Can't wait to hear back about it.I'll update when I do!
What year is your beetle?Can't wait to hear back about it.
I just moved to California from rural Washington State, never had to do a SMOG before (the state has since done away with ALL smog checks) but passed stock with no issue in July. Wanting to do a tune myself (keeping DPF) but saw this same article on the tunes.
Some flash tools automatically modify the CVN and possibly emulate the checksum in order to try to make tunes more or less invisible, but I don't think any of them would apply to a vehicle of this age. You might have to flash it back to stock for it to pass.
I was wondering that too. Or maybe they're creating their own database from all the ones they're reading.I wonder now if the data from my ecu is stored in an online database. If I upgrade to a different stage tune will that compare with my previous smog data?
malone stated that the cvn is altered but should be okay if refreshed to stock.
