Z4M ECU software upgrade issues
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. Last edited by lrz; 04-12-2019 at 04:40 PM.. |

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. |

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.
