adi2009 Posted July 17, 2007 Share Posted July 17, 2007 I ve just wired up my Emanage Ultimate into a fields harness and installed it. I m on stock injectors and stock turbos but once I connect the EMU to the supra the car runs rough and the RPM idles between 1250-1300. This is with everything zero'd (& I/J lag time set to 0.0). However, I did notice that the water temp reading on the data log never seems to exceed 55-59 deg C. Suspecting a busted water temp sensor, I ve even installed a new one today but that didnt sort out anything. Any clues on what the issue could be?

Tricky-Ricky Posted July 17, 2007 Share Posted July 17, 2007 I'm afraid you do need to input a lag time, if you configured it with the right engine code throttle set up etc, it should have automatically given a 440 injector size and a lag time of 0.09, if not try reconfiguring it, you may find that the lag is too high and will work better with around 0.04. Oh and there is a bug in the current software that stops the water temp from working. Link to comment Share on other sites More sharing options...
adi2009 Posted July 17, 2007 Author Share Posted July 17, 2007 Thanks for the reply mate! I initially left the standard lag time which was 0.40 and it was idling at 1330 RPM ish. When I reconfigured it to 0.00 then the idling dropped down marginally to 1250. Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 17, 2007 Share Posted July 17, 2007 If you had a lag time of 0.40 then the engine code is wrong, or something else has been input incorrectly. Link to comment Share on other sites More sharing options...
adi2009 Posted July 17, 2007 Author Share Posted July 17, 2007 Oh sorry, just checked and the default I/J lag time for 2JZ-GTE is 0.9 but either way, even with the default settings the car just starts running at much higher RPM. Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 17, 2007 Share Posted July 17, 2007 Like i said try lag of 0.04 and see if that brings RPM down, are you using a wideband? Link to comment Share on other sites More sharing options...
adi2009 Posted July 18, 2007 Author Share Posted July 18, 2007 I ve got a wideband but not installed yet since I m on stock turbos. Will only be installing it when I install the single setup. Tried 0.04 for I/J lag time but it made no difference. Just to confirm, the red wire on the Injector adapter #2 is supposed to connect to a 12v power source, right?

Ian C Posted July 18, 2007 Share Posted July 18, 2007 My lag times are set to 0.0 and 0.0 and it runs nicely It ran awful with 0.9 and 0.9! Try these: Before: 0cc, 0.0lag After 0cc, 0.0lag Before: 440cc, 0.0lag After: 440cc, 0.0lag Before: 440cc, 0.9lag After: 440cc, 0.0lag If any of them change anything significantly, mess about with the After lag time between 0.0 and 0.9. I think you can do this while teh engine is running so it'll be a quick diagnostic. -Ian Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 18, 2007 Share Posted July 18, 2007 Yes red wire is 12V, it does sound like you have a connection or configuration wrong, you have got the injector adaptor wired into the IN side of the EMU? Link to comment Share on other sites More sharing options...
adi2009 Posted July 19, 2007 Author Share Posted July 19, 2007 Ya I/J harness wired to the IN side of the EMU. Ian, I tried the combinations you ve mentioned, the only one that makes any difference is (Before: 440cc, 0.9lag After: 440cc, 0.0lag). The RPM just drops to 950-1000 momentarily but makes it way back to 1250 where it idles very rough and misfires when I blip the throttle. I m going to remove the EMU today and go over the wiring once again. Could something like this be caused by a faulty unit? Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 19, 2007 Share Posted July 19, 2007 Could be caused by a faulty unit, if yours is an early one as there was an issue with the ing transistors being knocked when people changed the jumpers and on sliding the circuit board back into the case, due to a design error,this caused a misfire, the serial numbers affected are posted on Mhodparts site, but its down at the moment as he is on holiday.
