ROTABOOST Posted September 14, 2014 Share Posted September 14, 2014 Hi all, Had my EMU mapped by tuning developments a few months back. Car is running 245hp @ 1.1bar and has been running perfect. Just recently been having the engine light come on when I push hard in 3rd gear. Was bringing up code 12 (rpm signal) and 34 (boost signal). Cleared the codes by the EFI fuse, light came back a couple of days later and read it straight away and it had only logged 34, so that's the one causing the light. None of this before had any effect on the way the car was running. Today a new issue came up, went to overtake some idiot today and it shut down as soon as it went above 1bar.......I'm getting fuel cut 100% as the light comes on then goes off 2 secs later. How the hell can I be getting fuel cut when I'm running EMU???? Cheers guys Quote Link to post Share on other sites
ROTABOOST Posted September 14, 2014 Author Share Posted September 14, 2014 Ok just driven back from the mrs house, around 4 miles and it's back to normal!? What the hell is going on here lol, do you think it could possible be a faulty EMU? Quote Link to post Share on other sites
Matt1878 Posted September 14, 2014 Share Posted September 14, 2014 That's unusual mate.. Give mike a ring in the morning. Sure he would be happy to help! Quote Link to post Share on other sites
Gainzy Posted September 14, 2014 Share Posted September 14, 2014 I would be going to check that out asap overtaking with it shutting down fook that lol Quote Link to post Share on other sites
ROTABOOST Posted September 15, 2014 Author Share Posted September 15, 2014 Yeah it's very odd I still managed to get a check engine light, threw 34 again but no symptoms of fuel cut at all. Bloody thing! Got to be something up with it keep logging 34. I'll try and give him a call in the AM, I know they are in the middle of moving premises at the moment so might be a struggle Quote Link to post Share on other sites
JayJ Posted September 15, 2014 Share Posted September 15, 2014 Check the map sensor wiring/plug if it's loose. Sounds like a wiring problem, if the code comes randomly. Quote Link to post Share on other sites
ROTABOOST Posted September 15, 2014 Author Share Posted September 15, 2014 Not really random mate, every time I give it death basically, so it's pretty consistent, I'll check it though Quote Link to post Share on other sites
jordan walker Posted September 15, 2014 Share Posted September 15, 2014 Was the unit second hand? Or has it took a decent bat off something at any point?Ive heard that the emu's are very sensitive because theres a sensor near enough touching the inside of the casing and if the unit is chucked about and is hit in the wrong place it can cause you a hell of a headache so it might be that?

ROTABOOST Posted September 15, 2014 Author Share Posted September 15, 2014 (edited) It was second hand off here bud, but no signs of impact etc and has been running perfect for a couple of months. You never know it could have been dropped at some point but I've got no way of knowing :/ Edited September 15, 2014 by ROTABOOST Quote Link to post Share on other sites
Phil Posted September 15, 2014 Share Posted September 15, 2014 map sensor, swap with a pal and see how you get on. sounds like whatever voltage the emu is clamping the boost signal at isnt holding. so either maps sensor going mental/wiring from it is going mental and allowing the stock ecu to see too much boost. /shorting wire maybe?> Phil Quote Link to post Share on other sites
ROTABOOST Posted September 15, 2014 Author Share Posted September 15, 2014 Well that would tie in with the code 34 being thrown all the time, I priced a new map sensor from snows today for shits and giggles, yours for just £270+ vat haha! Will a glanza be the same? Mates is off the road at the moment so could be a prime opportunity ;) Quote Link to post Share on other sites
_shaun_ Posted September 16, 2014 Share Posted September 16, 2014 Id try blag a oem one to try first and take it from there I could be the oem one or the greddy one at fault Quote Link to post Share on other sites
ROTABOOST Posted September 16, 2014 Author Share Posted September 16, 2014 Yeah I'll swap out the original one first and see what comes of it, cheers lads Quote Link to post Share on other sites
Arnold Posted September 16, 2014 Share Posted September 16, 2014 (edited) Make sure you have the "E" version of the EMU, as earlier versions are known to have issues. The letter is stamped on the circuit board, inside the unit. Edited September 16, 2014 by Arnold Quote Link to post Share on other sites
ROTABOOST Posted September 16, 2014 Author Share Posted September 16, 2014 Isn't the E version the only one with launch control / anti lag? Quote Link to post Share on other sites
JayJ Posted September 17, 2014 Share Posted September 17, 2014 No, you can get it work with earlier versions too Quote Link to post Share on other sites
ROTABOOST Posted September 17, 2014 Author Share Posted September 17, 2014 Ah ok sir, tried calling mike @ TD, no answer as they are moving at the moment, sent him an email so hopefully get back to me soon. Quote Link to post Share on other sites
Duduglanza Posted September 17, 2014 Share Posted September 17, 2014 Try to log a run to see what the mapsensor is reading Quote Link to post Share on other sites
Phil Posted September 17, 2014 Share Posted September 17, 2014 Also the issue that appears at time with the earlier boards is solved using injector adaptor no.2 so unlikely to be related to a rpm/boost read issue. Phil Quote Link to post Share on other sites
ROTABOOST Posted September 17, 2014 Author Share Posted September 17, 2014 Ah I see so prob the board is ok then, I'm going to be going TD05 soon and heading for 320ish so I'm debating about going full standalone, wolf or link. Quote Link to post Share on other sites
