I visited my buddy last night who is a Ford engineer and now regional service-side exec to discuss my 2700 RPM bump. (He is also a Porsche owner and car nut.) He said, by the way, my issue is most likely a software issue and he let me know the crazy tweaks they do behind the scenes to the software in our ECU (I think Ford calls it their PDU?). I will visit my dealer today to discuss...
Anyway, he noted Ford has a really cool system called OASIS. He said if this issue was on a Ford, the dealer would give you a devise that plugs into your OBD2 socket and you just drive around. When your issue happens, you press a little button. The system then records engine data 30 seconds before and after you pushed the button (there must be a memory buffer that revolves data). The dealer then takes the unit, and the data is uploaded to Ford's database (located at Ford, not the dealer) and comes back with a recommendation for the dealer service tech. He implied the diagnosis was automatic..... but if required, an engineer reviews the data. Ford then uses this database to make tweaks to their programming and constantly updates the engine programming. They then occasionally will issue a TSB for say "rough idle at cold temps" where the tweak is applied but he also said there are many other changes not documented that address other minor issues in a given software release. Sometimes the resolution is for the dealer to just re-flash the PDU, others may be to replace a part.
I never heard of this system or how it works. Sounds really cool for both its technology, but it takes the diagnosis of odd problems away from the local tech and puts it in the right hands... the engineers at the helm.
Anyone have any direct experience with this Ford system?
