I recently received my TagFlash ECU Programmer from ecuhelpshop.com and successfully used it to read and write DCM6.2A via OBD without any issues.
For those who’d like visual proof, the images below depict the entire process – from connecting TagFlash to a Peugeot, to igniting the engine, and then reading/writing the ECU data DCM6.2A.
Stay tuned, as I’ll be sharing more test reports on the TagFlash ECU Programmer. I hope you find these insights helpful!
