Siemens are a pain to do.
You can't read them via OBD to see what is on there, so writing always feels a bit risky.
Even writing you need to turn the ECU into boot mode.
So it's an ECU out job ideally to write them, and possibly a solder job if you want to see exactly what is on the chips before you write.
Also it's Siemens so a bit harder to remap, not as simple as a Bosch any way.
I do plan to get around to offering a tune on them but it's a big investment in time/kit to possibly do not many cars, and people with these now don't like to pay much money... it makes it a hard business model to justify, so it has generally sat on the back burner vs stuff that can make me a living unfortunately...
Almost all tuners just buy in files for these cars but I don't want to offer that. I either want to offer a proper tune I understand fully and know is good, or not offer anything.
