Hyundai & Kia SIM2K510: new Flex release and full model list

What is new in Flex 8.28.0.0?

Magicmotorsport released Hyundai and Kia Kefico SIM2K-510 support on 30 October 2026. Flex 8.28.0.0 adds OBD virtual-read calibration work and an OBD-on-bench real-read route when a virtual file is unavailable. Unlocking is automatic during the first real read or write.

CAN-FD versions are included, with the new FLX4.4 adapter required for writing. The published operations cover virtual read, read, write and map checksum. This is calibration access, not a promise of full-memory cloning or recovery from every failed ECU.

Which Hyundai and Kia models use SIM2K510?

The complete SIM2K-510 filter in Magicmotorsport's public Flex database returned 25 variants across 10 model names when checked on 30 October 2026. All 25 are below, including variants beyond the five launch-page examples. These are the manufacturer-listed applications, not an exhaustive claim about every worldwide vehicle or software version.

The model-series years are reproduced from that database. They describe its model records, not the first or last date this ECU was fitted. For example, an i40 record beginning in 2011 does not mean every 2011 i40 has SIM2K510. Check the actual ECU label and diagnostic hardware/software ID.

Power is shown in the database's PS and kW units. The launch article uses 114/134 HP examples, while the database lists 116/136 PS variants; these labels should not be treated as extra engine versions. MHEV means mild hybrid. A model badge, engine capacity or registration year alone cannot confirm the fitted ECU.

What should you send for a SIM2K510 tuning quote?

Send the registration, full postcode, exact engine and gearbox, mileage and the change you want from the vehicle. Add the ECU label or a diagnostic identification report, including hardware and software references, if available. Tell us whether it is a mild hybrid and whether previous tuning or dealer software updates have been carried out.

Northern Calibration enquiries are handled by Precision Remaps UK. We check the actual software, protocol, equipment requirements and vehicle condition before agreeing access, calibration scope, price or availability. Do not remove or post the ECU until the job has been accepted.

Stage 1 remapping, faults and sensible expectations

An access release creates a possible programming route; it does not establish a safe power figure for an individual car. A Stage 1 brief should consider existing engine and transmission condition, service history, current warnings and the owner's driving needs. No fixed bhp, torque or fuel-saving gain is promised from this list.

Explain any limp mode, DPF, EGR, SCR/AdBlue or other warning before requesting extra performance. A fault-finding enquiry and a tuning enquiry have different scopes. Ask for a calibration that retains the required emissions systems, and confirm insurance and warranty implications before proceeding.

SIM2K510 recovery, repair and cloning are separate enquiries

If the ECU stopped responding after programming, keep the original read, written file, identification reports and tool logs. Tell us exactly which operation failed and what the vehicle does now. Avoid repeated speculative writes while the history and supported recovery options are assessed.

For a suspected hardware failure or donor replacement, send the complete original and donor labels and the diagnostic findings. A virtual calibration read is not evidence that the original security and configuration data needed for cloning has been recovered. The new release alone does not confirm a supported clone or a plug-and-play replacement.

Workshop, northern mobile and UK postal enquiries

The workshop base is Burton upon Trent. Owners and garages in Manchester, Liverpool, Leeds, Sheffield, Newcastle and the wider North can send the same vehicle details for assessment. Mobile suitability and travel are checked by postcode; these locations are service areas, not additional branches.

Where an accepted job needs a removed controller, agree the parts, packing and return arrangements before dispatch. Postal support can suit garages that will remove, refit and complete vehicle-side checks. A listed bench route does not mean every tuning or non-start job can be completed by post.
