Please help,
anyone know how to read a fault code with an apex ECU fitted?
Been having the 'engine check light' flash up at high revs but car dont seem to over boost or 'Knock' any higher than normal.
Anyone got any ideas were to start??

is it quick flashing or does it stay on solid?

it started on a track day when the hose came off between the turbo and boost control valve, boost hit 1.5 bar and Knock hit 65, light flashed and fuel cut. so i limped to pits,after re-conecting the hose car was fine till it felt like it happened again but the hose was fine, boost was normal '1.2 bar' and knock was normal '16 max', but light flashed and felt like a fuel cut.
Since last post car is not boosting to what it should, 'only making 1 bar if that' even thow on 1.3 setting but no light flashing.
Car was running fine till that hose can off??? confused.com.

get your car checked out if i where you, i have had a simlar problem. my car is set to 1.4 bar boost and the last 10 days or so it dropped and fluctuated to around 1.2bar in 2nd and 3rd then 1.3 in 4th and 5th. on sat when i was blasting down the motorway my engine light came on got a knock of 77 and my engine then blew. i'm running a apexi also, thought i had a boost solanoid problem wish i'd have got it checked out more. hope this helps would'nt want anyone to have the same problem.

Yeah cheers, sounds similar. ive tryed changing the boost control solanoid, checked the turbo+acuator, checked cam+crank sensor, all hoses to and from the turbo for blocks or splits, starting to run out of ideas. got the map sensor and dump valve to check next.
Any other ideas would be very welcome.
Thanks everyone.
