GSR2007 Posted August 1, 2014 Share Posted August 1, 2014 Hi folks when fitting my fcd I spotted that my car has an A/T ecu?,the was was originally an na with w58 and was converted to TT the car seems to be running fine sometimes idles a bit lumpy and cuts out by searched the forum and diagnosed a faulty/dirty iacv which will be coming out the weekend,just said I'd ask would running the auto ecu be damaging to my engine down the line I'd rather change it than it doing damage to the health of the car thanks in advance Link to comment Share on other sites More sharing options...
straightsix Posted August 1, 2014 Share Posted August 1, 2014 It's fine on the Auto ECU - very common to leave the auto ECU in place when doing manual conversions Link to comment Share on other sites More sharing options...
David P Posted August 1, 2014 Share Posted August 1, 2014 I believe that an auto ECU retains timing retard for auto trans changes, which feels randomly odd when used with manual transmission. It won't damage your engine, but you'll find the car would have more power and be a better drive with a manual ECU. Link to comment Share on other sites More sharing options...
Fitz Posted August 1, 2014 Share Posted August 1, 2014 As above. Most likely the donor engine was from a TT Auto car and they took the ECU with it. Link to comment Share on other sites More sharing options...
straightsix Posted August 1, 2014 Share Posted August 1, 2014 Personally, if it were my car I'd want to get a manual ECU Link to comment Share on other sites More sharing options...

Dazzi Posted August 1, 2014 Share Posted August 1, 2014 I had an auto to Manual na and it had a right flat spot when booting it. Felt exactly like the pause before the auto box shifts down. A manual ecu sorted this Link to comment Share on other sites More sharing options...

GSR2007 Posted August 1, 2014 Author Share Posted August 1, 2014 (edited) I had an auto to Manual na and it had a right flat spot when booting it. Felt exactly like the pause before the auto box shifts down. A manual ecu sorted this Funny that you mention this, mine at times almost has like a lagging effect when planted,i thought maybe a boost leak and checked all pipes and were perfect,so hopefully it solves my problem,already got a pm about manual ecus from another member thanks again folks great help Edited August 1, 2014 by GSR2007 shocking punctuation (see edit history) Link to comment Share on other sites More sharing options...
