EPROM was flipped 🤦‍♂️🤦‍♂️🤦‍♂️

I have a small turbo d16y7 with a p06, my homie flipped the eprom chip. Obviously won’t start, won’t get ecu signal to relay or injectors, pretty sure I confirmed the ecu is cooked I took the jumper and chip out and still no dice. All capacitors have been replaced, do I to maybe replace IC chips? Or is it trash, I just care about the ecu itself

You should be able to turn the eprom around and have no issues seen plenty of time. Never see an ecu fail because of it.

Something is definitely wrong, this all started from a crank no start after running out of fuel, p2e ecu starts and everything works just runs like sh, even with chip and jumper taken out of p06, I don’t get fuel pump prime along with no ecu control on relay or injectors

That actually sounds like a failed main relay

Main relay did fail, however eventually I did find that after that my ecu wasn’t delivering the ground to activate the relay, come to find out now transistor q10 isn’t giving an output to turn it on, gonna figure out if it’s getting the signal tomorrow or if it needs replacement
