Is remapping safe for your car?

A fully developed ECU remap is safe for your vehicle. Vehicle manufacturers source parts from third-party supply chains, with each provider being required to provide a warranty on the products, which are to be rated to a set specification. To ensure warranty claims are kept to a minimum and to ensure their products remain trusted as part of that supply chain, the manufacturers build in additional tolerances to ensure that their reputation is not put in danger. Couple this with a common shared platform to reduce production costs: a base model and a performance variant will often share identical hardware in terms of the drive train, and the difference is purely software. It is this combination of these third-party components and platform software restrictions that allows us the headroom to provide you with performance increases that are safe and reliable.

That is not to say you shouldn’t do your due diligence when selecting an ECU remap provider. The safety of an ECU remap is entirely dependent upon the knowledge and competence of the tuner developing it. The major risk in the market in which we now operate is from so-called tuners who load software onto the vehicle without truly understanding what the software is doing to the engine. There are many individuals and companies that use third-party software providers without a fundamental understanding of software and its effect on fuelling, boost pressures, ignition timing or torque delivery. This is where engine damage can arise from an ECU remap very easily.

Celtic Tuning truly develops all software in-house on our multiple Dynocom 4WD dyno cells. Every remap is developed, ensuring we monitor exhaust gas temperatures, fuelling, boost pressures and much more. We do not load software we have not developed, and we do not apply modifications that we don’t fully understand.
