Wez Posted October 25, 2009 Share Posted October 25, 2009 I see no technical reason why this is not possible, I am sure its been done for other ECUs ie Motec etc. One of the main reasons for choosing an AEM over other ECUs is that its plug compatible and you will be loosing this as you would have to wire it up as a piggy back, do you already own the AEM ECU or is it something you are looking to purchase?

Guest SupraGTE Posted October 25, 2009 Share Posted October 25, 2009 (edited) Hi Wez thank you for your reply, yes i have an AEM Ecu and it is controling also the the auto gearbox at the moment, but i do not trust it , but im looking to purchase a Stock ECU as i do not have that:) yes i will loose the plug in advantegd ... but thats life also i have gotten the recomandation to sell the AEM and buy HKs vpc and hks gcc Edited October 25, 2009 by SupraGTE (see edit history) Quote Link to comment Share on other sites More sharing options...
T2 MSW Posted October 25, 2009 Share Posted October 25, 2009 I have a stock TT auto ECU if your intrested in that. However its worth speaking to your mapper first to check this is possible with the AEM as its designed as a standalone ECU. Quote Link to comment Share on other sites More sharing options...
Tannhauser Posted October 25, 2009 Share Posted October 25, 2009 I looked into this a while back when I was unsuccessfully trying to run an AEM with my auto box. As far as I know, it hasn't been done with the AEM, at least in a Supra in the UK. The last time I checked this out on the AEM forums (a while back), I couldn't find any reference to anyone dong it elsewhere either, which surprised me. I contacted Thor Racing and was told that it was possible, but would involve making a bespoke harness. In some ways, it seems like an ideal compromise: let the AEM do what it does best (fuelling, timing) and leave out the bits it does badly (controlling the gearbox). As Wes says, other ECUs do it. In the end, the AEM had trashed a number of autoboxes and I didn't fancy being the first guinea-pig for testing the AEM as a piggy-back, so I went manual. Now I love my AEM and - touch wood - it works perfectly. Quote Link to comment Share on other sites More sharing options...
Guest SupraGTE Posted October 25, 2009 Share Posted October 25, 2009 (edited) Thanks for the info, yes i also conatced suprastore but they told me to go for vpc an gcc Ok seams like im going to be guinea-pig then , just would need somebody to help me wire it up as piggy back , preferable somebody with piggy back skills on supra I have the harness out of the car (in a box at the moment) Edited October 25, 2009 by SupraGTE (see edit history) Quote Link to comment Share on other sites More sharing options...

michel lane Posted October 25, 2009 Share Posted October 25, 2009 You have a AEM controlling everything CK, no piggyback unless this has been changed. Quote Link to comment Share on other sites More sharing options...

michel lane Posted October 25, 2009 Share Posted October 25, 2009 We finally got the AEM working with your torque convertor correctly, before anyone asks ...NO I am NOT touching another auto with an AEM.. it took many hours sorting CK car sorry many months with the aem tune and the autobox.

You can sell my auto box map for a small fortune if thats the case,cos the car handles just like a stock. Quote Link to comment Share on other sites More sharing options...
Guest SupraGTE Posted October 25, 2009 Share Posted October 25, 2009 I haft to say my car was also running very good , like a stock with AEM and and the AEM been in the car atleast for around 3 years but i do not trust the AEM as auto control it was a company in southampton that mapped it , now idea what company....im trying to contact the previous owner to ask...... but reading how the stock ECU controls the auto box and how the AEM does , then i really now want to keep my AEM far away frommy autobox.....

paul mac Posted October 25, 2009 Share Posted October 25, 2009 might be worth contacting Ryan at 2bar tuning i think he was talking about piggy backing a Solaris with an auto box Quote Link to comment Share on other sites More sharing options...

michel lane Posted October 25, 2009 Share Posted October 25, 2009 put some coolers on the autobox ...its heat that kills the boxes. Quote Link to comment Share on other sites More sharing options...
Guest SupraGTE Posted October 26, 2009 Share Posted October 26, 2009 put some coolers on the autobox ...its heat that kills the boxes. have one 23 row and second one on its way in, is that enough or recomend even more?, trying to find a fan(s) for these coolers also Quote Link to comment Share on other sites More sharing options...
dude Posted October 26, 2009 Share Posted October 26, 2009 Dude fit an HKS F con Pro with the knock amp and extra O2 sensor, the only ecu I would consider swapping mine for would be a Motec, this ecu is the nuts. Quote Link to comment Share on other sites More sharing options...
Nodalmighty Posted October 26, 2009 Share Posted October 26, 2009 It can be done, but there are two pit falls. IGF igniter signal conditioning for the factory ecu and signalling the AEM to do ignition retard prior to the gear change. I worked out how to do all this on a Link ecu using clever use of secondary maps and a box of tricks to intercept the solenoid driver lines, but it's not straight forward. I've done it on Supra MK2, MK3 (and one Mk4 but Auto) but MK3's don't have pre shift retard or IGF issues as they Auto ecu is a stand alone unit and can easily be fibbed to. You could always buy a PCS Gearbox ecu for about £500 and play with that. Lyndon. Quote Link to comment Share on other sites More sharing options...
Guest SupraGTE Posted October 26, 2009 Share Posted October 26, 2009 Soon i will put my twins back , thank you all for the information so far, how about greddy emanage? , suprastore recomends the vpc and Gcc , for the fcon any positive o negative sides, yes motec seams to be the diamond .... but it has a price also Quote Link to comment Share on other sites More sharing options...
dude Posted October 26, 2009 Share Posted October 26, 2009 Only drawback to the F Con is no traction control, I am more than happy with the choice I made, and remember I have a Motec just sitting here. Quote Link to comment Share on other sites More sharing options...
Wez Posted October 26, 2009 Share Posted October 26, 2009 Only drawback to the F Con is no traction control, I am more than happy with the choice I made, and remember I have a Motec just sitting here. Its a nice bit of kit but I would say another major drawback for the FCON is you are limited to who can map them, generally the mappers who do map them lock them down so you cant take it elsewhere if you are not 100% happy. As for Motecs, they are over priced Quote Link to comment Share on other sites More sharing options...
