crazy ecu , not sure what to do

[zaquanh]

on every sr20 ecu ive used , there is a led and a screw , you turn the screw start the car and it goes into diagnostic mode , led blinks blah blah blah

but on my black top e5 ecu

there is no led

when you turn the screw in both directions nothing changed , car drives regular?

it doesnt even look like there is a post for the led , theres a hole but nothing except the board inside ,

but i still have some problems and wanted to check codes , what should i do with that ? ive never seen this before
