    My Thoughts on the eManage Ultimate

    I made a similar thread to this one for the eManage Blue (see my signature) and figured I would make one for the eManage Ultimate as well. There is a lot of information on the other forum if you search emanage ultimate as well.

    The Ultimate has several advantages over the Blue.

    One of my favorite is that you can adjust fuel based on MAP. I had my MAP sensor wired into the TPS input of my old Blue, but then I had to make a spreadsheet saying what "TPS %" corresponded with what PSI/etc and was a bit of a pain. It was also difficult to "calibrate" the TPS. With the Ultimate, I can wire everything normally and tune based on TPS OR MAP. Of course I am using MAP, but I still have the TPS wired in for things like the two step.

    The Ultimate also offers the ability to switch between two maps using the dip switches on the unit itself. This is great for people like me who plan to have an E85 map. This way when I need to fill up on pump again, I don't need my laptop.

    The Ultimate can do direct injector control. This means as I tune my car for whatever setup, my timing will NOT change. This is great for bigger injectors, ethanol conversions, etc. For my setup (9Bs) I plan to tune from wastegate to somewhere around 17-18 psi for the AFR the car wants. I will then make logs of various boost levels/timing and see what makes the most power. This is much better IMO, than adjusting airflow signal then randomly adding/taking away timing. With this setup I can keep stock timing but add advance where the 9Bs drop off, for example. This is also nice as you can tune AFR at idle. As some have noticed, with an SAFC, adjusting airflow at low Hz readings won't change anything as the ECU ignores airflow readings below a certain point. However, with the eManage you are actually adjusting at the injector level so as long as you tune for stoich it works fine.

    The Ultimate can also do little fancy things like MAP conversion, two step, etc. I have already played with the two step and I am excited to try it out once I get my TC brace on this week. At 3,700 RPM and WOT it builds about 3 psi of boost. I can also retard the timing a bit during this to build even more boost but I'm not sure if it's worth it yet as it will heat up the turbo a ton.

    The Ultimate also has a decent data logging feature which I plan to use with some type of virtual dyno software to adjust boost/timing for maximum power on the street.

    As with the Blue you can still adjust airflow if you want to get rid of fuel cut, and you can still use subinjector pins to control boost.

    It is also nice that the Ultimate uses a USB cable instead of a serial port.


    The downsides:
    If you want full injector control (stage 3), you need the CEL adapter which is about $60.

    It is a more intensive installation compared to the Blue.

    It is more expensive.

    I was originally looking at the Honda EMS but I think this is a great compromise between a standalone and a basic SAFC/SITC. I'm sure I will add more information as I use it more but hopefully this little review is helpful. I think this is one of the best piggybacks out there as I have fuel, timing, boost control and little things like two step all in one unit for ~$600.

    Hopefully I can make some decent power/times out of my 164,000 mile VR4 with this thing

    Let me know if you have any questions!


    (I would like to thank Ketihmac and Forest Gump for all their help with this stuff as well!)

    Glad you like it! Big improvement over the Blue/SAFC? I'm glad to see you went stage 3! You need to take it to the track again with the new setup.

    yeah I got some tuning to do first! Much better than the blue because of the additional options, but the blue was MUCH better than an SAFC.

    Once of the things I enjoy the most is the very fast datalogging the emu can do.

    I have a ton of tuning to do still, I have the airflow adjustment zero'd out and I am doing everything in i/j correction. Right now I have a part throttle lean spot and wot is so rich above 4500 it cuts out (pegged 10.0 AFR). Once I get that straightened out I'm going to set the boost limiting and tune that way so the computer gets stock numbers below 14.5 PSI.

    After I get that working well I'm ditching the maf. The tune will be pretty easy, I just haven't placed with it much, just got done doing my alignment which was a greater priority for me since I just got new tires and changed my struts.c

    Sounds fun Let me know how it goes without the MAF. If it goes smoothly I may follow in your footsteps!

    Would you still prefer this over an AEM or flash 99 ecu?

    I have the MAFT pro with speed density ready to install. I like it and I could always get the car to run OK on my old vr4 but I could never get the hang of it trying to tune it on my own.

    To be honest I've never tuned an AEM or a flashable ECU.

    I think each have their advantages.

    AEM offers full control which I LOVE but takes a long time to setup by yourself. The flashable is very nice (especially if you already have the ECU). If it would have come out sooner and could guarantee additional features like speed density and two step I would have gone this route if the price was comparable to the eManage Ultimate. I have a feeling it will be closer to $800 by the time it's all said and done, however (ECU, harness, cables, software, etc).

    I think the eManage is very easy to use in terms of software. They give you a map with a bunch of cells. Load on one axis, RPM on the other. Turn on MAP tracing and it will show you the cell you are currently in and ones you were in. Just look at logs/wideband/etc. and adjust the cells you were just in/are in currently. You can also tune based on MAP so one tune it good for whatever boost level you would like to run. All the maps are the same basically whether you are tuning fuel, timing, or boost.

    Let me know if you have any other questions!

    I've had one with all accessories in my garage for like a year now :| just cannot get the rest of the car to the stage where I feel I want more power yet.

    I love mine, stoich idle (all the time..) on PTE780`s with straight petrol is great!. I`ve changed fuel a few times (straight petrol/ E85/ Methanol mixes) and it`s nicce to only have to tune the fuel injector map and be done with it.
