Bootmod3 Tune Questions
Hello M5/Bootmod3 owners. I’m new to the M5 platform and just purchased a BM3 tune. A couple questions if i may...
1. I’ve read on forums I need a battery charger to flash? This is new as when I’ve done a flash on my previous cars GT-R and S4 I didn’t need a battery charger. 2. I live in Washington and we have 92 octane. Would it be safe to run the 93 OTS tune instead of 91. If I do chance it with the 93 OTS tune, is there a knock safety feature that cuts boost or adjust timing? Thanks in advance. |

1. If your battery is good then you don't need a charger.
2. DO NOT use an octane rating which is less than recommended. If anything, always use a higher than recommended octane. This is especially important when running fuel from the US of A. |

Just make sure it flows at 20a when on charge as this is about how much it uses when uploading |

use battery charger for first time because it will unlock the DME first...
for octane get OTS 91 octane and use 92 octane... dont do 93 octane and you have 92... or boost your octane up with anything in the market good luck

i needed a battery charger cause my battery was like 3-4 years old....after replacing battery with a Brand new one i have not once used a charger. Have flashed over 50 times with Zero issues. If u have a new battery u r fine. If u have a battery that is over 3 years old u may need a charger........DME unlock takes 4-5 minutes. Map changing takes about 1.5 minutes....

If your voltage drops or something happens electrically wise during programming, you will regret that you didn't use a charger.
The Bootmod program will note to make sure battery voltage is stable. It is 100% recommended for the initial read out-programming Software updates occur within 1-2 minutes and do not require a voltage supply. |
