BIG problem tuning with GREDDY EMANAGE
While I'm waiting for my first base FI map from Jeff (does not run idle), my mechanic wants to tune the 8 (everybody tells me he is the best in PORTUGAL to tune your car, at the dyno).
In order to do so, he will use the Emanage Ultimate from greddy that comes with the bolt-on turbo kit.
Problem: the greddy emanage needs a specific rpm signal adapter (Item # Greddy 15900909)
Problem: that item has been discontinued by Greddy.
Question: Where can I find one?
My mechanic also doubts of the AP maps. He says that since the 8 doesn't have a MAP SENSOR, how can it read boost to calibrate the engine?
PLEASE HELP ME!!!! I've had my 8 on the shop for almost 3 months since we've started to modify it.
Thanks to everyone here.

Either he really is an idiot or something is being lost in translation. The "maps" created by MM have nothing to do with a "Map Sensor" (which our cars do not have). The RX-8 uses a MAF sensor.
But honestly do not use his (your mechanic) services. Use the Cobb AP and MM's tune and that is it. Yes it would be great to have MM tune your car on the dyno live but unless you wanna give him a vacation in Portugal, I don't see that happening.

Just tell me something: have you get your 8 tuned by MM? Live or by email? How much boost are you getting?

I just purchased a Cobb AP but my car is not turbocharged. However, most of my previous cars were so I have spent much money on tuning and dyno time. The Cobb AP is the best tool available for boosted RX-8's. I have seen MM's tunes and how they work on the dyno. I am sure ^ and some of the other experienced turbo guys will chime in but read the threads that are already here in the major Power subforum and you will learn a ton.

Another question: maybe this has already been answered, but here it goes: is the boost limited by the fuel injection (x fuel delivered by the injectors means x air flow) or can I manually increase boost with a boost controller? What implications can result from this?
I'm asking because the greddy turbo with the bnr upgrade can go to 25psi (it is what Bryan says) and I've seen that most of the people with the greddy turbo only show dyno graphics with 6, 9psi.
I don't know how to explain myself better...

The RX8 does not have a built in boost controller like the WRX and ms3,6 - since the 8 was not boosted from the factory.
The system will be based on how you design and build it. Read the Power Adders for Dummies thread, it is stickied here under Major Horsepower Upgrades, it may help make sense of things.

Thanks Kane. I've read the all thing. But my doubt is still this:
More air, more fuel. ok. I got bigger injectors so i can have more air in the engine. but how is that air pushed to the engine? will the turbo deliver the air according to the fuel capability or do/can i make the turbo to deliver more air manually until the fuel delivery capability? using a boost controller, for example. crap for my insufficient english...
can call me an *** because i'm learning... :P

You are confusing tuning with physics.... the air the motor takes in is based on the physics of your set-up (turbo, boost, piping etc) - the amount of fuel is based on the tune (assuming your injectors and pump don't max out on you).
So you mechanically set up the air delivery and then tune for the fuel..... this is actually an iterative process if you are smart, little air -> little tuning, add some more air -> more tuning..... and so on.
And all of that doesn't include timing.... which is a part of tuning too.

^ Where MM maps will do all this for you and all you need to do is follow his instructions. Use MM maps... pointless to use GReddy E-manage especially if you already have a Cobb and are waiting for MM's maps.

looooooooooooooooooooooooooooooooooooooooooooooooo ooooooooooool
You're the best, Jeff!!! :D
The guy is kind of skeptic relating long distance tuning. He says he can do better. that's why i'm insisting in getting the thing tune by him too. then, i can compare both tune ups.
By the way, i forgot to say that i've a Greddy BOV RS type.
Thanks again for sharing your knowledge.

Rodrigo: I have had Jeff tune my car in person and via email and I can say the results speak for themselves. While my car is not turbo'd, I have seen significant results with Jeff's tuning and what he has done for other turbo'd owners.
I think Jeff and I have put over 75+ RX-8's on the dyno together and he's tuned a great deal of them.
You will not find a better tuner for the RX-8 with the AccessPORT then Jeff.
I know your mechanic is skeptic of the AP because he's never used it and most of these tuners are used to traditional piggy back systems like the e-manage but the AccessPORT is a far superior tuning device and I'm sure he'll lighten up to it once he sees what it's capable of.

AP vs EMU thing aside...
I have discussed some of the problems with the default Emanage Ultimate maps. Someone else has already explained the pinout and the wiring and potential issues there. Search.
