So I don't know why all tuners hate the emanage. I did a lot of studying and reading on it and decided to tune it myself on my greddy turbo.

Now first a quick background on myself. I'm a diy person. I am a very fast learner as well. Went to school for computer science and auto body. I have done motor swaps, tranny swaps and more.

anyways back to he subject.
Me and my friend went to an open road to tune. And since greddy has a live tune ability it makes it so easier. We started with the greddy tune and modified from there, we all know that tune is pig rich.
So with my laptop in hand and my wideband hooked up and two different data logging softwares. We ran some runs on greddys tune and recorded afr, boost, factory map, and more.
After that we used some math and started altering the tune. Within an hour and half I was running at 11.5 to 11.9 afr at full boost. 10 times better then the greddy tune. The vtec crossover was the worst part of greddy tune, but now its so smooth.

I have yet to go to a dyno to fine tune but I will eventually just go rent one out for a few hours..

I do realise why tuners hate this and that's because unless your full throttle the OEM ecu is fighting with the greddy piggyback, but you can still tune it pretty well. And once the ecu learns and changes its tune it will only take a few minutes to retune the portion that the ecu has adapted to.

Now that being said I don't recommend you do this yourself because you can seriously harm your car if you don't have ways to monitor everything. I may eventuslly make a tutorial on how to tune eventually.

 

Most tuners hate it because it is just a piggy back. There are so many other better options for tuning the car where you can modify any parameter you want without worrying about the ecu fighting the changes you make. You can pick up a used AEM 1052 for pretty cheap..

 

I do realise that there are so many better options. But for those who don't have an aem ....

 

Good job Stealth! I'm learning how to tune with the EMU as well. Did you tune it in open loop via the analog output?

 

yes open loop for full throttle. And are you referring to the air analog output that the greddy uses to adjust the fuel? If so yes.. We also went back and adjusted the tune in closed loop as well. Even though eventually the ecu will relearn and well have to do it again. But as easy as it is I'm not worried about it.

 

The Analog output that sends a >60% throttle signal to the ECU kicking it into open loop.

 

oh no I haven't down that yet. I have read about that as well on the forums.. Well see how this does. Once I get my boost controller I have to retune anyways so I might try that when the time comes.

and I believe it said you can set it to whatever you want. It doesnt have to be 60%. But obviously to low ruins drivability and is harder to tune on the emanage.

 

I read on a DSM forum that you can wire the EMU to control boost using the additional injector controls.

 

I haven't read that yet. But I was planning and using the secondary injector controls for the automatic wideband correct for small corrections in injector duty when I hook up my wideband to the greddy.

 

Hmm nice, you should definitely do a tutorial when you get the chance.
