well, i was just looking at this controller online and it seems like a very nice piggy back to be used with obd2 vehicles, however i realy dont wanna learn first hand whether they work or not? anyone use it or know of someone that used it and how was there experience?
We used one at Hybrid worked great after it was updated(one of the first units sold had issues go figure)
I know Mike @ Innovative has had great success with them and wishes people would use them over the greddy emanage shit.
Dude…Greddy Emanage is the most reliable piece of hardware on the planet. Nuclear missile launches should be authorized using it…
In all seriousness, the Greddy Emanage blue was the greatest thing since sliced bread for people who were used to the S-AFC 2 when the Emanage came out. It had timing control and you tuned it with a laptop on 3d tables. It was a BIG step up.
The problem was always hardware reliability. When it works, it does the job it’s designed for great. The problem is they like to die on people and Greddy is in big trouble now so their east coast office closed and support is harder to get than ever before. In the past it was a 4 week ordeal waiting for warranty replacement on them because they all had to go to Japan. Now it’s even longer.
Now that the AEM FIC is available there’s a more solid option…as long as we’re talking about the FIC 6. The FIC 8 has some issues they’re sorting out. I haven’t had any issues with an FIC 6. It has the Emanage Blue features and more.
By far the coolest feature…You don’t enter anything about the triggering pattern. You don’t tell it what kind of engine you’ve installed it on. You hook it up, run the car at two RPMs, and it figures out the triggering for the engine so it gets a proper tach signal. I don’t know how they did it, but it’s awesome.
Also if there ever is an issue, AEM is excellent about dealing with warranty issues very promptly. Nothing has to go overseas. They deal with it all at their offices in California.
there is a kid in ohio that goes to beaver run and he runs this aem unit on his turbo ka24 and it seems to work really well. the kid has never ever had a problem and said its really nice to use
hmmm, sounds like an excellent option for a late model car that needs to be turbo’d. Now a question for the ignition/fuel mapping. when tuning the variables does the aem read stock timing values? or do you need to know these and sorta start from scratch. like, how do you go about making timing and fuel changes? what values are being used?
I was going to try it when I was going to run more boost and larger injectors on my old SC setup. Had everything installed but unfortunately I was a victim of one of their defective units (it was an updated one, too). I sent it back to AEM to have it rebuilt but then I just ended up selling my SC kit.
I know a couple people that use it with great results. But Greddy EMU is a better solution. Offers the same features but it is road legal where as the AEM FIC is not.
Greddy emanage ultimate is only road legal if you’re running one of their CARB legal maps, and all the CARB legal parts on the car to run that map. There are almost no options out there for that.
I definitely wouldn’t say it’s an excellent option, but out of the basic piggybacks it’s a good option. I’d still rather properly tune the stock ECU or a standalone if either is an option.
It’s just offset tuning, like most piggybacks including the emanage. Like an s-afc you have your % adjust for airflow or MAP. Then it adds an additional injection value if you want, just like emanage blue. The stock ECU is still in control so if it’s using fuel trims your tune will float all over. The same goes for timing. You can add and subtract timing from whatever the ECU wants to run. You cannot prescribe specific result timing values. If the stock timing “curve” looks more like a fractal and it shifts around you cannot make it smooth. If it looks like a fractal, but doesn’t change, you can smooth it out.
from what i understand the aem has o2 inputs and what not to prevent the fuel trim floating issues so the ecu thinks everything is ok. Im still not 100% sure if the fueling/timing is controlled by offseting the maf signal. from what im told it doesnt. But then again, i havnt realy researched this too much so im kinda just curious at this point. There are no tuning options while maintaining obd2 compliance for late model bmws. I believe that HPfreeks uses this as well as AA for there late model bmw tuning needs.
Yes you can wire o2 sensors in and modify the signals to them, then watch fuel trims on a scanner, and keep adjusting until the fuel trims don’t affect things much. It’s a time consuming process.
Fuel is controlled by offsetting the MAF and the additional injection table.
Timing adjustment is in degrees or by %. Degrees are generally easier for me to work with so that’s how I do it.
I understand what you’re going for. I’m just not sure you’re going to be happy with drivability going back to a setup like this.
