In order to update an ECU previously purchased from Frankenstein Motorworks:

• Place an order for ECU update here.

• Remove all mounting brackets from ECU

• Package ECU with appropriate protection particularly to the plastic connector, the connector is not available for replacement.

• Include copy of invoice or just write the order number on a sheet of paper and include it in the box. This step is mandatory, I will do my best to match up ECUs with owners but there is no guarantee of this happening if the order number or the invoice is not included in the box.

• Ship it to the address on the bottom of the invoice that was e-mailed to you. If a signature requirement is added it may delay order fulfillment by a day or two.
