Precision Matters

ECM & Powersports Electronics Repair,
Done Right the First Time.

Send your ECM in with a prepaid shipping label — domestic or international, standard or priority — and we'll get to work the moment it lands on the bench. Track your repair from arrival to return.

Why Viking Diagnostics

Unrivaled accuracy. Thorough diagnostics.

Every unit is diagnosed, repaired, and bench-tested before it goes back out the door — no guesswork, no reflashed boards passed off as repairs.

Real Component-Level Repair

We repair the actual failed circuitry — knock sensing, injector drivers, power stages — instead of swapping in a reflashed unit.

Order Prioritization by Arrival

Your spot in the queue is set by when your unit physically arrives at the shop, tracked from the shipping label you print at checkout.

Domestic & International Shipping

Prepaid to/from labels at checkout — no more hunting down your own box and shipping account to send a unit in for repair.
