dcarrter21 Posted January 28, 2011 Share Posted January 28, 2011 Im running the modified manual tt ecu by amuse. I just want more information on what it does as it seems to change the way it drives completely. Ie, how the power comes in etc!? Link to comment Share on other sites More sharing options...
johnny g Posted January 28, 2011 Share Posted January 28, 2011 It'll have a different ignition/fuelling map on there Link to comment Share on other sites More sharing options...
Nic Posted January 28, 2011 Share Posted January 28, 2011 It'll be mapped to give slightly better performance, it will also probably remove/raise the fuel cut and remove the speed cut. Link to comment Share on other sites More sharing options...
johnny g Posted January 28, 2011 Share Posted January 28, 2011 I've heard a rumour where ECU's like that actually retard ignition before boost then advance a little on boost to make it FEEL like it's coming on stronger. Link to comment Share on other sites More sharing options...
Wez Posted January 28, 2011 Share Posted January 28, 2011 Will prob also be mapped for a higher grade fuel Link to comment Share on other sites More sharing options...
Swampy442 Posted January 28, 2011 Share Posted January 28, 2011 As above, generic timing advance, boost/speed cut removal. Link to comment Share on other sites More sharing options...
dcarrter21 Posted January 28, 2011 Author Share Posted January 28, 2011 It feels like its running the turbos in Parallel, the rev limit is around 7.5k now. Do u think it would be good too get it on a dyno to check afr's and egt's? Ive only got oil temp and water temp guages to look at!? Link to comment Share on other sites More sharing options...
dcarrter21 Posted January 28, 2011 Author Share Posted January 28, 2011 Also its producing 1.15bar on hi boost Link to comment Share on other sites More sharing options...
Scott Posted January 28, 2011 Share Posted January 28, 2011 [-][/-]Also its producing 1.15bar on hi boost That is a boost controller though, not the ECU. Link to comment Share on other sites More sharing options...
dcarrter21 Posted January 28, 2011 Author Share Posted January 28, 2011 Yes i know, its a greddy profec 2. Just thought id mention what its boosting too.. Link to comment Share on other sites More sharing options...
Swampy442 Posted January 29, 2011 Share Posted January 29, 2011 If you have any doubts, get it dyno'd, they can monitor AFRs and up to boost accordingly Link to comment Share on other sites More sharing options...
Nic Posted January 29, 2011 Share Posted January 29, 2011 It feels like its running the turbos in Parallel, the rev limit is around 7.5k now. It won't be the ECU causing the turbos to run in parallel, but it could have been converted to run that way. What rpms do you get positive boost? It should be around 1.8K rpm if running sequentially or 3K+ rpm if running in parallel. Link to comment Share on other sites More sharing options...
dcarrter21 Posted January 29, 2011 Author Share Posted January 29, 2011 It was running seqencial before i changed the ecu, thats why im confused! Could it be the boost controller? As i know theres that setting that alters how quickly the wastegate opens? Link to comment Share on other sites More sharing options...
Lude Posted January 29, 2011 Share Posted January 29, 2011 think the boost is running a bit high, mine does that too, feels fast tho lol im getting an AFR gauge next, as i dont want the engine running lean, and scared that high boost will be lean PS where did you get the ECU from?

dcarrter21 Posted January 29, 2011 Author Share Posted January 29, 2011 1.15 bar is fine, i allways thought 1.2 was the limit??? A friend of mine got it with a turbo kit, im pretty sure its designed for bpu. Im gonna have a play with the boost controller! Link to comment Share on other sites More sharing options...
Lude Posted February 2, 2011 Share Posted February 2, 2011 sorry, thaught you said boost was 1.5, not 1.15 Link to comment Share on other sites More sharing options...
