greddy emanage ultimate questions
Ok I am installing the Emanage ULTIMATE into my car and I have a few questions, If you have the emanage blue or gold installed I believe the connections may be similar so any input would help
1. For jumpers 1-6 the manual indicates these are for injector input/output signal. It says leave the jumper open to use the injector map to trim and add fuel or connect 1-2 to add fuel only. Now im not sure which to do but it would seem better to go with the open option?
2. For jumper 7 the manual indicates this jumper is for the ignition input signal 1-2 is for normal (pull down type) and 2-3 is Honda distributor type (pull up type) now for this one the second option seems best because there are two crank angle wires indicated on the wiring diagram that Greddy provides and it two wires needed to wire it up as a Honda type (pull up type) I also read somewhere that this was the way the original emange is wired up. However I am not sure?
3. Jumper 8 is the Ignition Input Signal 1-2 is for a 5 volt system and 2-3 is for a 12 volt system. I believe the fc3s use a 12 volt however I am not sure.
4. Jumper 9 is for the Airflow/output signal leave the jumper open for normal (sensor signal increases as airflow increases) and 1-2 for Mazda hot wire system (signal decreases as airflow increases) Now my first instinct is to go with the Mazda hot wire system but I would like to be sure also the manual later mentions something about a Karman Vortex type air flow meter?
5. Lastly I have a question about my injectors. First I don’t know how to determine if my injectors are low or high impedance, I am puzzled because the donor car i took the ecu, wire harness, and engine from has the little resistor box I have read about ( the one that is supposed to boost the impedance, it is located under the factory air box and has a weird heat sink thing on it) but when I switched all the stuff out of the car I left that because it was on the harness that comes out of the drivers side. So how come my car is working without that resistor if I have low impendence injectors? (by the way both cars are 88) is there a way I can test them to know for sure what impedance my injectors are (and can I do this at the ecu instead of taking my manifold off?) if my impedance is low what’s the easiest way to boost it up, what resistor do I need exactly? And which wire do I put it on? Do I put one on each injector? I also had the idea of switching out for series 5 injectors I would just have to find some injectors because I already have the plugs, but I am not sure this would work because the ecu is still a series 4 but it should work because the emanage is designed to work with high impedance injectors only.
Sorry for all the questions I just like to deal in facts and find out the right way of installing something. It makes it hard when you read so many peoples different opinions and they all have something different to say. Any help on this would be greatly appreciated. (by the way when I am done I will make a highly detailed write up so those after me wont have this headache I do!

I have tried to install it myself with no luck yet.. I was told to use the Honda Pull up. All other jumpers remain as stock. But, I can not assure you of this. There is a guy on the UEM Yahoo groups that got it running great. Go there and post this. Please, please post your finding back here. Or, go into the Engine Management part of the forum and you will see a thread I started a long time ago about the UEM. Do a search for Greddy Ultamine E-Manage... Maybe between you and I we can get enough info to get it going.

1. think open is best
2.?
3. is 5volt
4. is increase as airflow increases
5. yours would be low since resistor pack increase ohms(resistance) to make ecu see high injectors(as long as you tap @ ecu you should be fine.
To test use a multimeter set to ohms and touch pins with points read out for low 2-4ohms
high 10-16

where there any answer go these questions im stuck. ive seen 12v and 5v for the ignition input signal. As far as the add and trim open for the inject chan that depends on how you have the emanage wired is it in series that would be the add and trim or are you in paralled that would be 1-2 add only. becuase in parallel you can only add more ground to the signal.
