Stu Posted July 30, 2012 Share Posted July 30, 2012 If that is the case, then the different linearisation would have been purely internal the calibration. Link to comment Share on other sites More sharing options...
opexo Posted December 21, 2012 Share Posted December 21, 2012 (edited) Hi, i am also interested in which is the first and which is the latest from the ECU's suitable for 2ltr conversion. And which has the better mapping like lesser flat spots etc.For the MAF differences - i've read that because of different aftermarket parts and brands and different production times, used materials etc even in the same factory there might be a difference in the readings of particular sensor there is around 10% (up to maybe 15%) tolerance from the readings of some sensors. Let's not forget that the ECU is self learning too, thus adapting. For the difference in the ECUs I think that it's hard to tell the difference from two ECUs after just swapping them and running for a couple of hours because the 'new' one haven't learned yet whereas the old one was. Maybe after the two were sitting around for a day to forget what they learned while a third one is used to warm up the car, then putting the tested ECUs in to see if there is initial difference, but i dunno.

Stu Posted December 22, 2012 Share Posted December 22, 2012 What is self-learning in an eec-iv ecu? Link to comment Share on other sites More sharing options...
opexo Posted December 22, 2012 Share Posted December 22, 2012 (edited) I tried to look for the original .pdf in which it was explained but i couldn't find it at the moment. But basically what i'm referring to is in the second post here. Edited December 22, 2012 by opexo Link to comment Share on other sites More sharing options...
Stu Posted December 22, 2012 Share Posted December 22, 2012 I wouldn't believe all you read. There are adaptive tables for closed-loop fuelling (oxygen sensor) and idle but that's about it. Link to comment Share on other sites More sharing options...
opexo Posted March 29, 2013 Share Posted March 29, 2013 (edited) Reviving the subject a little as now im free at last from university crap and i have some time to waste on le car ^^So still banging my head around the net for that 60-pin EEC-V marked ECU i have in the GTI i landed on that site HERE and looking at the codes i found that the last one of the letters are D, E, F, G for DESK, DEWY, DEEP, DALE. 93BB-12A650-ED / DESK93BB-12A650-EE / DEWY93BB-12A650-EF / 7145619 / DEEP Mondeo 2-4WD**93BB-12A650-EG / 1014287 / DALE ** - about that mondeo2-4wd - there are no mk2-4x4's out there, but i'll check this on my mk1 4x4 which btw i have to say honestly, of all fords i've seen how they run it works the best of all (in terms of no hesitation or near-none flatspot around certain revs) so i suspect that's the best ecu to look for. So i suspect after each "revision" of the ECU from 93 to 95 including, hardware or mapping, they've changed the letter with the next one in the alphabet. As in the first numbers (93 in the case) show the year which the part was firstly introduced, also seen on many other parts.

opexo Posted April 4, 2013 Share Posted April 4, 2013 As i promised above to check the ecu of my mk1 4x4 mondy sitting in front of me is DALE - "the last" one with possibly the best mapping. So indeed i'd suggest if anyone is looking for one of these ECUs after 2ltr engine swap to look for the later ones. SME-101 DALE EEC-IV93BB-12A650-EG *CEGR01C2WW1B* G CAD 5G07 9526 2204 OSRAME9AF 14A624 AA SYLVANIAFOAF-14A459-AA Link to comment Share on other sites More sharing options...
