Engine Light Problem Help!

[MUZT3K]

hey guys, today i went to winton and put my car on the track, on the 4th run when i hit 7k rpm i noticed my engine light flicker and id lose all power no boost at all. and then i tought id put it on low boost and hit 7k rpm and see what happens, i hit 8k rpm with no problems, droped the clutch in low boost no problem, droped it in high boost, engine light and lose of boost at 7k rpm. i currently have a high flowed turbo, apexi power fc tuned by trent at status, but what i do have is stock injectors, im leaning towards that as the problem i have a feeling even thou it was tuned so the injectors can handle that psi just, that they are now failing am i correct? and also i had high boost tuned at 15psi and low at 11psi i think and now on high boost im only hitting 14psi.

any help would be much apprieciated

there are 4 things that will flash the engine check light

the FAQ will tell you

"Things such as airflow meter max value, injector max duty, excessive knock will cause the engine warning to flash."

thanks for that paul, so i take it my stock injectors cant handle the boost

insted of my creating another thread. id like to know what injectors can hold 20psi and are direct feed please. thanks

and a std sensor failing or going out of range

so before you start fixing things, you need to first isolate what it was

i would suggest given you have stock injectors, its likely to be that

but you should check

id recommend

MONITOR

4 CHANNEL

AIRFLOW

KNOCK

INJ DUTY

BOOST

PRESS NEXT

make sure its on digital read out (that is each item is a number)

press RIGHT to clear their top score

flog the car to redline

and see if the light comes on

check the max values for each

each have their own trigger value to make the engine check light come on

the FAQ tells you how to check it and change it

and the FAQ also includes online emulator if you are unsure what keys to press on the hand controller
