Guest suprabad Posted July 11, 2009 Share Posted July 11, 2009 Im looking into a ecu upgrade---So im thinking about an aem management fic----Or a emanage blue....What is better??? I could use any help mates... Quote Link to comment Share on other sites More sharing options...

magictorch Posted July 11, 2009 Share Posted July 11, 2009 (edited) Full standalone ecu (AEM) is better than a piggyback ecu. Depends on your spec and budget i guess Edited July 11, 2009 by magictorch (see edit history) Quote Link to comment Share on other sites More sharing options...
JamieP Posted July 11, 2009 Share Posted July 11, 2009 If auto go with the E-manage. If Manual go with the AEM. Quote Link to comment Share on other sites More sharing options...

rob wild Posted July 11, 2009 Share Posted July 11, 2009 Im looking into a ecu upgrade---So im thinking about an aem management fic----Or a emanage blue....What is better??? I could use any help mates... Firstly to answer this you need to give us some details on your cars spec i.e. single turbo? Hybrid turbos? Injector size? Auto or Manual etc etc Also have you spoke to a mapper? If so what was his advice? its often recommend to find a 'good' mapper first and choose the ECU that they recommend. However the two ecu's are at different ends of the ecu 'food chain' with the EMB at the bottom. I've used both the EMB and AEM and really they are very different! The EMB is basically a signal fiddler and will allow you to add or remove fueling in the air flow map, as well as advancing or retarding the ignition timing. But the stock ECU is still controlling all the systems. Where as the AEM replaces the stock ECU and controls everything. However to EMB can be a cost effective way of controlling small single turbos installations. As Jamie said above I would avoid the AEM if you are AUTO as the AEM can not control the autobox effectively. Heres just an example of the two map's. You can see the difference in the resolution of the mapping. Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted July 11, 2009 Share Posted July 11, 2009 EMB/EMU resolution is 16X16, not the misrepresentation in the pic I think the std ECU is only 22X17 and the AEM is 17X21 I always think the label of "signal fudger" for piggybacks has rather damming connotations, when its not really the case, a stand alone ECU receives its input signals directly from engine electronics such as throttle, MAP, temp and injector/ignition feedback and in turn output according to mapping and parameters set. But in reality the piggyback does pretty much the same, it receives its set of signals from all the aforementioned sensors, but pre adjusted from the std ECU, which it then processes and outputs according to its own settings and maps, IMO pretty clever stuff which works! So i think the humble piggyback doesn't really deserve it menial label, and is in fact a bit of a craftsman in its own right;) Quote Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted July 11, 2009 Share Posted July 11, 2009 Full standalone ecu (AEM) is better than a piggyback ecu. Depends on your spec and budget i guess I thought AEM fic was piggyback just as emanage is? I also thought fic was mainly for obdII equipped cars.

I'm no expert on emu's or mapping but is not being able to advance ignition much of a drawback? From what I've been led to believe on turbo cars the idea is to run as little advance as you can get away with, which would mean leaving it or retarding it. Do you advance ignition much on single when mapping? Quote Link to comment Share on other sites More sharing options...

Do you advance ignition much on single when mapping? Quite the opposite in fact, if you run std turbos in TTC mode or a single turbo, you need to be able to advance the ignition timing in the lower loaded RPM sites as the std setup runs a fair bit of retard due to early spool up, so once you have later in the RPM range spool up from a different setup you need to then advance the timing, or it will feel sluggish and you get slower spool up.

That makes sense, the only thing I've tried tuning was my old honda that had a hondata s300 on it, but my honda's ignition was setup for na and so was pretty advanced everywhere.

rob wild Posted July 11, 2009 Share Posted July 11, 2009 EMB/EMU resolution is 16X16, not the misrepresentation in the pic I think the std ECU is only 22X17 and the AEM is 17X21 Misrepresentation? Its fairly clear that you can not see all of the cells on either picture? All I was trying to show is an example of what the maps looked like and the fact that AEM has a greater resolution I always think the label of "signal fudger" for piggybacks has rather damming connotations, when its not really the case, a stand alone ECU receives its input signals directly from engine electronics such as throttle, MAP, temp and injector/ignition feedback and in turn output according to mapping and parameters set. But in reality the piggyback does pretty much the same, it receives its set of signals from all the aforementioned sensors, but pre adjusted from the std ECU, which it then processes and outputs according to its own settings and maps, IMO pretty clever stuff which works! I think that is the point though with a piggy back. You have two devices doing the same thing which isn't efficient. For example take the transition point of when the second turbo comes on line with a piggy back its often very hard to 'map' that out and often you end up with the following: http://www.mkivsupra.net/vbb/attachment.php?attachmentid=90428&d=1238952610 And I found the same with my EMU as Matt: http://www.mkivsupra.net/vbb/showpost.php?p=2334955&postcount=12 Since going AEM my throttle response is quicker, especially when im on and off power. As well as getting on boost sooner. So i think the humble piggyback doesn't really deserve it menial label, and is in fact a bit of a craftsman in its own right;) Ironically I wish that I had kept my fuddler whoops e-manage as its been a trade off between the AEM's poor control of the autobox yet better control of the engine. I do think that EMB/U is an excellent piece of kit for the money but a standalone gives greater flexibility. Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted December 10, 2009 Share Posted December 10, 2009 I've just got one of these AEM FIC to try on a Single turbo auto tomorrow as im sick of EMU's not working in the latest batch. They were brilliant up until this last batch. Will let you know what i think but the price of them and the built in map sensor make it ideal for BPU owners who want abit more power.

L33 Posted December 10, 2009 Share Posted December 10, 2009 Ryan no pressure but if all goes well tomo you could be giving me the first bit of good news on that car this year lol. Can you talk to paul about this dodgy batch so i can send mine back please. Good luck tomo Quote Link to comment Share on other sites More sharing options...

L33 Posted December 11, 2009 Share Posted December 11, 2009 Well ive had two go on me thats why there trying the aem today so hopefully it works. The first one i bought im being ignored so cant see me getting money back on that, hopefully i can still get my money back on the second one cuz so far ive spent a grand and still no working car!

Tricky-Ricky Posted December 11, 2009 Share Posted December 11, 2009 Good luck with the AEM, are Greddy not in receivership? i'm wondering if a lot of the EMU about at the moment are Chinese copays. Quote Link to comment Share on other sites More sharing options...
