Browser based vehicle calibration editing software

Speedweaver wanted a SaaS web application that accepts a binary file from an ECU, matches this against a definition file and then determines all the relevant parts of the file which would be required to make modifications to provide value for enthusiasts.


Having completed some projects in the past with regards ECU file detection (PCW), we came to realize that it would be possible to provide the ability for users to modify their own ECU files.  Working with the team at PCW whose goal was to lower the burden on their team of specialist engineers manually calibrating client ECU files, we got to work prototyping how we could automate their daily grind.  After a few early versions of the file detection and parser we felt confident that this could be achieved.

What we did

After the prototyping phase and it’s conclusions we ran multiple design workshop meetings with the client to figure out which features would bring about the maximum impact for the smallest amount of work.  The SAAS product would be a subscription based product based on two different types of user, the professional who provided engine calibration services to clients and the enthusiast who may tinker with their own vehicle or the vehicles of their friends and family. 


Professional subscription

One cost for unlimited use.


Enthusiast subscription

Small monthly fee to retain projects and use of the editor.
