richarde7927 Posted August 4, 2012 Share Posted August 4, 2012 Ok i have mapped my tt6 supra which i have just converted to single turbo on a emu, The car made 530 bhp on 1.4 bar and 578 bhp at 1.6 bar . But i cannot get the car to start on cold start or even when its hot it just floods the engine .I have to unplug the fuel pump get the car started and then reconnect once running .At that point it will run all day,Until you turn it off and go to restart. I have unpluged the fuel pump now to save flooding and removed the coil packs and plugs so it can turn over easier and save battery life. I have now be logging each time i turn the car over. As i remove fuel from the cold start the duty input and output go up . As the cold start was set it was around 22 ms on turning it over . So i added fuel to the cold start and it went down to 2.5 ms on crank. Which i do not understand . But the with no changes to the map . I just keep turning it over and logging 5 times in a row and everytime was different on a couple of time the injector duration spiked too a 100 % . Im about ready to take this ecu out and smash it as im almost sure its faulty and the case of all my problems . I really need help people this is doing my head right in and i want my car back on the road . Any help would be great Rich. Quote Link to comment Share on other sites More sharing options...

richarde7927 Posted August 5, 2012 Author Share Posted August 5, 2012 I have gone up to 850cc . I have set up the conversion on the emanage from 440cc to 850cc and put in the lag times. Rich. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted August 5, 2012 Share Posted August 5, 2012 Odd! i thought i had already replied to this yesterday, anyway sounds like it could be a stuck/faulty injector to me, thats not responding properly at low DCs, have you had them checked?

richarde7927 Posted August 5, 2012 Author Share Posted August 5, 2012 Thats the next step i think get the injectors out and tested . Would that course the datalog to show 100% duration on crank but not all the time its almost differant every time you crank the car. Rich.

Tricky-Ricky Posted August 5, 2012 Share Posted August 5, 2012 I would have thought that a stuck of malfunctioning injector could lead to to odd feedback logging, but i guess it depends on just how the EMU handles logs. Quote Link to comment Share on other sites More sharing options...
ADD Posted August 5, 2012 Share Posted August 5, 2012 Hi pal I was gonna use 850cc when i went single but was told that they are too big for the ecu to control. Is the car hard to start cold? When it does is there any smoke? Quote Link to comment Share on other sites More sharing options...

When it does is there any smoke? I'm running 1000CC Injector Dynamics with the emanage with zero problems I read something that the emanage had problems with a certain make of Injectors but i can't remember which make....

Alex Posted August 6, 2012 Share Posted August 6, 2012 A spike to 100% could be caused by a bad earth. Quote Link to comment Share on other sites More sharing options...
richarde7927 Posted August 6, 2012 Author Share Posted August 6, 2012 I run through the earths again. Rich. Quote Link to comment Share on other sites More sharing options...
richarde7927 Posted August 15, 2012 Author Share Posted August 15, 2012 I have finally sorted this . The emu wiring diagram is wrong in 2 places the coil packs have to be wired in firing order not series like they say . Plus this was my problem in this case the ecu earth and the injector sensor earth are the oppsite way around to there diagram. This has given me a headache for weeks im glad its finally sorted. Rich.

Tricky-Ricky Posted August 15, 2012 Share Posted August 15, 2012 Glad to hear you have it running OK now, don't remember any oddities in the manual, the coil packs should always be wired in firing order, and other than needing 12v and not 5v thats about it, you sure you don't have a Chinese EMU;) Quote Link to comment Share on other sites More sharing options...
Noz Posted August 15, 2012 Share Posted August 15, 2012 Glad to hear you got this sorted mate. I've had emanage troubles in the past with my air sensor so pleased to hear you got it sorted. Quote Link to comment Share on other sites More sharing options...
