Did you program it in fast mode or in normal (slow) mode? Highly suggest slow mode and verify at max and min voltage not just nominal.

Make sure the chip is properly seated in the socket.

It is a simple FLASH chip, there are no security bits or funny settings. It should just simply work unless you have damaged the chip with static electricity or damaged the ECU by bending the circuit board when you refitted the chip.

Don't think you will get much response on this forum, I am one of very few electronic engineers on here. But hope you get it going.
