Still working on it. It is still much simpler to send you DME in to us for a one time flash instead of pulling a piggyback in and out of your car for trips to the dealer, constant updates and code clearing sessions.

The custom map created for RPI's 135i was made to get the most power out of the car knowing their customers are limited by CA 91 octane. The software used in the RPI 135i car is similar to our Z4 35i file. Also if anyone is in the LA area you can have our Z4 software done at RPI.
