Emanage ultimate controlling injection!!

[sk8er882]

EDIT!!! This is not going to hold up as I need at least 8watt resistors. The 1watts are going to heat up and fail. I wll update when I make a new circuit.

So after alot of playing with wires I was able to get the emanage ultimate to control fuel without the ecu shutting down injectors.

I originally cured the problem with 6 0.5watt 22ohm resistors. The key to making them work is to attach one side of the resistor to a switched 12v(the emanage hot wire is fine) and the other side of the resistor you splice inline w/ the factory ecu output/emanage input injector wires.

I also installed 6 diodes in troubleshooting in between the ecu and emanage as I thought I fixed the problem 2 nights ago. But that night I only was using one diode and noticed that that injectors was never dropped in the 20+ tries. When I installed 6 the problem was back to where it was. (I'm guessing that one diode that is also .5ohm load made the ecu drop the more troubled injectors instead of this one. kinda distributed the problem along to something else) So these are still wired in and although they probably aren't neccessary it is a good precaution to take as they will prevent any spikes/return voltage to your factory ecu.

Ok now after running the car for about 30min I opened my box and checked those resistors and they were hotter than they should be. Last night I went back to Radioshack and was looking for 1watt 20ohm resistors but they didn't have any. I found 1watt 10ohm resistors. By linking 2 of these in series you will get 20ohms. Radioshack only had 10 and I found one bigger resistor that was ~19ohm that I am using for the 6th injector wire. These new resistors will handle the voltage better and are the coated ones that are just better/longer lasting.

Ok so you hook up 12v and splice in 6 wires if you get a box from me or you can build your own circuit.

Workstation full of shaaat!


Prototype #1 DON"T USE THIS ONE!!!!1


Prototype #2 2 1watt 10ohm resisters in series for the first 5 then the last one is a singe 20ohm resister not sure of the wattage but it'll hold up.


Backside of board


Emanage so far, haven't wired in ignition but this is how I'm making the harness, plug and play so i can return to stock by removing a few plugs.


And heres a video. It's hard to hear but in the first scenes the car is dropping a injector after about 15secounds.


Pics and video removed for now. Will update this week.

Also with this piggyback you will now have control over you injection and ignition maps (I will explain how to do this process as soon as I finish my install). So anyone going turbo will be able to use this and take there car to a tuner who will have ability to adjust the fuel and ignition maps. No need for software or pricey custom ecu flashes/tunes.

what problem were you having with getting emanage to run your car? ive been running it for a year with no problems, and i didnt have to run resistors or diodes or anything crazy like that

you should try www.nteinc.com, they are an electronic components manufacturer in my area that offers pretty high quality components.

When wiring in injectors the car would run for about 15secounds then turn off injectors because the ecu was not seeing the correct voltage from the emanage.

What car are you running it on with no problems? This is the newer model, the ultimate, which allows you to control via the maps not by using MAF voltage.
