before i install the eat chip

[NY535iManual]

This is a little bit of a related question I guess, and I know next to nothing about electronics, but does anybody know as a practical matter how often chips & ecus are damaged by static electricity? I've always used the little paper/wire grounding "cuff" that comes with chips, but if somebody didn't how great is the danger?

so the m50 non-tu dosnt have a knock sensor?


and the m50-tu has one? My tank says 89 as the lowest grade of gas...which is midgrade.

In reality, I'd do a shogun reset, drive it for a week, then chip it. Only then will you find a better comparison.

yes to both. the m50 was kind of bleeding edge when it came out. while i'm sure that the knock sensor does an OK job with 89 octane, keep in mind that you still have a 10.5:1 compression ratio. technology really isn't able to overcome what grade of gas you can burn in such a motor. nobody assembling a motor from scratch would try to run 10.5-1 on anything less than premium. bmw may have been able to "engineer" a way around this, to an extent, but if i had an m50tu, i wouldn't bother running anything than premium. no, it isn't an alfa or anything with a 12-1 ratio, but its still an 11 year old car.
