Do they really work? Which one would you guys recommend? Pros/Cons of each chip.

 

Osiris has a strong following on this board. Great reliability, multiple mapping, and outstanding gains. Make sure you go to a reputable tuner and you wont be disappointed.

 

Using any of these devices requires you to make all the mods first then find a knowledgeable tuner/dyno to make the correct adjustments. Like Diver or was that Deep mentioned, Osirus seems to be the best tuning tool for our cars....

WOW..Thats alot of information!

Thanks XET!

 

This thread has the potential to become a very information thread about tuning.

I have used the Greddy E-manage Ultimate for about 6 months on my G35 Coupe AT. ONLY for N/A mods, which are practically every bolt on including light weight pullys except for headers. Installation was really hard, had to hard solder each wire and that took about 3 hours. Tuning was ok, we didnt have that much knowledge about tuning, since we are locating on Guam, and not that much ppl here can tune VQ engines, but did have help from a professional mechanic and we did our best to tune it.

ONLY problem we encountered was the Greddy wasnt reading the coolant temp right, thats it, other than that it was a good EMS, car always started and it did run good.

Now I have uninstalled the Greddy, and I am using a Cobb Accessport, using Map Stage2 ATM for all the mods I have in my sig. The Cobb AP gave me a deffinate increase in HP I can feel it through all the gears, and the torque is there! NOW! you can even access the TUNER program through your laptop and tune your car through the ECU.

If you are N/A and want a tune for all your mods I would recommend the Cobb AP, plus they have support for Guam, and wont turn us away. If you have any questions Grevving6 let me know!

 

Looks like
Greddy E-Manage -1.

Cobb Accessport +1.

Osiris--Most chosen by members..(Hopefully we can get someone to contribute from this area)

Thank you Jberry! Good review...Yeah for sure, I will let you know if i have any questions. Thank your for your help & contributing to the thread!

 

^^^ no problem

 

Another?

Why didnt you include Utec in your list. It is very popular and pretty easy to tune

 

^ List updated. Thanks.

 

it's all very dependent on people's opinions and where they are from/what their tuner can work with.

also I wouldn't even think of buying one right now if all your mods are a z tube and k&n. getting a tune now would give you some power but then if you go buy more mods like exhaust, mrev2, spacer, headers, w/e it would just have been a waste of money getting it tuned because you would have to get retuned. and tuning isnt cheap

 

Not really. Alot of people share maps. And some of the systems allow street tuning that you can do yourself. I did my own Utec and saw some good gains.
