We dealt with this stuff on Marc's Galant as well over a year ago. The point of the E-Manage is strictly a piggyback system, no adjusting the factory ECU needed or required, thus why it is a piggyback unit that intercepts data and changes it based on the settings within the piggyback unit (the E-Manage). Once you start tuning a piggyback unit, and go into the factory ECM, you have to go back and forth between the two which is spending more wasted time trying to tune something.
This is why the piggyback engine management systems are on the market, for those applications in which you do not have the money for a full standalone, or your factory ECM is not one which can be tuned/flashed.
I am not sure how far many of you have got with tuning E-Manage, but I can tell you the time Marc and I spent on this very unit on hs car, AFTER being tuned "professionally" here by a tuning shop who does mostly E-Manage and AEM tuning, we still had piss poor results. The way the system is setup is half assed and you simply cannot get anywhere near the results or control of the engine as you can with the OEM ECM. This is why Boomslang was making money for their harnesses because you could do far more with that ECM setup.
Marc and I both cautioned Jigz on the E-Manage and its poor user friendly way of tuning. You will literally spend more time trying to fine tune issues in the car than you will actually driving and enjoying it. There is very little resolution to the maps when compared to the Evo ECM option, and this was an issue we fought with fueling and timing, and Jigz has the same. Why do you think Marc has parked his Galant for over a year now after just trying to deal with the E-Manage? (Sure it may have something to do with an Evo LOL).
The days of piggyback are out, especially now with a highly active developer (Isaurio) working on the ROM files for this platform specifically. You can either stay within the limits of piggyback units, or make a huge step forward and run with an OEM ECU that has the same, if not more control than some standalones on the market currently.
