Felt like fuel cut code 12 and 34

[tommyep82]

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

Knock sensor is code 52 👍🏻

Cheers mate both came up when I googled it

Any ideas lads wiring maybe? It's back to normal straight away and boosted perfectly

depends on how high your "new" boost cut is on the emu

the 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?

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
