yes it should work

To write a modified file, you need to buy a new clean chip (for ex. M27C1024), since the original chip is OTP and cannot be reprogrammed.
New chip is not flash and is also OTP - you can program it only once.
By the way, the original firmware dumps are freely available on the Internet.
Just read and publish the ECU ID information from the label.

No need to check.
You will find the Bosch B58548 chip there.
This is a re-labeled obsolete TMS27PC210-12FNT chip, and you can't buy it now.
Just buy the available analog - M27C1024 in PLCC44 package.

look for  ST M28F102... it wil work and you can flash as much as you need

If it´s not listed, then I guess is not suported

First I tried to read an old eprom M27C1024


 but there is a pin connection error


I've checked if the eprom is well plugged : it's OK.
So I don't know what wents wrong :-(

I've found a problem : the adapter was not wired correctly for 27C210 / 27C1024

This is how it's wired on the adapter


Pins 12 and 34 are not connected.
They should be connected to GND.
I've done the modification :


now the program can see the eprom, but there are still 2 inaccessible pins (contact has returned to 15).


I've tried with the second eprom, it does the same error.
So is there an other missing connection, or the problem comes from programmer ?
