tommyep82 Posted February 15, 2016 Share Posted February 15, 2016 Was overtaking a car yesterday and car felt like it hit fuel cut engine light came on for a sec,I did flash code that showed code 12 and 34, 12 is rpm signal or knock sensor, code 34 is boost pressure signal, I'm running an emu ecu so car should not hit fuel cut it has not done it since but I still want to find what it could be thanks Quote Link to post Share on other sites

tommyep82 Posted February 15, 2016 Author Share Posted February 15, 2016 (edited) Any ideas lads wiring maybe? It's back to normal straight away and boosted perfectly Edited February 16, 2016 by tommyep82 Quote Link to post Share on other sites
gorganl2000 Posted February 17, 2016 Share Posted February 17, 2016 depends on how high your "new" boost cut is on the emuthe emu allows you to alter boost cut voltage across the rev range, if it is only slightly above the old limit, then you can still get fuel cuts at higher boost pressures by any chance when it happened did your car hit "extra" boost above your normal settings?.......was it a nice cold night/evening?

tommyep82 Posted February 17, 2016 Author Share Posted February 17, 2016 No it didn't I have the car on 1.4 boost (forged engine) and I had the car in low boost at 1 bar when this happened what wires my cause this, or could it be dodgy dizzy as well Quote Link to post Share on other sites
