Z4M ECU software upgrade issues

[lrz]

Hi,

1. Where/How can I get the genuine factory ECU software file of the Z4MR?! your help needed.

2. Is Alpha-N Tune recommended over "regular" tune? Why? (I have Supersprint headers)

3. TTFS or Epic Motorsports?

Best regards.

1. Not sure.

2. Alpha-N is intended for mafless setups that generally have a csl style airbox and supporting mods, not for a header car.

3. TTFS only because I know the fella but by all accounts they are both quite good.

1. The dealer can be a last resort to flash back to the factory file. Does the car have a tune on it currently?

2. Alpha-N in my personal opinion is better, the car is more consistent and yields the maximum power potential that it can achieve. Having a MAF may be slightly smoother at lower rpm/part throttle.

3. Both are highly well-known tuners for this platform. Essentially go with whoever can give you a better deal or call each company and see what their customer service is like.
