JamesJDMwagon Posted July 10, 2016 Share Posted July 10, 2016 None you should get a proper reprogramable one. But it you don't have £800 you could drop a z4 in it, extra 20 ponies it's an aggressive ecu I've been told (ignition advance) . Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted July 10, 2016 Author Share Posted July 10, 2016 Any problems with it Quote Link to comment Share on other sites More sharing options...
JamesJDMwagon Posted July 10, 2016 Share Posted July 10, 2016 Risky. In my opinion 99 octane is a must it raises the fuel cut and boost a little. You don't won't detonation. Don't tell anyone but I've got one in mine 😅 Just google Subaru z4 and the specs will be there Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted July 10, 2016 Author Share Posted July 10, 2016 I'm only running on that anyway do you think there is any point if I'm going to get the esl bord Quote Link to comment Share on other sites More sharing options...
JamesJDMwagon Posted July 10, 2016 Share Posted July 10, 2016 Go straight to esl if you can no point messing about. I want to as well but I just haven't had the time or money. I plan to get a proper job done but I saw a z4 on eBay for £40 so I slapped it in just to try it. While I save for a proper ecu Quote Link to comment Share on other sites More sharing options...
quit Posted July 11, 2016 Share Posted July 11, 2016 yeah just banging a ecu in is pretty silly really , they will go pop but the z4 is pretty safe as factory map etc should only get a little bad detonation Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted July 11, 2016 Share Posted July 11, 2016 I think the z4 runs yellow 440 injectors and a tdo5 16g. your 94 runs grey 380's so give both the z4 and your scoob a google first to make sure you have the same turbo and injectors first. As it will over fuel or over boost if they're not the same [emoji6] I've never taken the chance with a ecu lottery and always waited until I'm ready to remap before changing anything . It can get very expensive cutting corners on mapping if it goes kaboom If it's not broke .....upgrade it 😊 Quote Link to comment Share on other sites More sharing options...
JamesJDMwagon Posted July 11, 2016 Share Posted July 11, 2016 I think the z4 runs 380 injectors not 440 savage. Your right savage it's not worth playing the lottery with your engine. I'm still trying to find an apexi ecu it's the one I really want plus my turbo is apexi also 😊. But to answer the initial question z4 is a fairly 'safe' swap. But not worth it in the long run.

savage bulldogs Posted July 11, 2016 Share Posted July 11, 2016 Yeah I wasn't 100% sure what the z4 or the op scooby's model was so thought I'd mention too google em first . I'd probably be tempted to try a z4 if they matched but then that would be on my own car and if it went bang it would be my problem. I never advise anyone else to take a chance on unmapped mods . As 20 yr old performance engines sometimes go bang on the standard map if 1 of the previous owners has mistreated it at some point in its life . If it's not broke .....upgrade it 😊 1 Quote Link to comment Share on other sites More sharing options...
JamesJDMwagon Posted July 11, 2016 Share Posted July 11, 2016 Agreed mate. I stuck one in mine just because if it goes pop I have the tools and ability to pop a new engine in. But would recommend a professional remap. 1 Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted July 11, 2016 Author Share Posted July 11, 2016 Well I'm going to get the esl in a month or two and have picked up a z4 for £30 so will give it a go for a short while just take it easy I think Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted July 14, 2016 Author Share Posted July 14, 2016 Just put my z4 in and it runs like a dream pulls well and feels good had a fue little problems with the u8 and this seems to of stopped all of them Quote Link to comment Share on other sites More sharing options...
