Had my G25x into the dealer for an accessory installation this morning and, besides doing that work, when I looked at the ticket after getting to the office it also says they "Performed P0385 Recall" and then "G25 ECM REPRO ITB10-068-P0385". The only reference to P0385 I could find on google concerns a crank position sensor. Anybody know what this is?

 

got the answer to this: it is an ecu software update for high altitude (Denver) performance to adjust air/fuel mix to compensate for lower air pressure
