Default Emanage + Aquamist 2c

Anyone had any success in controlling a 2c setup via the Emanages Sub injector map?

I just setup my 2.5 with a total E-manage/sensors setup and had not even thought about doing that. Thanks for the idea, I may give that a try at some point. How long have you had your E-manage? What kind of setup are you running ? Might be able to exchange some map info at some point.

Actually I havent even started playing with it yet. My semester ends the in earily may and I will start my intership and have money to throw around.

I have the emanage / support tool/ harness - used Ludespeed St. 2 T3 + old stage 3 intercooler / WRX injectors and pump / autometer a/f, oil p, EGT, fuel p, boost .

I am really looking forward to playing around with the 2c and emanage. There is a extremely good conversation about WI going on in EM&T

I am going to install my fuel upgrades and learn to dial back the fuel NA. Once I learn how the emanage runs the turbo will go on. It wont be till at least the middle of the summer as I still need a clutch before the install.

Default WI Thoughts

Somebody correct me if I am wrong about this. But the advantage in using the emanage for both fuel and water is huge. The emanage has three maps for fuel namely - Airflow Adjustment - Additional Injection - and Sub injector map. Airflow adjustment is just what it sounds like. It modifies the MAP/MAF/etc. signal to the ECU just as the SAFC's and some others do - I understand the Additional Injection map to modify the injector signal coming from the ECU as it is heading to the injectors - The Sub Injector map is made to be able to control secondary injectors in the case where stock injectors are bieng maxed out.

Here is an Excerp from the Emanage Help File which is helpful:

---------- Emanage Help file ----------------
*Air Flow Adjustment Map

This is used to adjust the input signal of the Air Flow Meter or MAP Sensor to the ECU for fuel enrichment,or starvation.
This setting will add to the Air-Flow Adjust Volume (A.A.V)RPM Setup on the main unit.
When programming the Air Flow Adjustment Map with the PC,it is recommended to set all of the Air Flow Adjust Volume (A.A.V)RPM Setup on the Main Unit to ZERO.

*Additional Injection Map

This is used to increase the fuel injection by adding to the factory programmed Injector duty cycle.The injector signal (duty cycle)is altered according to this Map for fine-tuning.
The additional range is 0-100%.However,the duty cycle of the injector cannot exceed 100%.
When using the Boost Limiter Cut feature,programming of this Additional Injection Map is required.

*Sub-Injector Map

This feature can be used if the application requires more fuel than the main injectors can provide.
This feature will drive additional sub-injectors once every two rpm signal pulse.
Either injector duty cycle or duration can be selected as the numerical value in Map table.

The injector duty cycle range is 0-100%
When a value higher than 95%is entered,the value will be displayed in RED.

*Ignition Timing Adjustment Map

This allows the tuner to adjust the factory ignition timing.
Input "+"for advancing and "-"for retarding the timing.The adjustability range is -20-to +20-
------------------ end Emanage Help file ----------------


From what I have read the addition of the Sub and additional injector maps over a ordinary FMU is where it will allow us to hook up WI with the ability to give it a resonable tune.

Although I admit IDC is definitely not the most ideal place to start for WI, the emagage has the ability to overcome alot of its weeknesses. The biggest weakness of using IDC is the fact that even if you are tuning your water with an aditional map, tuning water with your map is going to kill the fuel tuning you have done as you will have to pull fuel to compinsate for the water taking its place. As soon as you start re-tuning the fuel to compliment the water tuning you have done, your hosed because now you desrupted the IDC's coming to your WI controler and the water tune you spent so long tuning has gone down the drain. The thread I referenced above explains this in detail.

PLEASE correct me if I have misinterpreted the funcionality of the emanage as I only know what I have read, and have not installed mine as of yet.

What I see as the advantage in the emanage is the ability to modify the airflow signal as well as the IDC after the ECU does its stuff. The additional injection map will allow you to add or remove fuel independant of changing the airflow signal and thus allow MUCH easier water tuning. Using the Sub injector map to tune water 16x16 without having to constantly modify the IDC the water will use seems like a resonable setup. It's really like having 3 FMU's. One for an initial idea of the fuel before the ECU, and Two after the ECU to drive both the injectors and the WI separately. The ability to change the imput on the Sub Injection map to Pulse width change instead of IDC is interesting as well. There has to be a way to make something out of this!!!!

It won't get you the accuracy of the setup Vaus is planning, but it may allow us to get a decent tune of fuel and water out of a resonably cheap package such as the emanage without the major Headaces of the IDC systems we have seen.

again, I am no specialist in this area, just curious.

Just a note, the additional injection map will only let you add fuel. The only way to remove fuel is with the airflow map or the injector correction feature.

hmmm yes... I do remember that now

We can still remove the extra fuel we have added though. So the initial tune will have to be more in the additional map. Hmm. Running out of room would be a shame though.... halfway through the tune.

Thats a good point about using the injector correction feature for other than its intended use. I just scales all maps according to a simple old / new ratio right?

I wonder if it does scale ALL the maps. or simply the additional. I suppose it has to scale all of them which is troublesome for us.

actually the injector correction function just globally scales the MAP/MAF value, it doesn't effect any of the actual maps.
