Hey, my question is what map should I run with 93 fuel on jb4. I have BMS intake, akrapovich catback exhaust, ER catless down pipe, charge pipe and front mount intercooler.
I'm currently running Map 3 and my butt dyno is telling me that the car is a LOT faster feeling lol. The shop which installed the jb4 recommended map 3 but I'm wondering what maps you guys run? Also if I were to experiment and play with e85, I was also recommended map 3. From the n54 website I assumed that I should run map 2 or map 5 with my set up... Map 1: Additive target, around 4psi over stock. Map 2: Additive target, around 6psi over stock. Suggested for those with 93 octane and bolt on modifications. Also good for small E85 mixtures. Map 3: Progressive methanol mapping, absolute target of 11-20psi based on meth flow, meth additive setting, and average ignition values. Map 4: Stock performance with JB4 active for logging only. Map 5: Autotuning map, absolute target of 11-17psi based on octane and conditions. Map 6: User definable absolute target map. Suggested for troubleshooting by professionals only. Map 7: Race gas map. Absolute target of 18.5psi. Requires straight unleaded race gas.

Yes, refrain from Map 3...definitely run Map 5 as it's auto-tuning and will take under consideration several factors to help your F30 boost safely.
Is your 13' a PWG or an EWG? If it's the EWG, make sure you install the EWG cable so that the JB4 can regulate even more boost from the direct control of the WG. |

Map 2 may feel smoother and more consistent compared to Map 5. You'd really see the benefits of Map 5 if you were EWG or running E85 mixtures. However, no matter what the mods, you can never go wrong with Map 5. I keep mine on Map 5, have similar mods and it's great. I'm EWG though.

They definitely don't know shit about jb4, how can they sell something they dont know. Either way the maping modes are all over the place, dont know how you missed that one too if you are seeing that need meth kit to run map3. Quote:
Use map2 for pump and map5 with e85 and even better if map5 is to inconsistent for you, jump on map6 if you know how. I'm runing map2 on pump and map6 on e40. map 6 set from 12 to 17psi.

93 octane map 2 should give you the most power
E85 map 5 for daily driving, map 7 for racing

I'm FBO and using 94 octane. For now car is set on map 2. Waiting my Bluetooth kit to switch to map 5 and see logs. F33 EWG. Hope I can see a difference between map 2 and 5!

I'm not sure how, but I have the EWG and FF cables connected, am FBO and run 93 octane that has 10% E85 in it from the pump. I have just ran Map 5 from day 1 and sent the logs to them and they said they look good. Map 5 is the only one I can run that takes advantage of the EWG connector. I assume that has something to do with it.

Should run map 2 instead, would hit a constant 14.5 psi.

Very strange, this is what map 1 is supposed to give you. I would take logs and sent then to BMS to make sure everything is fine!

Map 2 does not utilize the EWG connector. If you are on 93 only, Map 5 is the only map that will utilize it for you.

Can you post your logs link? Consistent 17/18 psi on 93 is either really high octane or freezing weather.
