Mercedes Delphi CRD3, modified elsewhere. Limp mode, no stored fault codes, DPF unable to regenerate. In today's video we open the file to see exactly what the previous tuner got wrong.

If your current file supplier doesn't have the technical knowledge to back you up when something like this lands in your workshop, get in touch. This is what ByteFLASH is here for.

A Mercedes in limp mode, ZERO fault codes on every scan tool, and a...

What does a bad remap look like? This one destroyed two turbos and an engine on a Peugeot Boxer! We loaded the file into WinOLS and found disabled EGT protection, removed limp modes, rich AFR calibration and stripped out engine protections.

Full breakdown on YouTube - Show your customers why cheap tuning isn't always cheap in the end, and why you partner with ByteFLASH for your tuning files.

A Peugeot Boxer 2.2 BlueHDI came to us after a third party remap resulted in a blown turbo, followed shortly after by a complete engine failure. When we pull...

Can your customers actually see what a remap will do for their car before they even contact you? If not, you're making them work harder than they need to, and some of them will just move on.

We've built two ways to fix that. The free embedded widget drops onto any website with a single line of code. Customers pick their make, model and variant to instantly see Stage 1 power and torque gains. No developer needed, completely free to use.

The Vehicle Lookup API is for businesses that want full control. Build your own pages, in your own design, with your own branding and your own URL structure. Each response includes manufacturer logos, the ECU fitted to the vehicle, and stock versus tuned power and torque figures, everything you need to build a professional, fully branded remap calculator. That's also how you start ranking for searches like "Audi A4 Stage 1 remap" rather than hoping customers find you another way. API access is £350/year + VAT.

Both draw from the same ByteFLASH database covering thousands of vehicles, the same one that powers our own site and a growing number of ByteFLASH installer websites.

Compare both and check out the demo here: byteflash.co.uk/remap-calculator

🔓 Locked PSA MD1CS003? We've got you covered.

Post-June 2020 Bosch MD1CS003 ECUs, found in Peugeot and Citroen vehicles, have been the bane of many installers. Locked down and previously unwritable. Not anymore. AutoTuner now offer a mail-in unlock service!

No AutoTuner Tool? No problem. Ship us the ECU, tell us what you need, and we handle everything - unlock coordination, file installation, and return - ready to refit.

This unit came in from a ByteFLASH installer, went straight to AutoTuner for unlock, and came back to ByteFLASH HQ for read and software installation before heading back to the customer's vehicle.

The installer never had to lift a finger beyond pulling and re-fitting the ECU. That's the ByteFLASH end-to-end ECU processing service. Your customer gets the result. You keep the job. Contact us to find out more about our ECU processing service.
