What is the serial number of your MAPECU?

serial #: 000111

That is an old unit. You need a PC with a real COM port to update the firmware. A USB to serial adaptor will not work. Please find attached the instructions. If you think you can manage it, please send us an email to info@mapecu.com with your serial number so we can send you the files.

the attached file is either corrupted or not working correctly. I cannot view it.

Would you think it would beneficial for me to buy upgrade to map ecu 2/3?

I'll try again, but the forum is refusing to overwrite the corrupted one, grrr.

A MAPECU3 is going to give you a lot more tenability, especially ignition timing. What kind of vehicle do you have and what are your modifications?

great - the file works!

94 toyota supra 6 speed - single turbo t67 - 75lb injectors - obd 1 + map ecu - FMIC

edit: forgot to mention power goals = 550-600whp.

Also, this sounds great - I can perform these task to upgrade the firmware.

You are going to get more gains with the MAP3 because you can optimise fuel AND ignition timing, as well as all the other other features like two sets of tables you can select on the fly, etc.
