Little Update on the Alpina Flash,

I am now getting a 2 mpg improvement in my Daily Drive. Yes 2 Mpg! The low rpm shifting program in Drive helps a ton.

How much mpg do you get?

So you are saying I need to take some time and do this :P My only worry is that I am still under warranty and they would notice the display change I am sure. I don't really want to flash every time I have to go in to the dealership either.

Can you get the flash they sell through the dealership like Rosey's car? Or maybe Dinan? Or Cobb since it takes only a few minutes to flash back to stock with the handheld?

The dealership flash is junk, adds 20hp for over $1k. Dinan is the same. Cobb leaves traces in the ECU that BMW can find even if you unflash it, is way more expensive than the JB4 and doesn't produce quite as much power even with a protune, stock maps are way down on power. JB4 has guage hijacking too which is cool (I can put boost, timing, AIT's, EGT's or whatever on the fuel and oil temp gauges). JB4 can also make all changes on the fly, including map changes, through the steering wheel buttons.

I checked out all the options before I decided on JB4 and I am really happy with it. After doing it once my install and uninstall time will probably be about 20 minutes so it isn't a huge deal.

If you were talking about the tranny flash, that is not available anywhere except to do it yourself. Normally it shows DS on the dash for sport mode but this puts the software from the Alpina B3 on it and is shows what gear you are in, S1, S2, etc. They would definitely notice that. I guess it just adds another 10 minutes in to my install and uninstall routine when I have to go to the dealer, which isn't often. Oil change is about every 10k miles. I might talk myself in to this yet :P

Dat MPG dough!

If BMW is anything like the Golden Valley Audi was, they didnt care that I modded software, shocks, springs, swaybars, exhaust and intake on my old A4 that was under warranty. They even replaced a leaky transmission free of charge.

You are too used to Mitsu warrantys. :) Just something to think about.

I am saying yes you need to do this. Total time to flash was 3 minutes. There is a flash counter that counts down from 65, I am currently @ 61.

I am pretty sure there is a box you can check that disables the countdown on the tranny, is there not? Been a few months since I looked at it much so I am a little fuzzy.

Peter - unfortunately they seem to be pretty picky about mods. I guess they will mark in the system that you have mods but not say anything to your face, then when something goes wrong you are SOL. I am not very happy with BMW as a company, but they make a hell of a car.
