DANWB Posted April 29, 2018 Share Posted April 29, 2018 Hi I'm in great need of help and or advise!! I have a 2jzgte twin turbo (originally automatic, now R154 manual with standard ecu) Three questions if you don't mind, the first one is the most important. The car has been flat as a fart for quite a long while. Just recently when warming up it started to rattle (panic on :-/ ) Fortunately I found it was the Actuator located on the top part of the exhaust, the end was tapping on the metal thread (which I've adjusted up) long story short to get to the thread I had to strip the turbo heat shield off and a bit more to then find the turbo ( j-spec) chipped broken, hence the performance, well I hope :-). The turbo's have now been stripped repaired with steel blades both on the inlet and outlet on both 1 and 2 turbo's. The turbo repair shop said I will have to remap before use but I have a standard ecu in the car and do not want to go to the expense of replacing the ecu, is this true or can I just set the boost to a certain pressure? Secondly the turbos have cost a lot so I don't really want to be buying extra things for the engine, if it turns out that the vsv valves are also to blame can I do the true turbo conversion with both turbos running in parallel with no consequential damage to the turbos And the last question, cause it used to be an auto, while stationary it will only rev to 4000 rpm (I'm assuming it still thinks its in park) Can the ecu be tricked? I thank you for your help in advance, thanks Dan. Quote Link to comment Share on other sites More sharing options...
AC93 Posted April 29, 2018 Share Posted April 29, 2018 Wont need remapping, just use your boost controller to set the boost Quote Link to comment Share on other sites More sharing options...
DANWB Posted April 29, 2018 Author Share Posted April 29, 2018 Lovely thanks!! Any Recommended pressure? Quote Link to comment Share on other sites More sharing options...
jimjam92 Posted April 30, 2018 Share Posted April 30, 2018 My auto TT revs all the way to the limiter while in park? Stock twins and ecu. Quote Link to comment Share on other sites More sharing options...
AC93 Posted April 30, 2018 Share Posted April 30, 2018 Lovely thanks!! Any Recommended pressure? You can go upto 1.4bar on hybrids, but have a play around. Also my TT auto on stock twins revs past 4k rpm in park too, so not sure about that one Quote Link to comment Share on other sites More sharing options...
jcbt Posted April 30, 2018 Share Posted April 30, 2018 See you have a r154 conversion from auto so what ecu are you using have you changed it to a manual one? Quote Link to comment Share on other sites More sharing options...
DANWB Posted April 30, 2018 Author Share Posted April 30, 2018 Thanks for all your replys and OK maybe it's another fault. And it's the standard auto ecu I'm using thanks again !! Quote Link to comment Share on other sites More sharing options...
