I tried Flagship One amd had code after code even after they said nothing was wrong with the ECU they replaced with a clone. It finally sent a code "ECU performance failure" so I got a refund. I tried Car Computer Exchange and was told my ECU was not repairable and charged me $200 I tried ECU PROS and they fix the problem. No fault codes, no hits, no misses. Just an ECU that made my Mercedes run like it did when it was new. I HIGHLY recommend ECU PROS !!!!!
