Take this file, it is from the older immo free ecu.
Just take a 27c256 eprom, put pin 1 from eprom in 3 of the socket.
So keep the ground pin of the eprom on the ground of the socket.
Pin 14 of eprom in pin 16 from the socket.

Then there must be an other problem.
I use this often also for race and drift cars.

When you use the original loom you have to bypass the fuelpump relay from the EWS unit.

I don't have a picture from the eprom socket but I hope you understand what I mean with the orientation of the eprom.

Look by the socket, you will see markings for pin one for the different chip types in white paint.
It might look like this on the PCB

I think it has 32-1 pointing to the normal position, and 28-1 pointing 2 pins PER SIDE back from the notch in the socket.

Fit the 28 DIL 2 pins back from the notch and it will work as normal.
The ECU is the same 075, but EWS versions had a larger socket fitted.
