to have a shop properly tune the car?

 

It depends on the shop but you will most likely pay for the dyno and then go from there. Dyno can range from $50 up. Make sure you do a dyno with a wideband o2 readout. So far I have not heard of a Greddy TT with an e-manage being incorrect.

 

If you dont mind me asking, how much did you pay for your tuning 350now? Also, what did you mean by "I have not heard of a Greddy TT with an e-manage being incorrect"? If they are not incorrect, then why have it tuned? Sorry about the newbie questions, I am just trying to get this software understood.

 

$100 for dyno run with wideband o2 reading (a little high you can find 3 dyno run with o2 reading cheaper). It's true that there are no Greddy TT with bad e-manage, but wouldn't you sleep better knowing that you're car and TT kit is within specs? It's just another layer of check on top of what Greddy provide to make sure everything is good. Hope this helps.

 

Thanks, it does help. So if the e-manage is working properly, does that mean that there is nothing for the shop to adjust? Or is there something that I dont know?

 

Pretty much. If e-manage is working properly you should be good to go with 5.6 psi. If you decide to up the boost later on with a boost controller you will need to have someone tune your fuel map. Also look into a timing control if you plan on higher boost levels.

 

I was planning on boosting it to 8psi. If I get my fuel map tuned with the higher boost does that mean that I can only run 8psi or can I still swith back down to the 5.6psi for daily driving, because you stated earlier that the Greddy e-manage only can hold 1 map? Also, what is the timing control that you talked about? And where can I pick one up?

 

Good discussion going on here..

Couple more points.

As 350Now stated, the kit is perfectly fine to drive at 5.6psi right out of the box. I also got a quick dyno check with wideband just to make sure everything was fine...it was.

Now, if you increase the boost, the key thing is to address the timing issue. If you have the profec e-01, when you increase the boost, it will see this and increase fuel accordingly, so you don't necessarily have to remap the entire fuel table. BUT...again....dno't try increasing the boost until you address the timing issue.

 

How much boost can the turbos run at without any problems? What's the max that they can handle?

 

I am not sure on the max psi, but one shop told me that with 8.5:1 pistons you can get the TT kit to crank out around 800HP.
