Methodology, software & labs

How you'll learn

100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetables: you progress at your own pace within the intake, so it fits around your job.

Each module combines theory, guided reading of the original standard and applied exercises. The working software is KISSsoft, Romax, MoTeC i2 Pro and OptimumLap, in free, academic or evaluation versions. Practical work is based on real procedures for gearbox strip-down and inspection, quickshifter calibration and gear ratio calculation. Assessment is continuous per module plus the final project.

Standards covered: ISO 6336; ISO 1328-1; ISO 281; Appendix J to the FIA International Sporting Code; FIA GT3 Technical Regulations; AGMA 2001-D04.

Assigned technical tutor:every module ends with a deliverable that your tutor marks individually.
Standards-based learning:guided reading of ISO 6336, ISO 1328-1 and ISO 281 applied to real cases, not as a theoretical annex.
Industry software:KISSsoft, Romax, MoTeC i2 Pro and OptimumLap, in free, academic or evaluation versions.
Final project:a competition transmission project choosing the gearbox type, ratios per circuit, actuation system and maintenance plan, reviewed by your tutor.
Flexible format:100% online, no fixed timetables, compatible with full-time work.

FAQ

Frequently asked questions

The programme totals 300 hours over 3 months. You set your own pace within each intake, and your tutor helps you plan the workload around your job.

You work with KISSsoft, Romax, MoTeC i2 Pro and OptimumLap, using free, academic or evaluation versions. Your tutor indicates the free alternative wherever one exists.

A SEIUM Institute certificate, awarded on passing the continuous assessment and the final project. It is SEIUM's own qualification, not an official state degree; its recognition depends on the programme completed and the regulations of each country.

Yes. Modules passed are recognised in a higher programme in the same area (postgraduate diploma or master's). Ask about the recognition policy when you enrol.

No prior qualification is required; you need a computer able to run the programme software, an internet connection and English sufficient to read technical standards.

Start dates are set by SEIUM's faculty for each intake. Our admissions team will confirm the next available date when you apply.
