The same guy that at CMP in Apr, pulled my DME, opened it and looked at my chip. The difference is that one inspection is rigorous and the other isn’t.[/quote]
And what’s to stop me from flashing the stock tune and then re-flashing right after inspection with the cheater tune? its even easier than swapping a chip. if this is solely for diags, it seems a bit overkill. esp since not all of us are even interested in looking at MS log outputs. swapping parts is perfectly acceptable to me and if that fails i will take the car to someone who can diagnose it better. I know my limitations both in skill set and time. I’m not trying to be a BMW Master Tech at this point in my life. Those who want diags could install a passive logger and be done with it, the rest of us will just keep things the way they are now.[/quote]
This was a standard post race inspection when they looked at the chips of the top 3 and one pulled at random. I was the random.
No one is going to be interested in logs until they’re tearing their hair out over an intermittant problem that seems to be defying a solution. I don’t care who you take the car to, if the mechanic can’t replicate the problem he’s not going to figure out the cause. And when the problem only occurs in 4th geat >5krpm, the mechanic is going to be hard pressed to replicate that unless he takes the car to a dyno.
BMW Master tech’s aren’t some kind of miracle worker. When he can’t replicate the problem and everything tests fine in the shop, what does he do? How much would it cost for the BMW Master tech to spend the day at a dyno with a pile of spare parts…thousands of dollars in his time, dyno time, and parts? You guys that have not gone thru this seriously underestimate just how difficult this kind of situation can be.
The passive logger idea sounds interesting, but no one has yet presented a finished product that can do the job. And the possibility has to be considered that the passive logger could create it’s own gremlins by affecting the DME’s inputs. Few ways of gathering info are truly “passive”.
