[toMMy_O]

i bought this car used from a isuzu dealer...wondering if any mazda dealer
would know if it has been flashed or not???

A dealership can check if it's flashed by checking the vin number.

Here in TX, the dealer puts a little sticker on the left strut tower listing the new program and date...
